Networking :: SSH Between Two Linux Boxes / Newbie Having Troubles

Oct 27, 2010

I'm trying to set up a mini grid of linux boxes, but am quite new to setting linux up.I've installed fedora 13 on one and would like to be able to SSH in to it. All boxes are within a university network (under a proxy if that makes any difference?).I can mount a shared disc easily enough, and SSH out to other computers (that I didn't set up myself),I've tried following a few threads, temporarily taking down firewalls, disabling SELinux, messing around with iptables but can't seem to manage it.

Ubuntu Networking :: Newbie's WIFI Can't Find Home?

Jan 16, 2010

I'm new to Linux and Ubuntu 9.10. I have installed Ubuntu 9.10 on an older Compaq Presario 6100. Initially my built in wireless was not working. I searched the forum and was able to get my wireless working (I think) by installing the BCM43XX driver. I assume that works on my computer since I believe the BCM4306 driver is needed. Anyway, assuming my wireless is working, my home network does not show up in the pick list when I go to network<wireless.

I've spent a couple of hours already researching this and up someone can help me out. I would really like to give this new system a try.

Ubuntu :: Newbie Installing New Video Card?

May 13, 2010

I'm about to install a 'new' ATI Radeon video card into a Ubuntu 10.04 computer of mine (an ASUS A7VT) that has VIA onboard graphics. My question is, how will Ubuntu deal with this? Will it automatically download the required drivers or would I be better off with a fresh install after I've put the card in?

General :: Newbie Being Harassed By Password Prompts?

Jul 12, 2010

I just installed Ubuntu last night on a partition, and so far..There is one thing that may be a deal-breaker for me though: It seems that I am always prompted for a password!!!! When I first start my machine up...PASSWORD! O-K, once a day wouldn't be so bad...but if I let my display turn off while I'm away from the 'puter...I come back, and...PASSWORD?! Every time I try to do anything on the system....PASSWORD?!

I did a few things that I thought might solve the problem- I checked some boxes here and there, like "automatically log on" and made myself an administrator....but no matter what I do, I'm plagued by the password prompt 600 times a day and i can't take it!!!

Is there any way to stop this nonsense? This is WORSE than Windows UAC crapola!! (at least with that, you just have to click a button)- As much as I am loving Ubuntu....if there is no way to disable this password nonsense, I'm afraid I'll be heading back to Vista. I'm the only person who uses my computer (Although I think my dogs were playing on it while i was out fixing the tractor today...)- so I just need to know if there's a way to get rid of all this password-protected stuff?

Ubuntu :: Recommended Newbie Guide For Command Line?

Jul 20, 2010

I just installed Ubuntu 10.04 Server the other day, which gives me access to a command line only, to start out with. I'm hoping someone would be able to recommend a guide (online or a book, either way) for absolutely clueless beginners, so that I can learn to competently get around from the command line.

This would include information like:

Navigating the file system.
Editing text document.
Installing drivers.
Mounting data sources.
Installing and configuring packages.
and eventually installing a desktop environment.

Ubuntu :: Newbie Seeking Advice On Performance Improvement?

Aug 27, 2010

every now and then my company cleans its it trash by giving away computers to its employees. this i became the owner of a p4, 2ghz compaq evo with 512 mb ram and no hard drive. i bought a 500 gb hdd, dowloaded ubuntu, created a live disk and in a matter of minutes i had a new desktop! i love it! a new computer with a new operating system set by a non-techie in 15 minutes? not even microsoft can beat that. oh, and the total cost was zero!

then i started clearing issues (mysterious crash on p4 computers solved with a patch, screen resolution solved with a new mode, not recognized microsoft webcam to be solved, connection to stora nsa to be solved, etc.). this is nothing different from what you would go through installing windows on a new computer, in fact the process seemed easier for me as there's tons of documentation and people willing 1. overall system performance, mostly while browsing seems low. could it be the 512 mb of memory? would it improve its performance to jump to 1 or 2 gb? or it's just the processor that's too slow and not all the memory in the world would make it faster? while we're at it, is it reasonable to expect good performance on ubuntu 10.4 on a p4 2.0 ghz? (my notebook, a 2 ghz core duo runs faster on xp, but it has 3 gb memory, so i guess memory would help...).

2. choppy videos and other video, both in partial and full screen modes. again, would more ram help? updating drivers? updating flash? (i think it's all updated, but i'll retry...). or is my bottleneck in the processor? 3. my computer has an extra video card, but it's disconnected. i'm not sure about brand or model or even whether this would be an improvement on the on-board card. should i plug it and see what happens? would a better video card improve my performance?

simplifying, this is a computer for me to play and for my baby boy to pound at the keyboard. if i were to spend little money on it, what's the best investment, memory or a new video board? (i think i know the answer, memory). i don't want to extrapolate too much from my windows experience because this is a new os, but i think i would go for extra memory. if memory were the solution to all my problems... how much memory? should i go for an additional gb? full 2 gb? 3? what about buying a 1 gb card and plugging it side by side with the existing 512 mb? would 1.5 gb be enough?

I already figured out the basics of gtk2-perl, but i can't find a good tutorial for things like lists, scrolling viewports, drag n' drop, etc.

I guess any programming language is OK because it shouldn't be hard to translate it into Perl.

General :: Newbie Dual Boot Grub Menu Failure?

May 24, 2010

I'm running a dual-boot with linux mint and Windows. I have an E-machines desktop with : 760 GB Hard Drive 6GB RAM NVidia GeForce Graphics card 6150se Integrated AMD Athalon II X2 235e dual-core processor My problem is getting my grub to boot into Linux Mint, and the problem may lie with my graphics card. Whenever I install the linux mint for the first time, I am prompted to activate my proprietary NVidia graphics driver, which I do. Then I am asked to reboot.

Upon reboot, the system gets to the grub menu, accepts my selection to boot linux mint, then the "progress dots" appear on the screen. After about 8 seconds, the screen switches into command prompt mode. I never get to the graphical sign-on screen. All I get is the console sign-on prompts. From there my only option seems to be to reboot. (sudu reboot). After which, of course, I am forced to go into Windows vs. Linux to avoid the problem. Once Windows has loaded up, I do a restart and go back into Linux Mint . Finally, I get to the Linux sign-on graphical screen.

To summarize, i cannot restart linux mint without getting stuck staring at a console screen. I can get back into linux mint if i use the command 'sudo reboot', and, from the grub menu, choosing to go into Windows. From Windows, I then do a restart and end up back at the grub screen again, but this time when I select linux mint, things work and I am given the sign-on gui.

If I choose to not install the graphics driver (and put up with the annoying reminder to activate one), the system dual boots without a problem.

General :: Newbie Looking To Dual-boot Gloria X64 Into A Box Already Running Windows 7 X64

Dec 17, 2009

I recently installed Windows 7 64-bit on my Quad-Core 3GB RAM machine. I am now looking to dual-boot it with Linux Mint 7 64-bit. While I am an IT Service Management major, I really only know enough to be dangerous, and I don't want to ruin the first computer that I have ever bought outright. (Nor do I want to have to reload Windows 7 again.) I also want to be able to run Microsoft Office (I despise OpenOffice, so this is not an option), other programs native to Windows, and iTunes. Anyone know how to do this correctly?

Safe.txt contains:


And the error message generated is:

Try `iptables -h' or 'iptables --help' for more information.
