Greetings!
Iam a newbie in using linux and i am trying to share a linux directory to our Sun machines running on SunOS 5.6 via NFS. I have installed RedHat linux 7.1 (kernel 2.4.2-2) (seawolf) on an AMD K6 233 Mhz machine with a 30Gb Harddrive.
I have followed the instructions on the how-to's for nfs. I was able to share the directories that i need to share. I was able to read and write files to the remote directories from our Sun machines. The problem occurs in one of our application running at the Sun Workstations. It cannot access certain files because the lock service on the linux machine is not responding (that is what the log says). Does this mean that i have a problem with the lock service on the linux machine? How can i check if the lock service is working or configured properly.
Here's the portmap listing from the linux machine
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100024 1 udp 1025 status
100024 1 tcp 1025 status
100007 2 udp 745 ypbind
100007 1 udp 745 ypbind
100007 2 tcp 748 ypbind
100007 1 tcp 748 ypbind
100011 1 udp 833 rquotad
100011 2 udp 833 rquotad
100005 1 udp 1026 mountd
100005 1 tcp 1025 mountd
100005 2 udp 1026 mountd
100005 2 tcp 1025 mountd
100005 3 udp 1026 mountd
100005 3 tcp 1025 mountd
100003 2 udp 2049 nfs
100003 3 udp 2049 nfs
100021 1 udp 1027 nlockmgr
100021 3 udp 1027 nlockmgr
100021 4 udp 1027 nlockmgr
100001 3 udp 866 rstatd
100001 2 udp 866 rstatd
100001 1 udp 866 rstatd
I have read from the NFS how-to that Sun machines usually defaults to TCP while Linux Defaults to UDP protocol. Do i need to add nlockmgr with TCP protocol for it to work properly? If so, how can i configure nlockmgr to run at both udp and tcp protocols?
Your help is greatly appreciated!
I'm sorry if i asked a lot of questions.
I'm new to linux and i am still trying to get the hang of it.
thank you for your time.
