[gentoo-user] OT: auto rename konsole session tabs?

[gentoo-user] OT: auto rename konsole session tabs?

[James]

Hello

OT:  I use kde and quite a lot of konsole sessions for  admin of many other
systems.  I currently manually use 'rename' in kde to put the system's 
hostname into the tab (located at the bottom of the window), for quick 
reference. Is there a way (trick) to automatically do this? 

My prompt (command line) does this automatically, I just want the hostname
of the remote host(or IP address)  I ssh into to replace the 'shell #' 
that is there by default. If not ssh'd into a remote system, then the 
default 'shell #' is ok as the default.


thoughts and ideas are most welcome,

James

Not sure if you can rename them based on what you run in the session.
But you can name them when you start a session.

Click on the menu entry Settings->Configure Konsole
Choose the Session tab.

Create a new session for each remote machine

"Name" is used in the tabname, so you can enter the hostname.
"Execute" is used to start the session, if you want to start ssh directly 
enter "ssh <host>" here.

There are a few examples present you can look at.
You probably haven't used them yet, otherwise you wouldn't be asking this :)

When you want a new session you should choose the session you configured 
instead of the default session named "Shell".

Well when I ssh into a remote system, bash detects this (hostname)
and displays the hostname in the prompt(command line) 
automatically. So it is possible, another way to pose the question
is how to transfer this information 'automatically' from bash
to the kde-session-tab-name?

Yes, but if I ssh into a new system with a previoulsly unknow name or IP, 
then I have to manually change this information?  If that is true, then
it is not what I want/need. I need auto_discovery of either the hostname
or IP address of the remote target, passed to the kde-session-tab-name.
That's the challenge. It's for newly installed machines with
new names and IP. Or some remote machine, I have never ssh'd into before.
Furthermore, as the list grows very large, I it will become a pain doing this
before remote access. Many are gentoo based but other are not. I can modify
some files on the remotes, if necessary, but many will only be remotely
admin'd one or twice a year (hopefully).

Auto_magically???? maybe it's easier to auto_magically discover (pass) 
the remote's ip address to the kde-session-tab-name parameter?

I'd say that you got the remote hostname in the prompt because you are in 
effect running bash *on the remote system* and seeing its output, not 
because bash "detects" the hostname.

Probably because you haven't ticked the "Set tab title to match window
title" box.

To be fair, I'd completely forgotten about that option and would have 
qualified my statement with that information if I had remembered.

Hello Bo,

This works very good, but it's a bit long.
I prefer just the host name or  just the ip address. Using this technique
I get something like this:
"james@icelander:~/projects/manuals - Shell"

Is it way to long.

I think I'll keep searching for a way to just either the hostname
or the IP in the tab....

thanks.

James

To get only the hostname (\h is substituted with the hostname as you can read
in `man bash`) ...

# export PS1=$PS1'\[\033]0;\h\007\]'

Or for the ip you can try this evil command... ;) (it depends on
sys-apps/iproute2 and will be overridden by $PS1 -- try in another terminal if
you just typed the above command) ...

# export PROMPT_COMMAND="ip -o -4 addr show scope global | sed -r 's/.* ([12]?[0-9]?[0-9](\.[12]?[0-9]?[0-9]){3})\/.*/\x1b]0;\1\x7/'"

(If anyone knows a better way to get the ip and only the ip I'm interested...)

Anyway, what's wrong with Mike Williams' suggestion? That's works fine for me.

Well I tryied this command by puting it in the .bashrc file on both
the host system and the target remote. It did not alter the
kde-session-tab at all. Then I tried just issuing the command
from the CLI and it did nothing either. So I'm not sure
I'm trying this solution as intended.

OK, I'm going to respond to this, directly from Mike's email. I had
not gotten around to trying what he suggested, yet.

Are you absolutely certain that this option is enabled:

Settings -> Configure Konsole -> General -> 
Set tab title to match window title

? And make sure you don't make a typo...

Try it in e.g. an xterm also. You should see your hostname in the title. It 
works for me at least...

Uh, I forgot that I have created this symbolic link to allow users to execute 
ip (without giving the full path):

# ls -l /bin/ip
lrwxrwxrwx 1 root root 8  1 jun 11:28 /bin/ip -> /sbin/ip

Prepending the command by /sbin/ should work too (if sys-apps/iproute2 is 
installed).

yes, absolutely certain.

yes the hostname is work. What I could not get working is just
the ip address.

 

thanks very much Bo, the hostname is working. 
I'll live with that for now.

You can set the tab title of konsole with something like

setkonsoletabtitle () {
        echo -en "\e]30;$*\a"
}

For ssh I have another shell function:

ssh () {
        setkonsoletabtitle "$1"
        command ssh "$@"
        cd .
	# that sets the tab title back to the normal "local look" here
}

Of course this only works nicely if you use "ssh host" or "ssh
user@host" and not "ssh -l user host".

Regards...

dcop, and a wrapper around ssh, is the only way I can think of.

dcop konsole-{PID} $(dcop konsole-{PID} konsole currentSession) \
renameSession "${HOSTNAME}"

I don't however have a reliable way of figuring out the PID of the current 
konsole process.
Or, perhaps I do. http://lists.debian.org/debian-kde/2004/04/msg00271.html

This konsolescript does what you need. Logging to remote it shows on tab 
user@host , on local it shows user or programm runing.
