Is there a hook thing in the Linux DNS. What I mean here is - in Linux hooks are called when the status of the network changed - like dhclient-enter-hook, exit-hook etc - is there similar thing when a dhcp client registers itself with the DNS?

FreeSWITCH ver.: 1.0.6
Client (Dual-Boot Setup) Problem: Both Windows Vista Ultimate 64-Bit and Ubuntu 10.04 LTS versions of Ekiga, including SFLphone in Ubuntu 10.04 seems to be ignored by FreeSWITCH. FreeSWITCH fails to register. In the client side, the Windows firewall gets turned off for testing while everything in iptables under Ubuntu has everything set to accept in the filter section. In the server side, the firewall configuration is quite basic.eth0: Cable Modem plugged in via USB cable eth1: nVidia Gigabit that connects to my 1Gbit switch

I have a question about GNU-PG security for email clients. I have read that this is the best email protection available. I have it among available Ubuntu packages, too, but when I wanted to use it the registration process asked my real name. considering full or the best possible privacy claim, why real name? or is it ok just not to give the real name? I am not advanced in cryptography, could/can this not be avoided?

I want to show line numbers automatically in bash scripts (a habit of being a programmer) and when I load an emacs lisp file it works from the command below but the following command that sets up the same thing for bash scripts doesn't work.

I'm running OS 11.2 with KDE4. I have to use the fglrx driver,as I could not get XBMC working with radeon or radeonhd. Well, fglrx works OK, however it does an automatic underscan on my LCD TV (connected via HDMI). So I reset this underscan to get rid of the black box around my desktop by issuing four commands in /etc/X11/xinit/xinitrc:
Code:
aticonfig --set-dispattrib=tmds2i,positionX:0
aticonfig --set-dispattrib=tmds2i,positionY:0
aticonfig --set-dispattrib=tmds2i,sizeX:1920
aticonfig --set-dispattrib=tmds2i,sizeY:1080
Obviously, xinitrc will not be called after doing a suspend2ram, but fglrx decided to get me back to underscan. So I tried to set up a hook:
Code:
#!/bin/bash
case $1 in
hibernate)
# Suspend to disk
[code]....
I get the exact same error messages, if I try to run the four aticonfig commands with "sudo -s" - however, it works, if I run them as "su".So finally coming to the question: Is a hook running with sudo privileges? Can I get it to run as "real" "su" ? Any other ideas (short of creating a hook that's logging me off, then on again?)

View 1 Replies View RelatedTwo tries at building mplayer. First time failed with no sound, second time worked fine - NO CHANGES that I know of, BUT OK - it works nicely.So if I click on a file in the Linux (fedora 14) file browser, I see using "Mplayer Media Player" as a second option, It does nothing, nor does it do anything from the Application tool menu. I do not know where the "I am doing nothing (and here is why)" error message is logged.
I can manually run mplayer or xmplayer on the .wmv file and it works.How do I edit the menus (control files?) and have them use the newly installed and working mplayer (or xmplayer??).Next, it would be nice to make mplayer the default tool to play videos in Firefox (the default for both is another tool (Movie player) which needs a plugin that I cannot find to work).And finally, if I can get one or both of these working - it would be nice to set the default to the new player instead of "Movie player".

I have a Linksys Wireless-G USB Network Adapter, 2.4 GHz, 802.11g. It hooks up through USB plug, and when I originally plugged it in I got the message that ubuntu didn't support the drivers, but haven't seen it since. I'm hooked up to a LAN cable right now, and can't seem to figure out how to hook up through wireless with this device. Or I just don't know how. When I click on the network connections button on the top right corner (the two computers). I can see my Wired Internet, but no wireless. When I type lsusb in a terminal I get : (sorry I don't know how to do code blocks) So it is recognizing that it's there, but maybe I just don't know how to use it.

I'm pretty sure I just need to remove the syntax I added to the /etc/gdm/Init/Default file and the /etc/kde3/kdm/Xsetup file and redo it (with less beer).

Is there another account built in that I could use or do I need to hook the HD up to a SATA - USB cable and edit the files from another machine?

I have a small home-office network. On that network I have two linux computers, one is a client the other a server.
On the server I have NFS Server setup and mount some NFS exports on the client computer.
On the server I have the firewall on and here it becomes a little tricky.
Since both the server and the client connect to the router the interface (eth1) is theoretically both an internal & external zone.
The router is commercial grade and therefore has a good firewall on it which is also setup. Therefore the firewall on the server is really more of a backup than a necessity. But that's fine, and by having the server's firewall on 'fail2ban' is able to work which I like to have working so I don't want to just turn off the server firewall even though I have good security from the router.
However, when I turn on the server's firewall, the client computer cannot see the NFS server when scanning for server -- done by: clicking on "Choose" next to "NFS Server Hostname" when adding an NFS share in the NFS Client in YaST. Clearly something is being blocked even though I have both "NFS Client" and "NFS Server Service" allowed in the server firewall. The Firewall config. files for these are below.
The Firewall configuration is pretty much "out of the box". That is I have the services I need opened up for the external zone, the other zones are left at their default which means the internal zone, although not used (i.e.: attached to any interface), is completely open.
The perfect solution I guess would be to setup my client computer to connect through a different NIC (perhaps eth0), make that the "Internal Zone" and therefore allow all traffic through to it while still blocking the server from the external zone. However, I cannot make that physical change to my network for now so I am looking for an in between (non-perfect) solution.
In this case I am guessing that means opening up extra NFS ports to the external zone so I have full NFS functionality. I don't mind this because like I said, the router firewall is the main line of defense anyway.
So, given all of the above could someone tell me what I would need to additionally open up in the server firewall to make the NFS server detection work on the client while the firewall was on. Or, if you have a cleverer/better solution without me changing my physical network that would be great.
Hopefully I have written this in enough detail and clearly enough so that all the parameters are clear but if not, feel free to ask me what you like and I'll try to make it clear.

My desktop is running 'buntu 9.10 and I have recently aquired a couple of half decent servers running Windows server 2003. I have a few windows app's that I use regularly for work that I have had limited success in running with wine or in vm's. I stumbled upon a how to to call apps in a vm to run seamlessly on the host desktop and did some playing and have succeeded in calling app's on my servers from my 'buntu desktop, the command I have set in my launcher for one of them (DIALux)
My question is, can I change the default application/file association in 'buntu with a custom command so I can double click on a file and have it open in one of these remote app's??If I can, what is the correct custom command to be using as using the above doesn't work at all, it just tries to open the file with rdesktop not the remote app.

what about deep packet inspection technics, is it possible to block my traffic?) but at exactly the same time I can transmit UDP packets using netcat from server to the guest. there is no firewall enabled in between, I had tried, tcp and udp, tried both open vpn and openvpnAS and tried any thing one can imagine! the VPN is configured as a routed (TUN) type on debian
