Hello! I'm trying to install our RedHat clients by using a custom kick-start script.. The clients are configured to use NIS for authentication and they also mount home-directories using NFS. Everything works fine as long as I use "firewall --disabled" This I dont like, I would love to set up som basic firewall security on the clients.. now.. I have tried "firewall -medium -ssh" and "firewall --high -ssh", then unfortunately everything blocks at boot: the clients are unable to mount via NFS, also they are unable to get NIS/YP-login-information (rpc). This is pretty annoying! I have tried to open the firewall for several ports that are needed/used by these services, like this: firewall --medium --ssh --port 2049:tcp,2049:udp,1110:tcp,1110:udp,1598:tcp,1598:udp, 2323:tcp,2323:udp,2363:tcp,2363:udp,111:tcp,111:udp,369:tcp,369:udp, 530:tcp,530:udp,1024:tcp,1024:udp,6000:tcp,6000:udp,752:tcp,752:udp, 22:tcp,22:udp (everything on one single line of course..) BUT STILL... the clients are UNABLE to mount using NFS and are also unable to ypbind to the NIS server.. Please please pleeeeease tell me.. what am I doing wrong ? I just can't seem to get it working... As I said: "firewall --disabled" => everything works fine! (no wonder :-) Allman
