General :: Multiple Machines: Share Data Using NFS / HTTP / FTP?
Apr 4, 2011
I have a network of 20 machines, all running Ubuntu 10.04.
Each machine has about 200[GB] of data that I'd like to share with all other 19 machines for READ ONLY PURPOSES. The reading should be done at the FASTEST POSSIBLE WAY.
A friend told me to look into setting up HTTP / FTP. Is it indeed the optimal way to share data between the machines (better than NFS)? if so, how do I go about it?
UPDATE: Just to clarify, all I want is to be able (from within machine X) to access one of machine Ys files and LOAD IT INTO MEMORY. all of the files are of uniform size (500 [KB]). Which method is fastest (SAMBA / NFS / HTTP / FTP)?

Two machines connected via LAN Older machine is running RedHat 3 Kernel 2.4.21-50.ELsmp on i686 Newer machine is at a current level of SUSE Linux. Newer machine has a DVD drive. Here's the question. Is it possible to, remotely, mount the DVD device to the older machine? If so, can it be used to install software packages?

Im new to the forum and fairly new to Linux as well. my apologies if this is posted in the wrong section. My problem is How can you search for a file in multiple machines (like a server farm) ? For example i log onto machine num1 and want to search for a file named "xxx.yyy" which may be in one of 4 machnies. What i do right now is manually log into each machine and run the find command. However i have heard that it is possible to do it via a couple of simple commands. I have looked into pssh and cssh as well as ssh tunneling (along with public key authentication to stop the machines requesting a password every time i log in) and unfortunately i was unable to find an answer.

Two machines, each running Ubuntu 10.10. Desktop is wired to the router, and laptop is wireless. Printer is an HP Photosmart C4400 All in One series, and is connected to the desktop via USB.Prints OK from desktop. I have CUPS set up on both machines, and the laptop can see the printer. Desktop firewall allows CUPS in on port 631. Printer properties are set to enabled and shared Desktop is set to publish printers, and laptop is set to show printers from other systems. Fine until I try to print from laptop, when print job is shown as sent, but printer remains idle. Another thing is that on the laptop, the "enabled" setting drops off. I think this must be a configuration issue, but cannot find an answer anywhere. File sharing using Nautilus works fine.

Personnally up until now I've been using either NTFS or a ext3 fs driver from Windows. I wonder if there's a better way. Probably NAS is the best, but not really practical with a laptop.

I remember there was a command that would allow me to pipe data to an app and the use the | operator to pipe it into yet another app.
foo fooArg | Iforget app1 | app2
I forget what this command is but it pipes the data from foo into app1 and app2.

I just installed ubuntu 10.04 x64. I have installed it and set it up the way I like on my server, however I now have 3 terminals and a laptop to set it up on the exact same way. As a result Id like some advice on what can and cant be done and how. Preferably I am looking to use programs with GUIs. Thing the style of ubuntu one, software manager etc, not really too into the command line, or conf editing unless there is no other option.
1. I installed all the software from software centre I like. Now I need the same software on the other computers. I know mint has mintbackup where it just exports and imports a list if installed software. I am looking for an ubuntu equivalent.
2. Firefox and Thunderbird add-ons. I install like 20 firefox and thunderbird add ons. sometimes I can't even keep track of them. There must be a way to sync them so that each computer I install ubuntu on I can simply import the list of mozilla add ons and have it auto download them.
3. Mail Contacts and Calender Syncing. I need to sync between my 3 ubuntu machines and my windows mobile 6.5 device for calender, email/phone/name contact lists. Email is taken care of by imap, but lightnings calender isnt and neither are the contacts. If I input a contact on my phone I want it to sync to the other computers I use.
4. Ubuntu one. I have /storage/workfolder in my root directory on my personal server. I want to be able to work on documents at work on my laptop and sync them so that when I get home, they are synced on the server without causing overwrite changes etc.
5. Desktop settings, icon themes, preferences from ubuntu tweak etc. I know this one is a bit more of a long shot, but it takes 20 minutes each computer, to set up the little maximize minimize buttons on the other side, set up cairo dock the way I like, install the icon theme and backgrounds I like. isnt there a way to back this up so it doesnt have to be done each time or so I can make my other computers the same?

I'm running kernel release 2.6.26-2-686 on a i686 and are trying to share files between my machine and some Windows 95/98 machines. When I enter smb://ip_number/share_name in Nautilus, it works. I can browse the files. When I try the same with smbclient or smbmount, it complains.
smbclient -I=ip_number -L=//server/share gives cli_rpc_pipe_open: cli_nt_create failed on pipe srvsvc to machine tf_calibration. Error was ERRSRV - ERRerror (Non-specific error code.)

utility to let me automatically apply shell commands I type to a list of given remote machines? I'm configuring and maintaining multiple servers all running Fedora 12 and I want them to have exactly the same configuration. I also need to check out code from subversion onto these machines; the same code from the same location into the same directory. I know I could use ssh to run each command individually for each machine, but is there a tool that will make this much easier?

I've got an external hard drive with one large data partition on it. I also have four computers to connect it to (individually, not at the same time). Three machines are running Slackware and one is running Ubuntu 9.10. I need to be able to just plug the drive into whichever machine, mount it (preferably to the same location each time) and not have to worry about user permissions and such. Do I just chmod 777 all the files and folders or is there a better method for different 'users' to access the same partition? And how about mounting to the same location each time?
Now the second part of my question I'm pretty sure I'm not able to do but just in case..... is there any way to encrypt the information safely and make it compatible with a Windows XP machine?

I've got a Netbox NT330i [URL]
Ubuntu 10.04 (server) installed with a few minor issues, but is generally in fine shape.
I installed apache2 and the whole lamp stack ready to do some Drupal work.
I noticed a logo.png wasn't loading. Apache logs thought it was serving it fine (200 responses)
It wasn't displaying because it was being corrupted.
I hunted for some reason, stripped back apache2, removed it, installed it bare.
Same problem.
I tried nginx. Same problem.
I've compared pdfs transfered from the webservers and I can see it every-so-often clumps of corrupt data.
Also, wget on the same box gets the files without corruption.
SSH works fine. No corruption. But medium size SFTP transfers can take a while - I presume because it's having to resend corrupted data until the checksums add up.
I then tried using wlan0, which seems to work fine, so it's just the ethernet port corrupting data.
From lspci, the eth0 is an AR8131 rev c0

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 manged to get a samba server up and running to share with my windows machines. But i still want more. My main goal is to be able to share my movies. I have a laptop hooked to my flat screen with 3TB's of external drives, thats whats acting as my server. I have ubuntu desktop installed because i use it to play movies also.
I'm looking to set up something that is a little faster than samba (yes i no trying to share through USB 2.0 external drives and a wifi connection isn't going to be real fast no matter what) but i want to be able to access my server remotely. like maybe FTP? but what i'm asking here is what protocol should i use and what programs? i was thinking gadmin-proftpd and then filezilla to access?

I'm having some trouble mounting a Samba share on my two Ubuntu machines. The Samba share is setup so that all files are readable and writable by everyone (it's only accessible via the local network). When I create a new folder on the share with either of my Ubuntu machines, the folder becomes non-writable by anyone ie. I can't place anything into the folder. I'm using the following command to mount the share:
[Code].....
I think the problem is with the way I'm mounting the share on my Ubuntu machines. If I go to the share using smb://192.168.1.160 in a file browser, I can create new folders which are readable and writable by everyone. But, if I create the new folder where it's mounted at /mnt/backup, no-one can modify or change it.
