I downloaded a file that was 40mb compressed and was almost 700mb when fully extracted. It was inside a .rar file that in turn was inside another .rar file. How can this be done in Ubuntu? Can this also be done with .zip and .7z files?

I am attempting to burn the ISO for Lucid Lynx final onto a 700MB CD. The ISO file is 699MB, but Windows reports that the size on disk is 733MB and thus CD Burner XP refuses to burn the file, stating that it's too large for a CD.
Why this discrepancy on file sizes? I've noticed this with other files as well, suddenly it's a bit of a problem, as you can see!
I have a problem that I can't seem to fix.When I try to transfer a large file lets say 700Mb or so my wireless shuts down and i have to restart my ubuntu computer the other computer is vista.ubuntu is on a wusb54gver4 and vista is going through a wrt54g tm running dd-wrt mega.I have tried every thing i know with no luck.

View 2 Replies View RelatedI try to install a server based on Ubuntu. It will provide many different services as SMTP, IMAP, Jabber, SVN(via Apache),maybe a groupware and some other web applications.I'm looking for a way of authenticating the same set of users (a user essentially has a username, a domain it is belonging to and some passwords) against all of the services.What is the most flexible and elegant way? I need a method which is not too bloated (mysql or ldap would be okay) and is easily applyable to all those services and all services which maybe will come later.
I've read some documentation about sasl, mysql-authentication, ldap-authentication, pam, cyrus, apache, ... and i'm somewhat confused now about the proper way.For now I suspect MySQL to be the best method for that, but i'm not sure about the flexibility for embedding it into all the services.
i need a program in c that forks parent and child process...first parent process sends a message with its id...then child process replies to parent and has to print its id like "My id is"and its parent id like "my parent id is"...

I'm attempting to compress the folder to fit onto my flash drive and am running into problems. Regardless of where I try to put the compression, or what compression algorithm I try, they all give me the error "no such file or directory" and that's all the computer will tell me. Currently I've tried the tar.gz and tar.bz2 algorithms and have tried compressing to //, /home/, and /tmp/.
Am running Ubuntu 10.04
I am new to linux and bash programming. I wrote a simple hello world program.
the code:
#!/bin/bash
echo hello world
but I can not run it by clicking on it.
The only way I ran it is using the terminal even after I check the is it executable box.
Do I need to add any commands to make it execute by just clicking on it?
would anyone know how to solve this problem im having.I copied some files from a normal cd then tried to burn them to another cd the same size but it says the new cd is to small by 24mb which i could`nt workout then, how they fitted on the original.Have the original files been compressed some how?If so how would i do the same to fit them on the new cd?

As far as I know, GNOME can't act like MS or OSX when we wan't to rename a file..you know, when you slightly re click the file name and its ready to be renamed.. instead, I should go right click - context menu - rename to do that.
Is there any setting or apps for these?

I want to make a live CD for ubuntu, but upon getting the .ISO I found that the .ISO was 709MB, and my disc is 700MB. How could I precede in making this live CD? If I use some sort of over burning software, will the live CD work, and please recommend a software to do so if it does indeed work.

View 6 Replies View RelatedI did all the fsck, resize2fs, lvresize, pvresive, parted, etc. stuff and was very careful about what I was doing, but clearly wasn't careful enough. I did backup lv_root to another drive with fsarchiver before I buggered things up, but I can't restore it because, well... I don't know! At this point I'd really just like to wipe the drive I messed up except for /boot and start over but I don't know how to do that when the system seems to think the drive is mounted when it ISN'T.Here's some info:- device is /dev/sdb with sdb1 as /boot and sdb2 a lvm2 volume group containing lv_root and lv_swap -- it was a default Fedora 11 installation that used up the whole drive- i did nothing to /boot and it seems to be fine, grub loads, choosing Fedora 11 shows the logo but quickly becomes a black screen, choosing Fedora 15 Live USB that I originally added from Fedora 11 works just fine (currently trying to fix things from Fedora 15)- i deleted and recreated lv_swap and it still shows up in /dev/vg_box- i shrunk lv_root and the filesystem is within the right size of the lv, which is within the right size of the pv, which is within the right size of the partition, which i made sure i used the right sectors, but lv_root does not show up in /dev/vg_box.
- lvscan says both lv_swap and lv_root are active but lvdisplay says lv_root is "NOT available"- system thinks /dev/sdb2 is mounted even though it ISN'T and can't seem to do ANYTHING to it because of thislvchange -ay /dev/vg_box gives:

