clicrud's Issues

ICX6430 connect hangs

On a ICX6430 (and FLS-48G) python hangs during the transport command while trying to run the command transport = device(...). I cannot enter any command after that line until i Control-C that task.

clicrud-paramiko.log shows that the script successfully logins in.

It doesn't matter if i connect via SSH or Telnet.

A test run on a VDX 6740 worked fine.

ICX6610-48P Password Prompt

Connecting to a ICX6610-48P running 07.4.00dT7f1 fails. It appears that the password prompt is caught by and sent from the if statement in clicrud/clicrud/device/generic/ver/base/init.py on line 137, but immediately after that if statement _detect is set back to True and clicrud is caught back trying to read for a password prompt and fails because the device is now at the device prompt.

class ssh(object): - ssh 'hangs'

After a reinstall and upgrade to version 0.2.13 from version 0.1.4 we could no longer send commands to the brocade. (ssh hangs)

Seems like the following additions is causing issues:
509 self.output = self.blocking_recv()
510 self.output = self.blocking_recv() (this second statement seems to work fine with NOS)
Commenting out 510 does work, however the 'show version' command is causing paging so to fix this we could add:
if _NOS_present:
self.client_conn.send("terminal length 0\n")
else:
self.client_conn.send("q\n")
self.output = self.blocking_recv()
self.client_conn.send("skip\n")

Then this module works again however it breaks NOS.

We have replaced everything below line 503 with the code of version 0.1.4
if "#" in self.output:
self.client_conn.send("\n")
self.output = self.blocking_recv()
self._hostname = self.output.translate(None, '\r\n')
self.client_conn.send("skip\n")
self.output = self.blocking_recv()

Thanks, Jeroen

Vrouter support

We could really do with vrouter capability as well.

Use a 'standard ssh server like OpenSSH' as a proxy host for connection

This is an important feature needed when using CLICrud to connect to devices from 'outside' the customer domain where an intermediate DMZ/jumphost is often used.
