Networking :: TCaR For IPCOP Not Registering Traffic?
Jan 18, 2011
I am running rooming accommodation for 5 students and am trying to use TCaR addon with IPCOP to split my 400GB Iinet internet quota 5 ways. As a total beginner to LINUX I am using the threads here to help me through the install/setup process. After following the steps in another thread http://www.linuxquestions.org/questi...-linux-752598/ I have IPCOP 1.4.20 installed and running (Advproxy,PUTTY, SSH enabled ect)and the TCaR addon operating fine on the GREEN. Everyones connection is working, however when I tried to send out usage reports after an hour of use it registers all persons usage as 0mb.
I am using a Billion BiPAC 5200 modem set to full bridge and a 5 port switch running without any modification. I had set the IP addresses in TCaR(not using MAC addresses)of the students and set their profiles to give 81920MB of usage per month. Usage is set to 1 cent per MB although I will not be charging for usage. Am I not waiting long enough for usage to register? Should I be changing settings on my 5 port switch? I noticed that the addon section of IPCOP is over 900 days old, is TCaR no longer compatible/supported? I can supply any further data with regards to my IPCOP and TCaR settings

I have a router running IPCOP with a 30 gig drive. I know the OS doesnt need that much space for a router. Can IPCOP mount and share out another partition on the same hard drive its installed on to my windows computers on my network?

I have a Fedora 13 desktop I have at work that I want to use to back up data off my laptop, also running Fedora 13. I can ping the hostname of the laptop from the desktop, but not the other way round. I don't think I did anything to have the laptop register its hostname with the DNS server. Since my company uses DHCP, I can't just edit the hosts file on the laptop. I want to be able to use the hostname when I mount the NFS shares for the backup. I also want to run the desktop headless so Remote Desktop needs to be able to find it. Is there a way to force the registration? If I ping the laptop's fully qualified hostname from itself, I get back the correct IP address. If I do the same thing on the desktop, it tells me it can't find its own hostname. I do have the domain name configured in the dns search path under System->Administration-Network

I have my home server set up as an ftp server, LAMP server, ssh server, all that fun stuff. I usually access it externally using my IP address, but I would like to get a domain name for convenience reasons. I wonder If you could recommend a site that will register a domain name for your IP, preferably for free. Or would I be able to do it myself by installing a DNS server on my server? I'm not really sure how that works. I'm pretty sure that you can only do that with local servers, right?

The motherboard is an L7VMM2 Rev 1.1Initially everything was running smoothly, then I brought it upstairs and everything just failed. The computer would hang right before the POST memory check, and after a few reboots it would do the memory check and reboot. So, I opened it up and switched the RAM around thinking it may have been a BIOS bug or a loos connection and it seemed to work. Now it boots into 10.04 perfectly and is blazing fast for an old computer. THe only problem now is that according to ubuntu, my ethernet controller is non-existent. It doesn't show up in lspci, dmesg and the only thing in ifconfig is the lo interface. It will however recognize the USB interfaces. I upgraded to linux 2.6.2.32-22-generic #33 but that didn't help the issue any. Now I'm stuck, and running out of ideas

I need to set up my centOS computer as a firewall in my home network. Ive got 2 interfaces, eth0 and eth1. I want to allow and forward all traffic on eth0 and block all traffic on eth1 except ssh, ping(icmp) and DNS. How do I do this? Ive tried some editing in /etc/sysconfig/iptables but no luck.

I wanted to tell my server to block all traffic but US only traffic. So i followed this guide:[URL].. Now I know, it's the best way to help prevent hackers/crackers (doesn't matter to me what they are called. I just have to stop them). My server only deals with US clients anyways so might as well just start right there for my server's security before getting into the brute force and injection preventions. So I got it all done compiled everything moved to the proper directory. I then started to setup my iptables. Like so
Code: iptables -F INPUT
iptables -F OUTPUT
iptables -I INPUT 1 -s *.*.*.* -p tcp --dport 22 -j ACCEPT
iptables -I INPUT 2 -s *.*.*.* -p tcp -j ACCEPT
[Code]...
After seeing that i went digging in the code and figured it was something todo with memory allocation.

