Ssh download file pipe
SSH handles the authentication on the destination host, and it moves the file in an encrypted tunnel provided by default with SSH. For SSH authentication, usernames and passwords can be used. However, SSH public and private key authentication are recommended as a security best practice. For the first example, we copy an Azure configuration file up to a Linux VM that is used to deploy automation.
Because this file contains Azure API credentials, which include secrets, security is important. The encrypted tunnel provided by SSH protects the contents of the file.
The following command copies the local. The admin user name on the Azure VM is azureuser. Substitute your own values in this command. For this example, we copy a directory of log files from the Linux VM down to your workstation. A log file may or may not contain sensitive or secret data. However, using SCP ensures the contents of the log files are encrypted. Using SCP to transfer the files is the easiest way to get the log directory and files down to your workstation while also being secure.
The -r flag instructs SCP to recursively copy the files and directories from the point of the directory listed in the command. Also notice that the command-line syntax is similar to a cp copy command. This command will upload a file - MS Note you still need touse the private key you used to connect to the Amazon instance with ssh.
Inthis example, it is the amazon. If you want a more user-friendly tool to transfer data, FileZilla is agood choice.
However for Amazon instance, we use key-pair to log ininstead of password for better safety. So it is a little bit more complicatedto configure. This is pretty much the same as above, except you want to transfer a bunch of files and leave them as a tarball on the server rather than as a bunch of files.
You can also encrypt the tarball so that you'll have protection in case your backup server is hacked, gets stolen, or gains sentience.
If you have a GPG keyring set up:. Note that you can choose a cipher other than RC4. Just remember what the cipher was when decrypting this should all be on one line :. Most of the time when I boot Knoppix , it's because my regular OS won't boot or is broken. It's often caused by a hard drive issue, so I want to make sure that as much data is safe as possible before I go poking around. This will copy the entire drive into a file on the remote machine:.
You can also copy individual partitions like sda1 and sda2 instead of entire drives like sda , sdb , etc. If you have two machines with identical hard drives for instance, if you bought a replacement or got an RMA , you can clone them by replacing sda. Note that to read or write block devices like sda requires you to be root.
Be very careful with dd as it's very deadly if used carelessly. Say you have a little script that you want to run once on a remote machine. You could scp it, but then you'd have to log into the other machine and run the command -- that's three commands! It is quite obvious that, for more number of files, we can use SFTP. It is difficult to say whether these will work with puTTY , may be with CygWin , it is possible to use the commands. Windows users possibly need this kind of setup — Translucent Console for Windows.
Actually there are lot of ways to download a file from SSH session. But, if you know about Pipe or Pipeline , then it becomes quite easy. Worst method probably is using scp. We can not say that we are using SSH, the Terminal software only remaining the same. Here is example :. This cheating answer is usually found on Question-Answer websites. Piping is the right, genuine pure SSH way :.
