[Dev] cisco IOS retrieval failure

Everything Brett said is true.
Is your device listening on TCP\22? If not, ziptie will go right to telnet. Adapter Tool just does what you tell it though. It has no trial and error logic.

PingShan,
I’ll let Ryan reply to some of this, but I’ll answer a few. ZipTie tries protocols from “most secure” to “least secure” order, so it should be the case that if both SSH and Telnet are defined, that it will select SSH. If it is not, it’s a bug in my opinion.
When the ZipTie server is driving the adapters for backup, it will submit one set of protocols at a time to the adapter until it succeeds or runs out of configured protocols or that device. So, if you have SSH-SCP-Telnet-TFTP supported by the device and enabled as protocols, ZipTie will probably first attempt SSH-SCP for backup. If that fails, it will attempt SSH-TFTP, then SSH, then Telnet-TFTP, and finally Telnet. Ryan, correct me if I’m wrong.
In regards to SSH not failing immediately, it should. Something else is going on here, like a failure response that we’re not expecting. I’ll let Ryan help you with that as he is more familiar with it.

Thank you for your reply.
I downloaded the AdaptorTool program, one question I have is about the protocol. I have a Cisco IOS device that only supports telnet. If I use telnet, the retrieval works fine. But if I use SSH, it hangs ( i waited for 3 min ). SSH should not work in this case. But it would be nice to return immediately if SSH connection failed. Is there anyway i can make changes to the perl script and return immediately if SSH is not supported by the device?
Another question is about which protocol to use.
from core\org.ziptie.adapters\scripts\ZipTie\CLIProtocolFactory.pm, I think the algorithm to choose protocol is:
1. If only SSH is defined, it uses SSH.
2. If only Telnet is defined, it uses telnet.
3. If both SSH and telnet are defined, it will choose telnet and will not try SSH.
Sometime I do not know what protocol the device supports. It can be helpful if i can specify the sequence of the protocols to try. For example, try SSH first, then try telnet. Is it possible to do this by changing the current perl script or iosInvoke.xml? If it is possible, would you please give me a direction on how to do it?
If i do a retrieval from Ziptie client and three protocols are chosen for the Cisco device. Does ziptie try all the protocols at the same time or try them one by one to see which protocol the device supports?
Thank you

PingShan Li,
Instead of running the Perl script directly, I suggest downloading our AdapterTool program.
We have details docs here:
http://staging.ziptie.org/documentation/latest/Content/index.html#d0e254 <http://staging.ziptie.org/documentation/latest/Content/index.html#d0e254> <http://staging.ziptie.org/documentation/latest/Content/index.html#d0e254>
Those docs will soon more, so try this link if the one above doesn't work for you.

I am a newbie to ziptie and I have a problem with ziptie for cisco retrieval. Please let me know what I need to do to make it work.
Thanks
