Terminal Window Never Shows Up

[Mike T.]

Binary package hint: sshmenu

I have recently upgraded through apt-get to the latest Hardy release and found out that sshmenu 3.14-2 (installed from the Ubuntu repos) doesn't seem to work properly.

Steps to reproduce:
- Install sshmenu 3.14-2 from the repos via Synaptic or apt-get
- Add a Host to the sshmenu applet with the following config
Title: domain.com
Hostname (etc): <email address hidden>

- Save the new host and then click the option you just created from sshmenu. Your terminal window will never show up.

P.S. I know ssh is installed and working properly as I can open a Terminal window manually and run the following command just fine:
ssh <email address hidden>

I'm the developer of SSHMenu - here's my response to a similar report on SourceForge:

I don't have access to a system with the latest gnome-terminal, so remote debugging is the order of the day :-)

Ultimately, all SSHMenu does is call gnome-terminal with a list of arguments. I'm guessing that the gnome-terminal segfault will be reproducible if we can directly invoke gnome-terminal with the same arguments - and thus take SSHMenu out of the equation.

Looking at the commit history for gnome-terminal, it looks like command-line option handling was ported from popt to Goption in January and this may be relevant.

It's also possible that gnome-terminal's valid options have changed and SSHMenu will need to be tweaked to generate command lines compatible with the new version.

If a host is defined in SSHMenu with these parameters ...

Title: Local Host
Hostname: localhost
Geometry:
Profile: <None>

... then this is the command which will be run:

gnome-terminal --title="Local Host" -e "sh -c \"ssh localhost\""

If the geometry is set to the top right corner then this command will be run:

gnome-terminal --geometry=80x24-0+25 --title="Local Host" -e "sh -c \"ssh localhost\""

If the "Big Font" profile is selected, then this command will be run:

gnome-terminal --geometry=80x24-0+25 --window-with-profile="Big Font" --title="Local Host" -e "sh -c \"ssh localhost\""

If a non-Unicode Polish locale is selected by setting:

Hostname: LC_ALL="pl_PL.iso-8859-2" localhost

Then this command will be run:

LC_ALL="pl_PL.iso-8859-2" gnome-terminal --disable-factory --geometry=80x24-0+25 --window-with-profile="Big Font" --title="Local Host" -e "sh -c \"ssh localhost\""

Can you please try these commands and see if any of them cause the same segfault?

The latest version of sshmenu.rb in subversion accepts a '-d' option which enables debugging output to STDOUT. I use it by invoking the standalone (non-applet) version of SSHMenu like this:

  sshmenu-gnome -d

The latest version of this library is here:

https://sshmenu.svn.sourceforge.net/svnroot/sshmenu/modules/sshmenu/trunk/lib/sshmenu.rb

Let me know how you get on.

The original submitter reported via email that this command-line failed when running
gnome-terminal directly:

  gnome-terminal --title="Local Host" -e "sh -c \"ssh localhost\""

I passed the report on to the gnome-terminal maintainers who responded
immediately with this patch:

  http://svn.gnome.org/viewvc/gnome-terminal?view=revision&revision=2373

It should fix the gnome-terminal segfault,but we'll have to wait and see
whether SSHMenu works with the new gnome-terminal.

[Mike T. (mike-webco)]

Thanks for the response Grant. Here is the result of running the gnome-terminal command directly. My guess is that the next gnome-terminal update will fix this problem.

michael@michael-laptop:~$ gnome-terminal --geometry=80x24-0+25 --title="Local Host" -e "sh -c \"ssh localhost\""
