11/05/2013 v2.0
Clean up of some code... I had a copy of 1.0.8 from 2008 I recovered. I 
did
have a version 1.0.9 in production but can't seem to locate it for some
reason so starting from memory using 1.0.8. Thanks to Brett WA7V for
supplying me with some teaser code :-)

Updated version! We're on 2.0... finally! (yea, big news right? Maybe
not!)

Moved the "Who" commmand to the list of basic internal node commands.
I can't recall why on earth I had it defined with MOTD. Perhaps it may
come to me later but for now I can't recall. I may have to move it
somewhere else, but I believe it has to do something with logging
features or something along those lines. For now, you need to define
MOTD as a compile selective to have the <Who (call)> defined.

Fixed the sysop shell warning, this needed to be a tad more specific
in my point of view... then again who am I? Also cleaned up the return
prompt as it could be confusing if the incoming connection was done via
NetRom. I removed the default FlexNet Identifier out. Now it just says:
"Welcome back.".

In regards to the "Who" command; I see what was going on here and where
I left off with it! Logging and the "Who" command pretty much go hand in
hand - so they're combined. The initial design of FlexNode was to have a
MOTD based off of the logging of when the user last was on, otherwise if
they did not exist, push the "new user" screen to them. The down and
dirty quick fix is to simply remove it from netrom connections into the
system! Who cares if you get a MOTD on a flex/ax25 or a telnet connect
into the system!

With the above said, I changed the sequence of "configure" to ask if the
sysop/admin wishes to log user connects into the system. In the future I
will either move this to be included with protocols or I may simply hard
code it in as a defaulted option, and move the "Who" command as being
defined into TCP/IP functions. For now, it's hard coded in as a selected
option but will NOT display for NetRom connects.

While I was at it, I changed some of the routines in the configure script.
Nothing major but did improve upon a few things. While doing this, and
running "make upgrade" I noticed that flexd.conf was being overwritten!
OUCH! I'm surprised this went on for as long as it did. I *think* I did
this to force people to add the new lines in flexd.conf that K2BJG/SK had
asked me to do.

Created a man page for flexd.conf(5)! I'm surprised no one asked me why this
was missing! It explains further how to create the file. Keep in mind, this
also works on Xnet as well as Flexnet. If this doesn't help you figure out
how to create this file or edit the sample one... I don't honestly know what
to tell you. In doing such, it also forced me to change the generated
Makefile so that "install upgrade" and "install man" installs it.

Changed the licensing! This is (I'll admit) very personal and _must_
remain as is! I could fill a TB hard disk with reasons and debates
as to why it's no longer GPL code. Please insure you are in an area
where you can use this code. Thank you.

Fixed an ANSI bug I had in the "Users" command which was driving me nuts!
On NetRom, it would change the prompt to magenta which it shouldn't. What
I did as a fix was to force a removal of ANSI on the prompt for NetRom
based connects... simple enough. There may be other ANSIs for me to fix
and I'll cross those bridges when I get to them. Found another in gateway.c
and fixed the netrom ANSI to properly reflect that once a connection was
made, it was "systems GO" (green) without changing the Node's ID string.

Created a COLORS file which somewhat explains the hows/whys of not only
how I came up with a schema, but when it should and should NOT be used. 
It may also be used as a quick reference guide for the local sysop. It's 
a nice little cheat sheet one may print and keep near their keyboard if 
they want.

Added text to both the colors.hlp and help.hlp file for a users better
understanding of the color schema and how to gain colors to their terminal
if they so choose to have it. See my wishlist below for more information on
where I wish to go with this.

