rup:: RPC: Program not registered in RHEL6.1

I just installed Redhat Enterprise Linux 6.1 on one HP server. Following error met when rup it on other servers:

$rup coolnjmcl033 rup:coolnjmcl033: RPC: Program not registered
SOLUTION:

1)check if all nfs related services are working:

[root@coolnjmcl033init.d]# rpcinfo -p program vers proto port service 100000 4 tcp 111 portmapper 100000 3 tcp 111 portmapper 100000 2 tcp 111 portmapper 100000 4 udp 111 portmapper 100000 3 udp 111 portmapper 100000 2 udp 111 portmapper 100011 1 udp 875 rquotad 100011 2 udp 875 rquotad 100011 1 tcp 875 rquotad 100011 2 tcp 875 rquotad 100003 2 tcp 2049 nfs 100003 3 tcp 2049 nfs 100003 4 tcp 2049 nfs 100227 2 tcp 2049 nfs_acl 100227 3 tcp 2049 nfs_acl 100003 2 udp 2049 nfs 100003 3 udp 2049 nfs 100003 4 udp 2049 nfs 100227 2 udp 2049 nfs_acl 100227 3 udp 2049 nfs_acl 100005 1 udp 51310 mountd 100005 1 tcp 60605 mountd 100005 2 udp 42799 mountd 100005 2 tcp 44201 mountd 100005 3 udp 49544 mountd 100005 3 tcp 49098 mountd 100024 1 udp 37035 status 100024 1 tcp 60898 status 100001 3 udp 1008 rstatd 100001 2 udp 1008 rstatd 100001 1 udp 1008 rstatd

If there is no runningrstatdservice , start it by service rstatd start.

Accordingto RHEL 6 RUP manual:

rup: RPC: Program not registered

Therpc.rstatd(8)daemon has not been started on the remote host.

2) check if package rusers-server-*and rusers-* are installed: rpm –qa|greprusers. If not, install it and then restart service rstatd.

PS:

Other userful commands:

1. rup localhost
2. service rstatd status

According to New Featuresin RHEL6,

1.ext4 file system is introduced.
2. xen isremoved and kernelvirtualizationmachine(KVM) is introduced.
3. neatcommandis removed.
4. portmap service is removed.
5. iscsi is introduced, whichsupportsforSAN.
6. rpmbuild is available, which is used to create our own rpms.
7. File encyption is added.
8. palimpsest is available fordiskmanagement.
9.Virtualmachine willrunonly on 64bit processors.
10. postfix service isrecommendedinsteadof sendmail service.

Accordingto Chapter12.Network File System (NFS),

Theportmapservice wasused to map RPC program numbers to IP address port number combinations inearlier versions of Red Hat Enterprise Linux. This service is now replaced byrpcbindinRed Hat Enterprise Linux 6 to enable IPv6 support. For more information aboutthis change, refer to the following links:

• TI-RPC / rpcbind support:http://nfsv4.bullopensource.org/doc/tirpc_rpcbind.php
• IPv6 support in NFS:http://nfsv4.bullopensource.org/doc/nfs_ipv6.php

Required Services

nfs

service nfs startstarts the NFS server and the appropriate RPC processes to service requests for shared NFS file systems.

nfslock

service nfslock startactivates a mandatory service that starts the appropriate RPC processes which allow NFS clients to lock files on the server.

rpcbind

rpcbindaccepts port reservations from local RPC services. These ports are then made available (or advertised) so the corresponding remote RPC services can access them. rpcbindresponds to requests for RPC services and sets up connections to the requested RPC service. This is not used with NFSv4.

The following RPC processes facilitate NFS services:

rpc.mountd

This process receives mount requests from NFS clients and verifies that the requested file system is currently exported. This process is started automatically by the nfsservice and does not require user configuration.

rpc.nfsd

rpc.nfsdallows explicit NFS versions and protocols the server advertises to be defined. It works with the Linux kernel to meet the dynamic demands of NFS clients, such as providing server threads each time an NFS client connects. This process corresponds to the nfsservice.

lockd

lockdis a kernel thread which runs on both clients and servers. It implements the Network Lock Manager(NLM) protocol, which allows NFSv2 and NFSv3 clients to lock files on the server. It is started automatically whenever the NFS server is run and whenever an NFS filesystem is mounted.

rpc.statd

This process implements the Network Status Monitor(NSM) RPC protocol, which notifies NFS clients when an NFS server is restarted without being gracefully brought down. rpc.statdis started automatically by the nfslockservice, and does not require user configuration. This is not used with NFSv4.

rpc.rquotad

This process provides user quota information for remote users. rpc.rquotadis started automatically by the nfsservice and does not require user configuration.

rpc.idmapd

rpc.idmapdprovides NFSv4 client and server upcalls, which map between on-the-wire NFSv4 names (which are strings in the form of user@domain) and local UIDs and GIDs. For idmapdto function with NFSv4, the /etc/idmapd.confmust be configured. This service is required for use with NFSv4, although not when all hosts share the same DNS domain name.
