Short form:
You can limit the bandwidth the scp uses with the -l switch, you pass a number that's in kbits/sec.
I'd rather set this in my .ssh/config file for certain names machines.
What's the equivalent named setting for -l ? I haven't been able to find it.
Followup question:
Generally, not sure how to map back and forth between ssh command line options and config names, short of doing Google searches or manually comparing man pages on a case by case basis. Is there a table that directly equates the two?
Longer form of first question, with context:
I've started using ssh config quite a bit, especially now that I need to go through a proxy and do lots of port mappings. I even define the same machine more than once depending on what type of tunneling I need.
However, when uploading a large file, it's difficult to do anything else on my machine. Even though I have more download bandwidth than up, I think that scp saturates the link so even my small requests can't reach the Internet.
There's a fix for this, using the -l bandwidth command line switch for scp.
scp -l 1000 bigfile.zip titan:
I'd like to use this in my config instead, so I'd create an additional named entry called "titan-upload" and I'd use that as the target whenever I upload.
So instead of:
scp bigfile.zip titan:
I'd say:
scp bigfile.zip titan-upload
Or even set different caps depending on where I am:
scp bigfile.zip titan-upload-from-home
vs.
scp bigfile.zip titan-upload-from-work
I'm generally on Mac and Linux.
