Ubuntu Servers :: Back Up Windows PC As It Connects To The Network
Mar 22, 2011
I have a little home server with Ubuntu 10.10, actually it is already backing up my web hosting daily via a cron.daily script.. But I would like to do the same with my Windows laptop, which would it be the best way to do so?
since the Ubuntu pc is (almost) always turned on it would be no profit to have it mount the Win PC at startup, indeed I could have a cron.hourly script to check if the Laptop is connected to the network and to back it up once a day, thus by checking a small text file with written the date of the last backup BTW how do I check if the Win PC is connected to the network? How do I mount it via samba? Do you suggest to backup stuff simply moving files, via tar (as I already do with my web host) or with rsync?

I've recenelty setup a backup server using Ubuntu server 10.4 x64.
I'm currently attempting to get the server to connect to windows vista and windows 7 shares on the network.
When running the command
Code:
smbclient \\hazard-pc\test
a prompt for a password appears, I enter nothing and am then presented with. I am not using passwords on the windows shares.
Code:
smb: >
If I attempt to list the directory using ls then I get the following error:
Code:
smb: > ls
NT_STATUS_ACCESS_DENIED listing *
57138 blocks of size 1048576. 32044 blocks available
smb: >
I've looked on google and on here and have not been able to find anything that works. I also don't have any xp machines to test with either.
I discovered this issue whilst trying to configure the backuppc service using smb.

I need to back up a Windows computer to a Ubuntu server across the internet. It needs to be secure as I'm transferring business data. I have been searching high and low and am only coming up with sporadic, half solutions.

I have a system running a very basic LTS install (10.04). Ubuntu has been setup with very little additional packages. No GUI. Once it's booted to a prompt for the first time I add the following packages,
cups cupsys ssh pi memtester nfs-common
aptitude safe-upgrade
At this time I don't have additional information on exactly what packages are installed. I did not perform the installs myself. I will update this thread when I get more details from my IT counterpart on how the system was setup.
This is used for a headless(no monitor, no keyboard) system running some custom applications.
Here are two problems.
1. If I plug into an ethernet network after I boot, the network never connects. I need to reboot with the network connected in order to get an IP. What is the service to "auto connect" to a network?
2. I have a network printer configured on lpd called myprinter. If I am connected to the network when I boot, I can print to this printer just fine using:
Code:
However, If I boot disconnected from the network and print to myprinter, the jobs obviously cannot print. They get spooled. Using 'lpstat -t' I can see that the spooled print jobs are assigned a job number and that myprinter is trying to connect. I shutdown, reconnect my ethernet network and boot up. All my printer configuration is blown away.
/etc/cups/printers.conf has been wiped out to look like this:
Code:
My 'good' printer configuration is copied to printers.conf.O
To recover from this, I need to stop cups, copy printers.conf.O to printers.conf, restart cups, and re-setup my network printer.
So, What causes my printers to get wiped out? I've repeated this on 4 systems with the same setup.

I am using a fully up to date openSUSE 11.3 and today, I decided to upgrade my KDE 4.4.4 to Factory. The update went without a hitch, everything continued to work, including all of the items in my workspace.So now I am running KDE 4.4.95 and it looks nice. I like the new System Settings where the advanced tab is gone and everything is presented in a single window.
The only snag I have hit so far, is that Knetworkmanager no longer displays the network that I am connected to when I right click its icon in the tray. The screenshot may make clear what I am talking about.I am currently connected via a wireless network, which nm-tool confirms. However, it is not shown in the Knetworkmanager menu.

All of a sudden, I could not connect to my ubuntu 10.10 server from Windows 7 using vnc this morning. When I open vnc on windows 7 and hit connect, it goes away like its going to connect but never pops up the screen. If I try to connect to my other ubuntu server, it connects quick and I'm able to navigate in it.

