General :: FTP Or Rsync Transfer Drops Network Connection
Apr 23, 2011
I'm using Scientific Linux on a laptop, connecting to a debian server on my LAN via a basic BT HomeHub router. When starting a file transfer with ftp or rsync from the laptop my connection is dropped, every time, after a couple of seconds. I have to reset my network adaptor and restart my network manager (wicd in this case) in order to get network connectivity back. I had a very similar problem before - [URL]. On this occasion my workaround was to replace NetworkManager with yast. I am now using SL though so no yast available, and I am not using NetworkManager any more anyway.
i am trying to transfer a file from my live linux machine to remote linux machine it is a mail server and single .tar.gz file include all data. but during transfer it stop working. how can i work and trouble shooot the matter. is there any better way then this to transfer huge 14 gb file over network,vpn,wan transfer. the speed is 1mbps,rest of the file it copy it.

This is a recent problem, and I can't pinpoint any change/upgrade that would cause this. Rsync transfer from Client to Server: sent 11756196 bytes received 1032741 bytes 138258.78 bytes/sec total size is 144333466390 speedup is 11285.81 Pinging back and forth from each machine is fine. No Ifconfig errors Client, but Server has RX packet errors.
i am using mobile broadband to connect with network after i connecting mb.it drops it's connection for every 10 minutes.i need to restart to reconnect it.it is happening in kde.
I can connect to the wireless at my school, but the connection drops frequently and regularly. Network Manager still shows bars indicating the network strength and shows that it's connected to the network in the dropdown. Selecting the network again causes it to indicate that it disconnects and reconnects. At this point I have wireless until the connection drops again. Possibly relevant details: This is the Purdue PAL2.0 network, which can be tricky to connect to, particularly for Linux users. It's a hidden network using WPA2 and PEAP. My computer is a Dell Inspiron 1420n laptop, circa August 2007.
If transfer all files under a directory by rsync, what is the order that rsync determines to transfer the files one by one?At first it looked like rsync transfers files in alphabetical order, but later I found rsync skipped some files in the first sweep through the alphabetic order, and then went back to transfer files that were skipped in the first time and this time still in alphabetic order.
I have a big iso image which is currently being downloaded by a torrent client with space-reservation turned on: that means, file size is not changing while some chunks in in (4 Mib) are constantly changing because of a download.
At 90% download I do the initial rsync to save time later:
$ rsync -Ph DVD.iso /media/another-hdd/ sending incremental file list DVD.iso
[Code]....
Then, when the file's fully downloaded, I rsync again:
total size is 2.60G speedup is 1.00
Speedup=1 says delta-transfer was not used, although 90% of the file has not changed, target dir is on another FS and copying takes several minutes. Why doen't it try to speedup the transfer?! How can I force rsync to use delta-transfer?
I am using centOS 5.My internet connection drops at irregular intervals and it restores only after reboot the system.Even if i deactivate and re-activate it using Newtwork cofiguration utility,It shows its active but it cannot open any page.
I've restarted a server a couple times, and during the boot process pings respond when it brings up eth0, but then when i get to the command line login screen, the pings die. once i log in and do a ./network start the pings respond again, so i'm guessing its dying or not set to start automatically maybe? What should I check?
I have to transfer large amounts of data (>80 GB) over ssh using rsync. Everything is working fine, but the DSL connection where the backup data is sent from will drop once every 24h for up to 3 minutes (switching providers is not an option).
How do I:
Automatically restart the transfer when the connection is back up? Make sure there are not by accident two rsync commands running at the same time?
I have a feeling that there is no answer to this issue but I'll try.I have an rsync server running. If I rename a folder, rsync will re-transfer all the files under that folder. Does anyone know if there's any automated way around this ?
