Well, as many proxy applications, GNOME Network Proxy Preferences only allow to ignore hosts. What I want to do is exactly the opposite. I only want to use the proxy for few sites. Is it possible to define only the allowed hosts in any way?
PS: I know FoxyProxy add-on for Firefox does this, but 1)I don't use Firefox and 2)I want the proxy settings system wide not only for browser.
I'm trying to use ssh-keyscan to get some known_host file population going on, but I have a ton of hosts I want to scan, all with multiple aliases in /etc/hosts. Is there a way to use my current /etc/hosts file to do an ssh-keyscan instead of making a special list of hosts that (from what I've read) ssh-keyscan needs?
I've modified the Radiance theme and installed it, and everything looks wonderful except for one thing. Certain programs have ugly windows and progress bars, as if all window effects were disabled for those windows. The progress bar in GIMP is not affected.
I have Ubuntu 10.04 but I installed KDE for a try(which I'm not liking by the way >_>)I can use the volume control in GNOME still and I can control it with PusleAudio but I can't use my keyboard buttons for Pulse, only KMix. In Kmix though I can't find a master channel for HDMI.
I sometimes experience rather significant visual artifacts in Maverick. Some programs are more affected than others, but the problem is systemwide. It's most obvious when trying to read a pdf-file, as you can see in the attachments.
Interestingly, video never seems to be affected; even when the artifacts are so bad I can barely see what I'm doing, watching a movie in VLC works without problem (although the VLC GUI itself is affected).
The problem doesn't appear every session, but it is common. Approximately every third session is affected, and once the artifacts appear they remain until I restart the computer.
Probably an easy (which means stoopid) question...I am trying to reroute a website using my hosts file so that it matches my servers certificate file for testing without effect dns and the live site.When I went to edit my /etc/hosts file it is non-existent. I have, I am assuming in it's place, hosts.allow and hosts.deny. Can anyone explain why I do not have a hosts file?
I started to have a particular problem with my hard drivers, I can hear how they do a weird noise, like the one that a hard disk does when you start your PC, but it's very often once per second while I use my computer, if the computer is idle nothing happens. Sometimes it says that the error it is on ata3, sometimes it is on ata5
[code]...
What could be the problem? I have 4 SATA disks, in 2 of these disks I have in each one a partition of 250 GB and are mirror under mdadm as raid1. What about the names ata3 ata5 which are the real disks affected?
Just switched my laptop from that other operating system to openSUSE11.2. Everything works great except for one odd little bug. Both my speakers and headphones have output, are affected by the volume control and it even detects when I plug in headphones and stops output to the speakers. However the moment I adjust the volume, output to my headphones stops, and my speakers start.

Not sure what iis going on, I can ping some hosts on the internet but not others see below (adobe is not the only example) Works OK from another host on the same network with same GW and DNS iptables is turned off

I have a problem reaching some hosts on the Internet, namely newegg.com and djangoproject.com. On the same machine and network connection using Windows 7 the host names resolve properly and I can connect to them. The host names are resolving in Ubuntu, but I cannot connect to them.
I'm using NAT on an AP with linux. Is it possible to route an OUTGOING host not over NAT?
I'm using SNAT but could also use MAQUERADING I think. Because both are in POSTROUTING table and this table is the last one I don't think there is a solution or is there any solution?
Background: I'm using a local VoIp client which I want to have an own ip for routing question in my network but don't want all other local machines as seperate ip's because if done so i.e. without NAT the routing table is very complicated ...
How can I find all the devices(printers,etc...) and computers along with their OS if any installed that are connected in my intranet (devices/computers may be down here)?
I did this earlier using netstat or nmap not sure what I used and how I did.
I have to build a netwrok for small lab and office setup.Setup as belowI have a PC running with Centos 5.4 and has 4 NIC cards. eth0, eth1, eth2 and eth3
I have a small office network with windows machines and a Linux Internet access server (CentOS 5.4). For Internet access I use masquerade, so everione can access every Internet service. I periodicali have quite big traffic from one of the hosts, but I can't figure out which one is that?
Is there any linux command which will show me the bytes/packets (or any useful infos) going to specific hosts?
I bought a network printer, gave it a host name, address should be assigned by my cable or DSL router. Thats what DHCP and DNS is made for right?Now I will print to that printer from my (Lucid) Kubuntu box and resolve it by it's hostname.I can't ping it by printername, I can't ping it by printername.local.It works when I login my router, read out the IP address and hostname the printer registered at the routers DHCP-table and use that address.What can be done that a router transfers the hostnames it has in it's IP-table to clients upon DHCP resolve AND whenever a client get's a new IP-Address?
What happen if we assign a static IP address to both linux and windows host?Consider host A is a ubuntu machine and host B is a windows machine. I first set a static IP for host A (W.X.Y.Z) and connect to it through ssh. Then I duplicate that IP for host B (W.X.Y.Z).The result was that I could no longer connect to the ubuntu machine!
I have read the man files on hosts (deny/allow) and think I understand how they are supposed to work but reality has proven me wrong.
My simple test case was to add "ALL: ALL " to the end of hosts.deny which I though should make the Internet not work. I can still look up hosts fine so apparently I don't understand these files or Ubuntu is ignoring them.
This is my hosts.deny file

