Tips on Debugging xterm problems...

Jack C. Mahaffey — Tue, 24 Jun 2003 12:30:31 GMT

Are there any logs or tips that can be used to debug xterm problems?

I got some xterms that are no longer working and want a place to start...

Hi,

while holding down the CTRL-Key and klicking on the left mouse button you'll get a menu where you can turn logging on.
The logfile is at $HOME/XtermLog.

Regards

The log that xterm could create has nothing to do with debugging. it is a transcript of the sesison.

One way might be to actually run the xterm in another window, in the hopes of catching an error message. Another might to run it like this:

xterm > /tmp/xterm.$$.log 2>&1

so that you could get stdout and stderr for the xterm app itself.

Are you referring to the program called xterm, or do you mean you have some standalone Xterminal boxes that are not booting or running correctly? If the latter, please provide the mfr and model number as Xterminals have a lot of differences for configuration.

Bill, just talking about the program xterm. Had some issues the other day and was looking for tips to determine why I had some xterm problems.

All xterm sessions were ran from the server.

Jack,

Could you be a bit more specific about the problem you facing ?

Two weeks ago I had problems with Xterm myself found out that when you use -ls option your DISPLAY was not exported correctly cause.

1. dtterm, hpterm, and xterm do not create
entries in wtmp.

Resolution:
The xterm, hpterm and dtterm were modified
to update the /etc/wtmp file when invoked
with -ls option.

I have another post on the specific problem. The problem involved xterms that would no longer get created. The xterm program would run and show under top but would not work for the users.

The solution involved creating more /dev/ptym and /dev/pty device files to match my kernel parameters. For some reason or another only 60 device files existed while the kernel parameters were configured for 600.

A limit was apparently reached before our xterm count made it to 60.

pty problems are fairly common. There is no connection between the number of pty device files and npty, nstrpty and nstrtel. The kernel parameters limit the number of open pty device files, but if the device files do not exist, then the process aborts the same way. So, if you always use SAM to change npty (and nstrpty and nstrtel), then SAM will automatically run insf to create (recreate) the required device files. Note that pty filenames must be in alphabetic order with no missing names. Searching for the next available pty device file may stop because one of the entries is missing, yet there are several still available. See the bottom of the man page: man 7 pty
