I have a dell inspiron 600m with xubuntu 10.10 installed, I have it for a kids computer so I installed web content filtering (dansgaurdian) and I installed simple module for admin. dansgaurdian's control files (libdansgaurdian-perl) I instilled both from the USC. But I can't find where I can ajust the settings and on the web dansG is not filtering. how to find the gui part of it?
View 3 RepliesI've been trying without success for the past couple of weeks to setup a filtering system for my little sister's netbook. The main problem I've been running into is inconsistency. First, I tried using dyndns per the instructions here: [URL] The problem with this is the DNS settings (and in turn the filtering settings) dont appear to 'stick' once the Netbook touches a different network. So if I sign onto a different wireless network than the one I used to set up the filtering, it stops working. The reason why is Ubuntu will overwrite the current DNS settings with those of the new network (I have no idea why, and am too frustrated to figure out).
Also, I noticed that even if the settings did stick, they're fairly easy to disable because all she has to do is stumble across the DNS settings, change them back and voila. I've had great success with OpenDNS on Windows boxes, but there doesn't seem a to be a feasible way to apply it to Ubuntu. Dansguardian looks like it may be worth a shot, but I've seen dozens of "simple" configuration guides, none of which that actually looked simple. So my question is this, what is the easiest, most bulletproof way to setup web filtering 10.4? Preferably something that a 12 year-old could easier find her way around.
I am using 10.10 and am searching for a program to adjust the settings on my webcam. I am using webcamd to upload pictures to a weathercam. I can use Cheese for viewing the output but the adjustments made there don't stick when I close Cheese.
It appears there used to be a package called gqcam which may have done the trick, but I can't find it in the repositories anymore. There is a current tar.gz package available but I'm hesitant to use it since I don't know why it was removed from the repositories. Does it conflict with the recent video changes in Ubuntu and what conflicts could it cause now or when I attempt to upgrade?
Heres my question: Is there a program available for Ubuntu which will allow me to adjust the settings of my webcam or is gqcam still compatible with Ubuntu? Bonus points for a .deb package.
I have been unable to find the settings to enable or adjust compiz in Unity. I am so used to Gnome that this is almost like starting over.

Both, Desktop live CD / installer and alternate install CD cause the screen to go black (and the status LED blinks).
I was able to get a bit further into the boot process with nomodeset as parameter with the Live CD, unfortunately I can't pass GRUB any parameters now that I have used the alternate Install CD by pressing 'e', it just boots.
So now I have Ubuntu installed, I get a terminal with CTRL-ALT-F1 but I don't know what I need to do now or how to adjust resolution or video settings from command line.
I'm having some difficulty setting my txpower setting on my atheros wifi card. I am using ath_pci driver on ubuntu 8.1 64 bit. I can set the txpower to whatever, 12dBm for example, it accepts the change but quickly reverts back to a default value of 8dBm. Power saving is off. How can I make these changes permanent, or adjust the default value?

View 1 Replies View RelatedI did a recursive search using grep in a list of files for lines containing a specific word. It brought everything up ok but now I need to filter it out and print the results to a file with
* Path Name
* A section of the line
The path ends in a colon and after it could be any number of words, spaces, and punctuation which the one phrase I need being somewhere in there - I need the phrase to be filtered out and merged with the path like this
"path/to/file: phrase"
I'm guessing awk is the best way to do this but I don't know anything at all about awk except it specializes in filtering.

I am trying to block unappropriated sites on my ubuntu 11.04 with openDNS I installed it and in addithion to the catagoriegs I checked I also added some sites to the always block list, everything according to the site should work. But the problem is that nothing is blocked (also the sites in the always block list). I cleared the browsers cache but it didn't help when i try to clear the local cache with the provided command in their site I think it says it ignored my network.
About firefox,I want to block images only on facebook automatically so I added [URL] to the always block list in the images category and it should work but it just won't block the images. I should note that I use the same method on chrome and there it work like a charm. how to get that working on firefox?
I'm wanting to use mac filtering to restrict access to certain machines. I already know that I can just add MACs line by line, but is there a way to specify a list of MACs? That way it would be much simpler to maintain a list of acceptable/unacceptable hosts.
I'm not going to rely only on this list because of spoofing, but it would be nice as another "layer" of protection.
Let's say I have a few hosts on the same subnet, and they are all connected to a central Linux box running a filtering bridge. If I tightly control the communications between the hosts using the filtering bridge, is this just as good as seperating hosts into different subnets (e.g. DMZ and Internal) ?

