Ubuntu Networking :: Unison Not Connecting Via Ssh?
Jun 8, 2011
I'm having a little trouble getting unison to work on Kubuntu and can't figure out why.I have two machines. One is a dinky little box that I'm using for version control and as a file server. It has an IP address of 192.168.1.5. My other machine is a laptop with an ip address assigned via DHCP. I can ssh from the laptop to the dinky box with no problems. However, in unison, I've set up a profile to sync /home/will with ssh://will@192.168.1.5/WillHomeSync. However, when I try to connect, it just hangs on the "Contacting Server..." window and does nothing. How do I even go about starting to troubleshoot this?

I'm trying to set up a synchronization with unison and iwatch to (more or less) instantly sync files upon change in a directory tree. iwatch calls unison like this:
Code:
unison /home/foo/vhosts/foo/my_vhost/bar.html ssh://server.tld//srv/www/vhostsfoo/bar.html -batch -terse -ui text -owner -group I would expect unison to sync all files between the two servers. However, that is not the case. Everything works fine as long as the files are only created/changed/whatever on the server running unison. If a file is created on the server that unison is synchronizing to, it gets deleted the next time unison is called.
For example:
Code:
on the host running unison:
$ cd /home/foo/vhosts/foo/my_vhost
$ touch foo.bar
-- sshing to remote host ---
$ ssh remote.com
[code]....
$ unison /home/foo/vhosts/foo/my_vhost/foo.bar ssh://remote.com//srv/www/vhosts/foo/foo.bar -batch -terse -ui text -owner -groupI expected that both files get synchronized - foo.bar from the unison server to remote.com and hello_world.html from remote.com to the server running unison. Instead, hello_world.html gets deleted.
I've been working a while on this and don't seem to be able to figure it out. Maybe it's only an argument to unison to rectify it but I couldn't find anything adequate in the manpage either.

I just installed Ubuntu 9.10 and its great. However when I connect to the internet at home it shows that the connection has been established but I still cant connect to the internet. My flatmates are all able to connect. However, I am able to connect from work both wirelessly and through an ethernet cable.

i set up ssh and unison on my windows machine and i am trying to do a sync on my ubuntu machine to windows. i am running into some issues.
certain paths give me the following error: Error: The path Music/Xxxx is ambiguous (i.e., the name of this path or one of its ancestors is the same, modulo capitalization, as another path in a case-sensitive filesystem, and you are synchronizing this filesystem with a case-insensitive filesystem. When i search for Xxxx on my ubuntu system i only see it in that one Music/Xxxx location.

There's an error when I try to connect to an SSH server with Unison.It says 'Received unexpected header from the server: expected "Unison 2.32" but received "myuser@myhostname" ...'I use Unison for Windows as client to connect to Ubuntu Unison SSH server.Of course It is connected well from localhost to localhost with SSH,but not from a client outside.

Unison-gtk on a new 11.04 machine talking to a 10.10 machine hangs. It never connects to the rsync over ssh to the destination 10.10 machine.

My system consists of a laptop running Ubuntu 9.10, a network drive (Samba share formatted fat32 the only option) and a desktop PC running Windows XP. For several weeks have been trying to set-up Unison to synchronise files between my laptop and a network drive with only limited success. I mount the network drive locally with:
sudo mount -t cifs //netdrive/store /home/gm/NAS -o guest,rw,iocharset=utf8,file_mode=0777,dir_mode=07 77.
Then in Unison (graphical interface),
root 1 is: /home/gm/Shared_Docs
root 2 is: /home/gm/NAS/HomeBackup/Shared_Docs_Backup
After clicking the �OK� button, Unison searches for changes files and I click �Go�.
An error is then produced, a sample of which would be:
�Error in renaming /home/gm/NAS/HomeBackup/Shared_Docs_Backup/.unison.Our-inv.xlsx.f3e8034159989f9de7081f9154319a2b.unison.t mp to /home/gm/NAS/HomeBackup/Shared_Docs_Backup/Our-inv.xlsx:
Input/output error [rename(/home/gm/NAS/HomeBackup/Shared_Docs_Backup/.unison.Our-inv.xlsx.f3e8034159989f9de7081f9154319a2b.unison.t mp)]�
If all files in the destination directory (root 2) are first deleted, all files are copied correctly without errors so, I think the problem may be caused by permissions where Unison is unable to overwrite the original file. I know formatting the network drive fat32 is probably making the matter worse, unfortunately I have no alternative.

