Re: [Fab-user] How set shell to none

[Zhigang Wang]

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 address@hidden "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 address@hidden

How to clone the same behavior in fabric? 

Using our fabric:

# python ilom.py -s address@hidden -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)

address@hidden Executing task 'ilom_get_mac'

address@hidden run: show /System ilom_mac_address

INFO:paramiko.transport:Connected (version 2.0, client OpenSSH_5.1)

INFO:paramiko.transport:Authentication (keyboard-interactive) successful!

address@hidden out: shell: Invalid credentials

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,

Zhigang
