General :: Ubuntu - Cheatsheet For Commands To Save System?

May 20, 2010

I've recently lost my window options, had to somehow manipulate my way to Xchat and ask some people how do I get it back (it was metacity --replace, and after I decided to stop the command and run it in background the X was completely useless so I had to do killall -u user). And that was after the internet connection stopped working for some reason (might've been the ISP).

The thing is, after using linux a long time, I still get the feeling that on dire situations, I don't know the good tricks (stuff like metacity --replace). I feel like a really need like a "rescue" cheatsheet for things like: how to save the X no matter what without pressing reset how to reset the system to "normal state" how to connect to the internet through the command line how to monitor what the X is doing (using ubuntu linux 10.04 btw)

General :: Copy From 1 Computer To Another With System Shell Commands?

Jun 23, 2011

I want to copy a file (home/remote_computer_user/Desktop/test1.txt) from my remote office computer (a permanent URL + open port) to my home computer (home/home_computer_user/Downloads/).

How can I do this with shell commands in Linux?

My current thoughts:

ssh <user>@<computer1address> -p <port> - gives me a shell on the remote computer
(I think I should use scp, but I dont how exactly how in my case)

What are the exact commands I should use?

General :: System Crash Doesn't Save Info To Kern.log

Jul 23, 2010

I am currently creating a usb device driver consisting of mostly read and write commands. It can successfully read/write using the bulk endpoints, however reading from the interrupt endpoint causes a system crash.As the crash happens whilst writing to kern.log, the file doesn't get a chance to close, therefore done of my debug printk calls are saved. Also, I get know response from using the magic sysrq key.

Does anyone have an ideas on how I can get any system information about what's causing the crash, or possible causes of the crash. (Using a usb sniffer running on another pc, I can see that the packet is coming in from the interrupt endpoint).

Ubuntu Multimedia :: Can't Get The System To Save Resolution - Nvidia Card

Jan 30, 2011

Running Ubuntu 10.04 with an Acer wide monitor, 1600x900. The graphics card is a Gefoce 6200. When I run nvidia-settings I can select 1600-900 and it looks fine. I can "Save to X configuration file" and get no errors. However if I log out and back in, the resolution changes to 1360x768 which causes the tool bar at the top to be mostly somewhere to the left of and above the monitor. It makes life rather difficult when you can't get to the Applications and Places menus. I also tried nvidia-configure but it created essentially the same xorg.conf file.

This is the xorg.conf file generated:


# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 1.0 (buildmeister@builder75) Sun Nov 8 21:50:38 PST 2009
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildd@palmer) Fri Apr 9 10:35:18 UTC 2010


1600x900 is the native mode of this monitor so the driver shouldn't be getting any errors if it trys to set that resolution.

Server :: System-config-bind Unable To Save ?

Aug 16, 2010

Not sure why but I keep on getting the ERROR: Path is not writable when I'm trying to add a Slave Zone.

The server was commissioned by someone else and I remotely installed GNOME group, and vncserver as per the official CentOS instructions here.

Initially I tried using a normal (ie non root) user's credential for my VNC session. However, instead of asking me for my root password when I tried to open system-config-bind, it just doesn't load up. I ended up allowing the user "root" to connect to the server remotely via VNC, and was able to get system-config-bind to start.

However, I am now unable to save the settings, despite having done:

General :: Save Iptables When Iptables-save Doesn't Exist?

Apr 14, 2011

I'm working on a Soekris net4801 that is running an unknown distro of Linux. The kernel is 2.4.29, and iptables is v1.3.4.

I can't work out how to save the iptables. I searched the whole system for files/folders containing the name "iptables" and got 3 results:


I've tried iptables save, iptables-save and iptables save active.

"iptables save" and "iptables save active" give me an invalid argument error. "iptables-save" isn't a valid command. "iptables --help" gives me a list of valid switches, none of which have to do with saving.

how I can save the iptables?
