A Cisco switch needs to be prepared for SCP before sending files, typically for a software upgrade. The following commands are therefore necessary:. The user you are using to send files to the switch must be configured with high privileges. You can give the user level 15 privileges temporarily to get your file transferred. Once done, ensure you have Putty installed using the installer file found at Putty.
Once this command is passed you will be asked for the password for the user used to access the cisco device and then you should see a status bar showing you the file transfer is in process:. Ensure the file checksum is correct by comparing it with the original file size on your windows device.

Rafay Rasool. How to use SCP to transfer files to and from a network device Next Post Cisco port configuration: Access port and Trunk port.Linux administrator should be familiar with CLI environment.
Since GUI mode in Linux servers is not a common to be installed. SSH may the most popular protocol to enable Linux administrator to manage the servers via remote in secure way. SCP is used to copy file s between servers in secure way. There are much parameters in SCP command that you can use. Here are the parameters that may useful on daily basis usage. Basic SCP command without parameter will copy the files in background.
User will see nothing unless the process is done or some error appears. It can help you debugging connection, authentication and configuration problems.
An estimated time and the connection speed will appear on the screen. The unique thing is the compression is only happen in the network. When the file is arrived to the destination server, it will returning into the original size as before the compression happen. As you can see, when you are using compression, transfer process is done in The thing that we should notice that compression method will not work on any files.
When the source file is already compressed, you will not find any improvement there. Files such as. Take a look of this command. Above command tell SCP to use 3des algorithm to encrypt file. It is mean that 8 bits equal with 1 byte. Usually SCP is using port 22 as a default port. But for security reason, you may change the port into another port.Post a Comment.
This has the advantage of not having to setup a TFTP server on your computer and the file transfers are encrypted. Encryption should must? On Windows you can use the Putty companion program pscp. In other words, when you log in over SSH, you must end up at a prompt. See the Cisco Support forum article "Privilege Denied message" in the Reference section below if you get a Privilege denied message. Here is an example:.
Notice that it took the "b" then terminated on the symbol and returned the rest of the password as an error. The user was doing the copy with WinSCP and it popped up a dialog saying it received invalid data. I switched to Putty SCP and it was immediately clear what the problem was. I created a new user with a valid password and the SCP transfer succeeded:.
I recently went to scp a file to a switch and received this on the switch ip I ran ip ssh ver 2 on the switch and it resolved the issue. Cisco link for SCP configuration. No comments:. Newer Post Older Post Home. Subscribe to: Post Comments Atom.On Unix-like operating systems, the scp command copies files over a secure, encrypted network connection.
The scp command can be thought of as a network version of cp. For example, you might use the following cp command:. Or, you could specify a remote location as the source location if you want to download files.
For example. You can also specify a remote host as both the source and destination. For instance, the following command will transfer a file from one remote directory on myhost.
Keep in mind that all scp transfers have the benefit of being secure: they are encrypted, like an ssh or sftp session. It uses ssh for data transfer, and uses the same authentication and provides the same security as ssh. Unlike rcpscp will ask for passwords or passphrases if they are needed for authentication.
Local file names can be made explicit using absolute or relative pathnames to avoid scp treating file names containing ' : ' as host specifiers. Copies between two remote hosts are also permitted.linux ubuntu secure copy (SCP) file transfer tutorial
Copies the file myfile. The transfer will go directly from one remote host to the other. Same as the above command, but rather than directly transferring the file from one remote host to the other, the transfer is routed through the local host.
Home Help Linux. Was this page useful? Forces scp to use protocol 1. This is an older protocol. Copies between two remote hosts are transferred through the local host. Without this option the data is copied directly between the two remote hosts. This option also disables the progress meter. Uses batch mode, operating without any interactive keyboard input.
This means that scp cannot authenticate the session by asking the user to type in a password; therefore, a non-interactive authentication method is required. For an example of setting up non-interactive authentication, see Setting Up Public Key Authentication in our sftp documentation. Enable compression, which passes the -C flag to ssh to enable compression of the encrypted connection.
Secure Shell Configuration Guide
Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh. Specifies an alternative per-user configuration file for ssh. Selects the file from which the identity private key for RSA authentication is read. This is useful for specifying options for which there is no separate scp command-line flag. Valid options are: AddressFamily. Specifies which address family to use when connecting.
Valid arguments are " any ", " inet " use IPv4 onlyor " inet6 " use IPv6 only. Also, the ServerAliveInterval option will be set to seconds by default.
This option is useful in scripts and other batch jobs where no user is present to supply the password, and where it is desirable to detect a broken network swiftly. The argument must be " yes " or " no ". The default is " no ".I am having trouble getting scp to work in my network.
SCP Example Cisco ASA to Linux
They have set up a Ubuntu server as the file server and set it to use our Windows Active Directory credentials to log in. I used the following command to do the copy:. This works. I don't want to have each person on the network team to have a copy of each IOS on the server. I only want the current version we are using and in a folder that everyone can use. How do I change the first command so it can change to the correct folder to find the file? Go to Solution. View solution in original post.
You need to specify the full path to the data folder. Is the data folder a sub-directory of another folder? You also need to ensure you have permissions to the data folder.
I figured out how to correct the problem I was having. I created a symbolic link between my folder and the folder where the files need to be located. That allows me to moved around in my home directory to the correct folder. For example:. The problem is we don't want each administrator to have their own folder with data in it. We want all of the data to be in a folder located off of the root drive.
When I move the file to my home folder, this is a Linux machine, I was able to download the file. I had to create a symbolic link to where the data needs to be stored. The I could use the link to get to the correct folder and the file I was trying to copy to the switch. Buy or Renew. Find A Community. We're here for you! Turn on suggestions.

In addition, SCP requires that authentication, authorization, and accounting AAA authorization be configured so that the device can determine whether the user has the correct privilege level.
An authorized administrator may also perform this action from a workstation. The exec keyword runs authorization to determine if the user is allowed to run an EXEC shell; therefore, you must use the exec keyword when you configure SCP. This example uses a locally defined username and password.
