Interesting. I don't actually remember the last time I saw a system where the defined hostname wasn't qualified; must be at least a decade, and I wouldn't be surprised to find it was last millennium. I'd almost be even more surprised to find a setup like that, which also had DNS and resolver config setup so that the right FQDN came out the far end of a lookup. I wonder if that's mostly a function of the timeperiod, or if it still varies in different social environments. > These days though I don't wander far from home with my X11 setup > (unless it's the one on my laptop).

Actually, from here, I'd guess it would be; your Message-Id and the headers from your local smtp instance all agree in calling your system 'more.local', and I'd generally assume those programs just took the hostname as given. Easy enough to check; can just use `-k` to leave the temp file of m4 defs around, so you can run an invocation like `ctwm --cfgchk -k` (cfgchk serving as a convenient way to run it without trying to take over anything and exit right away), and seeing what's in the filename it gives you. > One thing I have often wondered about (well, only so often as I've had > to edit my .ctwmrc to add something for a new system, etc.) is whether > or not it might make sense to somehow expose some or all of the > environment variables to the M4 processing.... We'd have to actually do all the proper value escaping we should already be doing (but aren't of course) if we tried that ;) You might be able to do something with esyscmd() and echo or env in m4 to pull in or conditionalize on env vars... -- Matthew Fuller (MF4839) | fulle...@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
