Compress Ssh Connections

If you use the SSH remote login tool over a slow connection, you’ll often find a high latency between typing and the characters appearing. SSHing between two boxes on dialup lines often results in horrible juddering. Thankfully there’s an easy way round this: compression (sending less data down the line). By using the -C flag with OpenSSH you can apply compression to the connection, improving response greatly, and this uses the same methods as gzip. You can even apply -C to scp; however, if the file or files you’re transferring are already
compressed it’ll only slow it down. Here’s an example login command with the compression flag:
