Problems with Login

Question

Hi We're trying the free edition of Kiwi Cattools - most of our devices are backuped perfectly. But we've got some troubles with the Hexatronic X2 CPEs. This device has an telnet server and with the implemented command nvbackup, we can send the running config to any tftp server. Now we created a new device: Device Type: Generic.Device Connect via: Direct connect Method: Telnet Set an AAA Username and Password. As the X2 has a bit another login prompt, I set custom "Username prompt" to login and "Password prompt" to password. Then I created a new activity: Device.CLI.Send.commands and added the command under Options. The main problem is, Cattools can't login to the Device, so I did a run with capture mode enabled:

Welcome to X2-10 Telnet Server[13][10][13][10]login:admin[13]admin[13][10] ================================================================================ WFMDRetVal=1 Waiting for: "password:" WFMDRetVal=2 Waiting for: "login:" WFMDRetVal=3 Waiting for: "% Login invalid" WFMDRetVal=4 Waiting for: "% Authentication failed" WFMDBuffer="admin[13][10]" ================================================================================ admin[13]admin[13][10] ================================================================================ WFMDRetVal=1 Waiting for: "password:" WFMDRetVal=2 Waiting for: "login:" WFMDRetVal=3 Waiting for: "% Login invalid" WFMDRetVal=4 Waiting for: "% Authentication failed" WFMDBuffer="admin[13][10]" ================================================================================ admin[13]admin[13][10][13][10][13][10]This telnet session has been idle for 600 seconds![13][10]

This is the correct behaviour. It is simple the device sending an echo of what CatTools is sending. CatTools sends: foobar[13] Device repsonds: foobar[13][10] My thoughts is that a Carriage Return [13] is not adequate enough for this device in order to actually fully action the username to the device. It may need a line feed control char too i.e. [13][10], in order to process the username and send the 'password:' response. You may like to try the custom device script to test this theory as you should be able to configure CRLF in this script as it is unencrypted. http://www.kiwisyslog.com/help/cattools/dev_creatingcustomdevice.htm Steve

Looks like the device has problems with the input method (or whatever) of CatTools... I checked the configurations again, and when I set "admin" as username, the Device returns 'admin' and if I set 'foobar' then I got foobar as return!

Welcome to X2-10 Telnet Server[13][10][13][10]login:admin[13]admin[13][10]admin[13]admin[13]admin[13][10]admin[13][10] or with foobar as Username:

Welcome to X2-10 Telnet Server[13][10][13][10]login:foobar[13]foobar[13][10]foobar[13]foobar[13]foobar[13][10]foobar[13][10]

The device sees to be returning an admin prompt instead of a password prompt.  we are looking for either:

WFMDRetVal=1 Waiting for: "password:"
WFMDRetVal=2 Waiting for: "login:"
WFMDRetVal=3 Waiting for: "% Login invalid"
WFMDRetVal=4 Waiting for: "% Authentication failed"

but instead we are getting "admin" returned.
