Ports below 1024

peo66 · 06-13-2003, 09:00 PM

Hi all,

I trying to move my webserver to a Linux platform. When i run the server on port e.g. 8080 I can connect to it from other computers. but when I use a port below 1024 i can't connect to the linux computer. The same goes for ssh which i had to moved from 22 to 2222 to make it work. Below 1024 both the sshd and httpd starts nicely and i can connect to the on localhost. but not remote.

I'm only using iptables (not ipchains) that accepts all.

What am I missing?

TIA

/Peter

Services that run on ports lower than 1024 have to be started as root.

This is not the problem, I start the services as root and they do start, e.g. netstat shows that sshd i listening on port 22. And i can connect to the service from the loccalhots. But _not_ from antoher computer in the network.

Check firewall.

I've removed ipchains
Installed latest iptables
show on iptables displays ACCEPT on all categories.
The linux i a clean Redhat 7.1 server installation.
I'dont think there is any other firewall programs running!?
How do i check that?, this is my first Linus installation:-)

TIA /Peter
