More building blocks of my environment:
scripts, I need some way to run them in order to do useful things. The
obvious thing to do is just to run them from the command line, but
this requires that you have a command line sitting around and in my
disposable environment this is
generally not the case.
tkssh are two very simple
TCL/TK programs that do essentially the same thing. They each throw up a
window with a label and a text entry field, let me enter text, and then
run the appropriate command with the text as the arguments when I hit
return in the text entry field. I have my window manager set to bring up
an applications menu when the middle mouse button is pressed in the root
window, and one or the other of these is the top entry on that menu.
(At home I pretty much only use
sshterm, so it is the top entry;
at work, I have enough bandwidth to use
rxterm by preference.)
If I'm opening several windows on a single machine, though, it's kind of
annoying to have to keep calling up one or the other of these programs.
So I have a third command,
pyhosts, which is designed to make it more
convenient to repeatedly open windows on random machines.
The easiest way to explain how it works is to show you that rarity on
WanderingThoughts, a picture:
The empty area just below the top is a text entry field; the
mailswitch labels are buttons. If I enter a machine name in the text
field and hit return,
pyhosts starts an
rxterm (or an
sshterm if I
flip it to do that) and adds a label button for the machine. Clicking
on the label starts another
sshterm. Using shift-return
(in the text entry field) or the middle mouse button (on the label
rxterm -r to get a root shell instead of a normal shell.
Machine labels are sorted in alphabetical order and only the most
recently used four are kept, in order to keep the size of the window
(Because I am grimly decluttered in my computer interfaces, one can
delete machine labels with the right mouse button and I routinely do so,
pyhosts window to its minimum size.)
I am not sure that this
pyhosts setup is the last word in getting
decently convenient access to a reasonably large collection of
random machines, especially given my flirtation with sshmenu and other hacks. However, I have not yet attempted to
come up with a better approach.
(My normal full desktop environment isn't a Gnome desktop, so I can't just use sshmenu et al. Some day I will figure out how to have Gnome applets and Gnome's alert area without having to run all of Gnome.)
Credit where credit is due department:
pyhosts is my adaptation of
a program that I inherited from a previous coworker (who I believe
may have inherited it from yet another coworker), because I saw it
and thought it was a nifty idea. Most of the code is not my own.
(The chainsaw marks are my work.)
Sidebar: an interface that didn't work
I have experimented with hooking things up so that if I select a
machine name (in the X selection sense) and call up a menu entry, it
automatically runs an
rxterm to that machine. This
sounds like it would be neat and convenient; you could do things like
get email mentioning problems on machine X, highlight the machine's
name in the email, pop up the menu, and bang, have a login on the
machine to poke around.
In practice, I don't seem to run into this sort of scenario often enough to make this feature worth remembering. It was faster to just retype the machine name (or select and paste it, which is a couple of mouse clicks) than it was to find and invoke the special 'fast' way.
