Thanks.
Currently I hit this:
http://net-ssh.lighthouseapp.com/projects/36253/tickets/32-sun-ilom-wont-accept-commands-even-after-successful-login
Maybe a ILOM bug, but they have workaround:
Doesnt' work:
$ ssh -t root@ca-dev33m "show /SYS"
Warning: Permanently added 'ca-dev33m,10.211.2.238' (RSA) to the list of
known hosts.
Password:
shell: Invalid credentials
Connection to ca-dev33m closed.
Works:
$ echo "show /SYS" | ssh -T root@ca-dev33m
How to clone the same behavior in fabric?
Using our fabric:
# python ilom.py -s root@ca-dev33m -p changeme
/usr/lib64/python2.6/site-packages/Crypto/Util/number.py:57:
PowmInsecureWarning: Not using mpz_powm_sec. You should rebuild using
libgmp >= 5 to avoid timing attack vulnerability.
_warn("Not using mpz_powm_sec. You should rebuild using libgmp >= 5 to
avoid timing attack vulnerability.", PowmInsecureWarning)

It may related to the buffersize? How can I enlarge the buffersize for
fabric?
I tried env.linewise=True, it doesn't help.
I will continue debugging on it.
Thanks,
