Rsync over SSH-tunnel A-B-C using daemon on C
Dear, I'm trying to put up a scripts to synchronize my computers (HOST_A and HOST_C). I can connect both via HOST_B to avoid the firewall. I am trying to work with the rsync daemon to avoid hanging. I tried to figure out the mailinglist + FAQ, how to do it, but it seems I misunderstand something, since all your previous help did not work for me. I get the following error when executing the rsync-step: Failed to connect to HOST_C: Connection timed out (116). The scipt I now use is: # On HOST_A the following commands are executed # Start rsync daemon on HOST_C and check rsyncd.conf file ssh HOST_B ssh HOST_C rsync --daemon ssh HOST_B ssh HOST_C cat /etc/rsycd.conf # Create SSH-tunnel ssh -fN -l myusername -L 8873:HOST_B:8873 HOST_C # Rsync folders rsync -auv rsync://HOST_C:8873/module_on_HOST_C/folder_on_HOST_C /folder_on_HOST_A # Close rsync daemon on HOST _C and SSH-tunnel ssh HOST_C killall rsync killall ssh Disclaimer: http://www.kuleuven.be/cwis/email_disclaimer.htm -- To unsubscribe or change options: https://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
Rsync hangs after a while when tunneling from A-B-C
Dear Rsyncians, I'm trying to Rsync my windowsXP-pc A and C. There is a firewall in between A and C, but we have a port open on a linux-machine B to access C from A (and vica versa) via B. When I now run my Rsync scripts in cygwin: # ___ #!/bin/bash # Command to synchronize (only update) two computers based on RSYNC FOLDER_SOURCE=/cygdrive/d/scripts FOLDER_TARGET=/cygdrive/g/stefaanlh/scripts PC_SOURCE=ip of pc-A PC_TARGET=ip of pc-C echo Synchronizing of SOURCE with TARGET rsync -auvvvz --timeout=999 -e ssh [EMAIL PROTECTED] ssh $FOLDER_SOURCE/ $PC_TARGET:$FOLDER_TARGET echo Synchronizing of TARGET with SOURCE rsync -auvvvz --timeout=999 -e ssh [EMAIL PROTECTED] ssh $PC_TARGET:$FOLDER_TARGET/ $FOLDER_SOURCE echo Done # ___ Rsync hangs unexplainable after a while (+-a minute). You can see the end of my log-file below my email. It looks like a time-out because, when I restart the program after it hangs it continues where it stopped before and afterwards hangs again after a minute. Is there anyone with advice on how to solve this?

Re: RSync + SSH tunneling through firewall
Haai Andrzej, The problem is solved. When I double checked the ssh-b file I realized I had to change the linux commands to cygwin commands. >From that moment all commands (like date, hostname...) worked on the C-host So with the key authentification and the following ssh-b script: #!/bin/bash ssh [EMAIL PROTECTED] ssh "$@" the rsync command works: rsync -auv -e ~/ssh-b /cygdrive/driveletter/localfolder/ host_C:/cygdrive/driveletter/remotefolder and I don't get the pseudo terminal warning anymore. Whenever you are in Belgium, I owe you a beer or something else to drink. Thanx a lot for all the help. Kind regards, Stef Andrzej Filip wrote: Stefaan Lhermitte wrote: I did. I can now connect via SSH as wel from A - B as from B - C. I also resolved the problem of not being able to connect to C. I restarted the sshd and now it works. The problem now stays with the rsync. I used: rsync -auv -e ~/ssh-b /cygdrive/driveletter/localfolder/ computer-C:/cygdrive/driveletter/remotefolder/ I get no errors but only the following output: Pseudo-terminal will not be allocated because stdin is not a terminal. Unfortunately it does not rsynchronize, since no files are copied. 1) Do you get computer-C shell prompt when you execute "~/ssh-b computer-C" ? [ you may ignore "pseudo terminal warning in *this* test ] 2) What do you get when you execute "~/ssh-b computer-C date" ?

Re: RSync + SSH tunneling through firewall
Yessos, very cool. It works even with rsync -auv -e ssh [EMAIL PROTECTED] ssh src_folder host_C:sdt_dir Sometimes solutions can be very simple... Unfortunartely all open positions for email postmasters are just filled in. I did my best to convince my boss, you were better, but it didn't work.:) Thanx again!

RSync + SSH tunneling through firewall
Dear RSYNCians, I'm trying to rsync my labtop pc (let's assume A-computer) with my desktop pc (let's assume C-computer) through our firewall. In between there is one computer (let's assume B-computer) that has an open port, so I theoretically could connect via a tunnel. I checked the SSH- website and internet and so on but did not find an answer that works. I tried the solution I found on the net: When I run ssh -v -L 873:C-computer:873 [EMAIL PROTECTED] and get connected to B-computer without any problems. When I subsequently run in a new window: rsync -v /cygdrive/d/folder/ 127.0.0.1:: cygdrive/folder I get the following error: Connection reset by peer. In the tunneling window teh following error appears: administrativetly prohibited: open failed I'm kind of new in the SSH-RSYNC world and don't know how to solve the problem. I assume it is an SSH problem since the problem persist when I run: ssh [EMAIL PROTECTED] -p 873. Thanx for your help in advance, Stef -- To unsubscribe or change options: http://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
Re: RSync + SSH tunneling through firewall
Nope, I cannot telnet port 873. I tried "telnet C-computer" and "telnet C-computer 873" but command give the error: Connection refused. On the other hand, the SSH command from B-computer to C-computer works does give connection without any problems.