I've got a Zotac MAG HD-ND01 with XBMC live installed. This is built on Karmic Koala and runs very nicely through the wired NIC.
I configure the box using a cable. I'm using WPA2-PSK and it is clearly authenticating OK.. It gets an IP address.. the AP shows a connection to the box. My XP laptop connects to the access point OK.. just can't connect to the box via the wireless, and it can't see the network using wireless.
I have followed a number of threads on connecting Atheros 9XXX wireless [URL] but no joy.
Also, can Ubuntu connect to the AP at any speed greater than 54MB? My windows PC connects at 144MB+ . Will ndiswrappers connect at those sorts of speeds?

I recently installed Xubuntu 10.04 on my desktop computer that had a USB wireless adapter DLink DWA-140. I didn't have to install any additional drivers to get it to work. I put in the network SSID and the password and was connected immediately. However, when I try starting firefox it doesn't load any sites. Can anyone help me in approaching this problem. I have a DLink DIR-655 router. If I should gather more information to get this problem solved then please let me know and I will do so.
Edit: Now I am unable to connect to the network. When I click the network icon in the taskbar, my home network is not visible while it is visible under another ubuntu computer I'm running.

I installed Ubuntu 10.04 32-bit on an old desktop (1.5ghz Pentium 4, 20GB hard drive, 768MB RAM) a week or two ago, at the same time that I installed Xubuntu 10.04 on an even lower performance IBM tower server. The server functions perfectly and my other (Windows XP) desktop recognized it from the start, as did the Ubuntu desktop. However, I rearranged a few ethernet cables the other day without turning off the desktops and ever since my Ubuntu machine does not recognize my server, even though all of the devices are connected via ethernet cable to a linksys router and it connects to the internet without a problem. I'm a linux newbie - this is my first move away from Windows - and I don't know where to turn. Far more confusing is the fact that, when I boot from a LiveCD, the network is recognized and I can read/manipulate files on my server without a problem. Oh, and I briefly flirted with OpenSUSE KDE (not as noob-friendly as Ubuntu, so I'm back) and encountered the same problem.
Needless to say, booting from the hard drive is preferable to booting from CD every time

Another issue I'm having, considerably more serious, is my ability to connect to wifi access points with proxies. The story goes, my school has free wifi, but you have to go through their proxies to access the internet (like at McDonald's or Starbucks, where you must 'log in' and accept their usage terms). I can connect, including DHCP, and when I type in any URI I get the redirect posted to Chromium's address bar, but I simply cannot connect to it. This has happened in Ubuntu and Arch, using at least a couple different network management methods (I usually use WICD but I think I started off with networkd). The strange thing (to me) is that my Android phone works just fine, so although I'm not completely familiar with Android on this level, I don't imagine it's the fault of Linux itself. but I'll only be able to experiment with this once a week, on Saturdays (when I have class --gotta do something entertaining).

I'm trying to connect to a Cisco VPN at work from Ubuntu 10.10. On earlier versions, I was able to import the config and get it working. In 10.10, though, the best I've gotten is being able to connect to the VPN, see the welcome message, and have packets sent over the tunnel. I don't receive any packets, though.
The command-line vpnc client connects just fine. I found this bug report: [URL]
The symptoms it describes are exactly what I'm seeing. The apparent solution is to "make sure in your config that LZO Compression is enabled (checked) under Advanced"; however I see neither an option for compression nor an "Advanced" tab, button, or anything on my VPN config in Network Manager.

I just loaded 11.2 & Kde 4.3. Installed both Kinternet and Kppp. My modem is a USR PCI HW modem 2976. Hardware Info shows it connected to /dev/ttyS4. I configured the modem with Yast as modem0. The user access box is checked for Kinternet Both Kppp and and Kinternet will dial out.
The connect response comes back from the ISP and either of the dialers will hang and the dial tone comes back. The firewall is showing modem0 in the External section. Nothing changes if I shut the firewall off.There's nothing in the dmesg I could find. Could this be a pppd permission problem?

