RE: rsync problem behind a router

2002-12-19 Thread tim . conway 
I was afraid of that.  I'd hoped that it would show more.  Next thing i'd 
try would be to, on the remote end, write a rsync wrapper script, that 
starts rsync inside a strace (or truss, or tusc, or whatever your OS 
uses), directing it to follow forks, redirecting STDERR to a file.  Do 
another super-short run, using --rsync-path= to point at the wrapper, then 
scan down that trace output.  If you don't see a solution right away, post 
that output here.  If we find that the rsync process suspends itself 
waiting for io, it's probably a transport thing.Rsync is known for 
revealing weaknesses in TCP/IP implementations, though I wouldn't expect 
to see it in small jobs.

you try a run with "-vvv"? That's more likely to reveal exactly what
it's 
failing on, though (AFAIK(IIRC)) it won't tell you about stuff on the

That's what I originally though too...I've tried it on one small
idex.htm file, and it does the same thing...

Does it work for very small transfers?

Does it work with --bwlimit set low enough so you never saturate your
link?

I can not rsync large amounts of data through my LinkSys without using
the
--bwlimit option.  My LinkSys is doing NAT.  I think it loses track of
the
address translation for the ssh connection under load.  Then the ssh
session just stops.  I use --bwlimit=100, which is a third of the
available bandwidth on the far end, and it just works.

It's not a problem particular to rsync, other ssh sessions sometimes
hang
too.  I just have more problems with rsync because I move more data that
way.  I always use "screen" for interactive sessions.

Could be a different problem, mine would often transfer quite a few
files
before stopping.

rsync problem behind a router

2002-12-17 Thread Chad Moss 








I have used rsync on many systems,
and never had a problem.  I am
stumped on what to do with this…

I have a box behind a LinkSys
router and I can not “push” or “pull” data to or from
it from anywhere…

When I try, it logs into the remote server, gets the file
list and just stops.

The remote server shows a process running until I control-c out of it…when I do that, I get:

 

rsync error:
received SIGUSR1 or SIGINT (code 20) at rsync.c(229)

rsync error:
received SIGUSR1 or SIGINT (code 20) at main.c(785)

 

The command I am using is:

rsync -avz -e ssh [EMAIL PROTECTED]:/home
/home/backup/servername/

 

I have forwarded ports 22 and 873 to that machine, and I
have tried putting it in the DMZ.

The results do not seem to change.

 

Thanks.