Added an item to the Wish List located further below in this file. With so
many spend-thrifty hams, do I really need to go through the code and match
it with the most up-to-date version(s) of GCC for compiling? I originally
developed the code using GCC version 2.95, now I'm compiling it on version
4.2.4 and it's not showing any errors during compile. If you have a specific
version of GCC you're using, please submit that and proper hardware for me
to run it on and I'll be more than happy to march forward :-)

Changed the inactivity timeout message so that it does NOT show
the FlexNet node call and gives a more specific message as to why the user
was disconnected. This was a call I originally edited and have now cleaned
up in node.c. There may be more of such messages. I can only test so much
and for so long :)

Made some more ANSI cleanups - in regards to Status and Users commands. I
had them as magenta and they should only be bright white as they don't
fit into any real category except for local system informations. For these
I had to make routine changes as well as ANSI changes in user.c and in
command.c. Also fixed the ANSI for version in NetRom. It currently had none.
This was done in command.c. Also cleaned up Links and Routes ANSI in command.c
and other places where needed. Originally I had the Routes as yellow which
even though it points the ax25-interface that NetRom is encapsulated under,
it's really more for NetRom "route"-ing... so changed it to cyan to keep with
the schema.

Found a disaster in ANSI routines for the Links command and the variant
switches along with it! The ANSI ran to the table which I did not want
to have happen and I believe I was very diligent in cleaning this up
in ver 1.0.8 or 1.0.9. In any event, I recall doing this and now I have
repeated my work... thus taken time away from more important tasks 
*sigh*.

These were worked in router.c. I also cleaned up other places where ANSI
ran over other strings that it shouldn't, and where it may have engaged
prior to where it should. Such instances are when it would highlight over
the Node-ID string (ex: MYNODE:mycall-5}). This really made my skin crawl
and I *know* I fixed this before... who knows perhaps I made a cleaner
routine than I had.

I recall doing a LOT of code clean-up, and it appears I need to revisit this
again. When I'm done, hopefully I can get rid of a few hundred lines of code
that's simply commented out for testing purposes only. The sizes of your
binaries should not be affected by this and I believe I've been diligent
to clean up the configure script to somewhat automate this process for you.
This task will be excessively time consuming! If anything it'd be an excuse
for a maintenance release!

Fixed a minor routine in ipc.c in regards to the Msg command. I deliberately
did NOT add ANSI to this because in a way the Msg command I feel is a tad
intrusive such as with an instant message, however I did clean up how an
incoming message was handled to the recipient. It now (in my opinion)
shows a cleaner screen.

I found Craig Small's old axdigi code and made an elf compile. In layman's
terms, it's a static binary and should run as-is for you. This binary
claims to be fully automagic in regards to crossport digipeating unless you
make changes to your interfaces in which you should restart it. This binary
also should NOT require /etc/ax25/axdigi.conf anymore. I have the other
binary so if you think you need it, let me know.

Added an install for axdigi in Makefile.in under "install bin".  Previously
this file was not included, now it is. I may write a shell script to launch
the daemons for you... keep an eye on this file for further info!

26/05/2013 v2.1

Fixed a bug in gateway.c where the finger "stop" ansi was white instead
of red (for stop). This was one I missed not having proper routing yet
to fully test. Thanks Brett WA7V for the link!!

Made another change in gateway.c in regards to the handling of the
flexnet destinations listing when using Flex/AX25 ONLY. There is a
reason for this (believe it or not) and that's in the shell and netrom
interfaces they both begin the destinations list with the string
"Flexnet Destinations:". This may cause neighbor URONode/AWZNode/etc
systems using flexd to improperly parse flexnet destinations from each
other. At the moment, I don't have the facilities to properly test this
but am hoping to work something out.

Thanks to Bob K2JJT, I added an include for socket.h in ipc.c. While I
never saw any errors here, I don't believe I've ever tested or compiled
on a Slackware system... Bob uses Slack. K2JJT reported adding this to
ipc.c helped him fix issues with his compile as it was griping about
AF_NETROM. Adding it here made no difference so since it helps Slackware
I'm all for being multi-distro compatable as much as humanly possible.

In reviewing 2.0 changes, it had me look more into the shell function
for sysops. I made a change that more defines which shell you may be
in when you do a 'w' or a 'who' in a linux shell via the node. This
was changed in system.c

Made a patch to node.c where if called from a shell, it would coredump.
Now, if it's called from a shell it simply exits back to the shell
prompt. I believe the same is in other "node" variants to which
the documentation directs the local sysop not to call the node from
a prompt, however KI6ZHD felt this was an issue. Being harmless in
nature to the function of my design I felt it wasn't harmful to add
it in. This patch was provided by David Ranch KI6ZHD. Thanks to him
for providing this, and eliminating any accidental core files on your
hard drives, and to Steven, K6SPI for coding the patch.

