General :: Best Setup For My Situation?
May 27, 2010
I've had a fair share of experience with Unix, but am humble and didn't see a better place to put this.
Bear with me here:
I am in a situation where I will be without owning a computer for a while. I have a 16GB SDHC which uses very little space for music/photos/game-saves and I wanted to use it along with a USB card reader to boot into a Live USB distro. I've tested with Ubuntu flavors and things work great. But after doing some reading, I found that the constant read and write is hard on any flash drive (not to my surprise).
I have decided to use a LiveCD instead, and see if I can allow persistence on my USB/SDHC setup instead. I absolutely need to virtualize a Windows XP machine within the Linux distro and be able to save some stuff.
For starters, what is the best distro for me? I'll be using it mostly for programming and the shell, so a fancy desktop isn't really needed (but man does Ubuntu look nice). I'm just making sure I can install and run programs from an SDHC in the way that I want.

Server (LVM):
500GB
320GB
I want to install a new 500GB and remove the 320GB, of course moving the data on the 320GB to the new 500GB. I have an external 1TB in enclosure that I can plug in to move the data over, but how do I move only the data on the 320GB to it?? I found this [URL]. But that is only to move the data to a new replacement disk, but my external is only temporary to move the data from the 320GB until I remove it+install 500GB, then move the data back. Not enough space on the 500GB already on server to move everything from 320GB to it, just in case that seemed the obvious thing to do.

Situation is that there are two users on a Linux server- say A and B.A has been operating a shell script that in turn makes use of and exe file.The script and exe both are owned by user A.My problem is that I want user B to make use of the script and exe in exactly the same way user A does.So I have set suid bit of the script, exe and all the library files that the exe uses.But the exe is still not executing from user B.I did a man of chmod on Linux server and it gave an indication that SUID is disabled on new Linux servers.Now the question is, is there any other command that can perform the same task as SUID did on Unix.

I had serious problem with recording from tv via tvcard. My new distribution is Fedora 13 and the recording program is mencoder. The tvcard is Pinacle 110i. I recorded without problem when ripping from dvd, but when I tried to record from tv, I becam the answer: no /dev/dsp ... cannot open the demuxer. First I thinked that the problem cam from alsa settings, so I searched a while about this. And I didn't found alsaconf, like in Mandriva.So, after searching, I found the solution.
1. As root, issue the command
#modprobe saa7134 card=77 tuner=54
#modprobe saa7134-alsa

I need to install ubuntu or edubuntu (preferably) on an older computer (256 ram) whose cd rom is shot, but the USB ports work! The family has 2 kids and the parents are very computer illiterate and know NO English. The kids' future is dependent on learning English. The grandfather is illiterate in his language! They are not down and out people, but they could use some help, if you know what I mean! I do have an external DVDRW drive and 2 computers where Ubuntu Maverick and Lucid have been installed. I will be about 300 km from them to give support. I have 2 days Monday to Wednesday next week to install Ubuntu or edubuntu.
I read on the internet 3 solutions, one of them offering a USB fix, which I am not 100% clear on: [URL] I do not know how to program and am far more comfortable around a GUI, even though I sometimes venture off using the terminal (albeit, copying and pasting codes that other provides and that often I only get half the meaning of). The USB stick option seems to be one of the best solution at this time because I have tested it in the past! The computer has suddenly crashed (I had installed Windows in a multiple user/password mode), but one of the kids (older) was using games from friends' usbs (maybe full of virii)! Maybe the crash is a hardware crash as surges are common in the area. (I will be able to check for that using some kind of software if I can boot the comp.) After installing Ubuntu succesfully on two more recent computers already, I think Ubuntu or edubuntu might be the best solution for this situation. I am also 300 KM from being able to help out these people!
I have a few questions at this time. If the option of basically using one computer's image (ubuntu Maverick) that I have installed with all the packages that come with it (solution 1) is a viable one, how am I going to deal with the difference in hardware between the two computers. DOn't they need "drivers" and packages related to these specific components? Could I use the external dvd drive? If so, how can I get the old computer to recognize it. Assuming I can make it work again, would I need to download (beforehand) the windows drivers/files needed? Install them which might help if I want to use it to install the ISO image. I am not thinking about a dual boot since space is an issue and windows is a bad option anyway (virii).

