Ubuntu Networking :: Mounting File System Accessed By SSH Tunnel?

Apr 23, 2011

I really like being able to mount remote file systems using the Places > Connect to Server ... tool on Ubuntu 10.10 -- it makes transferring files a breeze.

Unfortunately, the only way to access a particular server at work (call it Server A), is by first SSHing into an intermediate (Server B), which is the only one with a public ip.

My process for transferring files from Server A is currently:

myComputer $ ssh serverB
serverB $ ssh serverA
serverA $ scp file to serverB; exit
serverB $ scp file to myComputer

Needless to say, this gets tiring, and multiple transfers are slow.

Is there a way to mount serverA directly on my computer (by tunnelling through serverB in the background)? Failing that, how about using sftp?

Ubuntu Servers :: Mounting A NFS Share Through SSH Tunnel

Jan 12, 2010

Hi, I have a server at my home which is a Ubuntu 9.1 which is setup as a NFS server using NFS v3. I am also using DYN DNS to access my home server remotely from another location using SSH. Everything works good, I can sucessfully log in to my server from my laptop via SSH, however my problem mounting my NFS share which consists of appx. 300 mp3 files. My question is:

1 How Do I Tunnel a NFS share through a SSH tunnel?

2 Is there any other configuration? needed to be done to the router?

3 is there anything needed to be configured to the server or my laptop?

4 Manual mounts is fine for me I don't care about automounting.

I just want to be able to mount the NFS share via the SSH Tunnel and play my music and access other files from my server.I just need the steps to set up this connection.

Ubuntu :: Mounting Second Drive Within File System?

Jun 9, 2011

I have two hard drives in my desktop, a 250GB and 500GB.

The first drive has the swap and / the second drive is just sat there having to be mounted before use. I have a half remembered thought that the second drive could be given a mount point within the file system. I have often partitioned drives so that / is septate to /home but not over different phisical drives. I wouldn't want the 500GB to be /home because a large chunk of the 250GB would not normally be used.

What I would like is to have the first drive set 20GB / the rest to /home. Then the 500GB set to /home/data so it would apear within the home directory or even better /home/user/data as I'm the only user of the computer.

Ubuntu :: General Error Mounting File System

Apr 13, 2011

I have a dual boot Xp and Ubuntu 10.10.

Recently I was downloading some upgrades in Ubuntu and unfortunately the power to the system got off.

Thereafter on booting it comes to the Grub menu and I'm able to select the OS from the list but if I choose Ubuntu it comes up with a message "General error mounting file system" and the terminal is activated. However, if XP is selected it boots with no issues.

/dev/sda6 is ubuntu installation
/dev/sda7 is swap partition

I went through lot of threads over the net and tried fsck, e2fsck and other variations of that command but at the end all I get the message as

it says sda6 is clean but for sda7 it says :

Superblock invalid trying backup blocks.... Bad magic number in super-block while trying to open /dev/sda7 at the end it suggests "u might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device>"

refering some threads here I tried my luck with live CD and the command : sudo e2fsck -C0 -p -f -v /dev/sda7

CentOS 5 :: Mounting Windows File System?

Jun 2, 2009

I have a dual boot system (CentOS and Windows XP Pro). The computer has 2 disks with the operating systems on sda. My data files are on the 2nd disk (sdb I think). I would like to be able to access the data files on sdb from CentOS. I tried issuing the Linux command:mount -oro -t ntfs /dev/sdb1 /mnt/winbut CentOS tells me that ntfs is not a file system it recognizes. Even if I leave out the -t ntfs I get the same message. Any ideas on how I can get access to the Windows files while in the CentOS boot?. I got the idea for the above mount command from the book: Fedora 10 and Red Hat Enterprise Linux Bible byCristopher Negus.

Debian :: Mounting An FTP Address To My File System Automatically During Boot?

Apr 7, 2010

I'm having difficulties mounting an FTP address to my file system automatically during boot. After a bit of research I have discovered a package called curlftpfs, I've installed this package using aptitude and I had no errors.

