I can surf the web and also ping outside. I don't have much knowledge
about networking stuff so I guess I'll show you my routing script which
I got from
http://www.yolinux.com/TUTORIALS/LinuxTutorialNetworkGateway.html. It is
working so I use it. Here it is:
#!/bin/sh
iptables --flush # - Flush
all the rules in filter and nat tables
iptables --table nat --flush
iptables --delete-chain # -
Delete all chains that are not in default filter and nat table
iptables --table nat --delete-chain
# Set up IP FORWARDing and Masquerading
iptables --table nat --append POSTROUTING --out-interface ppp0 -j MASQUERADE
iptables --append FORWARD --in-interface eth0 -j ACCEPT # -
Assuming one NIC to local LAN
echo 1 > /proc/sys/net/ipv4/ip_forward # -
Enables packet forwarding by kernel
I actually use the rhn applet and it just shows the circle with grey
background colour and a white question mark on top of it. Clicking on it
gives the error message "Network Error 111: Connection refused".
I tried using up2date from console window, and here is the output:
[root@compaq alimin]# up2date

I also tried reregistering the system using update --register, but it
failed when sending my information to RHN server.