I have a home server that houses all my files accessible over SSHFS. I am looking for a tool that can bidirectionally sync the Documents Folder on the server with the one on my netbook, so that I can keep my work-flow up to date on both regularly. (the directory in question contains mostly MSOffice files and a few PDFs. It is about 1.5GB in size, most of which never changes.
From what Ive read all the apps I mention will do the trick. Which would you recommend I use and why? Note: I am leaning towards Unison, as it seems to have good SSH support which is important (as I often have to synchronize away from my LAN). Do the other three have any speed/feature advantages which I would be missing in Unison?

I've just installed Unison. I created the default profile, selecting one of my subdirectories as the source. That done, the GUI disappeared, although a unison-2.32.52- process remained running. I can start another GUI session and, regardless of if I kill the old process, I can only choose my profile before the GUI disappears again. There is no opportunity to do anything else useful, such as selecting a destination directory.

I need a program to run on Ubuntu that must be easily set up to do a series of different cloning operations at specific times between the USB drives on a single Ubunu pc, depending on the day of the week." So on Monday folder B is forced to match folder A, Tuesday C forced to equal D ... and on Sunday a whole bunch of these clonings happen. This must all run unattended (at 2am) and be robust with no "what do you want to do next messages" or having the whole thing give up if there is a problem with one file. Though I do need a log of success or failure. Windows programs that do this stuff are FolderClone and GoodSync. I looked at Unison and Rsync and one or two others, but none appeared set up to do what I need, or to be excessively complex / general. I don't need something that can sync two copies, or over internet ....

Been thinking about a new backup-strategy for my family and me. In our house is an Ubuntu Server (10.10) and NAS (Zyxel NSA210). Now I thought I'd create a Cron Tab entry on all machines which will sync specific folders automatically to either the NAS or a specific backup drive in the server. So now the question is: "How do I do that without seriously compromising each family members privacy by making their backed up files available to everyone in the house?" So in essence I'd like to sync/back up the files to a password protected share for each family member. But this process should still be done automatically every few minutes or so without them having to enter any password at all as their specific password is stored locally.

I need a good bi-directional sync. tool like unison, that would work properly over ssh and allow manual decisions and merging if both sides (local&remote) contain changes. unison meets most of my needs, the only drawback is the compatibility - it needs to be installed on both sides, and with the same version. Nowadays it's a bit of a problem, if you have say OS11.3 on one node, SL3 on the other and a MacOS on the third. In my view one only needs the ssh connection, all the rest of the file analysis should be done by the local software. Anyone knows such a tool?

Just a minor question, but I notice with aircrack when it lists networks, it does not list the encryption type of each network.
Which seems fair enough, as you can use Kismet, however on my machine when I end kismet and the server, the monitor interface is not removed and I cannot remove it manually, which screws with aircrack.
SO, is kismet needed to view encryption types of networks, and if so how do you use it peacefully in unison with aircrack?

What follows is actually a copy of my yesterday post on users mailing list, which so far had no response at all. I hope I'll have more luck here.I have 3 PCs running Hardy, Karmic, and Fedora 12, with Firefox on each of them: v. 3.0.18 on Hardy and v. 3.5.8 on both Karmic and Fedora.I created "shared" profile on each system and synchronize them using Unison. Ubuntu 8.04 is a base system for synchronization.The synchronization itself works just fine on all 3 systems. No functionality problems on either of Ubuntu's.In Fedora however I'm having a problem. While using "shared" profile I can save neither a web page nor a download (unless I use some of add-on' as described below).
If either Save Page As... or Save Link As... menu items are selected the requests are simply ignored with no response from FF. However using Download Them All add-on does the job. Equally Scrapbook add-on allows me to save/capture pages.
The default profile works as expected. I thought SELinux is on the way but disabling it (for a test sake) did not changed things. All permissions in "shared" profile directory to me look OK.I'm new to Fedora and cannot figure it out myself, need you help, folks.

I have unison running on both my laptop and desktop, both use Ubuntu 10.04 (AMD64), I have my unison script set up to copy new files, but when it have 2 files already in place I have to manually tell it how to deal with it (either copy laptop->desktop or visa-versa). I would prefer to just run unison and click go, or possibly have an icon on the desktop I can click to automatically run it. how to set it in the script file to copy the newest file over the older file, whether it be laptop -> desktop or desktop -> laptop?
I have it set up so I can do work on my desktop machine, then when I want to leave my desk to work elsewhere, I run unison on the laptop and synchronize my Firefox bookmarks, emails and schoolwork so I can continue from where I left off and when I get back I run unison again to synchronize all my changes back to the desktop.