I tried to install Lyx today, but because of the massive overhead I decided to install it without its 'recommended' packages. From previous experience some of these packages were just the same font in different sizes that rendered font selected in other word processing applications tiresome as I scrolled through the list.
Code:
apt-get install lyx --no-install-recommends
Only 8mb of disk space was needed! But at a cost.
Although AFAIK as a user that has only spent fives minutes at LYX ( 4 of which gawking at how easy it is to write mathematical symbols in ) the segment that does not work is the 'rendering' where I cannot export as dvi, pdf etc.
When I open a document, I get this error:
Quote:
The layout file requested by this document, article.layout is not usable. This is probably because a LaTeX class or style file required by it is not available. See the Customization documentation for more information. LyX will not be able to produce output.
What packages are absolutely necessary for LyX to work at a bare minimum? My monthly Internet usage is capped, and 700mb is a massive blow to it.
By the way, the documentation it recommends me to read ( 'Customisation' ) contains information applicable to creating new layouts and/or why I do not have someone else's layout that this document requires. It is obvious however that 'article.layout' is a standard component, and is probably inside on of the many recommended packages.
The download of recommended packages is ~ 400mb, but once extracted is ~700mb. That is still a large download for my internet connection currently.
Code:
The following NEW packages will be installed:
dvipng lacheck latex-beamer latex-xcolor libt1-5 lmodern luatex lyx pgf
preview-latex-style prosper ps2eps psutils texlive-base texlive-binaries
texlive-common texlive-doc-base texlive-extra-utils texlive-font-utils

My laptop's been locking up in Linux (Ubuntu, Backtrack, Puppy) periodically for a while now. When it locked up, it was always immune to the magic of SysRq, which I thought might indicate a hardware problem. It became so bad that I had to stop using the laptop.
Today, when I turned it on and tried to boot into Fedora 12, I got the following error (just once, it just locked up at various points during the splash screen after this once):
double fault: 0000 [#1] SMP
last sysfs file:

All the seemingly missing letters were really missing, not my typos.
As you can see, kernel version is 2.6.32.11-99.fc12.x86_64 and my laptop is a Sony Vaio TZ 250N (Core 2 Duo ULV 1.2GHZ). Note that with the other remaining kernels from the updates, nothing ever happened other than the locking up. The core temperatures hover pretty high, about 55-60C peak but this is still below the critical temp. Memtest came up clean when the problem first started happening.

Been using 11.4 for the last few days and I think I might really like it. Thought getting my Broadcom wireless to work would be the hard part but I'm having real trouble with USB transfers for some reason. Tried to copy a 700MB .avi to a USB stick yesterday, I know it's good as I use it regularly. I get the KDE notification that it has copied the file (seemed far too quick but didn't think much of it) and then went to watch it.
Didn't show up on my telly and when I stuck it back in the computer to check it had only copied an arbitrary 39MB of the file. Tried again this morning, copying three albums to my phone - I get the notification that copying files has been completed almost instantly, I let it sit for five minutes and of the three albums one track has been transferred. It's an Android phone so I can use a file browser to confirm they are there, but they're all 0 bytes in size.
I'm running a system where we had a 62 TB XFS filesystem running on top of a LVM2 logical volumes (which in turn is comprised of 5 PVs, each of which is a external 16 bay RAID). Well, this weekend there were some I/O errors on the filesystem. I rebooted and then ran xfs_repair. The filesystem looked ok, but then I noticed using df, that it was only reporting 51 TB!
I looked at pvdisplay and also noticed the entry for one of the PVs is as follows:
Please note where it says that 12.00 TB is 'not usable'. I don't know what precisely is meant by 'not usable'. I looked back and it looks like it's been this way before the problems this weekend, but it is very suspicious.
I really have no idea as to how to proceed. I've never seen anything like this before. lvdisplay says the volume is 61.85 TB. parted says the filesystem on top of this volume is 68.0 TB. xfs_info says the volume is 51 TB, which is what df -h is also saying.
The system is Centos 5.x (not sure which version, but the kernel is 2.6.18-128.1.14.el5). Hardware is a Dell Poweredge 2950 with an LSI fusion SAS card, which is connected to a SecurStor ES RAID 16 bay unit w/ 4 additional JBODs.
I am running 10.04 Lucid on a Toshiba Satellite A105. The onboard video is an Intel Graphics Media Accelerator 950. The issue is that when I connect it to my Panasonic widescreen TV (laptop is widescreen as well) the display is shrunk and has a lot of unused space on the sides/top/bottom. So like, if I wanna watch something from Hulu, I plug in the S-Video, and I can watch on the TV, but it's not using all the screen available... I have not found a way to resize the output so it fills the screen.
