Hello Everyone: I've been trying to get rsync using --bwlimit using openssh for transport without success. Here's what I get: % rsync --bwlimit=20 from.com:/dir/file.txt /dest user@from.com's password: **** rsync: unrecognized option `--bwlimit=20' unexpected EOF in read_timeout I tried specifying ssh transport using both the -e opti...

I am doing some benchmarking of rsync. I am using the --bwlimit= option to throttle down rsync to predict its operation over slow communications links. I am using rsync 2.6.2 from the release site without any patches. I downloaded the release rather than pull from the CVS tree. I have 2 servers "wilber" (the remote archive) and "judy" (the...

Hi, I have two issues with the --bwlimit parameter to rsync which are not mentioned in the FAQ (please correct me if I am wrong): 1. When both an rsync client and an rsync daemon specify the --bwlimit parameter, the client's value overrides the server's value. This could be used in a DOS attack if the client uses a larger valu...

Hi list, I couldn't find anything related to this, on mailing lists or even bugzilla, so here it is. A problem with this combination exists in the new 2.6.3 where the bwlimit code got rewritten and is not present at <= 2.6.2. The problem is that on io.c:882 bwlimit_writemax is also used to control the bandwidth, but it is not initialized for the daemon mode. At options.c:772 you can see the function returning and a bit bellow, line 810, bwlimit_writemax gets initia...

[I'm not subscribed, please CC me on replies] Some time after 2.6.0 the --bwlimit code was enhanced, but the code now doesn't work anymore when you set the bandwidth limit for the daemon and generates error log entries like: 2005/01/13 08:17:03 [29636] rsync: writefd_unbuffered failed to write 12 \ bytes: phase "unknown" [receiver]: Success (0) 2005/01/13 08:17:...

My impression when running with --bwlimit in combination with compression -z is that the speed to the filesystem is limited to the value given in --bwlimit. This must be contrary to the intention with --bwlimit. David

Does "bwlimit" option really work on rsync locally? We have one type of harddisk and want to slow down rsync I/O on disk because I don't want the disk head gets too hot. While I'm trying to use --bwlimit option, it looks the rsync speed was slowed down, but iostat is not improved at all. In both cas...

Hello! I cant get the bwlimit option working right. If i set this option over 400 kbyte per sec i still only get 400kbyte per sec, whether wich value i set. I try this option with a 100MB big file. I use a debian stable System with rsync version 2.5.6cvs protocol version 26. Can someone tell me how i can this get working? thx...

Wayne replied to my original note which said that in a special situation that I was using to probe rsync to build a behavioral model that bwlimit= resulted in bimodal behavior around a 4000 kbyte/sec value. He responded with a patch that I have tested in a limited way. I have a push scenario from a local site to a remote site. I use a file that is 6.3 Megabyte in size whose checksums (when written to batch) are 60k bytes and whose deltas (w...

Hi, I Emailed this afternoon that bwlimit leads to a much too low bwlimit if small amounts of data are sent in each write. I wrote a small patch now. Congrats on the code: It's nice and clean: I wrote a working patch in 5 minutes after examining a total of 25 lines of code. (My backup used to require two hours of small sleeps alon...

I am using rsync version 3.0.7. My rsync server is running on the cloud. I have set the bwlimit to 10 i.e. 10 KBps. When I try to sync files the bwlimit is as what is set. I have enabled storage of partial files. When a communication break causes rsync to time out during a transfer the partial file is stored in the partial directory. I then try rsync again when the link is up. At this point I...
