local network traffic (nfs) getting routed through internet?

karsten · 2006-09-28 03:03:50

i have a nfs drive set up on my server which i access from my laptop. well i copy a large file over to it and i only get about 50KB/s, which is my internet download speed. i have the sneaking suspicion it's going out to the internet first.. how can i test this and/or fix it? both computers are set up with static addresses on their own, do i have to disable DHCP on the router as well, or is it ok to leave that enabled for other machines in the house?

or, how do you set up NFS with dynamic IP addresses? thanks..

ok, I have no idea on how to solve your problem and maybe I'm totally wrong here, so it's just a thought: what is your upload speed? If the file's going through the internet the download speed can't be higher than your upload speed, maybe this could help to check it, if your on an asynchronous internet connection of course ....

do i have to disable DHCP on the router as well

I don't know if you "have" to, but, I do. Then I assign addresses to all the boxes in my network.

how do you set up NFS with dynamic IP addresses?

Use the hostname (in /etc/rc.conf) for your box instead of an address.

I have no idea re: the issue of speed of transfer.

Use

traceroute hostname or
traceroute ip-address

to check how if the connection stays local or not.
If you're doing it from the laptop , put in the ip-address of the nfs server.

Another possibility : a slow wireless connection between the laptop and your router.

ok thanks for the help guys, really appreciate it. i've checked that there is just one hop between the client and server with
traceroute, and used both ifconfig and nfsstat to see if there were excessive packet errors going on, which there doesn't appear to be. what else could be causing the slowness? and yes bluepoet, upload speed is only ~11-14k so that would have ruled that out

maybe i need to test with a wired connection between the two systems and rule out the wireless issue.

edit -- i just ran a ping from the server to the client... does this look suspicious at all?

Maybe a foobar cable somewhere? These pingtimes look awefully high for a very small local network.

Just for reference, when I ping another computer, I get this:

[glenn@polaris ~]$ ping 192.168.0.254
