freebsd cable disconnected problem

[Diogo Della]

Yes, the localhost go to this IP.

This machine has 3 NIC with 3 different IP address. If the onboard sis0 is not connected, ssh or ftp 127.0.0.1 does not work.

Other machines has the same problem, but a llitle different. In other FreeBSD, if a make any modifications like include a default gateway on the routing table, it does not work.

Is there any security issue or something like?

Thanks.

Does localhost actually go to IP 127.0.0.1?
Do you have a localhost route, check "netstat -nr"...?

You can also take a look at what your daemons are binding to via:
"netstat -anp TCP | grep LISTEN".  Are they binding to *.port or  
otherwise?
