NFS blocked by the firewall
 

Hi, Folks,

I'm having volume sharing issues with NFS on Fedora Core 6.

A volume (IE a DVD) is shared on one FC6 box and see this volume on a remote FC6 box WITHOUT A FIREWALL on the sharing box. However with the firewall enabled, I cannot access the volume remotely. I can see the volume name, just unable to access the files within it. The error logs are not reporting anything that I'm seeing.

This suggests that an ethernet port is being blocked by the firewall. How would I find out what that port is, so I can open it? Or any other ideas?

Ports 111, 2049, and 4001-4003 for TCP and UDP are opened in the iptables file, suggestes the Linux Troubleshooting Bible.

I see another thread that suggestes opening 980-990. But I'd like to get an idea what ports are actually blocked by the firewall.

Thank you!

dont know if that helps or not, but do you need the internal firewall running on your system?

i have an external firewall between my LAN (at home) and the internet, but internally i keep the firewalls disabled just to make LAN networking simpler. yes i know this is not best practice, but meh what is some one going to steal from my computers at the house, my account to here... meh let em have it.

and i scan all the time for bots and what not and do not allow my kids or wife to install software so that cuts down on a lot of mess too.

Hi, Grins,

Well, I probably don't need the firewall on this private net. I can get NFS to remotely read the DVD without it; no problem.

However, just for my education, I'd like to decypher what ports are being blocked and keeping NFS from working. Any suggestions on how I can find those ports?

Thanks for the response!
