Hi,

Everthg works great under my router (internet, ssh, ftp...) but the Nfs
it's terribly slow
it 's of no way

My server 192.168.123.100 config :
===========
at the startup I mount the folder in /home
this is working greatly !!
with in rc2.d : mount IP:/mnt/hda5/home ;

================
I think I have found the problem or not ... (?)

1/I read that server/client non identical FULL / HALF duplex can be the reason ??

2/ that I have to measure my ethernet line
when i did :

ping -s 8192 192.168.123.100
(server)
i get no bytes !! nothing

ping -s 256 192.168.123.100
i get 1ms

ping -s 48 192.168.123.100
i get 0.48ms

What should I do ??

Thank you very much for you help !!

For the ping, i believe the dest. computer might not reply to large packet sizes. I've seen this happen a few times, but not consistently for every machine. Perhaps it's got to do with os settings, some kind of dos prevention maybe? Not sure.
NFS (the rpc stuff actually) uses random ports. You'll have to set them up to use static ports http://www.linuxquestions.org/questi...d.php?t=294069

Then you'll need to open the appropriate ports in the firewall. I've had this problem as well from way back, even with static ports the damn thing takes ages to mount. After mounting it works fine though. Once upon a time i got it right, and the mounting was fast. Then i had to format the machine and it went back to being slow. Most of the time though, it works if i disable the firewall, so i guess it's got something to do with that. Good luck!