I am looking to implement a file server, in a small office we have users in 3 different continents, Europe(Ireland), USA and Asia(China) with 3 main offices, 2 in Ireland and 1 in China We currently have 1 file server in Europe synched to another in Asia office using unison Our USA staff and roadwarriors connect over vpn to the fileserver in Ireland Users indicate that access the files in the fileserver from outside the office is prohibitively slow....its served by a 12Mb/2Mb broadband line, which is used for all office traffic
We have hosted servers where we could setup a file server as an alternative to setting up in the offices... Can anyone recommend a good, free/opensource

I just want to use Internet Connection Sharing (ICS) to connect to the internet. I have done a massive amount of troubleshooting, but some of it seems to contradict itself, and the only two things that I know for sure are that it used to work, and that my Ethernet cable is not the problem. When I use Terminal utilities like ifup and dhclient it seems that it can not determine IP information, but when I try to put it in manually, the "Apply" button grays out right after I finish typing it in. When I try to connect normally, in KDE or GNOME, the icon acts like it's connecting, then instead of having the connected icon, I receive a notification that "the network has been disconnected", and it goes back to the disconnected icon.
Oh, and by the way, I know that I could probably find a workaround, but I have limited resources, and this used to work. The Linux is a Dell desktop with Fedora 12 and the Windows is a Windows 7 HP laptop.EDIT: I hope that I didn't mess something up, but I accidentally used system-network-config to try putting in the IP address there, and ended up changing it back to the original settings, but the computer is now calling it Auto Ethernet in the taskbar icon, although sudo iwconfig in the terminal still calls it eth0.

Forgive me if this has been answered, but searches have been un-fruitful. I recently built a 64 bit Ubuntu 10.10 pc. It is sitting right next to my Windows 7 Premium 64 bit machine. They can't see each other. I disabled Homegroup on my network. Now, when I try to access Ubuntu from Windows, I am prompted for a username and password. Both systems have the SAME UW and PW. It doesn't connect.When I go from Ubuntu to connect to Windows, I am prompted or Workgroup passwords.

I have often connected to my machine's remotely through ssh. Today I noticed that when I connect, the "last login" IP seems a little weird to me. I'm on my home network, so I connect directly with the IP of the computer within the router. But after the IP I get this XXX.XX.X.XXX.dedicated.neoviatelecom.com.br What is the neoviatelecom part? Is that normal? I don't remember ever seeing that there before. If I connect a couple of times from my win7 laptop (through cygwin) I get the correct IP address, but followed with the other part. If I connect with my other desktop (running Karmi 9.10) I get the same neoviatelecom thing as above.

I recently installed the latest version of Kubuntu in a dual boot system with Windows XP on a Dell laptop. The dell laptop has a broadcom wireless device, and I was able to set up the driver and get wireless working. Then I booted into windows XP to make a whole bunch of updates/driver installations, and when I booted back into Kubuntu it would not connect to the wireless network. I am pretty sure the device is still active, because it picks up on the wireless networks in the area. But KWallet does not open to ask for my password on booting. Something is not set right, but I can't tell what.

Situation: I can access Ubuntu from Windows XP but not XP from Ubuntu. When I try to access XP from Ubuntu I get message "Unable to mount location Failed to retrieve share list from server"
In System/Administration/Network Tools using Network device: Loopback Interface (lo) I can ping the IP address of the XP machine. Also, using Network device: Ethernet Interface (eth0) I can ping the XP by using its computer name.
In System/Preferences/Network Connections it shows under the Wired tab: Auto eth0 never used

A group I'm working with recently got new netbooks with Ubuntu Netbook Edition 10.04 and some AT&T LaptopConnect (3G) cards. When I hook them into the usb port, the cards light begins blinking, but nothing shows up to indicate ubuntu has recognized the new card, nor am I able to connect to the internet. My searches for help have indicated no one else has had any difficulty with this and that the card usually pops up and installs some drivers automatically or something.
I'm not sure at the moment the model of the 3G card other than very new, but I can check on that in a bit. The netbooks are HP Mini 210s.
