I suddenly can't resolve localhost. I found this when I tried
fetching my mail with fetchmail. It gave me this error message.
$ fetchmail --keep
fetchmail: SMTP connect to localhost failed
fetchmail: SMTP transaction error while fetching mail from ...
fetchmail: Query status=10
The only other problem I've had is that cvsup can't find its own ip
address:
# cvsup /etc/cvsupfile
Cannot get IP address of my own host -- is its hostname correct?
I've solved this in the past by dorking around with /etc/hosts but
it's never messed up fetchmail before. Now cvsup and fetchmail are
both hosed, and I can't get them to work again. Any suggestions?
Following Lehey's advice in CFBSD (p 557)
$ telnet localhost smtp
localhost: Unknown host
or more simply:
$ telnet localhost
localhost: Host name lookup failure
Telnetting to localhost or to the smtp listener does work if I use
127.0.0.1.
Now I was mucking around trying to set up a caching nameserver (also
following procedure in CFBSD). I've obviously changed my
configuration somehow. I've put everything back the way it was before
I started having this problem--or so I think. I think these are all
the relevant files. Can anyone think of another configuration file
I've forgotten? This is a standalone (3.4R) machine connecting by
modem to my ISP.
$ more /etc/hosts
127.0.0.1 localhost #there is a tab here. Is this tab sensitive?
#just tried it without --doesn't seem to be