Thanks to David KI6ZHD for motivating me to do something I wanted to do
but put it way on the back burner, and to Barry K2MF for his elite C
skills. MHeard now will only print up to the 20 most recent heards. With
the initial routine, it would just dump either the global list heard
or if the user selected a specific interface the entire list for that
interface. At first, it worked fine for telnet and/or ax25/flex
connections but in NetRom it was double spacing. This was fixed by me. I
chose 20 to leave room for system headers and prompt returns. In a
standard 80x25 terminal screen, with a full listing, this should fill
the entire screen without a need for the end user to scroll up and
should help keep some traffic down on a busy network.

Made a change in gateway.c to eliminate the "trying state" message only
in NetRom when trying to connect to a remote NetRom node. This should
keep the node more in compliance with Software2000 specifications.

There was chatter within the BPQ32 user group on Yahoo that URONode was
not releasing any keep-alive timers. Please, this is NOT the duty of
a node Front End to control what the native protocol stack is designed
to do. This is totally sysop configurable. To flag this I strongly
suggest the following be added to your scripts:
echo "600000" > /proc/sys/net/ax25/ax0/idle_timeout
echo "600000" > /proc/sys/net/ax25/ax1/idle_timeout
echo "600000" > /proc/sys/net/ax25/ax2/idle_timeout
and so on... one line for each ax25 interface. This will break the
keep-alive virtual circuit Netrom AND IP will use for transport, and
thus break your IP as well. If you're running IP through an ax25
interface I suggest you leave this defaulted to 0 (disabled).

Rewrote the auto-find routine in gateway.c in do_connect so that first
order of preference for connects searches the destis table from flexd
BEFORE checking the netrom nodes and mheard tables, THEN it will search
for the destination in the netrom nodes if not found in the destis
table and prior to searching the mheard list. If you don't use flexnet,
then this shouldn't be an issue for you. As of this time, I'm unsure
if this would create any bugs if you don't define FlexNet during
the configure procedure. If it does, please file a report on the
online forum at https://www.n1uro.net/forum for me!

Made some changes in util.c and gateway.c in regards to duplicate ax25
route connection attempts. If you attempt to connect twice through the
same path, same call, etc, to clarify the error handling. This was
something I worked with K2MF on in regards to MFNOS. This does not mean
you can't make a connect on the same interface you came in on, you will
get a loop warning but the connect will attempt. If you connect from
the node, and try to connect to <callsign>, loop back into the node,
and try to connect to the same <callsign> again, you will NOT be allowed
to connect. URONode will tell you that a duplicate connection is not
allowed.

Cleaned up the do_routes routine in command.c. Shortened "Quality" to
"Qual" and renamed "Destinations" to "Nodes". After all, netrom doesn't
really use "Destinations", that's more a flexnet thing. Still more
cleanup to do in there *sigh*.

While I was at the do_routes, I noticed missing ansi in do_routes and
do_nodes. This has been fixed (and was previously in 1.0.10). I also
cleaned up the ansi routine in do_destinations in router.c to match
that of the netrom counterpart routines in command.c. Again, this was
done in 1.0.10 *double sigh*.

Rather than include an i686 elf of Craig Small's axdigi cross-port
digipeater which probably would NOT work on a Raspberry PI, I added
it into the Makefile by default. I also added an additional routine
in the configure script to check to insure that this file is made.

I also had to update axdigi.c so that it wouldn't error on the newer
(as if I run newer ha!) gcc. This was done for strcpy so that it
wouldn't produce errors as it does. I suspect in the "OLD" days of
linux/gcc it may have been OK as I consider Craig to be one of the
"village elders" of the packet system on linux.

Added a man page for axdigi. READ THIS VERY CAREFULLY!! To digi through
linux you *must* know some specific information and you might have to
educate your users on how exactly to cross-port digi through you if
they intend to do such. It's not something normally visible to them!
I may add a node-help file on digi...but for now please study the man
page on how. It works and works very slick as I've been testing it for
a couple of months. Mheard also will learn digi paths and use them to
connect to digipeated nodes if need be.