Recently I notice that when I'm connected to an vpn server (pptpd) and I'm using it as a default gateway my download and upload speed decreases almost to the half of the usual speed. I made a test using iptables in order to count how much GRE packets are generated (except the real traffic itself) in that way:
Code:
iptables -I INPUT -p gre -j ACCEPT
iptables -I OUTPUT -p gre -j ACCEPT
iptables -I FORWARD -s 172.16.10.101 -j ACCEPT
iptables -I FORWARD -d 172.16.10.101 -j ACCEPT
The first 2 rules match all GRE packets between the pptpd server and client, and the next rules - the traffic between the server and the client.
When I turn the counters to zero and begin to generate traffic (to browse, to download etc.) I see that the GRE packets are even more than these in the FORWARD chain.
So, my question is first of all is my test correct and is it true that so much gre traffic is being generated during the browsing (it becames clear that the traffic is double than if the pptpd wasn't used as a gateway) and if yes - can that traffic be reduced?

I have installed ipcop v 1.4.21, and addons TCAR and Ipcop-Advanced proxy.Now i want a login script for users on the green interface. So that when they start using internet, they first receive login page (or even through a login url page), and if they are idle for particular time, they should disconnect automaticaly. and users can check their bandwidth usage and time usage on this page.

We have something on our network that is reaking havoc with our content filter. I am trying to track it down, but so far I have been unsuccessful. We have approximately 500 devices in 100+ different locations spread across 9 states. Looking at each computer is not really feasible.
I need a machine that can sit in between our network and our internet connection and graphically monitor in real time and logs how much traffic each device is sending and receiving. It would need to sit inline so it has to have two nics and be able to pass traffic. The machine also needs to be transparent. Reconfiguration of our routers or workstations is not an option.
I have used ethereal and wireshark before. Ethereal may be a viable option, but wireshark seems to provide lots of information, but no practical way to make use of it. how to set up the box to be a transparent device on the network that will allow internet bound traffic to flow (freely)?

I have a usb bluetooth dongle I've connected to my machine. The device appears just fine and using hcitool scan I can scan for device with no trouble. However blueman doesn't seem to register the device even when I force the applet to display and try add a new device it won't scan/see any of the bluetooth devices. Has anyone come across something similar or would know how I should proceed?

I just installed Debian 6.01a and when I click with my RAT5 mouse the clicks aren't being registered. This happens about maybe 40% of the time. There is nothing wrong with my machine physically and this is a clean install that is not virtualized. I've had similar issues with Kubunutu though blamed it on the virtual machine...now I know it's a Linux specific issue.

I'm wondering if it's possible to operate a Web Server 'without' registering a domain name, using an IP address alone.I currently have Apache & Tomcat running on one of my workstations. I am currently using these servers as development sandboxes; and I have P2P Search Engine 'YaCy' running under Apache, which is accessible from the outside to the entire P2P network.
Since my Apache server is accessible from the outside, I was thinking that I might setup one of my other workstations as a server with just my 'external' IP address & port number as a way of reaching my site, i.e. http:// 255.183.47.201:8090/. I can't see any reason why this wouldn't be possible. I seem to remember several of my former companies doing this on their corporate Intranets. Also, I wouldn't be locked into registering a domain name every year; and I wouldn't have to worry about any content restrictions. If my intended audience knows where to find me; I can't see any reason why this wouldn't work. And, I don't see why my site couldn't be indexed by search-engines. The only caveat I can think of is making sure I have enough bandwidth from my ISP to support the anticipated traffic.If this will work, I assume I can setup a regular website, an online store, podcast, or provide any other type of tradional web-service this way.

