I just used dd to clone a linux partition to a new hard drive, it had 800mb left on the old hard drive, after dd, new hard drive lists 1.29/1.3 terabytes full. Is this what happens by default in dd? How can I fix this?
I'm trying to figure out how to access the local part and the domain part of an email address in postfix's main.cf. For example, email@example.com has myname as the local part and mydomain.net as the domain part.I get the whole email address with %s. I want to speed up the lookups by writing better database queries.I've had no luck finding this in the otherwise well documented postfix.
we have access to one domain name , 1 internet ip address and may servers hosting different part of site. I want them all to be accessed via same web site . some of the server in our network are embedded devices.they have their specific utility being hosted on that machine. So the severs are bound to be distributed . I just wanted to know how can I access them via single ip, domain name.
I have RHEL3 installed on my machine, It is having lot of data and 2 databases oracle and mysql are running on it. Now my cpu is having problem and it is going to be replaced by the new one. Hard disk is fine.
Whether the new CPU will be able to boot with the old hard disk. If not is there any way so that i can recover everything with the old hard disk. SO that i need not have to install any packages and configuration seetings after the replacement.
I run an ISP with various servers such as mail servers.Once something works I let it run forever. Thus I have a mail server running FC5 on a Mach Speed pm400 via chip set motherboard.Recently the motherboard died, and I had to use a back up board to get it going again.I am now out of back up boards and need to purchase a new set for the future.However the mail server software will not activate the IDE DMA on these newer boards because the chip set drivers are not in the last kernel package that yum would download for FC5.
1.) Is there an easy fix to this problem to get the DMA working?
2.) Do I have to download and compile a latest kernel (2.6.x) to get the right drivers?
3.) Since FC5 is fully modularized, is there an easy way to create a similar kernel from a download without having to manually turn all the modules on?
4.) CAn I simply use the original .config from my existing kernel in the new one?
I have installed Fedora 14 on Intel's DH67BL mother board, which has a on board LAN port, Fedora 14 does not detect on-board LAN. Unfortunately, intel does not provide any driver support for linux OS :-(. However, if I install an additional LAN card, Fedora 14 detects it and everything works fine.
I am trying to switch from the video device built into the mother board, to a card i just put into my machine. I'm using gnome and don't know where to start. I shouldn't need new drivers (based on a possible misunderstanding) because I am going from a nvidia 6100 to a 8600. I have looked in various places like the control center but haven't had any luck. I just started using linux and have very little experience in the terminal. Issues with the current card are stopping me in my learning process.
I have installed Ubuntu 9.04 uname -r 2.6.28-11-generic
Checked cable/network with 386Box running Ubuntu 8.04 all OK. Could not get Realtek 8168 on mother board to work on Gigabyte H55M-S2H motherboard. I tried to install r8168 driver but no luck ... so I bought another Linux compatible card which turned out to be a RTL8139c (eth1) and the driver I am using on this is card is 8139too.
My preference would be to get the motherboard ethernet working but perhaps the card may be easier to get working. Anyway after searching the net for ideas and trying different things I've just about given up. I have reinstalled Ubuntu today so eth0 is back to using the r8169 driver. I'm no expert so my attempts at following other recipies have so far failed. From what I have read the 8139too driver should have worked with the RTL8139C chip so I have run out of ideas. I must be doing something wrong.
my laptop is kinda broken and the right part of my 1440x900 display doesn't work anymore (all black). I think i have around 1200x900 left on the left side. Is there a way to tell X to only use those for displaying the desktop?Does this work with other application using "fullscreen" ?
Is there a way I can use my Flash Drive as part of my Hard Drive? Can I merge them together or something? To make my hard drive go from 20GB to 22GB? I know it is a petty 2GB but it would mean the world to my PC... I would like to increase my partition to include the Flash Drive to... can I do that?
would the following command wipe an entire drive clean (partition table included)? Code: dd if=/dev/urandom of=/dev/sda bs=512.I was wondering what the 'bs' part means? Would it be better to omit that?
I was trying to delete a printer software package and some how managed to do away with part of my system.Guess I clicked on something I shouldn't have.Before I realized what was going on about a page of deleting this and that zipped by before I aborted.Is there a way of finding out what was deleted so I can put it back together?The stuff in my home folder is still intact, so if I have to do a new install it's no biggy.Just hoping I wouldn't have to.Had to reinstall dolphin just to see that the home folder was still there and intact.
I have Evolution contact manager, works well but I cant seem to see the bottom of the screen, its cut off. Is there a way to change the screen size (particularly the Contact/Editor/Personal Information as I want to access the "notes" part of the application" Opensuse Gnome 11.1 on Lenovo S10e Netbook!
i have 4 different harddriveparts (i hope that is the correct translation), on my PC, one for the OS (ubuntu) and 3 others for programms and documents for example. But now i need to go in a folder on another part in the console.
The other part has the id E61441A014417519, so i would guess that the order you have to enter would be: "cd mediaE61441A014417519folder" and then i would be "in" the folder, but the console said that there is not even a folder named "E61441A014417519".
I know that the question could sound weird but...I was wondering if is possible to download one or more parts of a file.
For example, the first 10 mb, or the latter ones.
I know that there are some apps that let you do segmented downloads, but, is there anyone that let you choose the segment to be downloaded? If not, can this be accomplished with any linux command-line application?
I have blocked all connection with iptables and allowed only the loopback: iptables -A INPUT -i lo -j ACCEPT iptables -A OUTPUT -o lo -j ACCEPT iptables -P INPUT DROP iptables -P OUTPUT DROP iptables -P FORWARD DROP
Next I want to allow only ssh connections, and also I want to record the IP address of each attempt to access port 22 using the recent module. Then I want to to see if that IP address has attempted to connect 2 or more times within the last 60 seconds, and if not then the packet is accepted: iptables -A INPUT -p tcp --dport 22 -m recent --set --name ssh --rsource iptables -A INPUT -p tcp --dport 22 -m recent ! --rcheck --seconds 60 --hitcount 2 --name ssh --rsource -j ACCEPT iptables -A OUTPUT -p tcp --sport 22 -j ACCEPT iptables -A OUTPUT -p tcp --dport 22 -j ACCEPT iptables -A INPUT -p tcp --sport 22 -j ACCEPT iptables -A INPUT -j DROP iptables -A OUTPUT -j DROP
I'm trying to extract .part files. These are mac extensions similar to .rar or .zip. I need to extract a whole bunch of them simultaneously. Theyre probably registered in sequence just like .rar files. What program can I yum install or where should I look to extract these to what will probably be an ISO.
I am trying to set up a free wireless network for clients for a small business. I have a wireless router that I plan on hooking up to our main router. I want to keep all the computers that are associated with the wireless router from being able to access the rest of the network hooked up to our main router. I think one solution might be to put the wireless router in a DMZ. I think this should isolate it from the rest of the network (and have a side-effect of sending outside traffic to the wireless router, which shouldn't matter). Will this work? Also, if I just make both routers have the same subnet (e.g. 192.168.1.x), will my wireless router just filter out requests for computers on our main network as requests for (non-existent) computers on its local network? Any other ideas are welcome.
I have just re transcoded a bunch of avi's. to tell the new ones from the old ones I put '[xvid]' at the end of all the new avi's. but now I have deleated the old avi's I want to remove the [xvid] part of the file name. This is what I have so far
Code: #!/bin/bash for name in *.avi do newname=`echo "$name" | tr -d [xvid]`
