12/6/2023 0 Comments Setup ssh tunnel with cyberduck![]() When you establish a connection to the VNC session running on your remote machine through either ssh tunneling or jump host, you will be asked to type in the password you set for your VNC session using the vncpasswd command as mentioned in the previous session. The CLI version of this method can be found in Gentoo wiki. There is an alternative to ssh port forwarding if you use MobaXterm’s VNC session setting: Another option in Windows to establish an ssh tunnel is to use PuTTY. Port forwarding ( MobaSSHTunnel) is also available under MobaXTerm’s tools menu. $ pgrep ssh # find the process id of the running ssh tunnel $ kill -9 pid # replace pid with the real process id given by the previous command Once your X Window server is running, you can let your ssh connection to the remote machine to send remote GUI program windows to your local machine and get displayed on your local X Window server: Windows users can use MobaXterm, Xming, or Cygwin/X to establish an X Window server in your local PC. Many editors can work inside a terminal, others create their own GUI, which have to be displayed in a X Window server. We can also use remote editors to edit remote files. ![]() We can edit remote files using local editors as we described in the previous section. Next time, when you log into the server, if the two keys match, you will be logged in without typing in your password. You upload the public one to the server and keep the private one secretly in your ~/.ssh. The basic idea is that you generate a pair of keys, one is private, one is public. Your password is saved as it is in ~/.netrc. Machine .ip login username password sZ right way $ chmod 600 ~/.netrc # hide it from others $ open ~/.netrc # edit it, put the following into it: You can save your connection information (including the password) in this file: This can also be achieved in the command line through a file called ~/.netrc. Normally, a GUI SSH client can save your password to the server so that you don’t have to type it next time. The same method works in Cyberduck and Filezilla. When you save your modification of the file, the updated version will be uploaded to the remote machine automatically. GUI programsĭouble click on a remote file shown in the MobaXterm side panel after you ssh into a remote machine, the file will be open in the MobaTextEditor. ![]() If you are an Emacs or Vim user, both editors provide commands to directly edit remote files. One can drag files in and out of it for copying. MobaXterm in Windows provides a nice side panel that shows files in the current folder in the terminal. You will now be at the SFTP prompt ready to enter commands.$ scp localFile #copy local file to remote machine $ scp localCopy #copy remote file to local machine $ scp localCopy #specify full path to a file $ scp localCopy.$ sftp If you receive a warning about host authenticity then check the key in the warning text against the table below – if the keys match then type yes, press Enter and then complete your login ![]() You will then be prompted for your SSO password.

All popular Linux distributions have built-in command line SSH and SFTP clients.
