What command would you use to read about the sync system call (not the sync command)? How would you read a local man page for sync that was kept in the /usr/local/share/man?
I have about 50 servers with at least 200 GB free on each host. I need close to 10 TB of continuous shared storage between almost half of the servers for a new app I building.
I was looking into buying a storage device but was wonder if I could get any use out of the free space on all the servers, grouping all of the free storage from the hosts into one reduduant storage array.
I have a UBUNTU server 10.04 LTS with 3 network interfaces (eth0,1,2) which eth0 is connected to my lan and others connected to two different ISPs , I would like to know is there any way to share bandwidth of this two ISP for my LAN , I mean for example if eth1 has X MB bandwidth and eth2 has Y MB bandwidth my clients those who use download manager for downloading file from internet has X+Y MB download and upload bandwidth.I do not want just limiting each user or service to use one of those interfaces I want to share them for all to increasing my internet bandwidth
We are running SLES 11 where an iscsi tape library is attached. To load the tape in a slot we are using for instance the command #mtx -f /dev/sg1 load 2 which is doing very well. But after a server's reboot the device name of the loader is now /dev/sg4 or /dev/sg5 I mean it is dynamic. Is there any way to have a fixed device name for all times?
In my RHEL 5.4 system after each reboot the device file of tape changer (IBM-3310 Tape library) is changing.So i am not able to give a fixed device file in backup software.
I have been using an LTO-5 Ultrium-3000 tape drive connected to an ATTO HBA without problem. I can control the tape drive using "mt -f /dev/nst0" and have been able to make successful backups using cpio, tar, and dump/restore. I followed some instructions on the web about how to install the HPE Library and Tape Tools application (version 4.21) which relies on conversion of a rpm to a deb file. The software seems to have been installed correctly and runs. However the hardware scan function does not recognize my tape drive. The following is suggested in the user manual if the tape device is not recognized by the software under Linux:
1. Login as root. 2. Edit the following file: vi /etc/modules.conf 3. Add the following line as appropriate: add options scsi_mod max_scsi_luns=128 4. Reboot the computer.
The problem is I don't have an /etc/modules.conf and am not sure exactly which file would be equivalent? If this is even the correct solution.
My tape drive is controllable and functions well using "mt -f /dev/nst0 status" so it seems to be a matter of LT&T software to detect the tape drive.
At the risk of providing too much info here some, possibly relevant, output from lshw

I am looking at getting a DLT drive for my network; however, I have never used the tar command with a tape drive. What happens if the data is larger then 1 tape? Does the tar application automatically span tapes or do I need to use switches so it spans multipule tapes? Right now my Full backup will take 2 or 3 tapes.
After removing GDM, XFCE4, and the crap-load of dependencies that came with it, something must have gone wrong. I can not place items nor delete items any more. How do I fix this problem of mine? I'm using KDE at the moment.
Code:
Could not make folder /home/theif519/.local/share/Trash
Deletion of files is necessary. I have installed libtrash hoping it'd work, but it didn't, I even did chmod 755 like it suggested I do. What do I do?
I have dell poweredge 830 server with tape drive and RHEL 4 running on it....the issue i am facing is,i am unable to insert the tape as i had ejected the tape forcefully from it....
i tried to do a listing of the contents backedup on tape and it got struck in middle throwing below error,
/dev/st0:device input/output error. after which i was unable to eject the tape using mt -f /dev/st0 rewoffl
i removed the tape by holding the eject button and now when i try to insert another tape, it's unable to take the tape in to tape drive...
I've tried doing all except reeboting the server, can any one help me out in this issue, hope the blow information may help in debugging the issue... code....
I am using mount.cifs to mount a remote samba share (both client and server are Ubuntu server 8.04) like this:mount.cifs //sambaserver/samba /mountpath -o credentials=/path/.credentials,uid=someuser,gid=1000.I mounted a user from local system with username and password with mount.cifs but the problem is that the user is part of multiple groups on the remote system and with mount.cifs I can only specify one gid. Is there a way to specify all the gids that the remote user has?
Mount the remote samba with multiple groups on the local system?Browse the mount from 1) with the terminal since I want to pass some files from samba as arguments to local programs.which runs through gvfs; but the newer gnome does not write to disk the ~/.gvfs anymore so I can't browse it in terminal. And the last solution would be NFS but that means that I have to synchronize the uids and gids on the local system with the ones from the server.
I have a Dell PowerEdge 1650 server with 3 NICs in it. I am trying to use one NIC (eth0) to connect to the internet, the second NIC (eth1) to share the internet connection to a LAN, and the third NIC (eth2) to connect to the LAN.
It is running Ubuntu server 8.10
The problem that I'm having is that NetworkManager (version 0.7.0) keeps setting eth2 as the default connection, and then I don't get any internet at all from the server.
My main goal is to be able to share files from the server to computers on the LAN. The secondary goal is to have a virtual machine hosting a Halo server, connected through eth2, so that it can host LAN games. But that is a secondary goal after I get the connections to work.
I've been looking around and finding other people who have done bits and pieces of this, but not the whole thing. I had been hoping to simply use the NetworkManger, but I don't mind editing config files.
