Hello,

never experienced this problem before. Nothing on Google helped me.

When I run:

# Ping 127.0.0.1

Returns nothing. As if expecting an answer that never comes. Then press Ctr + C and returns:

--- 127.0.0.1 ping statistics ---
117 Transmitted packets, 0 received, 100% packet loss, time 116009ms

I use 3g modem connection configured with the command:

# pppsetup

The internet connection is normal. But without the ping localhost also can not open the settings for CUPS.

Here is my /etc/resolv.conf (if it helps in something):

google.com search
nameserver 8.8.8.8
nameserver 8.8.4.4

And here is my /etc/hosts:

# For loopbacking.
127.0.0.1 localhost
127.0.0.1 darkstar.slack.org darkstar

The response of the command "route":

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
* 255 255 255 255 10.64.64.64 UH 0 0 0 ppp0
default * 0.0.0.0 U 0 0 0 ppp0

Responses to "ifconfig lo":

Link encap:Local Loopback
LOOPBACK MTU:16436 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

I'd be very happy and grateful if someone with a good heart had a clue about what is causing this problem.

Thank you and sorry for my English.

Q: What does "ifconfig" say? Could you cut/paste the exact contents?

Q: What version of Slackware are you running?

Q: What does "iptables -L -n" say? Do you show any rules blocking ICMP (ping)?

Thanks for your interest! Very much.

I solved the problem by adding the following line to rc.local:


"ifconfig lo 127.0.0.1 netmask 255.0.0.0"

Slackware version 13.1.


Iptables:

Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination
-----------------------------------
Thanks again!

I think the problem is the fact that the script "rc.inet1" which is in /etc/rc.d, was disabled.

A big hug!
