how to manipulate iptables in RHEL3 using ssh

dsids · 06-22-2006, 08:59 AM

Hi Everybody,
I just installed RHEL3 on one of my machines in my house..Although Im able to access my RHEL3 machine using ssh, and then starting httpd but because of the iptables Im not able to access httpd through the web browser..
Can anyone help me out to access the iptables configuration in RHEL3 where I can mention : allow httpd inside the LAN...

Thanks
Danish

you need to allow port 80 for atleast your lan. The Rhel has weird looking rules. Personally i would just do the following

Code:

localhost=x.x.x.x
lan=x.x.x.x/x.x.x.x
/sbin/iptables -A INPUT -p tcp -s $localhost -d $lan --dport 80 -j ACCEPT

and then re-run the firewall script.

Its not working...My webserver is running on port 8080

# iptables -L Chain INPUT (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- anywhere anywhere
ACCEPT tcp -- localhost.localdomain codecindia.com tcp dpt:webcache

Chain FORWARD (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- anywhere anywhere

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

Chain RH-Firewall-1-INPUT (2 references)
target prot opt source destination
ACCEPT all -- anywhere anywhere
ACCEPT icmp -- anywhere anywhere icmp any
ACCEPT ipv6-crypt-- anywhere anywhere
ACCEPT ipv6-auth-- anywhere anywhere
ACCEPT all -- anywhere anywhere state RELATED,ESTABL ISHED

then open the --dport 8080. just the same as opening dport 80.