I did a NMAP on a 10.4 desktop system. Found tcp wrapper on my system with an open port. Again I do not run a server. etc/host-deny and etc/host-allow contain no active elements. I know tcp wrapper as a great tool to secure a server. Closing the port with ufw gives no result, tcp wrapper still show up.

alrighty, long story short, I screwed up. I had installed a copy of ubuntu 9.1 to my sda1 partition and a copy of windows 7 to sda2 and it worked pretty well, but after needing to change the partitions around, I deleted sda1 and did a wubi install. I forgot to adjust the mbr before deleting the ubuntu install and my live CD is still running ubuntu 9.1 (think that's grub 1.5) and I can't update the live CD, as my only functioning OS is currently running off it. I suspect, therefore, that the mbr is still pointing to a now non-existant partition to find the boot files. So, in short, how do I use my current live CD to allow me to boot into windows in this situation? my current partition table is sda2: windows 7/wubi, sda1: media/backups

I expected more from ubuntu 10.4 with regards to printing with exact size photos and with poor auto colour printing but the situation remains unchanged! for instance .. the photo size configurations for ubuntu/fspot/gimp and others are not compatible with my printers (HP and Brother) .. here in Europe a typical standard size photo (10x15inches or 150x100mm are not even on the Ubuntu listing? I have tried all listed possibilities including "custom" (which does not seem to ever work correctly?)and the result at best is photos with uneven boarders or at worse my printer goes a bit crazy with much wasted photo paper and expensive ink ...even photos selected for "no boarders" still produces photos with the self same uneven boarders.
I have tried pretty much everything over time following advice in this forum and including using HPlip and updating drivers required for my Brother printer but the root problem seemingly lies with the Ubunto photo size setup listing. Working with Ubuntu over the years I have found that it can do pretty much everything that Windows can do except for this dam ongoing photo quality and configuration problem.

I've been all afternoon trying to install Ubuntu Lucid on my fakeRAID 0 configured (2) HDDs and am unable to set GRUB up. The fake RAID setup is provided by Intel Matrix Storage Manager, it is correctly enabled and the BIOS is also correctly set up -- in fact, I've managed to install Windows 7 with no significant hitch. After struggling with partioning the drives (had to follow advice I found on a very helpful guide online [0]), creating the filesystems AND getting Ubuntu's installer to actually do what it is supposed to do, I now cannot seem to set GRUB up. My system, as it stands, is unbootable at all; via live CD only.
This is how the RAID0 dev is partitioned:
Code:
# fdisk -l /dev/mapper/isw_ecdeiihbfi_Volume0
Disk /dev/mapper/isw_ecdeiihbfi_Volume0: 1000.2 GB, 1000210694144 bytes
255 heads, 63 sectors/track, 121602 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 131072 bytes / 262144 bytes
Disk identifier: 0x6634b2b5 .....

I ended up setting up a basic linux file server as a pdc for that office. Our main office is a windows 2000 ads domain. The two offices are connected with a vpn. I only have two users at the new location so I simply have the linux and samba usernames/passwords setup manually. I would like to know if it is possible to setup a domain trust between the two sites so I don't have to create a username/password in the remote site for every user at the main office to access. I did some searching but came up empty.

So I didn't notice when I setup my CentOS 5.5 server that I left / as RAID 0 on md1. All the rest are RAID 1. Is there a way I can modify the array to RAID 1 without a risk of data loss? I'm glad I caught this before I setup any other services. I've only setup smb so far...

Im trying to setup multiple domU through the default bridge setup. I am able to access only one of them through the network at a time. If you ping one of the domU it works perfectly but you cannot ping any of the others until you stop pinging the one and even then it takes a bit before you can. Ive looked around for a while and seen similar problems but nothing ever seems quite the same. Im probably missing something really stupid. Or is this the way the bridge is supposed to behave? Do i need to use a routed virtual network?

I want to setup a FAI server for which I was looking for the best method of mirroring the Debian Lenny. I want to setup a local mirror with the best method available for mirroring. If it is ftpsync, please provide me some best ways of doing it. I tried ftpsync mirroring but that was not getting properly working due to insufficient I want this mirror to be accessible in my FAI setup so that I can start the installation on multiple machines and start the updates and package installation to be done from the same local mirror.

Im trying to set up my workflow to a terminal-based setup, so that accessing my computer through SSH will provide many of the things I need and use right off the bat. I have Mutt working great with my GMail account, so that's good. I do have a question though. Using the application Calcurse (featured on Lifehacker a few days ago, [URL] I am at a loss to figure out how to interface with Google Calendar. Is there a trick that Im missing, or does anyone know of another terminal app that plays better with Google Calendar?
Also, I was looking for a 'Digital Clock', essentially, again, a terminal/text based large print clock; similar to the one in the lower left corner on the attached pic. I was looking for a telnet server from the Atomic Clock, but no such luck so far.....