Cleaned up do_nodes in command.c. Shortened Quality to Qual, and the
equivilant of Obs. This will use less chars per line when doing a
node <node> or node * . I've been wanting to do this but saved
it for one of those rainy day things. Guess today was that rainy day?

Cleaned up more code and hope to have it finished before 2.1's final
release. So far I'm doing flexd.c at this point. FYI; code cleanup will
be a 2-fold process. First; I'll be formatting each file so it's at a
level of consistency. Second, things I have commented out for testing
that aren't needed may be permanently removed. I may leave a few things
in in case someone desires to say add a 'Welcome." message to netrom
(which is NOT Software2000 compliant!).

Speaking of which, I see I introduced a bug when ANSI is defined for
a specific user which violates Software2000 specs. I believe I did this
as a fail-safe in the prompt routine however now I see it's not needed
with all the other ANSI cleanups I've done. This change (deletion)
was done in node.c where I forced a shutoff of ANSI upon NetRom connects
only, as NetRom does not display the MOTD.

I rewrote a bit of the reconnect string. The "reconnect" in uronode.conf
should be set to OFF. All connections with the exception of NetRom WILL
reconnect. NetRom defaults to off, however with the {S|D} flags you may
manually request you stay connected. Eventually I will remove this flag
in the file so it will become moot. Please change it now to OFF! This
was done in gateway.c. Previously, these flags were moot in NetRom
connects. With the default to OFF, this keeps the NetRom in URONode
Software2000 compliant. A NetRom disconnect should *never* send any
text back whether it's a user or robot/script. Now a user can request
staying connected to URONode from a incoming NetRom connection. For
clarity sake, this only affects the user IF they connect INTO URONode
via NetRom. The "S" flag works for ax25/Flex/NetRom outbound connects.
A user connecting INTO URONode via ax25/Flex/IP will still automatically
be reconnected after an outbound connect.

N1UAN reports make install fails to install the config files. He's
correct. Changed Makefile.in so that "make install" also includes
make installconf which run by itself will install just the config
files for /etc/ax25.

I'm also working on changing the configure script to have some
"eye candy". This will be a continuing work in progress. You'll see it
as it comes. You will need the package "whiptail" in order to see this
new configuration routine. I don't know if this is standard amongst
ALL distributions, however I do know it comes default in debian and
debian based systems. If this *is* too much of an issue, I'll revert
back to the old method.

Almost forgot about an ANSI bug in extcmd.c where if you created an
external command in the node and the user was in via NetRom, when the
node issued "Welcome back." the ansi did NOT clear the color. I found
this in ver 2.0 and thought I fixed it, apparently not (age catching
up to me?) In any event, this is now fixed and working properly again.
Since most people don't use the +512 Color flags I'm sure it was missed.

Found a non-critical bug in cmdparse.s in regards to running external
commands - where it would automatically input a line feed before it
executed the command. This was the only routine which did this. A
routine like this really got under my skin and I was determined to find
and fix this finally... this was a routine I never changed, and that
was halted today (28 July 2013). Instead of totally removing this line
of code, I changed it to now display "Executing command... " and where
ANSI is defined, it is, naturally, green.

Found a non-critical bug in the Info command where it would show as
the first string to the user: "Help command for help" then it would push
the uronode.info file. This is very wrong. While the Info command does
use the routine of do_help in command.c, Info is an independent internal
command and this should not have occurred. This is now fixed with ANSI
if permissions display ANSI.

Updated the outdated INSTALL text document. It had some now misleading
pieces of information in it as some paths and make options have been
changed. Since no one has said anything to this, I'll assume no one
RTFM? (not surprised! email me and say in the subject line: surprise!
if you do!)

Went through the example config files and heavily commented them so for
new installs, it explains each line more specifically in hopes less
misconfigured systems will be created. I also found some typos as to
man page references - fixed. Also updated some of the help files in
regards to the new changes in relation to the "stay" sub command when
connecting out from URONode.

