|
|
>There might be a problem with the "netstat" program in 2.0.x-based Linux
|
|
distros. After a Linux reboot, running "netstat -M" works fine but after a
|
|
MASQed computer runs some successful ICMP traffic like ping, traceroute,
|
|
etc., you might see something like:</P
|
|
><P
|
|
>masq_info.c: Internal Error `ip_masquerade unknown type'.</P
|
|
><P
|
|
>The workaround for this is to use the "/sbin/ipfwadm -M -l" command. You
|
|
will also notice that once the listed ICMP masquerade entries timeout,
|
|
"netstat" works again.</P
