[SOLVED]Connection to localhost fails

The connection worked smoothly after boot, but after hours of uptime I suddenly was unable to connect to localhost. As a result, I cannot open MLDonkey web interface with any browser. Sonata cannot connect to MPD. SMPlayer cannot recognize its running instance so it ignores my "Only on running instance" option. This is very annoying. I typed "ifconfig lo" and got the following results:

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          LOOPBACK  MTU:16436  Metric:1
          RX packets:15625 errors:0 dropped:0 overruns:0 frame:0
          TX packets:15625 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:8925409 (8.5 Mb)  TX bytes:8925409 (8.5 Mb)

I tried restarting the network daemon, using "127.0.0.1" instead of "localhost", but cannot solve the issue. It happened several times before so I know reboot can solve it, but really not a good solution. Someone please give me a helping hand? Thanks in advance.

Re: [SOLVED]Connection to localhost fails

Is the localhost interface even up, since ifconfig will tell you about down interfaces, when you name them explicitly.

ifconfig lo up

will definitely fix the problem temporarily.

I think I solved a similar problem after merging the changes to /etc/rc.conf involving the removal of localhost stuff (which is now in another file that is never edited)

I will try this when it happens again. Thank you for the suggestion.

Re: [SOLVED]Connection to localhost fails

Check your hosts too, here I could not connect to my local postgresql db.

There should be a line with:

127.0.0.1       localhost.localdomain   localhost YOURDOMAIN

This solves my problem perfectly. Thank you so much!