Note: in node.c I modified the pre-provided segfault patch to now
push text to the local console instructing the local sysop or user
what/how to properly execute the node. This will (I hope) force
some RTFM to occur. Syslog logging was also added in the event this
occurs. Actually, after thinking about this, I figured I'd dummy it up
a bit and have it launch a login anyway. This depends that the local
administrator/sysop -properly configures their box- and does the
following:
1 - add a line in /etc/services to point tcp/3694 to uronode
2 - add uronode as a service in inetd or xinetd
3 - insure you have a local telnet client on the box
4 - enjoy!
You will be reminded about this during the login, and syslog will
reflect a local console login as well.I strongly urge you not to open
2 shells and tail your syslog in one while you try to run URONode from
the console. Wink

Cleaned up a minor routine in do_nodes which lays in command.c where
under an incoming NetRom connect, a user who did "Nodes" received
an extra line feed if the columns were all equal at 4 per row. This
was a bit under my skin... fixed/changed. While I was at it, I changed
the output string when doing "Nodes *" from 'Nodes:' to "Detailed
nodes listing:' which actually makes more sense since it is a detailed
list.

Fixed a minor bug in the way the prompts were handled under certain
telnet clients. This was reported also by Marius Petrescu yo2loj. Under
telnet, I added a carriage return (/r) along with the line feed (/n).
Thank you Marius for the report.

Slightly rewrote the way meminfo() was being handled. While I may have
created a bug in 2.4 and lower kernels, this now should work in 2.6 and
higher kernels. I guess the phrase "if it's not broke don't fix it"
doesn't apply anymore?

FINALLY - split the CHANGES file into a new page!! This makes it easier
for me to input the change notes instead of having to scroll down for 30
seconds Smile Call me lazy but don't call me late for supper! <G>

04/09/2013 v2.2

Made multiple .c file edits to reflect the new libax25-devel .h files.
Currently these were pointing to the older kernel_*.h files and on newer
linux systems was preventing compile. Now URONode should work fine.

Added Marius Petrescu to the URONode team! With his c version of ripv2d, 
Marius will (and already has) make a huge impact on the future of 
URONode! Welcome Marius to the team! Made a reflection of this in the
configure script.

Marius brought to my attention the issue in the log timer routine where 
it was forcing 32-bit. He supplied code to fix this in both system.c and
flexd.c.

While in discussions, Marius brought it to my attention that Ubuntu (and
this includes Mint and any other Ubuntu backed distributions) where they
run as he calls it a "fortified libc6" which segfaults on every (what it
thinks is suspicious) buffer accesseD to prevent overflows however this
libc6 itself causes buffer overflowing. Why on earth did the Ubuntu team
ever do this?? Anyway, we're investigating how we're going to handle 
this issue. I personally have verified URONode to compile and work on 
the new kernel 3.x series on Debian and Fedora.

In "fixing" the prompt bug earlier reported by Marius, I made an error in 
the non-ANSI telnet prompt where the (/r) was also chopping off the first 
letter of a callsign! OOPS! This was reported by Ted K1YON. Fixed.

** Key news of this release: ROSE is a LOT more user friendly, AND it also
has the ability to display color screens to the end user. This now means
that URONode is an 8-prompt system! 4 main prompts, and 4 color prompts.
The prompt system is designed to show the end user what protocol/method
they used to connect into URONode with. Also proper SSIDs are displayed
to match that of how the end user connected. I did this because seeing
other nodes, they don't and when (as a user) connect into, for example,
a NetRom node who's ssid is -12 and the node displays something 
-=totally=- different, I often wonder if I connected to the proper node.

The new prompt schema is:
telnet   :	user@<sysop>.ampr.org:/uronode$
netrom   :	<none> - this keeps in spec with Software2000
flex/ax25:	=> 
rose     :	-=> 

Each matches with its own colors as well if you run the ansi flag. The
goodbye message for rose is also different than it is for flex/ax25 and
telnet links. The new RoseID flag is used as a personalized message to
the remote user to say a nice goodbye, and to remind them of your Rose
information. The (V)ersion command also has a rose column added to show
the remote user your rose information. An example of this is included
in the uronode.conf.5 man page.

