Problems and suggestions with hardware and Fedora Core 4

Problems and suggestions with hardware and Fedora Core 4

[Bargel Jazat]

Thanks for the suggestions about the problem on fc4.

- Guus: I ran a memtest and YES: I found some errors. So I guess I have to 
throw away
  my memory dimms (they are only 2 year old) and get new ones.
  *** So this might be the answer to this strange malfunctioning ! ***

- Axl: thanks, I will run the tests you suggested if the problem persists
  (bad blocks,  check your dmesg and /var/log/messages for errors.
   If there is a bad IDE CABLE then it would throw lots of errors in the 
dmesg.)

- Adam: I ran chkrootkit and found no problems. I have not run any virus 
check yet. Have
  viruses for Linux been reported?

  About the diff: the files normally had different content but same size. If 
I do further
  tests and the problem is still there I will post the diffs.

  I did the mirror with rsync -auv --delete <source> <target>

  About rsync: I think there is some problem with rsync or scp. I still have 
to find more information
  on the net. Anyway, I have a problem on another system when trying to copy 
a cd image from
  a Linux account to my local Windows machine (that has cygwin). The file 
transfer stalls at 99%
  and I have to restart it. So maybe this is another problem that affects 
scp and rsync and
  I have to sort this out separately. At the moment I always transfer md5 
sums of my files and
  check them after the transfer, but this check should be performed by scp, 
I guess.

  About fc4 being unstable: I installed it in June (or beginning of July, 
can't remember exactly).
  Then I did a very stupid move (I guess): did a blind upgrade with apt-get. 
The system became
  unstable and I had to reinstall fc4 on another partition. I am not yet 
finished getting all the previous
  configuration on the new partition.
  Anyway now I have fc4 with the packages that are distributed on the fc4 cd 
roms.

  Maybe fc4 is not stable enough (yet) for a production environment?
  I want to run a server for a web application I am writing. Would you 
suggest me to move
  back to fc3 or fc2?
  I have also considered moving to Debian (uses older versions of packages 
and kernel and
  should be more stable).

There are a few out there, they just don't propagate on *nix systems 
because of the pervasive security model.  I probably over reacted with 
that part of my advice, but whenever I hear a phrase like "a few binary 
files were different," I loose my head.

I would recommend against running any version of Fedora Core on a 
production system.  It is a bleeding edge distro used as "a proving 
ground for new technology."  If you like the redhat/fedora way of doing 
things, I can recommend CentOS:
