[SOLVED] Server Netwrok issue (icmp, ssh)

Postby kjstephan » Sep 11th, '12, 14:09

Hi @all,

i've setup mageia on an virtual machine trying to use it as a server.

Now i cant ping or access the server. The server itself has networking support and can ping the world.
i turned of shorewall and iptables -L shows only access accept all. When i run tcpdump icmp on the server i can see the ping request from outside but the server itself does not respond.

The option echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_all is set. /etc/sysctl.conf shows nothing wich should cause the trouble.

Strange thing too, i have a ping reply during startup for some seconds. Then it is silent again. The ping works between startup and login prompt.

Hope for some help

Jörg

it seems really a firewall problem...
how have you turned off shorewall, via mcc or with some other command?

have you tried to turn off iptables too?
Code: Select all
systemctl stop iptable.service


this is to definitely disable the daemon:
Code: Select all
systemctl disable iptable.service

glad you have solved in some way :)

probably the answer is in this old bug report:

https://qa.mandriva.com/show_bug.cgi?id=34132

stopping shorewall put DROP for all chains


You have to stop "iptables" to have everything open.