With such, a new uronode.conf file string called RoseID has been created.
Details are in the file. You must keep the single quotes ' ' around the
string for it to display properly. You have been warned. Also, I've added
a default ExtCmd called ROSe so those who connect remotely can get rose
addresses for now. I'm sure I'll be changing this in the future.

Also, I decided to eliminate the permissions flag for use of hidden interfaces.
Reason being is if a sysop flags an interface to be hidden, they did so for a
specific reason. With that, I moved the ANSI flag from 512 in it's place to
64. This was also changed in the man page uronode.perms.5.

In regards to PBBS forwarding, I -=URGE=- you to read BBS.txt. Since
there's no need for me to rewrite it, please heed my warning here. This
is not something critical, just informational to help you improve your
link with URONode systems.

Fixed a cosmetic bug in regards to windows->linux emulation where when
logging in, sentences were not getting properly wrapped. This was done
in node.c. Other emulations such as PuTTY do not give you in windows
full linux-type emulation. Higher profile programs such as SecureCRT
will. For a free/shareware program I suggest MobiXterm. This also
gives you a raw Xserver emulated screen. Of course, there are no issues
if you use a standard linux console.

Added a .pid file to flexd, code supplied by Jaroslav, OK2JRQ and other
patches such as installer edits, etc. The only patches he supplied that I
have yet to add is the install location patch, and one he feels is good
for non-interactive. Source installs need to be interactive, if not you
would not be compliling - just my honest opinion. I can see in the case
of a possible distro package this may not be desired. The distros for now
can hash that out on their own. 

Many more cosmetic bugs fixed/changed. Moreso in ROSE but I did find a
few others in there which needed my attention. I have noticed windows terminal
based programs such as PuTTY have an issue determining \n based line feeds
vs \r carriage returns in C code. This mainly seems to affect the various
8 prompts. It seems if I put both in the code, Windows is happy but *nx
may issue an added line-feed. I had thought I cleaned these all up but
I introduced a couple old ones and some new ones with the ROSE work.

01/10/2014 -2.2 released!

02/10/2014 - 2.2.1

Improperly packaged an old flexd.c! This one should compile. This is NOT
the one I want, I've been fighting with flexd for a while now.

uronode.conf may not update. If it does, you will need to redo yours from
scratch. Look at the one in the etc/ directory in the source and add the
line for RoseId. This is required. Thanks for the above reports from
VE1JOT and SP2LOB.

Removed the need to have quotes around the RoseId string in URONode.conf. I 
found it unneccessary to have to do this. Keep the string togther ex: 
callsign-ssid@1000,200000 now is fine. I also find this cleaner.

12/10/2014 - v5.1
URONode release ver 51 is out!.. um.. I mean its main developer *sigh*

21/12/2014 - v2.3

Added Bob Tenty ve3tok to the development team and created a subversion
server. Please welcome Bob to the team!

Bob Tenty ve3tok reports when NOT using the official ax25 packages and
on Ubuntu, the node when compiled natively may buffer overflow. He made
changes to buffers in gateway.c, router.c, and flexd.c which prevent this.
I have incorporated these changes and there's no ill effect on non Ubuntu
distros.

Fixed a bug I introduced into the ROSE ansi prompt where it wasn't
executing a proper \n because I inadvertantly removed it. Restored.

Fixed a warning in the axdigi code. Now that I'm on a more modern system
I can fix these things as now I can see them better. This was also brought
to my attention by Tomasz SP2L... thanks Tomasz!

Figured out a way to compile and have it NOT segfault under Ubuntu. While
I'll admit for the time being it's somewhat of a hack, but it *does* work
for Ubuntu. There are warnings on Ubuntu compiles that don't exist on other
platforms - interesting to say the least - but I think I see a relation
between the warnings and the pervious Makefile. The prior statement is being
left in as a comment deliberately as I hope to try and revert back to
the previous method.