I've successfully mounted an FTP address manually using curlftpfs at the command line and proved to myself that this is working as it should...However, I can't get this to mount automatically and I am receiving the following error during boot when I try and mount it through /etc/fstab...

Error connecting to ftp: Failed to connect to (IP address of server): Network is unreachable

My research indicates this package should be able to do this.

I'm still a learner when it comes to Linux, but could this be because TCP/IP services are not started at the time of mounting the filesystems? I've tried a continuous ping at this computer whilst it is booting and I don't get a response until after /etc/fstab has been processed. If this is the reason, can I start them these processes earlier?

Another option would be to have a script/command run when the computer boots, but prior to MySQL loading. If this is possible, it would also satisfy my problems.

General :: Mounting An Ext3 File System Destroys Superblocks?

Jun 27, 2010

I have an image of an ext3 file system done with dd. I know that the file system is corrupted but I want to try to recover some files. Whatever I dd it again to the original partition or assign the dd image to a loop device, that's what happens:

- dumpe2fs -h gives me a valid ext3 superblock.

- as I try to mount the device read only, it fails with a bad magic number error.

- executing dumpe2fs -h again gives bad magic number error.

- trying debugfs or fsck with backup superblocks fails the same way.

For me it seems that in spite of mounting the device as read-only, mount command do something wrong with the superblock as before the mount the superblock is correct and it's there.

OpenSUSE Install :: Mounting Or Checking A Partial Ext4 File System?

Sep 3, 2011

If you have a contiguous partial piece of an ext4 file system (assuming it's perfectly clean), starting from the beginning of the partition, is there any way to check it, or to mount it to get the files whose parents, inodes and data are all completely contained inside?

Have (or maybe had) a very large 11TB RAID 6 array, filled with a single large ext4 partition. Something strange happened when a single drive failed and the array ended up failing 13 out of the 11 drives. I had trouble getting the array restarted, and got to the point where I exhausted all of the options I considered completely safe. I considered a few things that may have worked, but mdadm doesn't seem to have a definite "do not change anything" option. So I decided the only way to be absolutely safe would be to clone the disks before proceeding - then I realized how much time that would take and sent the drives off to a recovery service so they could image them and check it out.

Before doing so, I copied the first 2GB from each disk. I XORd the images from the working drives to reconstruct the data chunks that were on the failed disk, manually assembled the chunks, and am very confident that I have 22GB of "correct" data in a single file. The parity and Q syndromes all matched (with RAID 6 you can still check with only 1 missing device). I've learned the fine details of ext4 from [URL], and have looked at lots of raw data from the reconstructed partition, and it all looks good. The recovery company says that they're not finding many inodes, but I found a lot of them, exactly where they're supposed to be. I tried to mount and e2fsk, but both processes seem to be extremely unhappy that the device size doesn't match the size implied by the file system geometry.

I considered hacking the superblock to manually reduce the size, but I figure that wouldn't work because there would then be more group descriptor blocks than it would expect after the superblocks. I might try doing that and compensating by incrementing the "reserve block count" to compensate. Alternatively, if there is some way to make the file appear to be the expected size with nothing but zeroes after the end of the actual data, maybe I could mount it and not get any errors until I cause the kernel to read past the true end of the file.

General :: Ext4 New File System Mounting Compatibility With The Older Ext3 Type?

Sep 7, 2009

How well is the ext4 new file system mounting compatibility with the older ext3 previous Linux installations ? I refer to Ubuntu 9.04 and the new Fedora 11 which have the option to install with the ext4 file format. Will it be better if I install with the older ext3, so that I will be able to mount all other Linux from each other in a multi-boot system ?

Server :: Mounting Ext3 File System As Ext2 On Slackware With Custom Build Kernel?

