hi all, it appears this type of error hasn't been seen since the late 90's or so, and the fix then doesn't apply to now. i have a remote-mountable HP logic analyzer (HP 16500B) that provides an NFS export at /control and /data. network-wise, it's configured fine -- it can talk to the world, the world can talk to it via ping, telnet, and ftp. where it's falling down is when i try to NFS mount the spaces: root@hammett # mount hp16500b:/control /mnt/16500b/control/ mount: RPC: Authentication error; why = Invalid client credential i've tried playing with "-o nfsvers=2" and such, but nothing i do seems to really change it. way back in '95-'98, there was some discussion about seeing this error on occasion. the answer was to be sure "root" didn't belong to >= 8 groups. on the PC (modified RH8) that's not an issue. root belongs to 4 groups. obviously on the HP box, there's very little i can configure. the idea of "root" doesn't even exist. does anyone have any suggestions for how to get around this problem? thanks, josh fryman - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
