Back from Paris where I was for work. A pretty hard problem to solve with NFS (connect error on some requests).
In fact the client doesn’t receive server’s replies on port 623 … the packets are on the network (according to network analyses) but not on the tcpdump output ! After some investigations, the problem is due to intel gigabyte cards which use port 623 for some extras function (as a serial connexion on the card) and just keep all the packets on this port … so linux never receive any packet here.
Setting a TCP and a UDP server on port 623 is enough to prevent NFS to use it (NFS client send uses 600-1024 port range) and to fix the problem (… but really a hack). Does somebody know a better way to do this ?
Enough with the job. After some days away from the PC I’ve a lot of mail to read … and also some new bugs to deal with, it will do some work for the week end!.
