Core 4 Test 1 cannot nfs or autofs to other machines

[prestonjb]

while I am able to set up core 4 test 1 as an NFS server... When I try to connect to an NIS/autofs/nfs HPUX server or to a Redhat 7.2 plain nfs server I get the following error:

mount to NFS server 'SERVERNAME' failed: server is down.

I've tried the nfsvers= option with no luck. Odly the issue is not the case if I try to mount from Redhat 7.2 to an export on Core 4 T1. That works as expected.

The NIS stuff works too as I see the autfs /home and other dirs but when I try to cd into them I get errors which I traced to nfs failing on the client (C4T1 side)...

I wonder if I turned on some fire wall feature (I thought I chose NO FIREWALL during setup... However I don't really know how to controll the FW to see if it is setup (or off as I want it)... But the fact that I can connect to a drive from the outside to C4T1 seems like the FW should be off/OK.

I have done some testing today and I am having troubles with the latest FC4 kernel release to export through nfs . The RPC portmapper is not able to connect from FC3 to FC4 or vv it is unable to find a route however the network is OK. I can connect to a Linksys NSU from both FC3 or FC4. with all kernel releases The kernel version xxx.1177 seem to cope with it better. I will try to do some more testing. I have been unable to get info from the fedora test list.

I can export NFS just fine on FC4 the problem is I cannot "import"...

I was trying to autofs an /home dir from another machine (HPUX) and I get "server not found"... However exporting works just fine.

I also noted that Xwindows cannot import other client displays nor does rlogin work as expected.

This almost seems like a port mapping problem... However it is wierd that exports work while mount (importing) does not.

Is no one else having a problem with nfs (mounting a drive from another machine)

??????

you may be having a difference of protocols, for example if FC4 nfs is exported over tcp AND udp but the older nfs export is
being exported over udp only you may have to tell the FC4 to mount using udp.

somewhat cryptic repspnse, I know. sorry

Bulvad: Thanks. Yea I knew about the flag but for some reason thought that can't be it... Well turns out it was...

And the change to udp goes in the /etc/sysconfig/autofs file

Change the LOCALOPTIONS=""
to LOCALOPTIONS="udp"

and restart autofs and everything works!!!

Thanks for the push!
