  • Limits the usage of bandwidth by apt-get, in the example the command will use 30Kb/s ;) It should work for most apt-get actions (install, update, upgrade, dist-upgrade, etc.)


    16
    sudo apt-get -o Acquire::http::Dl-Limit=30 upgrade

  • the command is obvious, I know, but maybe not everyone knows that using the parameter "-l" you can limit the use of bandwidth command scp. In this example fetch all files from the directory zutaniddu and I copy them locally using only 10 Kbs


    11
    scp -l10 pippo@serverciccio:/home/zutaniddu/* .

  • in Debian-based systems apt-get could be limited to the specified bandwidth in kilobytes using the apt configuration options(man 5 apt.conf, man apt-get). I'd quote man 5 apt.conf: "The used bandwidth can be limited with Acquire::http::Dl-Limit which accepts integer values in kilobyte. The default value is 0 which deactivates the limit and tries uses as much as possible of the bandwidth..." "HTTPS URIs. Cache-control, Timeout, AllowRedirect, Dl-Limit and proxy options are the same as for http..."

    sudo apt-get -o Acquire::http::Dl-Limit=20 -o Acquire::https::Dl-Limit=20 upgrade -y
