connection refused while trying to mount nfs

Question

Nothing I've googled out helped me yet including questions asked here.

While issuing :

mount -t nfs -o proto=tcp,port=2049 192.168.243.148:/home/nfs/ /mnt/nfs

I've got response

mount: mounting 192.168.243.148:/home/nfs/ on /mnt/nfs failed: Connection refused

configs I'm currently running are listed below

/etc/export :

/home/nfs/ 192.168.243.0/24(rw,sync,fsid=0,anonuid=0,no_root_squash,subtree_check) 

rpcinfo -p

I've disabled ufw. Not sure what else I can do. I'm running Ubuntu 14.04. I don't have any problem mounting nfs on machine running nfs server.

Answer 1

dont worry just run rpcinfo -p it shows some tcp and udp ports you should

allow all this ports into your system firewall and retry it will works...
