Select SSH as the desired protocol as shown below. Step 5: If this is the first time you are connecting to the Cisco Router or Cisco Switch, you will get a warning message as shown below stating that the Router's/Switch's host key is not cached. Also another thought, yoy said you use TACACS, is the TACACS server reachable from the location of the switch? Check routing and acls towards the TACACS servsr. In general it's good practice to configure a local fallback method, so that when tacacs is not reachable you can use a local user

It's actually a known limitation of Cisco, that it does not support multiple commands in an SSH exec channel command. Quoting section -m: read a remote command or script from a file of PuTTY/Plink manual:. With some servers (particularly Unix systems), you can even put multiple lines in this file and execute more than one command in sequence, or a whole shell script; but this is. 15. After installing the new public key, confirm that it is ready for use by looking in the Dropdown List in the Remove Key section. If your SSH key filename appears, then it is installed properly. DO NOT remove it. Here we see that there are two SSH keys currently installed on this node. 16. To use your SSH keys, open a new PuTTY session If a camera is down my script will then use Putty to SSH into the switch and do a shut / no shut on the port to reboot the camera. The script works perfectly as long you are logged in as it uses the SendKeys to pass the commands through to Putty. I tried Plink but it won't except the Enable command for the Cisco switch

I will show you how to configure your router as an SCP server and how to copy files to/from it By default, Telnet and SSH are disabled, you can enable them either by connecting through console and enabling them or enable them via GUI main page, there is an option to enable Telnet and SSH. Access through Console: 1. Connect console cable to your machine serial interface other end at console port in Switch. 2. Use Hyperterminal (if XP OS. In order to use Telnet, it has to first be configured though the CLI, using Putty or Minicom via console cable: line vty 0 4. local. transport input telnet . But @Juan and @Ing_percy have a point; in most real world scenarios you would restrict access to SSH, for security reasons, so then the command would look like this: line vty 0 The most common SSH client is probably putty. The only thing you have to do is to select the SSH protocol, enter the IP address and leave the default port at 22: You will see this on the putty console: as: admin Using keyboard-interactive authentication. Password: R1> You can also use another Cisco IOS device as a SSH client. Here's how

But the major advantage of using SSH over telnet is that it is secure protocol that encrypts the session between an SSH Client and an SSH Server. SSH uses TCP as the transport protocol and well-known TCP port 22 for establishing session to a SSH server. SSH Configuration for a Cisco Router is shown below. Router(config)#hostname hostnam It may just be that documentation is being created. This blog shows how to do so in a Cisco environment trying to find the IP address To find the port you must already have a good understanding of the network topology and have access to the switches CLI.

How to Configure SSH on Cisco Router or Switch? - Techni

There is a lot of special-case code in apps like Putty, to deal with idiosyncrasies found in various SSH servers, and it's not in the underlying SSH library used by Net::SSH. Plus, from hard-won experience, we've found that Cisco's SSH implementation changes from device to device because of the OS differences We have a newly installed 3850 and we have found that we can only ssh from another 3850 on the same code level. If we try using putty or a older switch it opens the port but the connection fails. The only thing I can find is this ip ssh encryption algorithm line and for some reason I cant negate it in the 3850

PuTTY is a free open-source tool you can use to connect and configure devices through SSH and Telnet. If for any reason you cannot use PuTTY, be sure to check out our list of PuTTY alternatives.
