After waking my system up from sleep mode, telnet on the local host
doesn't work for a minute or two. Here's a typical attempt, which was
run about a minute after waking the system up:
$ telnet localhost 25
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
After a minute or two sendmail works fine. This is no biggie, the only
bad consequence is that fetchmail won't fetch anything for a minute or
two; but it would be nice to know what's going on.
Since this is after waking up from sleep mode, the odds are that the
network manager stuff is still starting up...especially if this is a
wireless connection.
NetworkManager generally closes the firewall down, brings the network
up (and if it's a wireless, that includes authenticating, et al) and
then starts the firewall. While the firewall is set to not accept
connections, trying even localhost won't work.
