I set up syslogd again. I encountered the following problems. First the
syslogd-config script output an error "setfacl: No such file or
directory". This turns out to be from the command: setfacl -m
u:system:rwx /dev. Apparently /dev isn't a file or directory on 2003!
Next I tried starting the syslogd service and it wouldn't work. I had
this problem before when I set up syslogd on this server but since
nothing ever got written to /var/log/messages I removed it. Turns out it
has a problem creating a socket file in /dev. By default it tries to
create /dev/log and it can't. Syslogd does have a -p paramter to specify
an alternate place for this socket file. I used -p /var/run/syslogd. I
had to hack that into the registry.
As for /var/log/messages I have:
[ccadmin] sons-sc-cc:tail -f /var/log/messages
Jun 4 23:12:16 SONS-SC-CC syslogd: restart
Jun 4 23:12:29 SONS-SC-CC syslogd: exiting on signal 15
Jun 4 23:12:44 SONS-SC-CC syslogd: restart
Executing syslog hello in another window just gives me a command prompt
back. Nothing gets written to /var/log/messages!
Wait, I take that back, somewhat... While the syslog hello doesn't put
anything in /var/log/messages an rsh localhost id does:
[ccadmin] sons-sc-cc:tail -f /var/log/messages
Jun 4 23:12:16 SONS-SC-CC syslogd: restart

Another data point I figured out. Currently I can rsh localhost but I
have to supply a password. This works. "rsh localhost id" hangs. If I
add localhost to /etc/hosts.equiv or if I remove the password for the
user I am rsh'ing as, both methods of allowing passwordless login, I get
"Switching to user failed":
[ccadmin] sons-sc-cc:rsh localhost

[ccadmin] sons-sc-cc:
Putting "localhost" in ~/.rhosts does nothing - I'm still prompted for a
password.
One interesting thing is that I still do not understand how it works at
all. The inetd service is running as Local System Account. From what
I've read this Local System Account does not have enough privileges on
2003 Server to perform the operation of switching user. Yet in the first
case above it manages to do that. How?
It seems whenever I configure it so allow passwordless login (adding
localhost to /etc/hosts.equiv or removing the password from /etc/passwd)
I fail with "Switching to user failed".
The sshd_server user, created by the ssh-host-config script, should have
enough privileges to switch user so I changed inetd to start through the
sshd_server user. Now I get:
[ccadmin] sons-sc-cc:rsh localhost

What's the deal here?
