    SCP limit bandwidth

      I am trying to limit the bandwidth used on a SCP, seraching the net other flavors of unix have a -l option for SCP that allows them to limit bandwidth but all of my solaris 10 boxes do not have this. Is there a way to limit bandwidth on transfers (I would prefer to not have to install additional software packages) .

          You might try the sshd package from sunfreeware.com. I haven't looked but it might have that option compiled into it.

            Thanks, but it looks like you have to pay to download things off that site, not willing to cough up money for a possible answer. Anything else I can do to limit the bandwidth? I've got some remote sites that need to send something rather large, but I don't want to chew the entire link for the users.

              The other option would be to do what SunFreeWare does. Download it and compile it yourself. If you need assistance let me know.

                The latest update of Solaris10 1/13 (s10u11) has rsync freeware built in:

                ( http://docs.oracle.com/cd/E26505_01/pdf/E27003.pdf )

                I believe rsync is able to throttle bandwidth.


                rsync will as said before available from sunfreeware .... last time I looked an older version was available for download ... newer versions require payment.
                opencsw is another source of a binary package ... but can be more involved and probably not worth it for a single package as might require additional support packages from them as well.
                (As Alan said above compiling a version of scp might be more beneficial in this circumstance).

                  Thanks for all the responses, rsync would be great to use, I had read on this earlier. But unfortunaly I cannot use it as my network requires only the use of port 22 and rysnc uses port 873. I can set it to change it but I'm not sure what effect I would have being sshed into a machine on port 22 and initated a transfer with a different protocol on the same port. Compiling my own is ok, can you guys direct me where I can get the latest version of scp that includes the options I need, I really don't understnad how to navigate sunfreeware.

                    Google "rsync over ssh"....

                      Thanks for the help and ideas guys, it took a little bit but I got rsync over SSH to work and limit my transfer speeds.
