Networking :: Ip Masquerading With Mac Address Filtering?
Apr 30, 2010I 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 RelatedNetworking :: Iptables And PPTP VPN Filtering?
May 4, 2011I 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.
Ubuntu Networking :: OpenDNS Web Filtering Won't Work?
Jun 9, 2011I 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?
Networking :: Filtering Traffic On Network Interfaces?
Feb 8, 2010I am manually capturing and injecting Ethernet traffic (using lib_net/lib_pcap libraries) for an application. At the moment , both capturing and injecting are done on the same physical interface (e.g. eth0). The problem is that all the traffic that I inject, are captured again by my application causing an unwanted feedback of injected traffic. This caused that I had to implement traffic filtering when capturing traffic, which is consuming resources and eventually will become too complicated to support.
I have tried using virtual interfaces to separate the capturing and injecting streams, but that also presented the same problem as all the traffic from eth0 is forwarded to both eth0:1 and eth0:2. If possible I would like both streams to go through 1 physical device, using more PDs will be the last resort. I am also looking at using TUN/TAP devices to try and separate the two streams, maybe writing a user-space program that lies between the physical device and the TUN/TAP devices to do the routing of traffic.
Ubuntu Networking :: Parental Control/web Content Filtering?
Jul 29, 2010I 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?

Networking :: Iptables + Squid + Dansguardian - Boxes Will Act As A INTERNET Firewall + Filtering?
Jan 14, 2011is this possible on 2 Linux boxes will act as a INTERNET Firewall + Filtering: 1st PC = CENTOS 5.5 functions as a firewall using iptables with two NICS 1=ETH0 connected to internet with a public ip and 1=ETH1 with ip address of 10.0.0.1 connected to the 2nd PC Centos 5.5 with squid/dansguardian with ip address of 10.0.0.2
2nd PC = Centos 5.5 functions as a squid + dansguardian internet filtering with 2 NICS 1=ETH0 with ip address of 10.0.0.2 connected to the ETH1 of the 1st PC with ip address of 10.0.0.1 and 2nd ETH1=connected to LAN (172.16.1.0/24)
does this make sense? this might be confusing but I just want to try this, to protect incoming ssh from our previous Sys admins who intended to enter the LAN 172.16.1.0/24 network. And also to confuse them that they have to pass through 10.0.0.1 - 2.

View 1 Replies View RelatedCentOS 5 :: Pirut/yum: RHEL 5.1 - Maintain An Unregistered RHEL Box?
Feb 16, 2010A client has sent me an RHEL 5.1 box for me to do some work on, but it's not registered with Red Hat. This is causing me problems, because it's a minimal installation, and I need some more dev software.My immediate reaction was to install various bits (emacs, and so on) from my Centos 5(.0) DVD.The base RHEL system only had one (disabled) repo entry,so I added a yum DVD repo entry in yum.conf.d.
This looked good to start with, but it doesn't work. Something in RHEL's pirut/yum/rpm/whatever is getting confused, and can't work out what is/isn't installed.
Question - how do you maintain an unregistered RHEL box? Has RH done something to make life difficult? Is my problem simply that I'm using a Centos 5.0 DVD, instead of Centos 5.1? Am I stuck with downloading lots of rpms from the net and doing everything manually? I really don't want to do that.
Ubuntu :: Awk Not Except It Specializes In Filtering?
Jun 12, 2011I 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.

Server :: LVM 8e - Device Not Found Or Ignored By Filtering
Feb 3, 2010I 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?

Networking :: How To Install Rhel Through Nfs?
Jan 11, 2010I have two systems connected by local network 192.168.0.1 and 192.168.0.2 both installed RHEL
I have congigured nfs and httpd and /mnt/package contains the rhel dvd contents extracted. Also the iso image of rhel from the other system (192.168.0.2), I can mount the share from 192.168.0.1. i.e NFS network is ok in 192.168.0.1
But when I tries to install rhel from 192.168.0.2 It shows the message that that directory cannot be mounted. selinux is permissive in 192.168.0.1. The problem when it asks for network ipno.Is it required to run dhcp server on 192.168.0.1? I have tried another way also - by http created a link to /mnt/package in /var/www/html
But when I tries to install through http://192.168.0.1/package ( from http://192.168.0.1 also - experimented all combinations) - it automatically switches to CD install.
