Hi,

I just tested the posted SRPM for RHEL5.  Builds fine in mock for me.  However,
when I try to use the service, I get:

[brian at brian-test vdt-release]$ sudo /sbin/service gsisshd start
Starting gsisshd: Could not load host key: /etc/gsissh/ssh_host_rsa_key
Could not load host key: /etc/gsissh/ssh_host_dsa_key
                                                           [  OK  ]

I hand-generated new keys and hand-changed the port to 23 from 22 (conflicting
with normal SSH), and the server worked.  Even properly invokes the Globus
plugin infrastructure!

However, when logging out, zombie processes were left over.  Process tree looks
like this:

root      6807  0.0  0.0 165308  6052 ?        Ssl  07:42   0:00 gsisshd: brian
[priv]
brian     6823  0.0  0.0 165308  3208 ?        S    07:42   0:00  \_ gsisshd:
brian at pts/11
brian     6824  0.0  0.0      0     0 ?        Zs   07:42   0:00      \_ [bash]
<defunct>

After installing debuginfo RPMs, I get see the middle process (6823) has the
following stack trace:

(gdb) bt
#0  0x00007f1123eeb212 in select () from /lib64/libc.so.6

#5  0x00007f11281ebf00 in main (ac=<value optimized out>, av=<value optimized
out>) at sshd.c:1797

Maybe we should bring the gsissh devs into the loop on this one?