I've my OpenSuse installed both on laptop and PC.
The kNetworkManager works well on the laptop both on user account and root account. It connects to my mobile broadband fine.
The problem appeared on my PC. When I log into root account - everything seems to be fine, It connects through knetworkmanager - The cellular connection gets activated, I see X and a heart near "Activated". root account reads my DNS'es from resolv.conf
When I only log into the user account (not as root), the knetworkmanager connects - but as I've checked - it seems that it doesn't use the DNS adresses I've entered in resolv.conf (netconfig_dns_policy is set to "") so I can manually add openDNS to the resolv.conf). It just connects -
I did CHMOD the files resolv.conf and config in sysconfig/network - no luck.
The only way to bypass this is logging to root first - connect there, then switch to user while staying connected... but I think it's an annoying solution.
logs contain this when connecting from user account:
Code:
May 16 10:30:52 jaychyl-1-linux pppd[24965]: Plugin /usr/lib/pppd/2.4.4/nm-pppd-plugin.so loaded.
May 16 10:30:52 jaychyl-1-linux pppd[24965]: pppd 2.4.5 started by root, uid 0
May 16 10:30:52 jaychyl-1-linux pppd[24965]: Using interface ppp0
May 16 10:30:52 jaychyl-1-linux pppd[24965]: Connect: ppp0 <--> /dev/ttyUSB0

I got a little problem with network manager. I got two connections in it, with two different DNS-Servers, because the one of my provider is very slow I surf with opendns, but sometimes that slows down too, so I want to change if necessary. Both connections got the same fixed IP.That worked all fine, until I got my new router (it's a Netgear WGU 624). It's connected by cable and I configured it like the old one. But for some reason instead of connecting to the manually configured connections, my fedora 10 creates a new one "auto eth 0" with a dynamic IP. So every time I boot or switch on from standby my PC connects with this one and I have to manually set it to the right connection. There's no chance to edit or delete it cause those two buttons are grey and won't work. I also tried restarting network manager manually and I also tried starting it with su as root.

When my router switches off... the wifi signals go off... then why the hell ubuntu keeps on connecting to that very wifi like hell and when doesnt connect shows the prompt to manually connect... with the wifi key already filled in... whats the use of saving the key when it has to ask the question from me either to connect or not?? and if its isnt available... just wait when its available.. and for the prompt,i have only option to cancel(because wifi isnt available at that moment if i select connect it again tries to connect like hell..which it cant) and if i cancel it wont auto-connect when wifi does get available! what the heck?
Windows has this done the right way... when the wifi isnt available.. it dissconnects silently.. and when it becomes available connects silently.. why isnt this been done this way in ubuntu??
Ive attached an image..one can see in the image that it says "authentication required by wireless network" when there isnt any.. as router has gone down!
And the second thing i want to report is that there is no way to report this bug from ubuntu... the launchpad.net talks of going through bug reporting process which is done against a definite package... now how does a user know which package would be causing this error?? there should be a more clear process of reporting such bugs to ubuntu team... which a common man using ubuntu( ubuntu says its most user friendly of all distros right?) can report..

Got a laptop with a RTL8187B wlan card, installed opensuse 11.2 on a 50gb partition. Card was detected straight away but only connects when I enter ip addresses manually, DHCP don't work.
When it is connected it always stays at a speed of 1mb/s and it cannot ping my router or anything else.
Me kernel is 2.6.31.8-0.1-desktop
Searched around the forums but no love, tried compat-wireless but it started crying about dependencies. Modprobed it too..

In openSuse I can connect to a wireless network. It says that it is connected, and I can open the router page (http://192.168.1.1/basic.html). But I cannot load any other pages. Nothing else recognizes internet either; I tried using konqueror, YAST and wget with the command line, and none of them could load anything. It is not a router problem or a wireless card problem because both Ubuntu and Kubuntu can connect, from the same computer. I know this is odd because in the only other thread I could find with this issue, it was a different distro and installing openSuse seemed to fix it.
Hardware:
Computer: Yakumo Notebook model 331
Network Card: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
RaLink RT2500 802.11g Cardbus/mini-PCI (rev 01)

