[Xastir] {Disarmed} Xastir Freezes

Curt and all, I found that Xastir is not grabbing the serial port since I can open the port with minicom while Xastir is supposed to have it.  I don't get a lockfile type of message saying it was in use by another application.

My speculation is one of the recent Debian 6 updates is causing the port to not open in Xastir.  Not sure which one though.

It
 sounds to me like permission issues.  On my OpenSuSE boxes I don't have
 that kind of a problem once I do the chmod 4755 bit or add the Xastir 
user to the proper groups and log out and back in to get those added 
permissions.

Maybe someone more versed in Debian has the answer.

The problem is that you probably have previously installed a binary version 
of Xastir from your system's repository --- and Linux packages are set up
to install files in /usr (e.g. binaries to /usr/bin, libraries to /usr/lib/,
and supporting files to /usr/share).  But CVS xastir, like almost all source
packages, installs to /usr/local (/usr/local/bin, /usr/local/lib, 
/usr/local/share).  When you de-installed your binary package and installed
the source version, it removed the /usr/ stuff and installed the files in
/usr/local/.

Your configuration files for Xastir still point to the old locations, and
Xastir is confused because files it's expecting aren't there.

You have two approaches to fix this:

  1) If you have not used Xastir a lot and don't have a whole lot of 
     custom configurations (map selections, interface properties, etc.) then
     you can just move your .xastir/config/xastir.cnf file and let Xastir
     regenerate a default set-up.  Many people here recommend that approach
     because it's just a matter of one command:  

        mv .xastir/config/xastir.cnf .xastir/config/xastir.cnf_old

     But this will blow away all your customizations, so it might not be the
     best choice.

  2) Change all references to /usr/ in your configuration files to /usr/local.
     Most of these will be in .xastir/config/xastir.cnf so it's just a matter
     of editing that one file and changing them all.  

This is one of the more common questions on this list, and for whatever reason
isn't in the FAQ file.

It is always an issue when you switch from a pre-compiled linux package to
a source build.

It's been added to the text FAQ and the online Wiki FAQ.  Thanks to Tom for such a complete answer.

Well, I managed to get the interface 0 hard fail to go away but I cannot prevent Xastir from freezing every time I open up the serial port with the Peet Ultimeter 2100 weather station on it.? I tried USB to serial interfaces and PCI to serial interfaces and I get the same result.? The Debian 6 box is fully talking to the TNC but why not the WX station serial port?? Why would it freeze Xastir?? 

Then I went as far as blowing away the entire OS, reinstalling, adding my user to the dialout and sudo groups and reinstalling Xastir.? I did the chmod 4755 to /usr/local/bin/xastir

Again, the program freezes as soon as I open the serial port.? I can only get Xastir to relaunch once I clear out the xastir.cnf file.? As soon as I try an open the port with the weather station on it, Xastir freezes.? Again, I can see the data from the serial port easily with minicom.? Xastir is just choking on it.? 

any ideas?? Day 7 without APRS now.

I have a vague memory of Debian Squeeze being stubborn about serial
port permissions as long as the user was not a member of the group
'dialout'.? As root, issue the following command to add your username
to the group, dialout.

? usermod -G dialout username

where 'username' is the username that starts Xastir.

You can see what group(s) of which your username is a member by
issuing the command below (not as root)

? id -a

The above will verify if your user is a member of 'dialout' or not.

The fact that your other methods didn't work is puzzling, though - I
know I have been able to take the insecure way out for something quick
and dirty and change the permissions of /dev/ttyX0 to '777' and see
things work.

Hope this helps.

Hello,

because i'm not a programmer it take me 4 hour to find how to code it in C.
It's verry too long for 15 lines.
So what did you think about lowercase or upper case ?
I can't make more. For the time it check a file if exist and use it or not
(alert.xbm)
