rpcinfo: couldn't find a suitable transport

  • 772

After setting up NFS on a server, rpcinfo -p servername from a client is returning the error message

rpcinfo: couldn't find a suitable transport

Connectivity is fine, checked with tcpdump. On the server hosts.allow contains the necessary entries. /etc/netconfig contains the following

# This config file is part of some non-installed packages (like nfs-utils)

# In case you install a tool that requires this file, please comment out the following lines:

unix       tpi_cots_ord  -     loopback  -      -       -

Any ideas?

  1. The problem, believe it or not, was caused by the blank line after the main comment block in the file /etc/netconfig. After removing the blank line, the mount worked.
