I'd like to use the 9p mounting available in Linux, but it doesn't seem to work in this case. I try "mount -t 9p glenda /mnt" (glenda is my cpu/file server) and get: mount: wrong fs type, bad option, bad superblock on glenda, missing codepage or helper program, or other error (for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.<type> helper program) In some cases useful info is found in syslog - try dmesg | tail or so If I do "mount -t 9p 192.168.18.180 /mnt", using the file server IP, I just get mount: permission denied But dmesg shows "[88617.144804] p9_errstr2errno: server reported unknown error cannot attach as none before authentication", ONLY when I use the IP address--nothing appears when I use the /etc/hosts alias "glenda".