May 16, 2010

I just rebuild the kernel for slackware 13, everything works, but root file system which is ext3 is mounted as ext2. Normally I've build ext3, ext4 and so on as modules, not in the kernel... but if I do this, then the kernel mounts the file system as ext2, which is build in the kernel. I also modified rc.modules so I can make sure that ext3,ext4,jbd are loaded, but it doesnt work.

Ubuntu Networking :: Limiting When The Internet Can Be Accessed

Nov 30, 2010

I have a teenage daughter that understands Ubuntu, but not so much the terminal, and she does not know the superuser password. Unfortunately, she regularly goes on the Internet during the nighttime and in the early morning. What I am attempting to do is prevent anyone from going onto the Internet during the night (11 PM - 5:30 AM) unless they know the superuser password or a fair bit about the terminal.

I have already tried some commands, however all of them can be bypassed by restarting the computer. ex. sudo ifconfig eth0 down

For additional information on my Internet:

My Internet connection is relatively slow, so I would prefer if the solution does not hinder it any further. It is slow because there is no high-speed in my area, and I am forced to use Xplorenet -> "Fixed Wireless". I do not have a router.

Ubuntu Networking :: Vpn - No Other Addresses Can Be Accessed Before Login

Jan 28, 2011

In order to get internet access at my school I have to log into a vpn. No other addresses can be accessed before login. With XP the login is authenticated through the browser (IE and Firefox supported) and run by a juniper network connect applet.

Now when I try to do this in firefox in Ubuntu it tells me that I'm not allowed to login. So I started doing a little research and found out that I should be able to authenticate with VPNC. Trouble is I can't get internet to install anything. Which means I have to download the packages in XP and reboot into Ubuntu. And every time I hit a snag I have to reboot into XP to look up what I need to do. So what I'm wondering is if there is some work around that will get me logged in (maybe through the browser authentication?) so that I can work through issues in one os instead of two?

Ubuntu Networking :: Samba Share Accessed As Wrong User?

Apr 4, 2011

I've had a Samba share set up for awhile now on my Ubuntu 10.04 server. Now I'm trying to create separate shares for separate users. When I started, I was logging in from my Windows box where I was Tony, and the only user on my 'nix box was htpc. I had the majority of my file permissions as open.

Now, I've created new users on the server, including Tony. But when I open a Samba share from my Windows computer, it does so as htpc. This is not a setting I ever put anywhere. I don't care about specific user names, but I want to have a folder that only I can access from my Windows box, and for someone else to have a folder only they can access from their Windows box.

OpenSUSE Hardware :: Mounting An Edirol R-09HR Digital Audio Recorder - VFS: "Can't Find A Valid FAT File System"

Apr 2, 2010

I'm having problems mounting an Edirol R-09HR digital audio recorder (as a USB drive, to read the recording files) on a system running openSUSE 11.2. fdisk or other partitioning tools recognize the device as a "W95 FAT32" drive with a filesystem code of 0b, apparently. I was under the impression that mounting this as a vfat file system should work, but the mount command dies complaining "FAT: bogus number of reserved sectors" and "VFS: Can't find a valid FAT file system." This happens even with a freshly formatted card in the recorder. The device mounts properly with Windows XP systems and late-model Ubuntu/Kubuntu systems, Any clews as to what I'm doing wrong here?

Networking :: Mounting Permissions Error / Mounting A Windows Host?

May 28, 2009

I am having permissions errors every time I try to mount a windows host. I have a linux server and all the windows computers can see that computer and its files, but we wanted to start backing up the linux machine to one of our other computers. so I tried to mount one of the computers. here is the sequence of events:

Code:
$mount -t cifs //192.168.1.194/Admin$ /mnt/Anita-comp
password: (I have no password so I left it blank)
Mount error (13): Permission Denied
I tried all sorts of passwords we use around the office and none of them worked.

I then decided to try mounting one of our other computers. this one looked like it worked fine. no error messages at all. (I left password blank) so I look in my filesystem and the mounted drive is not in the /mnt/Anita-comp file. What gives?
