Do you have nisdomain set in /etc/rc.conf?

Is nis_client_enable and / or nis_server_enable set to YES in
/etc/rc.conf ?

Ciao,

Yes on both counts:

nisdomainname="wsi"
nis_client_enable="YES"

The configuration is the same as on our boxes still running
3.2-RELEASE, where everything works fine.

I confirmed that the problem also happens in my environment,
and the attached patch fixed it in my environment.  Could you
please try this patch, and try ftp or telnet again after
rebuilded and reinstalled src/lib/libc?

That probably needs to be merged to RELENG_4.  Then this PR can be
closed.  Do you agree?

Ciao,
Sheldon.

Yes of course, and it seems to be already merged to RELENG_4.

I think so (though I haven't ever written one, and don't know
exact rule for it).

Have anyone already started writing one? If not, may I try
one?

I haven't and you're welcome to.  Run it by me if you like.

Ciao,
