Hi all, I'm trying to configure my firewall in order to be able to mount a remote NFS exported directory.
AFAIK I must open port 111 tcp/udp (portmat). rpcinfo confirms it: # rpcinfo -p program vers proto port 100000 2 tcp 111 portmapper 100000 2 udp 111 portmapper Well, so I set next rule in my firewall: -A INPUT -d 193.146.196.198 -i eth0 -p tcp -m tcp --dport 111 -j ACCEPT -A INPUT -d 193.146.196.198 -i eth0 -p tcp -m tcp --dport 111 -j LOG --log-prefix "NFS (tcp) Input: " --log-level 7 -A INPUT -d 193.146.196.198 -i eth0 -p udp -m udp --dport 111 -j LOG --log-prefix "NFS (udp) Input: " --log-level 7 -A INPUT -d 193.146.196.198 -i eth0 -p udp -m udp --dport 111 -j ACCEPT And restart my firewall. (I use same rules for other ports, ssh, smtp...) Well, I'm no able to mount the directory, and I see this in logs: UDP privileged ports DROP:IN=eth0 OUT= MAC=00:11:11:20:6e:81:00:16:35:0a:a8:b6:08:00 SRC=193.146.196.234 DST=193.146.196.198 LEN=56 TOS=0x00 PREC=0x00 TTL=64 ID=57 DF PROTO=UDP SPT=111 DPT=822 LEN=36 and this logs comes from next rule: -A INPUT -d 193.146.196.198 -i eth0 -p udp -m udp --dport 0:1023 -j LOG --log-prefix "UDP privileged ports DROP:" --log-level 7 -A INPUT -d 193.146.196.198 -i eth0 -p udp -m udp --dport 0:1023 -j REJECT which is at bottom of all rules... I don't understand what happen, cause I can telnet to port 111 and get response. And I hace portmat in that port: #netstat -putan |grep 111 tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 10028/portmap udp 0 0 0.0.0.0:111 0.0.0.0:* 10028/portmap I do the mount: lx-arnau ~ # mount -t nfs hostname:/export/media /mnt/musica/ mount: RPC: Program not registered Got the error... but: lx-arnau ~ # netstat -putan |grep 111 tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 10028/portmap tcp 0 0 my_IP:60394 nfs_server:111 TIME_WAIT - udp 0 0 0.0.0.0:111 0.0.0.0:* 10028/portmap ... If I disable firewall, I can mount with no problem... what am I missing?¿ Thanks in advance. -- Arnau Bria http://blog.emergetux.net "Flanders, de nada sirve rezar: yo mismo acabo de hacerlo y los dos no vamos a ganar" ~Homer J.