I have one pc on which I have installed slackware and samba (fixed IP, mask 255.255.255.0) I have another PC (also XP) which also has fixed IP running XP, and I can connect that to the slackware server easily My third PC connects to the internet and gets its IP address from the Cisco router(?) that provides the IP and mask on boot up.
I tried changing the IP and Mask on the slackware server to match the internet PC (which uses a mask 255.255.254.0) but the PC mask and IP changed on the internet PC I want the PC that connects to the internet to also be able to connect to the slackware server, but I see no need for the slackware server to also connect to the internet - I will mainly use it as a file server When I worked for another company I think the IT department talked about having 2 network cards in the PC that connects to the internet

I know Windows forward and backward but I am so new to linux it's just wrong. I just installed fedora (like 1hr ago) on and old toshiba laptop with a WiFi PC card. Everything seems to work fine except. My Networks connects to my home Wifi network but it will not connect to internet. When it connects the IP address isn't even close to being in the same range as my other laptops and PCs. Like I said I'm new to linux but I'm wanting to learn. Any fixes for this issue? Which linus book is the best one to read for a beginner? Other then not connecting to internet I have no complaints.

I have 3 windows computers and just bought linux server. All of them are currently connected to switch. There is also Wireless AP connected to switch and ADSL router connected to switch (yeah, I know its possible to buy a 3in1 but this was bought piecemeal). ADSL is doing the DHCP and I'm not using any other advanced services.
Now, I want to route everything over the linux server. I got the 3 LAN cards for him (one for wireless, one for LAN and one for ADSL) but when I connect everything this way its not working (surprise surprise). I'm following Linux Advanced Routing & Traffic Control HOWTO but its surprisingly sparse on the topic of network setup and i dont know how to proceed now. Since the server will be a choke point I presume I need to setup DHCP server on him? First question is: can I use same netmask on all of these subnets? Ubuntu DHCP server guide uses both static and DHCP and am not sure if I should also use static on some routes or is it ok to use DHCP on all.
Also, when I was installing ubuntu server only one LAN card was used (eth2) so ifconfig shows only lo and eth2, but when I do ifconfig eth0 up and ifconfig eth1 up it doesnt look like its working. Anyway, hope somebody has some tips to point me in the right direction, primarily DHCP server setup and if I missed any steps...

I am sure there is a nice guide out there somewhere but I cannot find it. My question is: The company I work for has a fully windows environment, servers and clients. The current server is on a Windows 2000 Server and I plan on replacing that. I wish to use Ubuntu server with Joomla for this purpose. This is my first venture into a purely command line interface, although I have played around with Ubuntu desktop in the past. My first question right now is: How do I log onto the Windows Network (active directory) from the ubuntu server. eth0 is reporting a valid internal IP on the network, so its been picked up okay.
Edit: I also want to assign a static internal IP address instead of grabbing from the DHCP. Edit2: Thinking about it, as the ubuntu server and windows server can ping each other do I even need to log into the domain? The server will only be serving web pages.

I cannot browse the samba printers from windows xp professional clients.
I get the following message when trying to access the workgroup:
Code: Example is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.
The list of servers for this workgroup is not currently available
Another strange thing is that if I set the workgroup to EXAMPLE in smb.conf, the workgroup shows up as Example on my windows clients.

Suppose that I am in a private network of computers (say each having ip addresses 192.168.. ). Some of the machines( we have no information regarding their ip, name and no physical access to the servers) in the network are connected to internet and they run an http proxy at some port say 3128. Is there a program which can be run on Windows or Linux which will give me the list of machines(ip addresses and ports if possible) acting as proxy servers?

I have a Compaq Presario CQ60 with Nvidia GeForce 8200M graphics card. When I first installed Windows 7 followed by Karmic in dual boot I could boot into both OS. Now when I try to boot into Windows, it displays the Windows logo and then drops back to the grub menu. It may have started happening after Windows 7 installed updates. I tried reinstalling both Windows and Karmic again and it again worked initially but now Windows no longer boots. Does anyone have any suggestions about what may be causing this or how I can fix the problem without reinstalling?
