Subject: [9fans] Drawterm /mnt/term permissions issue
Topicbox-Message-UUID: 049b6d92-ead5-11e9-9d60-3106f5b1d025

I run a plan 9 cpu server in Qemu and use drawterm to connect from the Linux host.  I thought the /mnt/term mechanism would be very convenient for exchanging files between host & guest, but the guest sees all user/group names as unknown/unknown, preventing writing.

Within drawterm:

sauvo> echo $user
ethan
sauvo> cd /mnt/term/home/ethan/tmp
sauvo> ls -l
d-rwxr-xr-x M 80 unknown unknown 4096 Jun  4 19:52 glibc-2.9
--rw-r--r-- M 80 unknown unknown 5539 Jun  2 21:57 installed
sauvo>

In Linux:

ethan@vardo $ pwd
/home/ethan/tmp
ethan@vardo $ ls -l
total 12K
drwxr-xr-x 67 ethan ethan 4.0K 2009-06-04 19:52 glibc-2.9/
-rw-r--r--  1 ethan ethan 5.5K 2009-06-02 21:57 installed
ethan@vardo $

Is this a drawterm issue? If so...

I can understand drawterm mapping most user & group names to unknown, but shouldn't I be able to write to my own files? This could be solved if drawterm mapped the username of the running user to that of the logged in user.

To illustrate how I think that mapping would appear in use, if my username on my Linux box was was "geoff", and used drawterm to log in to a plan 9 machine as user bootes the above example would appear as follows:

plan9host> echo $user
bootes
plan9host> cd /mnt/term/home/geoff/tmp
plan9host> ls -l
d-rwxr-xr-x M 80 bootes bootes 4096 Jun  4 19:52 glibc-2.9
--rw-r--r-- M 80 bootes bootes 5539 Jun  2 21:57 installed

geoff@linuxbox $ cd ~/tmp
geoff@linuxbox $ ls -l
total 12K
drwxr-xr-x 67 geoff geoff 4.0K 2009-06-04 19:52 glibc-2.9/
-rw-r--r--  1 geoff geoff 5.5K 2009-06-02 21:57 installed
