problem sending file through nfs

james gould — Wed, 16 Jan 2002 18:15:47 GMT

User is having problems when they send
a file aroung 120meg from Unix server to
NT workstation. The file shows up as corrupted
on the NT workstation. When they send a file
around 6 meg in size there is no problem.

The users are connecting using pcnfs and
copying the data down from unix to NT
workstation. Any suggestions??

There are a couple of ways to approach this problem. The fact that a 6 mb file arrives intact and a 120mb file doesn't is bothersome. Does this happen _every time_?

You didn't mention which version of HPUX or NT you're using. This can make a difference. Make sure that you have the latest patches on both sides of the connection.

You might want to try the CIFS client instead of NFS. My experience with Windows NFS have always been heart breaking. The CIFS client may be more stable for you: that is if ANYTHING from M$ can be considered "stable".

Check the duplex/speed setting on the workstation, switch and server. Dollars to donuts, they are NOT locked to 100FD autonegotiate off.

This is an all to common problem.

Do a lanscan to see what card your looking at.
# lanscan
Hardware Station Crd Hardware Net-Interface NM MAC HP DLPI Mjr
Path Address In# State NameUnit State ID Type Support Num
10/0/12/0 0x001083CF4526 0 UP lan0 UP 4 ETHER Yes 75
#

Vi the /etc/rc.config.d/hpbase100conf or hppci100conf or whatever file it happens to be based on your system and set them to 100FD.

HP_BASE100_INTERFACE_NAME[0]=lan0
HP_BASE100_STATION_ADDRESS[0]=
HP_BASE100_SPEED[0]=100FD

Verifiy the switch is set to 100 FD autonegotiate off as well. Rreboot and you will see SIGNIFICANT increases in performance, we have seen times go from 15 minutes to 15 seconds to move the same data SAFELY!

Good luck!

I'll blame NT, because I love M$ so much :-)

As suggested, get CIFS9000 and then the NT's can mount your unix directory as an SMB file share, NT's like this a lot better!
