Command Window Interactivity

[nolan.rumble]

Hi,

I'm utilizing the command window to send multiple commands through to single/multiple SSH sessions. However if I haven't prepared the commands exactly, sometimes the device sends an error back but SecureCRT still continues with sending all the commands through to the device.

Is there a way to abort the full send of commands if SecureCRT detects any errors in the resulting output?

An example would be configuring a Cisco router/firewall where before any commands are accepted, you need to be in "configure terminal" mode.

Let me know if you have any questions.

Thanks!
Nolan

Hi Nolan,

What version of SecureCRT are you using?

Changes in SecureCRT 8.0 (Beta 1) -- January 28, 2016 (8.0.0.1011)
-----------------------------------------------------
New features:

• Added a "Send Characters Immediately" mode to the Command window, which makes it possible to do the following in one or multiple sessions: stop commands using CTRL+C, edit files using an editor such as vi, send escape sequences, and do tab completion.
  

If v8.0 or later, if you enable Send Characters Immediately, issuing a Ctrl+C should interrupt the output. (It did in my tests to Linux remotes.)

Hi Brenda,

I'm running latest version.

I didn't know about the CTRL+C option. I'll try that next time.

What about the interactivity question? Is there a way to "program" the command window to automatically break from sending the whole set of commands when a command is sent and the remote device sends an error back?

Let me know if you have any other questions.

Thanks!

Hi Nolan,

Sorry, I didn't realize the perspective on that inquiry was of a programmatic nature. It's not possible at this time. The interaction is not really bi-directional when using Command window. There might be *some scripting solution* (or a feature request) possible, but I'm not sure how feasible it is.

What sort of errors do you expect?

Is the error received always the same?

Hi Brenda,

The errors can be varied an example would be to run this command on a Cisco ASA firewall without being in configure mode:

FW01> aaa-server
^
ERROR: % Invalid input detected at '^' marker.
FW01>
FW01> enable
Password: ********************
FW01# aaa-server
ERROR: % Incomplete command
FW01#


This is just an example of a firewall, the concept could apply to many other device types (routes/unix/linux/etc).

It would be great to have the command output match a regex (preferred, and ideally allowing for spaces in the regex) or list of exact string expressions to match on. If it matches, then abort sending the remaining list of commands.

Does that make sense?

Let me know if you have any questions.

Thanks!

Hi Nolan,

I have created a feature request on your behalf in our product enhancement database to provide a mechanism to bail from a multi-line (send to all) Command window (regular expression) and added this thread to it. Should a future release of SecureCRT include this feature, notification will be posted here.

If you prefer direct email notification, send an email to support@vandyke.com and include "Feature Request - Forum Thread #13220" in the subject line or use this form from the support page of our website.

Thank you Brenda! I appreciate it!
