The “ -l” parameter will limit the bandwidth to use. Limiting Bandwidth Usage with SCP CommandĪnother parameter that may be useful is the “ -l” parameter. Please be careful that this parameter using “ -c” not “ -C“. ![]() The above command tells SCP to use the 3des algorithm to encrypt the file. If you want to change to another cipher to encrypt it, you can use the “ -c” parameter. Change SCP Cipher to Encrypt Filesīy default, SCP uses “ AES-128” to encrypt files. iso files will not be affected by the “ -C” parameter. When the source file is already compressed, you will not find any improvement there. The thing that we should notice is that the compression method will not work on any files. If you are copying a lot of files across the network, the “ -C” parameter would help you to decrease the total time you need. It is 10 times faster than not using the “ -C” parameter.
