Kiwi CatTools

Firewall or network connectivity issues

Another cause for this might be that the device is setup to use "Cisco SSH"

and/or

Kiwi Cattools does not support the MAC Algorithm below:
MAC Algorithms:hmac-sha1-96





 

1.  Ensure that there is no Firewall or ACL that prevents Cattools from connecting to the device.
      Run a manual Putty session on the device to check if you get the same behavior.
2. If 'Cisco SSH' or Telnet is selected, change this to SSH2.

Or

1. Run this command on the device

show ip ssh | inc Encryption|MAC
Algorithms:aes256-ctr 
MAC Algorithms:hmac-sha1-96

2. After this change the algorithm using this command