I am unable to transfer file using rsync. I have installed rsync and ssh package.. When I try to transfer file , its giving an error rsync -v -e ssh a usw3tvx@lalqau40:ssh:lalqau40: Name or service not knownrsync: connection unexpectedly closed (0 bytes received so far) [sender]rsync error: error in rsync protocol data stream (code 12) at io.c(463) [sender=2.6.8]I tried with simple format... nothing works...Even I couldnt ssh with hostname. However I can connect with Ip address... I
I wrote a script to wake up my windows machine and do an rsync backup of some of my files. I wanted to make this command a accessible through local bin so I made it executable. However the problem is that when I copies files is copies them with root permissions and i can edit or delete them. How can I set the files so they transfer with the proper permissions for my Ubuntu user?
Code: #!/bin/bash # Description: This script first wakes up the client machine and syncs the appropriate folders. # Finally the script shuts down the client if it was off to begin with. if [ "$(whoami)" != "root" ]; then echo "Permission Denied" exit 1 fi .....
I need to create a script that will compare the differences between two folders and then to copy only the updated and new files only to another directory. I know I need to use rsync here, I can write scripts so really it not how to create a script it is how do I accomplish the transfer of only new or changes files between two folders to a new file. Do I need to link these two folders first and then use the "--compare-dest" switch.
I have two computers: one is connected with router by wi-fi and another is connected with router by lan. How I can optimal organize connection between two computers with Ubuntu 10.04 for transfer files? What Do I do? Can I share some folders,
I'm looking for a most possible, secure solution to transfer data using rsync over Internet between 2 linux server. I have 3 option: SSH, IPSEC and Kerberos. Which one in your opinion should be most secure solution?
I have ubuntu 9.10 server installed, I am connecting with putty over ssh 22. but after a while (about 20-30 mins) the connection drops. and I have to connect again. is there any configuration for that?
Recently, Putty keeps intermittently freezing and locking me out of the system (i.e. I can't stop the session and I can't re-login via ssh again until I've gone to the machine and pressed "reset").
So far, it mostly occurs when opening a file in VIM, but it does sometimes occur when using tab to auto-fill a file or directory name at the command prompt.
Every now and again my internet drops out for no apparent reason. I try dhcpcd -k eth0/dhcpcd eth0 and nothing. I try modprobe -r <driver> modprobe <driver> dhcpcd blah blah and nothing. /etc/rc.d/rc.inet1/2/d restart. Nothing. The only thing that works is rebooting my system. how to reset my connection without rebooting?
I often have to transfer huge data over our LAN from one computer to another. The size of the files varies and can be somewhere from 2 GB to 50GB or more! The only accepted connection protocol between machines are ssh; and rsync and scp are the only options available for copying over network (unison is not installed). I usually use rsync with "-z" option to copy over network. if "rsync -z" is faster than "scp" for data transfer?
I got a new low power file server (Atom 330 with ion), but didn't enjoy it since.
I installed Ubuntu server 9.10 64bit.
I randomly experience connection drops. As I'm installing and testing, there are lots of ssh windows open, I transfer much data using scp from my laptop to the server (all connected to wired lan).
Connection drops are as follows: ssh windows terminate with "connection reset by peer", but not always all the ssh windows terminate. For example, I edited a mediatomb config using nano, that stayed open even with scp and all other ssh windows cut.
I also have apache2 installed because I'm running urd (a usenet download tool). It seems that when I start the deamon, connection drops. So I killed apache2 to try out but that didn't solve the problem.
I left ping run all the time, and the server is pinging back all the time, which is really strange as I thought that a connection drop means the whole network interface going down.
When this drop occurs, I have to wait 2 minutes until I can ssh back into the server.
I also installed mediatomb, but it isn't really fun to stream a video to my ps3 as it always hangs after 5 to 10 minutes.
I've had a computer running Ubuntu connected to my TV for a few weeks now, but as of yesterday, I can't get it to keep a connection to the Internet. Everything works well for an hour or so after a reboot, but then no WAN connections work. When this happens, no sites load in Firefox or Chrome, I can't ping Google, I can't SSH to the box from work, and none of the pages I have running on apache load from remote computers. However, all local area connections seem to work fine. SSH from within my LAN takes much longer than usual, but it does still connect.
