[9fans] mount with different username

[9fans] mount with different username

Hi fans!

I want to mount my filesystem on a linux machine from plan9.
u9fs.log says:

    u9fs
    kill 23121
    <- Tversion tag 65535 msize 8216 version '9P2000'
    -> Rversion tag 65535 msize 8216 version '9P2000'
    <- Tattach tag 15 fid 527 afid -1 uname bence aname
    ruserok(, bence) not okay
    -> Rerror tag 15 ename u9fs: rhosts authentication failed

My username is not bence but bfabian on the linux system.
That seems to be the problem. I guess maybe i should use
the -k option of mount(1) but -k 'user=bfabian' doesn't seem
to be enough.

Any input?

Thanks,
BenceF

When I login with drawterm, I need to use both -u (for drawterm)
and -k (for factotum if I remember well), maybe this is the same for
mount:

   -u bfabian -k 'user=bfabian'

Can't find -u in mount(1) as well as -k in drawterm usage().

Sorry, after a quick code exploration (mount.c), I think
this is a wrong assumption.

what do you have in your factotum for that dom? (i.e. grep linuxboxname
/mnt/factotum/ctl)

Nothing except the ssh entry.
I try to do
mount /srv/u9fs /n/linuxbox
/srv/u9fs is a pipe through ssh to the linuxbox running u9fs.
I'm trying to use p9any on the u9fs side.
When i run the command on the linux box it is fine
but when run through ssh it exits immediately.
Most probably an oversight on my part somewhere.

I'll try to find what did i mistyped. I use absolute path for
the key file so that can't be it.

If still can't make it work I'll try with execnet(4).

Ok. What do I do wrong?

execl("/bin/ssh", "ssh", argv[1], "u9fs", "-Dnza", "p9any", "-A", argv[2],
nil);

Seems it gets the -Dzna p9any, but not the -A keyfile

Hi!

Seems ssh takes only a fixed number of arguments as cmd.

term% ssh bfabian@<linuxbox> echo `{seq 20}
1 2

Passing it in one argument in exec works.
However! Tattach still sends "bence" (my plan 9 user) as uname.
How could i change that to bfabian?

BR,
Bence