Here is a thought experiment:
1. Copy vmlinuz and initrd.img from isolinux subdir into /boot
2. Adjust grub.conf to boot to that kernel
3. Reboot to setup
4. Format /boot (actually '/' ) during "fresh install"
5. Proceed with the installation-over-network
I see two possible outcomes:
1. The setup fails to reformat the drive, because it is "in use" by boot kernel
2. The partition is not "in use" and the installation succeeds
Why? Old cluster with broken CD-drives, lacking USB, and no separate /boot partition.

With new installs of openSuse 11.4 I've hit a printer problem. I can run hp-setup (or hp-toolbox) for the wireless Officejet j6410 and it is recognised. The right driver is selected. Then when I choose add printer it all falls over with the error message: error: Printer queue setup failed. Could not connect to CUPS Server Is user added to "lp" group(s) error: Fax queue setup failed. Please restart CUPS and try again.
The user is added to the lp group. I have this problem with my 64 bit desktop and 32 bit laptop installs of 11.4, it all worked perfectly in 11.2. I've used the Cups web interface to set up the printer now and can print from both machines, but I would prefer to use the hp-toolbox, which has several convenient features. Where do I go from here?

I have been looking online and trying to install a VPN or TOR in Ubuntu. I have the packages for this from Synaptic Package Manager. I am trying to follow instructions from the Tor site, and have even done the Google thing.
I just can not make it work. I can make it work in Windows on the same computer using VirtualBox, so my router is not blocking the ports.

I am booting a new Xen kernel and it all goes fine up until some point during the boot process when the machine reboots without warning. Unfortunately, I don't see errors flash up just before that happens. Is there a way of booting the machine with a working kernel and looking at a log of the previous boot or something? What I didn't notice is that there is actually an error on the screen. It just flashes up very quickly before the reboot. The error is related to not being able to mount the root filesystem because there is something wrong with my grub configuration.
A normal entry in grub.cfg looks like this:
menuentry 'Ubuntu, with Linux 2.6.32-33-server' --class ubuntu --class gnu-linux --class gnu --class os {
recordfail
insmod ext2
set root='(hd0,1)' .....
I added the following in /etc/grub.d/40_default
menuentry 'Xen 4 with Linux 2.6.32.45-xen' --class ubuntu --class gnu-linux --class gnu --class os --class xen {
recordfail
insmod ext2
set root='(hd0,1)' .....
But it's not working for some reason. I also tried the 20_linux_xen script. Unfortunately that's not working.
See these errors:
Found linux image: /boot/vmlinuz-2.6.32.45-xen
Found initrd image: /boot/initrd.img-2.6.32.45-xen
Found linux image: /boot/vmlinuz-2.6.32-33-server
Found initrd image: /boot/initrd.img-2.6.32-33-server
/etc/grub.d/20_linux_xen: 57: uses_abstraction: not found
Found linux image: /boot/vmlinuz-2.6.32.45-xen
Found initrd image: /boot/initrd.img-2.6.32.45-xen
/etc/grub.d/20_linux_xen: 156: gettext_printf: not found
Gettext is installed. I'm on ubuntu 10.04 LTS. The error flashed up on boot is something like "please insert a correct root=boot kernel option..." Why is this so hard and why are there so many different examples of grub2 xen? some put /boot in front some just /. I tried putting /boot in front but that didn't help. Also some have --set=root uuid and yet all my other working entries just have --set uuid. Is this something to do with a different grub2 version?

I have been contemplating switching to Linux for some time now, frankly because I'm tired of the blue screens and viruses, the slow speeds, low customization, new versions of programs coming out after years of waiting, high costs/no sharing. As for Apple, I'm not a fan of Steve Jobs going from share-ware to locked down apps and frankly I despise the whole Apple company for that and its high prices. my first HP ever crashed so coming in is a new Dell with details to follow on it - this particular Dell doesn't fit with my habit of getting everything thats the newest thing out, but its close enough to what I had and was a "fast track" item, meaning built and ready to ship. Also, always owned Dells in the past with no problems.
I use my computer for movies, music, internet, e-mail, the occasional spreadsheet and word document as well as games that perk my interest every once in a while. I heard Ubuntu would be good, with Wine to be able to run the occasional Windows based program correctly. I was looking at a dual setup which I would switch to a single set-up if I became extremely comfortable with Linux.

I've been asked to look into moving the contents of 1 linux server which has samba, php, mysql, apache and some other bits installed, to a brand new server which currently only has the os. Is there an easy way of doing this by copying the files/directories straight over or would we need to build all the software from fresh again on the new box? They are both on different IPs so I'm guessing I'd need to update some configs and if I can avoid taking the current box offline then that would also be useful. I'm fairly limited in my linux knowledge.