Something really fuŃked-up is going on with my machine... whenever I try to update my repositories (regardless of if it's by Synaptic, Ubuntu Software Center or terminal via sudo apt-get update), my PC loses connection, and I need to reset my WLAN twice to make it work.It's in a specific part where it happens...
Hello, I've installed OpenSwan with xl2tpd on my server, and set it up for roadwarriors connecting using certificates.
My server is Debian 5.0.8, I am running xl2tpd 1.2.0, and Openswan IPsec 2.4.12, my clients are all Windows, and I am testing my setup on a Windows 7 client.
I have no problem connecting to the server, but after some time the connection drops. I removed the idle option from the ppp config but it does not make any difference.
Even when I create constant traffic with ping -t the connection drops also.
I have no problems reconnecting right away.
I have been hacking at this for a couple of days, reading every post I can find, but I have not found a solution to my problem.
I'm having problems with my mobile connection. This has been working fine for months, but in the past few days it has connected OK, I've been able to transfer data, but after 30s the connection closes. Setup is Acer AA1 with F12 connecting via bluetooth to Nokia 3110c on O2.
So to try and figure out what's happening I put the bluetooth dongle in my desktop PC, also running F12, made a connection and again it dropped out after 30s. Then I fired up windows on the AA1 and made a connection using the same dongle, this time it held up OK. This leads me to think that something has changed recently in F12 to upset it.
In order to get my shares working I first have to connect to the windows shares from the Ubuntu machine. Then I can connect to the Samba shares from the windows machine. If I don't continue to use the shares. It'll drop the connection and I have to unmount the windows shares and start the process over. The wireless network still shows as being connected but I get an error on the windows machine if I try to connect. I've Googled this and it appears to be a Windows problem. I know this is a ubuntu forum but thought I'd ask for any info. I believe that this is also what is giving me shared printer issues as well.
I'm having a really strange problem with my wifi connection on my laptop. The ethernet connection works fine and so does the wifi connection - as long as I sit within one meters range from my router! As soon as I take the laptop further away the connection drops. The router is still being found by network-manager and the signal is just below 100%, but when I try to establish a connection it fails.
I'm sitting here on a fresh Ubuntu 10.04 install, and I had exactly the same problem with 9.10. That time I went through a lot of different procedures, and in some strange way the problem was solved. I haven't been that lucky this time though, I've tried reinstalling network-manager, using ndiswrapper, installing the wireless backports package, tried all kinds of drivers.. nothing works.
There shouldn't be any problem with the connection itself; I've had a perfect connection downstairs but now I can't even connect if I stand two metres from the router! Has anyone experienced anything like this and managed to fix it? My wireless card is Atheros AR2413. This is an example from daemon.log
I have an Acer Aspire One ZG5. 160GB HD, 1GB RAM model. I've done a fresh install and an upgrade of 10.04 and have the same problem both ways. I am able to connect to my wireless connection but it is dropped after about 5 minutes and have to wait about the same time to reconnect. I've had to roll back to 9.10 being that I use the netbook for work and school on a daily basis.
I have had this issue for a while on my centos 5.4 dedicated server with 1and1. If I reboot my system, my connection starts and then drops in about 10 seconds after the system has booted.I connected through the serial console and noticed there was only one thing that seemed suspicious while booting. named could not start for some reason. So my question is - are these 2 problems related? If not, what could be the reason for my connection to drop?At the moment the only way of getting the connection back up is by running dhclient. This works until the next reboot.
I could not find a solution to this problem anywhere. I use a ubuntu server to play (stream) mp3s and movies to other computers on my network. It works most of the time, but sometimes in the middle of a movie or a song it will drop/hiccup--saying it is "not reachable". I am not overtasking the server at all, and merely playing an mp3 that takes up less than 10% of the bandwidth, yet it drops it for a split second.
I have a WRT160N router (DD-WRT of course) with 4 clients connected (2 of which are wired). The ubuntu server is connected via ethernet and all machines have the same issue. It can't be the router because another Windows machine works just fine for streaming these files. I just can't understand how it can lose connection for a second or so. It may just be the file-system or some service that is hiccuping, but I have no idea...
