connections to localhost

[Richard Nyberg]

Sorry if my description is somewhat vague, but here it is.

After some uptime I can no longer send mail. 

[murmeldjur//rnyberg]$ ps axlwww | grep sendmail
    0  4438     1   9 169   0  3052 2420 select SLs   ??    0:00.02 /usr/sbin/sendmail -L sm-mta -bd -q30m -ODaemonPortOptions=Addr=localhost
   25  4445     1   0 168   0  2932 2320 pause  ILs   ??    0:00.01 /usr/sbin/sendmail -L sm-msp-queue -Ac -q30m
  502  4596  4565  10 169   0  1000  280 -      RL+   p0    0:00.00 grep sendmail

[murmeldjur//rnyberg]$ netstat -a | grep smtp
  0 tcp4       0      0 localhost.smtp        *.*                   LISTEN

[murmeldjur//rnyberg]$ telnet localhost smtp     
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Operation timed out

It's strange that stopping and starting sendmail don't help,
but rebooting does.

I also get problem with sshd and X forwarding. Setting the option
X11UseLocalhost no, makes it work.

I don't know when this behaviour started but it's been so for a while.
