unzipping: file size limit exceeded

peeples · 10-13-2002, 08:50 AM

I'm doing LFS this weekend. /dev/hda2 was about 30 Gb, so I used parted to shrink it for some extended partitions (/dev/hda5 @ 5Gb and /dev/hda6 @ 5Gb). When I am using bunzip2 to unzip some large .bz2 files (like linux kernel or gcc) I get an error "File size limit exceeded". I have figured out that if I ctrl-alt-F2 and log in as root, that I am able to unzip the file. So root does not have these restrictions.

I'll bet this is the reason I couldn't download some iso's the other day. I was trying to put them on one of these extended partitions. Everytime the download got to 102.4 Mb, gFTP would quit downloading and the program would close itself.

Where do I go to change this limit? Searches on Google brought up a lot of people having this problem using mk2fs, but their cures were patches to files (I don't really understand how to use those).

TIA

Do you have quota installed?

peeples · 10-13-2002, 11:37 AM

I went into root account and typed "quota" and got the response that root had no limits (or something to that effect). If this is the problem, how do I turn quota's off? I am the only user on this PC, and I don't need it.

Log as your normal user and type
quota -v
If you get something (not error message) please post it here.

If not quota's, it could be a Bash imposed limit. Run this command: ulimit -a

Look if you have a limit for the "File size" - this is the maximum size of files you are allowed to create.

See the bash man page how you can change this.

peeples @ /home/peeples >> What do YOU want ?!?
quota -v
Disk quotas for user peeples (uid 506): none

ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
file size (blocks, -f) 100000
max locked memory (kbytes, -l) unlimited
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 1024
virtual memory (kbytes, -v) unlimited

SO, I guess it's a limit imposed by bash. Going to do some research on Google right now...

I've never seen this problem... kindof interesting though.

I looked through "man bash" and found this:

ulimit [-SHacdflmnpstuv [limit]]
Provides control over the resources available to
the shell and to processes started by it, on sys-
tems that allow such control.
(later)

If limit is given, it is the new value of the spec-
ified resource (the -a option is display only). If
no option is given, then -f is assumed.

-f The maximum size of files created by the
shell

so it looks like maybe you should get rid of "ulimit -<whatever>" from your $HOME/.bash_profile or $HOME/.bashrc

I think that may do the job....

good luck

I went into $HOME/.bash_profile and added a line:
ulimit -f unlimited

Next login, I got a "You don't have permission to do that" kinda answer. SO, I put :
sudo ulimit -f unlimited

(I'm already set up in sudoers). Then I got a "sudo: ulimit: File or directory not found".

Then, I decided to put it in /etc/profile instead of my .bash_profile (that way ALL logins would have the new limit), but I got the same results. I must be doing something wrong. BTW, I did a "locate ulimit", and only found 2 header files(*.h) and 2 man pages, so I did updatedb, tried again, same result. So, I can't even find the offending program...

I REALLY love my new LFS. It is way faster than RH7.3 to get to the CLI login. Plus I learned so much, I think I might have to be inducted into the "guru" clan soon... (I think the more I learn, the more I realize that I have even more to learn...)

adam_boz · 10-14-2002, 02:39 PM

I don't know what you should do... the only thing I can say is that when I did "man ulimit" it gave me info on the header file, but it said it was outdated. If you do "man bash" way down there you'll find it.

I was wondering where it would be set... it seems to me that if you put it in ~/.bash_profile or something, that the user would be able to change it.... kindof goes against what it's used for?

I figured it out!!! I had installed a program that "helps" with security called Bastille. It asks a whole bunch of questions and then changes your system to make it more secure. One of the questions had to do with limiting user abilities. I turned off Bastille and everything is fixed now. SO, users beware. I'll rerun the setup program later, and answer the question differently...

Thanks everybody for the help.
