Package: postfix
Version: 2.8.3-1
Severity: important
I've not changed the configuration of postfix for several years, and it's been
running quite happily all that time. I've suddenly started getting the
following errors:
> Jun 25 21:35:52 mrlinux postfix/smtp[1408]: fatal: unknown service: smtp/tcp
> Jun 25 21:44:03 mrlinux postfix/smtp[1958]: fatal: unknown service: smtp/tcp
> Jun 25 21:44:03 mrlinux postfix/smtp[1959]: fatal: unknown service: smtp/tcp
> Jun 25 21:44:03 mrlinux postfix/smtp[1960]: fatal: unknown service: smtp/tcp
My smtp is set to run chrooted, and has done so, as I say, for several years.
The most common cause of this message is apparently a missing or unreadable
/etc/services file (aka the /var/spool/postfix/etc/service file). I have this
file, and it's permissions are 644, so should be readable.
FWIW, I guess the most notable difference from the norm is probably that I
have nss-ldap in use.
Any ideas?