and hosts

hosts.deny is the only file I have edited (so far)
The wireless connected hosts do not respond to pings from wired ones or other wireless ones. And all the wired connected hosts respond to pings from any wireless one. The same problem applies also to ssh connections exactly as in the ping issue.
The switch the ADSL modem/router and the Access point are all 3 different machines correctly connected to each other. I do not have a firewall in any of my hosts, all run Slackware 13.1, the wireless ones use "wext" driver and not "ndiswrapper". All wireless hosts login successfully, WPA & DHCP works fine and internet connection goes without a problem. But the fact I can only connect from a wireless host to a wired one is puzzling.
I just changed my CentOS server from DHCP to static IP address. After the change, I cannot ping other hosts on the same subnet. (I can ping the CentOS itself).The IP address of CentOS is 192.168.0.202.After pinging 192.168.0.106 (106 is on and other host can ping it), arp -a shows? (192.168.0.106) at <incomplete> on eth0 It looks ARP cannot resolve MAC address of hosts 192.168.0.106.
I Own a netcafe and I want to limit the netspeed for some of the users on the network because some of them maybe use torrent or other ways to eat the bandwidth and the net became so slow for other users.
My task is a way to limit the net speed for some users on the network, I tried a mikrotik RouterOS but it look like a miss to install I wanted an easier way than this, I use linux or windows or any OS to make this task done please help me to do it !!
I have set up a home network using a modem/router, which my devices connect to via ethernet and wireless. I have got it working but i'm still not happy (stick with me...)!
I have settings configured so as to utilise DHCP, so IP addresses for the different machines are automatically assigned by the modem/router (as i understand it). I then obtained these auto-assigned IPs by running ifconfig on each device. I tested connections between the devices by pinging each other using these IPs (ie ping 192.168.2.2).
BUT I want to be able to use hostnames (ie ping dandelion) instead, and the only way I can make this work is to add hosts and corresponding IPs into the /etc/hosts file.
I have made it work in this way, but doesn't this method defeat the idea of DHCP, as I will now presumably have to manually maintain the /etc/hosts files on each device.
i'm running some virtual Fedora installations on a windows server 2008 with hyper-v. Most of them are Fedora 12 and 13. Everything works fine for some years. Yesterday i want to upgrade a F13 machine to F14 by netistall. The upgrade ran without any problems. After the reebot the machine was off the network. All the networkconfigs by DHCP are OK, IP address, gateways, DNS settings and so on. But the machine can't ping or connect to other hosts. I tried an VM from scratch with both F14 i386 and x86_64 - same ****. This is the first time i had such a problem by upgrading Fedora machines.
I often manually add a troublesome domain (e.g., advertisements, fake virus alerts, etc.) to my /etc/hosts file on Ubuntu 10.04 Lucid; but the effect isn't immediate.My hosts file is already fifteen thousand lines long (having combined all the hosts files I could find on the net, including the MVP one); but I still, almost daily, find a new irritant to add to my /etc/hosts file.My problem is I do not understand WHEN the /etc/hosts file is next read after a change.I've been rebooting to make sure the hosts is re-read; but there must be a simpler way.My question:
- WHEN is the /etc/hosts file reconsidered in Ubuntu? - Is there a way to have the /etc/hosts file re-read sooner?
In my home network I have two ubuntu desktops that are connected to a router. On each pc I have installed Virtual Box 3.2 and various OSes. I need to sometimes run multiple vm's at the same time which is very RAM intensive so I was wondering if there is any way to connect VM's on different hosts so that they appear they are in the same network? Various articles that show up as search results hardly pertain to what I want to do. Basically, I would like to make vm's visible in the network but on different hosts and with ip addresses that would reflect that those vm's are on a same network. Like ubuntu 1 has vm's a and b and ubuntu 2 has c and d. When I start all of the vm's, I would like them to connect to each other just like they are in the same network without "knowing" they are on different hosts.
