I'm trying to block outgoing ICMP made by "user". I have user named as "foobar" and he/she shouldnt have rights to use ICMP/ping.ipt_owner works fine when I'm blocking normal TCP/UDP stuff. User can only connect to DNS, WEB and SSH.But still, user can use ICMP
#!/bin/sh
iptables -F
iptables -X

I have a problem which is a great inconvenience to me. I want to say that I've been searching for the answer for a week and couldn't find anything but problems similar to mine which were unresolved.I used to have debian lenny, but one day i decided to reinstall my operating system and upgraded to sid, so I have a fresh install of debian sid with gnome.
The system beep no longer works on gnome.
What I mean, when i move to terminal(like ctrl+alt+f1) it works great, it also works when i type 'beep' in gnome-terminal. but it doesnt make a sound when i e.g. press ctrl+G, when i am being called on irssi, when i press backspace in gnome-terminal. These things used to work in Lenny, and I really need them (especially this hiliting in irssi). I would go back to Lenny if i didnt need some software that is not present for that version of debian. The pcspkr module is loaded
I am setting up a virtual server. Ubuntu 11.04, "minimal provider image".UFW was disabled by default. I set it to default deny. Allowed HTTP, SSH and other standard stuff, and enabled it. All seems to be OK. Adding one rule to block some annoying security scanners causes ping not to work. I'm not an Iptables expert, but it looks OK to me. I got it from some website, rather than invented it myself, but modified to to fit the ufw config file syntax. What in that rule prevents pings?!? It seems completely unrelated.

View 1 Replies View Relatedi've come to replacement my 80 yr old fathers win98 machine with lucidFirefox 3.6.3 says 'connecting to .....' when accessing a webpage (eg his home igoogle page,bbc.co.uk ) and then times out .It all works with opera and links2 and pings are the usual times and its doing DNS . I've added 4.4.4.4 and 8.8.8.8 to /etc/resolv.conf for good measure FF its configured NOT to use a proxy ( Im fed up looking and checking !) and ive tried the 'detect settings automatically'this is a 'mission critical' step. Going to linux is a big enough change , so getting FF working will be a deal-breaker

I am installing in Kubuntu (I cant stand ubuntu anymore) But when i try to use dd to install to a USB, I cant because Ubuntu got rid of the root and when i sudo it, It doesnt seem to work!
Here is the message i get:
I have coriander-2.0.0-1.fc14.i686 installed and it does n t work anymore as it used to with my IIDC compliant ieee1394 camera.
I understood that raw1394 and video1394 modules are now deprecated. So firewire_ohci and firewire_core are loaded when I plug in the camera. There is no more /dev/raw1394 and /dev/video-0 streams, but now there are /dev/fw0 and /dev/fw1.
When I run Coriander, I receive: Erreur de segmentation (core dumped)
If I create the following link: ln -s /dev/fw1 /dev/raw1394

I have a computer that i wish to install ubuntu 10.04 on, it wont install tho, it tells me that it cant detect the cd rom (the drive it is booting from) and that i should insert a removable device with the drivers on it, except i dont have those and don't know where to get them. i cant boot from a usb but i have a usb with 10.04 on it just incase. i tryed this with both alternate install and desktop. i dont know what to do, i have invested 2 days to try and do this and i would really like to put this on my computer.
I have previously installed 8.04 on my computer with out such error and all of the hardware is the same (even the hard drive), and i lost the 8.04 disk. <(it was a live disk)
I am running xubuntu 11.04 (ISO from early this week). During install, I selected to NOT auto login but to present this gdm panel where I have to enter the password (or other users could log in).
Now I decided to enable auto-login (and to start the screensaver right afterwards) ... so I opened up the "login screen settings" (systems menu), unlocked that window and changed it to "login as xxx".
Then i rebooted and would have expected to be greeted with my screen saver on a logged-in session afterwards. But what happens is that there is a gdm panel sitting ... showing me
AUTOMATED login

Where the first item wont do anything.
So I have to select other and enter user name + password ?
Is that how it is supposed to work?