**IMPORTANT: Per distro downstreams, I've been asked to change the paths
of the URONode installs. Now your uronode and binaries will be placed in
/usr/local/sbin instead of /usr/sbin. Config files will be in 
/usr/local/etc/ax25 instead of /usr/ax25/. Node files will now be in
/usr/local/var/ax25/node or flexd instead of /var/ax25/node or flexd.
If you're a thrifty ham such as myself, you'll already have symlinks created
for easier management, so that /etc/ax25 is symlinked into /usr/local/etc/ax25
and so forth. Local files I can think of that would need editing if you use
my standard config:
/usr/local/bin/ax25
/etc/xinetd.d/uronode
/etc/xinetd.d/telnet (?)
/etc/ax25/ax25d.conf

Added a compile flag to keep Ubuntu happy. This and other routines were at the
suggestions of YO2LOJ and VE3TOK.

SYSop command does NOT spawn a shell anymore. This is due to the changes
with the UNIX98 file system. I'm debating on whether or not I wish to 
continue to keep this or possibly eliminate this (for possible security
reasons). I see both PROs and CONs with it. Note: this ONLY affects those
systems which force the use of /dev/ptmx in which one needs to use SOCAT
to create static /dev/tty*# and /dev/pty*# pipes. This only affects the
Kernel 3-series in which the older /dev/pty# system is no longer used and
a master ptyx is used.

I did notice UBUNTU made changes to their libraries last year (2013) in
which URONode compiled but failed to execute any direct disk read/write
routines. In any event, they fixed this bug late fall 2014 (at least in
12.0.4LTS). One of the nice things about Ubuntu doing this is that you 
can add a line in your grub configuration to have the kernel create a
number of satic pseudo terminals upon boot. Debian, however, breaks this
ruleset. I contacted my downstream and he hasn't responded. This would
help a sysop gain a shell... however also creates a possible backdoor.

Edited gateway.c so that the callsign-ssid is force altered on outbound
ax25 connect requests regardless of how the inbound connect was initiated.
VE1JOT reports that when a user telnets in, and gateway ax25 connects out,
the callsign-0 is kept. This should be altered to a -15. This was always 
true when inbound connects were ax25 and also outbound connects the same.
VE1JOT reports this is troublesome, and in some cases causing DM frames
to occur. While I tested this and found this not to be true on my own
system, I did make a code adjustment to handle this.

Fixed a bug in config.h which may cause flexd not to find the proper
config lines. When I changed file paths I missed a couple. Now the system as 
a whole should be consistant in regards to config files.

Removed the need for MyGate and MyRange in flexd.conf! This was added by
the request of K2BJG/SK so that the flexgate itself would be listed. Actually
it is in the LINKS file. Unfortunately when trying to connect to a listed
flexgate, it would try to digi via itself! Not good. While I was at it, I
also increased the buffer from 512 to 1024. This may help with those gates
that insist on making L A R G E MOTDs.


14/02/2015 - v2.3.1
Happy Valentine's day to the one we all love: Our Compilers!
This is a critical security patch! I URGE you *all* to recompile.
If anything, hopefully you've all patched your systems against GHOST.
For those who wish to test their system I have a tool on my ftp site
which can do this for you.

Through Paul G4APL, Andy G0HXT reported a condition on Ubuntu-based 
systems in which a user may enter a malformed NetRom connect string
into URONode and the node will buffer overflow. I fixed this in
gateway.c limiting the string for searching connects on the first parameter.
Also changed the error output to the user so that they may know the error
may be their own.

Made edits to all the man pages and the INSTALL file as suggested by Tomasz
SP2L. I also grepped for certain strings in other files and made a change
to the README file as well.

Changed the version in node.h to reflect this security patch.

Original Development Information (aka Disclaimer):
URONode was developed on an IBM eSeries 330 eServer with dual 1.2GHz CPUs
The OS is Debian Linux 4 using kernel 2.4.27, libax25 v0.0.11,
ax25-tools v0.0.8 and ax25-apps v0.0.6. This software comes with
absolutely NO guarantees so crash n burn at your own risk. We all may
be surprised and find out that it actually DOES something useful!
URONode may not run 100% depending on environmental conditions specific
to your system.

URONode is GLPv2 code, and tested by it's main author on the following
platforms: Raspberry Pi ver. B, Debian 7.7 on a Core-i3, Ubuntu 12.0.4LTS
on a Core-i3, Fedora ver. 19