Also I can't seem to find any good instructions on editing the /etc/network/interfaces file. The man file is incomplete, and everything seems to point back to the man file.
Has anybody been able to get NX (Nomachine) running on Fedora 10 configured using a shadow session of the local desktop (X11-local). I am experiencing some kind or cookie creation error, perhaps privilege related?
FYI. Normal unix-kde sessions work fine (e.g. Giant on Box) and shadow sessions of an existing unix-kde session works fine too. A shadow session of the local display is a bust.
Here's the error log:
Code: NX> 203 NXSSH running with pid: 4076 NX> 285 Enabling check on switch command NX> 285 Enabling skip of SSH config files NX> 285 Setting the preferred NX options
I have some typical issue while trying to connect to my root or other users from my terminal.
like su - asking for password and after that it displyed a message like $su -
Password: could not open session
I tried connect using ssh then I am getting the following $ssh root@localhost Last login: Sun Nov 1 14:13:45 2009 from localhost Connection to localhost closed.
Background: Before this happended, I was tryied modify sshd_config in /etc/ssh/ folder to allow passwords less than 2 words.
I have a slack 64 13.1 box, that I want to be able to control the monitor of from my laptop. Here's the scenario: I can already control the music remotely via X forwarding banshee to my laptop (banshee shows up on the laptop and music comes out on the desktop). Now I want to be able to open a movie on the desktop's display via the laptop.
Now googling this comes up with solutions for X forwarding, but I don't want it to forward X I want it to display on the desktop.
We have RHEL4 loaded on the server and our tape drive is not working.While taking the backup on the tape using the command tar cvf /dev/nst0 * the system is creating a tar file by the name of nst0 in /dev directory and no backup is being taken on the tape .Please provide solution.
i have centos 5.9 running on my server and i have to take backup of my entire data from the different server.This one I want to make it as backup server. I need few informations about the tap drive
1.Which tape drive is good also compatible with Linux (centos ), pls send me the link 2.How to take backup into tape drive , good if you send any doc. 3. Any backup software which is kind of opensource
I'm running nxfree to log into my remote xubuntu PC from my local xubuntu laptop since the X protocol was broken.Has been working fine. Recently upgraded from Lucid 32bit to Maverick 64bit Xubuntu.Now when I run nxclient in fullscreen mode, if I minimize the window (or just log out) my local display does not return.I'm left with just the background colour. The windows are still there but not visible. For example I can:* randomly right-click and a menu pertaining to the invisible window appears;* press alt-tab and cycle through the windows but activating one does not display it (it remains invisible);* press ALT-F and bring up the current active (but invisible) application file menu;Basically I press ALT-F and ALT-TAB and close everything and then log out and log back in to restore the windows/panels.
we have a server that runs a backup (cron job) at 9:15 every night. When I log on in the morning I have mail message that gives me a long list of all the files that were backed up the night before. For a couple of weeks now, the mail message gives me an empty list. Yet, when I run the same job manually from a #prompt, it runs. I am not able to run this job with cron in the daytime because too many users are in it. I wanted to browse the tape to see if the backup is really failing to copy the files or if they are on the tape and the mail message is bogus.
Since the backkup was done with cpio instead of tar, I'm not sure if I can browse the tape with restore -i anyway.What would be the best way to browse the tape on /dev/rmt/1 without actually restoring anything ?This is an ancient DGUX system, not Linux, and I'm not a unix expert I just inherited this server recently, but a lot of things are very similar to Linux and it looked like this might be a good place to ask.
We have been using an Ultrium LTO-2 tape drive to perform backups of certain information from our file server. Recently, the data that we are backing up has grown too large to fit on the tapes in their 200GB uncompressed capacity. I have been looking around for a way to enable the compression in the drive, but I haven't found much. I am not using any backup software, so I'm not sure if I'll even be able to. I write the tape using a simple 'tar' command, so there aren't a whole lot of options to be set. Is there a way that I can enable the drive's compression, or would I be better off running the tar command with the gzip or bzip flags?
I didn't know if I should have posted this in newbie, hardware, or server. I haven't used tape drives in Linux previously; however I'm trying to figure out how to enable an LTO-4 tape drives built in encryption. Im not that concerned with secure key management, I am looking to just being able to load a key into the drive and get the tape to encrypt. Im for a simple command, but I dont even know where to start. If it varies by device, its an HP Ultrium 4 (1760).
I have a server with an old version of Fedora on it, Fedora 7, I know its old and that I should have upgraded it. But I haven't I plan on doing it now but I ran into a hardware failure and had to switch to a different set of hardware. I tried going into rescue mode using the fedora 7 install disc, but st0 for tape drives was not available. So I tried using the newest fedora distro, Fedora 13, installation disc and st0 is still not available on there. How to do a restore from tape?
Does anyone know of any existing software to aid in this task? We already offer backed-up data storage to our users, but no means of say arching original data sets for long term storage(NIH, etc rules). Something that could be user initiated, where they login into the archive server, tell it I want such and such files archives, and on its own it takes those files and gives them to a tape library(drive+robot).
