List-Unsubscribe: , List-Archive: I think I'm seeing a uid wrap/overflow problem in the linux nfs client or userid libc stuff -- but it might be in the VMS NFS server... SERVER: VMS multinet NFS server CLIENT: 2.2.18 linux works ok with the 'nobody' account. nobody@ogre:/home/falcon > ls -la |grep phurst dr-x------ 2 nobody nogroup 199680 Jun 26 11:07 phurst I can list this dir and access files in it. CLIENT: 2.4.18 linux doesn't work with the 'nobody' account. nobody@teton:/home/falcon> id uid=65534(nobody) gid=65534(nogroup) groups=65534(nogroup),65533(nobody) nobody@teton:/home/falcon> ls -la |grep phurst dr-x------ 2 4294967294 4294967294 199680 Jun 26 11:07 phurst In this case the nobody account appears to go across as a -2 and the use of long int instead of short int somewhere is bouncing the uid/gid values up to the 4294967294 uid/gid number.. which causes some problems. Anyone else seeing this? Is this a linux NFS fix that is showing a multinet bug? eric Here is a tcpdump showing the -2/-2 stuff. teton:~ # tcpdump host pleiad tcpdump: listening on eth0 11:12:07.657523 teton.2306391190 > tyco.nfs: 108 getattr [|nfs] (DF) 11:12:07.657987 tyco.nfs > teton.2306391190: reply ok 96 getattr DIR 40755 ids -2/-2 sz 1536 11:12:07.658160 teton.2323168406 > tyco.nfs: 108 getattr [|nfs] (DF) 11:12:07.658649 tyco.nfs > teton.2323168406: reply ok 96 getattr DIR 40755 ids -2/-2 sz 1536 ------------------------------------------------------- This sf.net email is sponsored by: Jabber Inc.