View 3 Replies View RelatedI'm in charge of a church computer lab which is open to children ages 6 to 16 for about 3 hours a week. We try to have adult supervision but don't have 100% coverage.
The lab has a maximum of 8 computers, a mixture of MACs, Windows XP, and Linux machines, depending on their state of repair.
The church's current internet connection is Verizon residential speed DSL to a 4 port wired plus wireless router in a locked office which also houses our Windows XP office computer and is adjacent to our locked pastor's office.
Internet access for the lab is by a single CAT5 cable passing through a small hole in a wall to a network switch on the other side. All of the lab computers are connected to the switch by CAT5 cable.
I would like to add a server in the locked office to log internet usage and block access to certain websites as needed. I think logging internet activity will be a good antidote in case one of the older ones wants to try to get sneaky and cover their tracks.
I envision building a computer from donated parts, including 2 NICs.
I have never done things from the server end, but think the server edition of Ubuntu would be a good starting point.
My goal is to be able to manage internet access with an easy to use GUI system so I could teach the basics to a couple of youth leaders to use it when I'm not there.
I work at a cybercafe and i am currently plagued by users who, despite the warning not to, continue to watch porn and use p2p software on my connection. I have done some preliminary research on how to filter the web content as well as to reduce the bandwidth used by p2p software on my network. I found that a solution that has worked for many with regard to web content control is danguardian + squid or privoxy in conjunction with a firewall like firehol or something of the sort. Others use an os like untangle or clear os and install it on a stand alone server. then others use open dns. although i would like the open dns solution, i will need to install a dns client, ddclient and i am a linux newbie so and ddclient requires some compiling or so, and i'm not yet into that. I am also currently not in the mood to dabble into untangle or clear os bcos it will cost me a lot do download the iso's. Internet access is costly over here.
Before i go ahead to implement the steps in any of the tutorials i have seen, i am wondering if such a measure will even help at all.You see, at my cafe, i use my server to share the connection to all my clients. I connect to the internet using a gsm modem. then i have two nic's. nic1 is set to share my connection and my router connects to that nic1. nic2 connects to my router using a static ip to enable communicate with my clients. If i implement something like dansguardian on my server, will it solve the problem for me, that is, do i have to also re-implement the steps i took to configure dansguardian on all the other pc's, that is, my clients?

View 3 Replies View RelatedI pay for wifi usage. The access points are using mac address filtering. I know this because I can spoof the mac of another computer of mine and get it online. I'd like to get both the computer's online. I've been trying to do ip masquerading. It hasn't been working so far. I am not sure if the computer connected to mine through a cross over cable is revealing its mac address to the access points when communicating. If so, how does one get around this? ping shows connectivity between the two computers.
View 4 Replies View RelatedI have a question regarding the use of iptables as sort of a firewall I suppose? Using a linux router which has a server machine connected to it. The router is also acting as a PPTP VPN server, which I would like to allow some friends to connect to so that they can VPN to my LAN.
The question I have is how I might be able to use iptables to apply restrictions to the VPN traffic to only access 1 IP? The server is on the LAN with an IP of lets say 192.168.1.25, and the VPN given IP range is 192.168.1.51-55. The router has the .1 IP, but the PPTP server on that router uses an IP of 192.168.1.50. How might I restrict the traffic from the VPN connections to only be able to access the .25 server, and possibly only on certain ports? I don't want to allow the VPN connections full access to everything on the LAN and especially not to WAN.

I have made linux raid array, named it md1 and it can be found under /dev/md1. I have created single partition (whole disk) of type LVM (8e) and it can be found under /dev/md1/md1p1.
When I run: pvcreate /dev/md1/md1p1
I get this message: Device /dev/md1/md1p1 not found (or ignored by filtering).
But if I run pvcreate /dev/md1
Everything went OK. I can create volume group and logical groups after that.
I haven't found anything specifically on net, except that partition for LVM to work should be of type 8e. Does this doesn't have to be true when we use whole disk as a VG? Should I expect any problems since this is going to be iSCSI target disk?
Is there any way to filter the output of a command based on the values on the output columns. For example i execute du -h on directory with many files. Now I want to filter the output based on the size (i.e. M or G or K ). The filtered o/p should contain only M(megabytes) or G(gigabytes) and also all columns.

Is there some way to filter output of command by OR condition in Linux? There is filtering by AND condition with grep in way like:
ls -l | grep "^a" | grep "z$"
That says: list all files that beggins with "a" AND ends with "z" (so there is shorter way to write this: grep "^a.*z$", but it is not matter). Is there some way to perform test by OR condition? For example: files that starts exactly with "xen" OR files that ends exactly with ".rpm". But exactly, not something like:
grep "[xen]{0,3}.*[.rpm]{0,4}"
how I cat to filter out information about Unix Domain Sockets from netstat output without grep? Is there some option for command (I not found it in man of netstat).
