Bzzt.  The error is on my side. I actually reversed the parameters.
" 2>&1 >/dev/null" will not make the whole thing go silent.
That's what " >/dev/null 2>&1" does.

With " 2>&1 >/dev/null", STDERR still gets printed.  So you could
simply use " >/dev/null" for the same effect.

That sounds weird.  If the output is redirected, then it should not
show up at all.  Could it be that you have added the line to several
scripts that are run at login?

Here's a snippet of information that might help you find out where to
search, written down by a friend of mine:
- 8 only the first match of these last three will be used, if 
any of
these three files are present.

if bash is an interactive *non*-Login-Shell:
/etc/bash.bashrc
afterwards:
~/.bashrc (if present)

Login-Shells are used by console-tty, ssh, other remote Logins,
sometimes sudo and su.
*non*-Login-Shells are used for the other cases (like xterm, other
X11-Terminal-Clients, and some other caseses of sudo and su).

A classic X-Login will run /etc/X11/Xsession, which in turn checks if
~/.xsession and ~/.xsessionrc are present.  If they are, .xsessionrc
will be sourced, while .xsession will be spawned as a separate process.

- 8< end snippet 8<

And if that wasn't already confusing enough, there's more to be found at
https://www.gnu.org/software/bash/manual/html_node/Bash-Startup-Files.html

Just to make things easier for others trying to debug your issue - you
have an SSH agent named keychain running on the *server*, not on the
client?

If so, I could imagine X2GoClient is getting confused by this output
when it tries to ssh into the server. Do you think you could, for
debug purposes, silence this keychain tool by running it with
" 2>&1 >/dev/null"
(without the quotes) appended to its call?

[X2Go-User] x2go login error

2015-01-19 Thread Rance Hall
My x2go server is my desktop at work and there is a .bashrc that launches
keychain and loads my ~/.ssh/id_dsa into the session environment.

the terminal gets the following output before the prompt:

 * keychain 2.7.1 ~ http://www.funtoo.org
 * Found existing ssh-agent: 1829
 * Known ssh key: /home/rhall/.ssh/id_dsa

Then you get a bash prompt.

This output becomes the text of the error message when I try to connect to
this same box via x2go-client.

The relevant lines in .bashrc are:

/usr/bin/keychain ~/.ssh/id_dsa
source ~/.keychain/rhall-sh
