Pervasive Permission Problem
Salutations,
Please respond to me directly since I've been removed from this alias.
I'm setting up a network talking to a Debian server. While I've managed
to figure out many of the problems I am still entirely unable to give
other systems write access to this system. I'm hoping it's due to one or
two simple common issues. I have an intermittent permissions problem
associated with pppd but I can't reproduce that one today. Here is the
permissions problem I'm dealing with now.
When a remote system (dilthey) mounts up my home directory from alpher
(the Debian system) everything indicates it's r/w. For example:
dilthey:~> mount
/dev/hda2 on / type ext2 (rw)
/dev/hda5 on /usr type ext2 (rw)
/dev/hda6 on /usr/local type ext2 (rw)
/dev/hda1 on /win32 type vfat (rw)
/dev/hda7 on /workspace type ext2 (rw)
none on /proc type proc (rw)
automount(pid175) on /home type autofs
(rw,fd=5,pgrp=175,minproto=2,maxproto=3)
automount(pid186) on /apps type autofs
(rw,fd=5,pgrp=186,minproto=2,maxproto=3)
automount(pid196) on /mnt type autofs
(rw,fd=5,pgrp=196,minproto=2,maxproto=3)
alpher.taylors.org:/export/home/julian on /home/julian type nfs
(rw,addr=172.16.0.1)
and on alpher:
alpher:~> cat /etc/exports
# /etc/exports: the access control list for filesystems which may be
exported
# to NFS clients. See exports(5).
/export/home (rw)
/export/usr/dist (ro)
and yet:
dilthey:~> touch notion
touch: notion: Operation not permitted
dilthey:~> mkdir test
mkdir: cannot make directory `test': Permission denied
dilthey:~>
A Sparcstation on the network shows the following snoopnetwork activity:
172.16.0.4 -> alpher.taylors.org NIS C DOMAIN taylors.org
alpher.taylors.org -> 172.16.0.4 NIS R DOMAIN OK
172.16.0.4 -> alpher.taylors.org NFS C LOOKUP2 FH=42C9 notion
alpher.taylors.org -> 172.16.0.4 NFS R LOOKUP2 OK FH=ACC9
172.16.0.4 -> alpher.taylors.org NFS C SETATTR2 FH=ACC9
alpher.taylors.org -> 172.16.0.4 NFS R SETATTR2 Not owner
172.16.0.4 -> alpher.taylors.org NFS C LOOKUP2 FH=42C9 test
alpher.taylors.org -> 172.16.0.4 NFS R LOOKUP2 No such file or
directory
172.16.0.4 -> alpher.taylors.org NFS C MKDIR2 FH=42C9 test
alpher.taylors.org -> 172.16.0.4 NFS R MKDIR2 Permission denied
172.16.0.4 -> alpher.taylors.org NIS C DOMAIN taylors.org
alpher.taylors.org -> 172.16.0.4 NIS R DOMAIN OK
This looks like confusion over who I am but on dilthey, I get
dilthey:~> ls -l notion
-rw------- 1 julian users 16384 Jan 5 1997 notion
dilthey:~> ypmatch julian passwd
julian:x:501:100:Julian S. Taylor:/home/julian:/usr/bin/tcsh
Any ideas?
Julian
