Sorry I don't follow.

I executed all commands on console of the same machine.

This is your inetd.conf line

poppassd stream tcp nowait root /usr/sbin/tcpd /usr/sbin/poppassd

then this is what inetd is complaining about...

[/quote]

So "inetd" can't execute what it's been told to run, I was asking if you can run them from the command line.

Do you have a "/usr/sbin/poppassd" or "/usr/sbin/tcpd"?

That "<off>/stream" looks very wrong.

Re-performed following steps to further confirm;

$ cat /etc/inetd.conf

ls: /usr/sbin/poppassd: No such file or directory

$ ls -al /usr/sbin | grep poppassd
No printout

The file /usr/sbin/poppassd seems missing.

Edit:

Further discovery;

$ apt-cache policy poppassd

poppassd:
  Installed: (none)
  Candidate: 1.8.5-3.1ubuntu1
  Version table:
     1.8.5-3.1ubuntu1 0
        500 http://us.archive.ubuntu.com feisty/universe Packages
        100 /var/lib/dpkg/status

$ apt-cache policy openbsd-inetd

openbsd-inetd:

  Version table:
     0.20050402-3 0
        500 http://us.archive.ubuntu.com feisty/main Packages

They are not installed.

I have no idea when poppassd was removed. Previously I manually installed it on repo.

Shall I reinstall these packages? How about those old files? Any action to be taken?

TIA
