Hi,
If I have a data center hosting email, which I want to give people POP3 access to, and the hard drive runs out of capacity, how do I add a server into the mix? ie. so that when a user checks their mail, there'll be a POP3 server on ONE server answering, but their mail will be downloaded from the server that has it? (ie. the system has to keep track WHICH server their mail is on)

Thanks.

Try this:

a=-m
echo $a

a=-n
echo $a

You would find the 2nd set commands would not set a to -n but empty value.

And also try the pattern match with extglob:

shopt -s extglob

a="-w 123 -m 456"
echo $a
echo ${a/-w +([0-9])/}

a="-w 123 -n 456"
echo $a
echo ${a/-w +([0-9])/}

The 1st set commands would remove `-w 123' as expected, but the 2nd set commands would also remove -n as well.

Is this a bug or something special for bash?

First off here is the hardware specs of my machine:

CPU: AMD Phenom II X6 1035T
MOBO: GA-880GM-USB3 (Socket M2)
GPU: 1024MB GeForce GTS 450 (MSI)
DVD: Optiarc DVD RW AD-7280S SATA
HDD: 932GB Seagate ST1000DM 003-1CH162 SATA
RAM: 16.0 GB Dual-Channel DDR3 686MHz
MOUSE: Rat7

This problem I am about to describe has occurred consistently on the following distros:

Ubuntu 12 - tried GNOME
Fedora 17&18 - tried GNOME & Cinnamon
Linux Mint 15 - tried Cinnamon

Also occurs on the live cd's of all of the above Distros


Problem:
Generally after logging in, my desktop will be usable for a few minutes with no problems, providing I don't open Firefox. After I open firefox or at some other random point (at this point firefox is the only thing that consistently causes this problem)things start going funky. Please note that these problems also occur on a Live CD. Here is a list of the symptoms:

- Mouse only works in the active window.
- Can not switch active window using the mouse, only keyboard (Alt + Tab or have 1 window per workspace and switch workspaces with Ctl + Alt + arrow)
- can not re-size active window
- can not get a right click menu on the desktop
- can not use any GNOME/Cinnamon desktop menus
- must restart the computer to get this problem to resolve

I would assume there is an issue with either X or GNOME because this has happened on multiple distros. I have not tried KDE and thought that maybe there might be a change if I got away from GNOME entirely.

This problem makes the desktop entirely unusable unless you quickly open a terminal window in another workspace and then use it once the desktop goes haywire.

I need a write a script that searches all specific types of files (.php/.html/.js.. etc) for a list of regular expressions. The actual purpose of the script is to detect files containing known malware.


Here is the catch, I will be adding regular expressions to this script very often so I need to create something that gets these regular expressions from another file that I can easily add to.

I am very, very, proficient in bash scripting, thus created the script using bash. The current script finds a list of the files using find, then loops though all of them using grep to search the files for the expression. It greps each file multiple times (once for each regular expression.) This method obviously takes a very long time and on a less important note, is quite resource intensive.

Is there any other easier way anybody knows how to do this? I would prefer bash, since I already know that, but I would be willing to learn and recreate it in another language if it would be more efficient.

Pretty much looking for idea, links or specific functions that may help me achieve my goal. Anyone have any ideas about this?

Thanks in advance.

Any ideas ?

I have two machines with Centos 6.4, I used ndiswrapper to install D-Link DWA-130 onto the machines, but whenever WiFi pops up, the machine just hangs up, I was totally frustrated!!!!


Is this a bug with Centos 6.4?

My server gets internet. My client sees the network and gets a dhcp IP lease i see it in ipconfig. However it gets an error dns detected but not repsonding.

I have found many different tutorials and am very lost.

I have ubuntu 12.04 server, bind9, dhcp, have gui and Webmin and 2 ethernet cards eth0 and eth1. This will be a squid proxy servver which it is loaded. i tried to work with dnsmasq but would come up - one place said conflict with NM in 12.04. I don't know if my zones are wrong if i have the wrong nameserver.

I am really (somewhat) confused but I think it is a simple fix. I need this done soon..been looking online for 1.5 weeks. I need someone to may be review my work.

I can't seem to perform any actions through aptitude. I am using Debian 6.0.5 on virtual box 4.1.16.

I have 3 machines on my virtual network, the first machine routera can perform apt-get update, install etc. However the other 2 machines can't. To make sure it wasn't a problem with the network settings I changed the network adapter of routerb, from intnet to NAT. This hasn't helped the issue.

I can successfully ping "aptitude", "Google" and can even ping the IP address of the FTP server that is given when I perform apt-get update.

Through examining the /etc/apt/sources.list file I am no further forward. I compared routerb's sources.list file with that of the functioning routera's, both are the same.

I have provided a screenshot of both these .list files of both machines. Help would be greatly appreciated.

Hello.

Im new here, but this forum already helped me a lot of times by googling.

I need a help with my new debian wheezy server. I'm a linux user for +8years and already spend hours trying to solve this and couldn't :( so if anyone has a clue.. please help?



The problem:
I replaced my old server running debian-6.0 with a new one running debian-7.0. I have a DYMO LabelWriter 450 USB Printer on it to print labels.

The labels are printed by a postscript using the lpr command:
lpr -#$qtd -r -P DYMO_LabelWriter_450 /path/to/my/postscript.ps

If i send more than one label to the printer, this command will run multiple times changing only the postscript file path (different label, different ps).

The problem is: the printer pauses seconds between each job/label... and this behavior wasn't like that before - before the printer prints one after another without pauses.



I already tried a lot of things and nothing worked.

One thing i noticed is i got this message for each job i send:
Jun 18 11:26:55 kernel: [ 723.602744] usblp0: USB Bidirectional printer dev 2 if 1 alt 0 proto 2 vid 0x04E8 pid 0x3433
Jun 18 11:27:08 kernel: [ 735.820344] usblp0: removed
Jun 18 11:27:08 kernel: [ 735.821795] usblp0: USB Bidirectional printer dev 2 if 1 alt 0 proto 2 vid 0x04E8 pid 0x3433
Jun 18 11:27:18 kernel: [ 746.219856] usblp0: removed
Jun 18 11:27:18 kernel: [ 746.221544] usblp0: USB Bidirectional printer dev 2 if 1 alt 0 proto 2 vid 0x04E8 pid 0x3433


i already tried to copy my old /etc/cups folder into my new server.
i tried to remove usblp module and blacklist it..
i tried to reinstall the printer in cups..
i tried cups 1.6.2 insted of 1.5 too
and tried more things.. without sucess :(



The problem is.. the printer is pausing between jobs.. how do i remove that? any ideas!?


I'm getting crazy about this !

I was wondering if any one has succeeded running Generals by Command and Conquer on any flavor of Linux with any type of emulation. I have tried with Wine to no success! Please don;t suggest to run it on a virtual machine as its too slow in there

hi,

i am almost fresh in embedded Linux, i want to test LDD3 examples, for that i install fedora 4 in my VM, i am unable to compile the kernel, i have set configs using make menuconfig, and then try to make compile but it gives me errors like


could somebody inform me i could be missing, or where i can test LDD3 examples with zero defects

Thanks

How do I enable hibernate on lid close, and on low battery power, as well as enable the hibernate button to appear alongside shutdown, suspend and restart? pm-hibernate works(most of the time!) fine, but I really want lid close to trigger hibernate!

Thanks!

Hello All
Hope this is the forum to post this.
I'm using Ubuntu 12.04.
I would like to know how do I check for malware? How do I remove it if my system has it?
Thank you for your help.
