For example a command to open up a new Konsole, and open up a new tab for each
server and make a ssh connection to that server and name that tab with the
server's name. One tab per ssh connection/server
I've googled around and seen several scripts for opening a bunch of tabs, and
even naming the tabs, but none of them do that AND make a ssh connection
inside the tab.
Does anyone know how to do this?
JW,
You *might* want to look at https://computing.llnl.gov/linux/pdsh.html
You can run an interactive "Do this on many hosts at once" prompted
session, but it's all in one terminal. Using the 'fanout=1' option each
command is dispatched sequentially to each host, otherwise the dispatch
is in parallel and you can end up with tagged, but intermixed output
lines). There are plenty of other multiplexed command dispatching
programs, some, which i believe open terminals for each connection.
(e.g. conman clusterssh distribulator dsh gsh mass mussh tentakel...)
I'm including some scripts i'm working on that are, as yet, rather
simplistic and imcomplete, but which might be of value to you.
'konssh' is supposed to (at some point) be able to activate a new
konsole window and/or session tab that 'ssh's' to a host with optional
arguments.
I create a konsole session type that binds to this script, so i can pull
up a "New Konssh" that uses kdialog to prompt for the arguments after
the new tab opens. It can also be called from the command line (in a
konsole "shell" tab or an xterm or mini-cli...)
There's currently minimal support for starting a new konsole (one
session tab only)
I'm working out the means to hunt down and find a konsole window and/or
tab based upon a search criteria. that's in the 'koninfo' script. (data
collection on konsole info only at this point).
What i want to be able to ultimately do at some point, is be able to
reattach to a konsole tab by searching a konsole Caption and Tab name
and have the KDE window manager change desktops and application focus
and Konsole session tab "active" state to the match. I'm not quite
there yet ;)
Unfortunately, i'm afraid that 'dcop' may be obsoleted in KDE4 and i'd
have to re-do this in 'dbus'. 'dbus' looks infinitely more contorted
(well, much more verbose and difficult to access)

----------------------------
Look at using '--script'. that gives the ability to make dcop calls to a running
konsole to do things like feed input to a konsole tab you created with newSession
# konsole --title "titleDPG" -T "TDPG" --name nameDPG --caption captionDPG
# nameDPG becomes a dcop referencable target, captionDPG replaces "Konsole <N>"
# in the titlebar (yay!)
#dcop konsole-8992.konsole-mainwindow#1.setCaption(Qstring)
# sets only the session caption, and not permanently, apparently :-(
kde-config --path data
/home/sdowdy/.kde/share/apps/:/usr/share/apps/
check $kde_data_path/konsole for a .desktop file we can call
for "konssh.desktop" in a
dcop ${KID} konsole newSession konssh
