I've succeedig in getting a bit further ... by the time I got to the bottom of my original, I started to think in terms of rpc more, and had overlooked lookign at thte rpcbind man page, which *does* have a -h option ... setting that fixes things perfectly *almost* ...

The last issue I seem to be hitting *might* be a 6.x NFS client against a 7.x server issue ... ?

Postfix generates:

postfix/showq[65261]: fatal: select lock: Permission denied

The only post I found about this was:

http://lists.freebsd.org/pipermail/freebsd-questions/2010-April/215284.html

But there didn't appear to be any responses ... so either all responses were private to Robert, or ... ?

This is my last 6.x box, so it is not overly critical, but would be nice if I could get it to work properly ...

I just setup an nfs mount between two servers ...

ServerA, nfsd on 192.168.1.8
ServerB, nfs client on 192.168.1.7

I have a jail, ServerC, running on 192.168.1.7 ... most operations appear to work, but it looks like 'special files' of a sort aren't working, for when I try and startup Apache, I get:

[Fri Apr 01 19:42:02 2011] [emerg] (65)No route to host: couldn't grab the accept mutex

When I try and do a 'newaliases', I get:

# newaliases
postalias: fatal: lock /etc/aliases.db: No route to host

Yet, for instance, both MySQL and PostgreSQL are running without any issues ...

So, the mount is there, it is readable, it is working ... I can ssh into the jail, I can create files, etc ...

I do have rpc.lockd and rpc.statd running on both client / server sides ...

I'm not seeing anything in eithr the man page for mount_nfs *or* nfsd that might account / corect for something like this, but since I'm not sure what "this" is exactly, not sure exactl what I should be looking for :(

Note that this behaviour happens at the *physical* server level as well, having tested with using postalias to generate the same 'lock' issue above ...

Now, I do have mountd/nfsd started iwth the -h to bind them to 192.168.1.8 ... *but*, the servers themselves, although on same switch do have different default gateways ... I'm not seeing anything within the man page for, say, rpc.statd/rpc.lockd that allows me to bind it to the 192.168.1.0/24 IP, so is it binding to my public IP instead of my private? So nfsd / mount_nfs can talk find, as they go thorugh 192.168.1.0/24 as desired, but rpc.statd/rpc.lockd are the public IPs and not able to talk to each other?

Thx ...
