Hi, we have a problem with login to the nodes via ssh. We have some "normal" users on the head node with their home directories under /home/<username>, but most users have their home directories mounted from a different machine - lets call it nfshome with IP 130.xxx.xxx.xxx - to /Users/<username> on the headnode.
Both, the head node and the nodes itself have the following line in their /etc/fstab 130.xxx.xxx.xxx:/Volumes/XRaid00/users /Users nfs defaults 0 0 The nodes also have the line nfs_oscar:/home /home nfs rw 0 0 The nodes are able to automount the user home directories sitting directly on the head node (/home/<username>) and those users can access the nodes via ssh without passwd. However, the nodes fail to mount the nfs mounted home directories 130.xxx.xxx.xxx:/Volumes/XRaid00/users. The error in boot.log is, e.g., Jun 26 18:32:23 n01 mount: mount: mount to NFS server '130.xxx.xx.xx' failed: System Error: Connection timed out I wonder how this can work at all. The head node and the nfshome machine both have public IP's 130.xxx.xxx.xxx so it is no problem for the head node to mount the user home directories from nfshome. However, the nodes are not connected to the public net, they sit - as usual - in a subnet 192.168.100.xxx connected to the headnode. From the nodes itself it is even impossible to ping the nfshome machine which means that a mount -t nfs 130.xxx.xxx.xxx:/Volumes/XRaid00/users /Users on the nodes is not possible. Question: What is the correct setup (on head node and/or nodes) that the nodes a) mount the user home directories 30.xxx.xxx.xxx:/Volumes/XRaid00/users under /Users b) users can access the nodes via ssh (I assume if a) is fixed b) is fixed as well) Thanks for any help!
