Fedora Core 6

Is Fedora's yum as good as Debian's and Ubuntu's apt-get?

[Eroberer]

apt-get is faster, I believe. I think it's generally considered a better program for that reason. Other than that, I don't know any differences. I just prefer yum, and I actually usually use the graphical interfaces for those things.

[aneeshm]

So do I. I use synaptic. A very good interface .

[Eroberer]

The few times that I used synaptic and apt-get, I couldn't find the programs that I wanted. This was with Ubuntu, and I didn't feel like learning how to add repositories to another Linux distro. It seemed like the repositories weren't as big. I just didn't appreciate it as much.

Hmmm. Now I have a problem. Not major, but annoying.

I can login to root from the login screen, but if I'm logged in as user then attempt to login to root from a terminal window it says "login incorrect".

?

[KrazyHorse]

Even more annoying: I want work to go on an external drive (FAT32)

I can compile **** there, but when I try to run, I get a "permission denied". However, my ls -l says that I have execute permission.

[mmcevoy@mattpc pythia]$ ls -l
total 8912
-rwxr-xr-x 1 mmcevoy root 2646783 Nov 25 15:21 pythia6409.f
-rwxr-xr-x 1 mmcevoy root 3496736 Nov 25 16:29 pythia6409.o
-rwxr-xr-x 1 mmcevoy root      25 Nov 25 15:49 test.f
-rw-r--r-- 1 mmcevoy root      19 Nov 25 15:46 test.f~
-rwxr-xr-x 1 mmcevoy root 2920791 Nov 25 16:30 test.out
[mmcevoy@mattpc pythia]$ ./test.out
bash: ./test.out: Permission denied

Did you do 'su' to get root while you were logged in with someone else? 'su' = superuser?

FWIW, the command 'll' is already shortcutted to ls -l in FC. So just type ll to do ls -l.

My only guess about the permissions is that your external drive is mounted in a way that doesn't allow you to execute anything. Can you put some other executables on there and try to do run them? I have no idea how to change this, if it is in fact the problem you are having. linuxquestions.org and linuxforums.org are the two best Linux boards that I know about for questions.

Errr..no. Thanks

My only excuse there is that I've never been allowed to login as root in any other *nix system (I've only had user accounts on other people's systems)

[KrazyHorse]

Okay. Even root doesn't let me execute on the external drive.

That's understandable. How did you used to work on these Linux/Unix boxes? Did you SSH into them with a terminal? The reason I'm asking is because that's what I used to do for one of my comp sci classes (till I setup my own Linux box). I think most FC installations start running OpenSSH by default, and you can SSH into your own Linux box from remote locations if you really wanted to. This was something that I initially found very useful with my setup, so I thought I'd share.

I'm booting up one of my systems to test my earlier theory. I don't know if I'll be able to help, though. Can you copy the file to a different mounted drive (like to the desktop) and execute it? ...just testing.

[KrazyHorse]

No, I have my own box, but it's on a network with a bunch of other machines. Each user has a different login to 2 or 3 of the machines (same password, but like username@machine1, username@machine2 etc). These different logins share the /home/username folder. All different users (username1@machine1, username2@machine2) share common admin stuff, utils etc. When I wanted to install stuff I had to install it to /home/username, which was a ***** when Adobe stopped working and nobody could be bothered to fix it.

I usually write and test run programs on my own box, then run them for real on one of the shared machines (so that I'm not stuck working on a slow-ass computer while waiting for a 15 hour run to go through)

In other words, I write example.f on my computer, save, test on a short run, debug etc until it was ready for primetime. Then I compile example.f, ssh into remotemachine, and run
example.out > example.dat &

The problem is that when I'm at home I don't have editting and compiling stuff in Windows, so if I wanted to work from home I had to either try to edit in terminal emacs (blech) or copy to home, edit, copy back, compile, run, copy to home, debug etc.

Now even if I want to run a big job I can do all my testing and debugging at home and then only copy stuff once when it's ready to go. Plus I can make plots easier (gnuplot) etc.

Yeah. Did it earlier. It works fine. There's something with the drive. I know that VFAT messes with permissions(?) but I was under the impression that if it shows you having x access it should let let you x....

[KrazyHorse]

I guess I could boot to Windows, shrink my partitions and create an ext2 partition in the free space, then move the stuff to there and test if that has anything to do with it.

By the way, the drive automounted. I didn't mount it manually.

BTW KH,
why are you doing all this if I may ask?
Out of interest or because you're doing something that requires Linux?
If the later, what?
