I can ping everything else, but when I ping localhost it takes a long time and and 100% packet loss.

squid root # ping -c 1 www.google.ch
PING www.google.com (216.239.51.101): 56 octets data
64 octets from 216.239.51.101: icmp_seq=0 ttl=42 time=336.5 ms

--- www.google.com ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max = 336.5/336.5/336.5 ms

squid root # ping -c 1 localhost
PING localhost.localdomain (127.0.0.1): 56 octets data

--- localhost.localdomain ping statistics ---
1 packets transmitted, 0 packets received, 100% packet loss

The interface lo is up:

squid root # ifconfig lo
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:11 errors:0 dropped:0 overruns:0 frame:0
TX packets:11 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:924 (924.0 b) TX bytes:924 (924.0 b)

But I think I could have a problem with the routing table;

squid root # netstat -r
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.168.0 * 255.255.255.0 U 40 0 0 eth0
default 192.168.168.1 0.0.0.0 UG 40 0 0 eth0

And my firewall blocks nothing.

Can anyone help me? I use gentoo Linux.

Thanks

the only thing that comes to my mind is maybe that you dont have Loopback setup in /etc/hosts

You should have a line such as:
127.0.0.1 localhost
also try only
ping 127.0.0.1
instead of ping localhost and see what you get

Hope that helps

The same thing happens when I try to ping 127.0.0.1 and I have the line in my /etc/hosts

127.0.0.1 localhost

squid root # ping -c 1 127.0.0.1
PING 127.0.0.1 (127.0.0.1): 56 octets data

--- 127.0.0.1 ping statistics ---
1 packets transmitted, 0 packets received, 100% packet loss

what distro are you using?


can you ping the box from another machine?

i had a similar problem, i could not ping the host at all but i could ping other hosts.
it turned out that a file in /proc/sys/net/ipv4 had a 1 in it and not a zero after i changed it to a zero it worked fine!

I use Gentoo-Linux.

And after I changed the 1 in the file /proc/sys/net/ipv4/icmp_echo_ignore_all to a zero and now it works fine!

Thanks!
