Hello,
Currently I am checking if our users can work, when one (not all) of
our AFS database servers is down.
The tests were made with Linux 2.4.28-rc1, OpenAFS 1.2.13. To simulate
a database server which is down, I set one database server IP address
to a machine on the local subnet, which does not run any AFS servers.
(1) /bin/login: takes some time, but works
(2) /usr/X11R6/bin/xdm: hangs forever
I wrote a small test program, which uses similiar calls to PAM as xdm
does. These calls are:
pam_start
pam_authenticate
pam_acct_mgmt
pam_setcred
pam_open_session
fork
parent:
wait for child
child:
pam_setcred
pam_end
This test program hangs within the child "pam_setcred" (like xdm).
Using tcpdump I can see that no more packets are sent to/from the
machine running the program.
If I omit the "fork" call, the program succeeded in getting a token.
Of course this needs some time, because the program first tries to
connect to port 7004 of the wrong DB machine.
Any idea or help?
