Script to Backup running config to local PC
I have very little experience with scripting and i was wondering if anyone could help me run a script that pulled the running configuration from all my devices in session manager?

I have run the following script that hangs on line 25. Basically, it's looking for the devices file, which i have not yet written :p

How could i change it to look through my session manager or export all the devices from session manager to a readable file for the vbs script to read?


#$language = "VBScript"
#$interface = "1.0"

' Test Script to log in via SSH/telnet and enters in privileged mode
' IF enable password is not set or you connect with TACACS/Radius directly in privileged mode,
' then comment the lines after Loop until the next comment section
' This version uses only one "devices.txt" file to store IP Address;hostname;username;password;enable password

Hi stamati76,

Presently there's not an easy way to iterate over the sessions in Session Manager. I have added this thread to a feature request in our product enhancement database to add Sessions object to scripting API for iterating over all sessions in Session Manager. Should a future release of SecureCRT include this feature, notification will be posted here.

If you prefer direct email notification, send an email to and include "Feature Request - Forum Thread #13398" in the subject line or use this form from the support page of our website.

There may be a way you can export the connection data. Please contact us via email ( and reference "Attn Brenda - Forum Thread #13398" in the subject line.

In your email please let me know the version of SecureCRT and what OS you are running it on.
