I poked around at the source last night for a while. I wish I were a C
programmer, but I'm not.
Turns out that 'w' uses the utmp file. Also turns out that sshd makes a
utmp entry just fine (see lib/sshsession/wtmp.c). So the theory put forth
by one of our sysadmins that sshd wasn't making a wtmp/wtmpx/utmp entry
isn't the case.
Strangely, this "undocumented feature" doesn't appear on my development
machine (Solaris 2.6 / SPARC-2), only on my production servers (Solaris
2.6 / SPARC-5s and SPARC-2s). On the dev machine, even users sitting idle
in their shells (normal users have PERL menus instead of real shells) show
up in 'w'. Which means that there's a difference in utmp process
accounting between my dev box and the live box, and this difference
doesn't appear to be in the ssh source at all.
The utmp.h files are identical on the two machines, and both are using the
vendor-supplied libc.so.1
Any other ideas where I could look to find the cause of this problem would
be much appreciated! A list of libraries and header files involved in utmp
entries, even, would be a good place to start.
