Jan 23, 2010My son's desktop has Fedora 12 and a wireless card. Everything worked for a long time until one fine day the network management just disappeared from both System/Preferences menu and the panel on top.I can run a Live CD with Fedora 12 on that machine and it immediately connects to our home wireless network. Booting from hard drive has no sign of NM. Trying to run 'yum install NetworkManager-gnome' does nothing because there is no connection. Running the same command as a LiveUser from CD does seem to install everything (but where to???), no errors reported, and still the is no network functionality upon reboot from the hard drive, even when plugging to LAN with a cable.It seems that I need NetworkManager in order to go online in order to install NetworkManager.I have other computers at home that work fine, I was able to download a couple of archives with NM, but I am new to Linux and have no idea what to do with those files.I could not find any step-by-step installation guides for NM, especially when the computer has no connection at all.

Jun 26, 2011Recent refugee from Ubuntu here. Fedora fan for one month.I have two computers that access the Internet through a router. They are assigned IPs dynamically by the router's DHCP. I need each computer to be able to "see" some shared folder on the other one, with RW permissions to that folder and its content.I want to use Nautilus to access those folders from each computer.
Tried NFS, Samba, gnome-user-share to no avail.
Willing to kill Fedora's firewall forever in order to ease folder sharing.Can some kind and knowledgeable person try a step by step setup guide for this? As an 8-year Linux user I am not afraid of command line interfaces.

Sep 4, 2010I have read a bajillion tutorials and have gotten nowhere. This is my first Linux box, and it has been nothing but headaches. i'm pretty handy around computers, I took a Unix class, and I used Dos as a kid, but i'm just having so much trouble with this.I just want to remotely control my Ubuntu box from my windows laptop over my home network. That's it. I cannot find one comprehensive step-by-step tutorial that will show me how to do this. Everything I find assumes I know at least something about linux, and I don't.
I have Putty, realvnc and tightvnc viewer installed on my laptop.I have open-ssh and vx11 somethingorotherinstalled on the Ubuntu box. I have also allowed remote connections on Ubuntu from system>preferences. I am getting very frustrated and would really appreciate someone giving me some help. So far I HAVE been able to remotely control the box through one method. Through the GUI on ubuntu I went to: System>Preferences>network connections
and set the server to static IP, then I was able to use real VNC viewer from my windows machine to connect to the IP I set (192.168.0.11) but I couldn't get there through servername.local or whatever it said. The problem witht his solution is that the Ubuntu box then couldn't connect to the internet (which I need it to do.) someone please please please direct me to the information I need for this simple task. I just need to remotely control the desktop, the reason I wanted to use vnc through ssh so that I can leave the ubuntu box headless. Using just VNC I was having problems when the box was rebooted (had to log in before I could remotely control it... something about a security key ring?)

Networking :: Up-/download Rate For A Single Host (from Shell)?
Jan 25, 2011I have a slave node uploading all kinds of backups to my server in the internet. Now I would like to display the actual upload and download rate to this server (not the entire nic-traffic, any protocol) in a small php-page for easy monitoring.I had a look at quite some monitoring tools and the one which kind of offers what I am looking for is iftop with a filter on the IP of my server. As I would like to periodically update a file with the actual rates, an interactive program won't do. A possibility would be to filter the packages myself using but this seems to be quite a long shot.The optimal solution would be a program or script printing out the actual upload to a host specified in the options to STDOUT

View 3 Replies View RelatedGeneral :: Shell Script To Extract Single Report By Pattern Then Both Backward And Forward
Feb 18, 2010I have to admit that I register to LQ after I failed to search for similar solutions.let me see whether I can explain my problem clearly. I need to extract a single report from a big file. The big file looks something like this:
Report for yyyyyy
Your info 999-9999999
End of Report
[code]....
I need to search for a user provided string, say 999-9999999, in the big file. Then I have to extract the single report. My logic is simple,
1) find 999-9999999
2) backward search for "Report for", note down the line number
3) forward search for "End of Report", note down the line number
4) extract the record by using info found from step 2) and 3).
I am trying to do this in bash, with awk and sed (I am new to both).
Ubuntu :: Writing A Single Shell Script To Change Preview Settings And A Launcher's Icon
Mar 22, 2010I want to write a single shell script that allows me to, once executed from a panel launcher, change the image preview setting between "local files only" and never. Right now i have two tiny scripts, one for local files only and another one for never, that is:
[Code]...
and the other says string "local_only". But that means i need to have two launchers, because i don't know how to write the condition <<when set to never, change it to local only. And is it possible to make a script that also changes the launcher's icon when the preview config is set to one or the other value? That way i'd know what it is set to just by looking at it. It would act as a diagnostic and therapeutic tool XD
