Hi,
I have a problem with rpc.statd. We run our linux machines as diskless clients,
they mount their root fs via nfs from a server. For security reasons i would
like to export the root fs readonly. However, rpc.statd will not run. It exits
without an error message, but reports
Sep 26 15:33:48 rpc.statd[680]: Version 1.0 Starting
Sep 26 15:33:53 rpc.statd[681]: unable to register (statd, 1, udp).
via syslog.
I did an strace of the whole thing but am unable to locate the error. I append
it to this message, maybe someone can help (I am not familiar with network
programming).