My external hard drive (about 2 years old) won't mount. It wouldn't mount on Windows either. Other external hard drives (sdb1) mount perfectly.
I am wondering is there a Linux way of getting the hard drive to work again? The disc spins up so it's not a mechanical failure. I'm guessing here but is there a way of flashing firmware onto the external HD if that might be the problem?
(Seagate 2TB ST320005EXD101-RK)
Code: Select all# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda2 during installation

I have a comcast business network adapter that has a 4 port switch. It also handles nat 1 to 1 translation for static IPs (That's just how they do it, there is no other choice).
In port 1, I have a cat6 that brings traffic to and from my linux machines, allows me to vpn, ssh, a mail server, etc. Everything here is fine.
In port 2, I have a netgear router that is setup with a point to point VPN for a client.
Here are the issues:
1. Machines that are connected to the netgear vpn router/switch can access machines on my network - I don't want this.
2. I can't access the machines connected to his lan from my lan - I need this to administer his machines somehow. Even if I have to VPN to the concentrator and do it like that.
Here is the network structure.
Code:
Internet <-> 10.10.10.1 -> switch with 10.10.10.x machines
|
-> internal vpn IP 10.10.10.50
|
[Code]....
The external network for the VPN is 10.10.10.x and the internal is 10.10.20.x. So, a machine with IP 10.10.20.100 can get to 10.10.10.X and I don't want that. I guessing it's doing this because technically, I'm 'from the internet' on 10.10.10.x and the vpn machines are going 'out to the internet'. Is there a way to have this:
vpn -> gateway traffic only?
I have a cisco 1811w at my disposal if I need to use it; however, I'm all thumbs when it comes to cisco IOS and networking in general.

I'm trying to inspect network traffic from my iPhone / iPad / Kindle / other wi-fi only consumer electronic device. To do this I man-in-the-middle myself (connect laptop to LAN via wire, create wireless Ad-hoc network, bridge the connections, then connect my device to the ad-hoc wi-fi network) and use Wireshark to watch the traffic.
In the past this has been adequate for my needs (just wanted to watch and see what potentially private info was being leaked about me / see that banking / amazon / etc apps were going over SSL). Now I've noticed that applications are almost all using SSL (which is great) but they are way to active for my taste. I'd like to use these apps but want to know what's happening in the background. I know that corporations dead-end SSL connections at their proxys to inspect the traffic and then re-establish the connection on behalf of the user for the trip across the internet. While I find the corporate use a bit distasteful, I think this is exactly what I'd need to do to myself. Any suggestions for how to do so or other ideas on how to get the packets in the clear?

I try to find somthing with ip tables, but can't find how to creat mounthly limits.PPTP do not have this option, maybe is some other, not hard for configure VPN server? Maybe someone make this task with iptables, and can give commands for limiting? Ofcorse VPN program with integrated accaunts and limits will be better.

I've got 4 or 5 of these TRENDnet USB network adapters ( TU-ET100c ) that I use frequently when I'm configuring firewalls or IPS devices for customers. I use them in combination with VirtualBox to test. They've always worked great until my new laptop I just got, and I put 10.04 on it. Previously I was on 9.x. Sometimes they will give a link light, other times not. And when they do the interface shows that it's up, but I can't get any traffic across the interface.

I have access to a VPN I use when having confidential instant messaging sessions. For the purposes of my work, essentially.I'm a command line kind of guy, and like to use Finch (the shell version of Pidgin) for those.However, when I turn on my OpenVPN connection it routes all traffic through the VPN. Web-browsing, IMing, and I can no longer access other machines on my home network.Can I set OpenVPN to only route traffic I ask through that connection (either by port number or application, or some way I haven't thought of), while other traffic flows through my usual home network?Some kind of local proxy perhaps? Or a dd-wrt box set up as a proxy, connected to OpenVPN?I've played around with the GUI environment too (I have a basic GUI I sometimes use on my main machine) and have installed the full desktop 10.10 on a second machine just to see if I can work it out.

I have a VPN account and have been running it perfectly on windows without any problems but I deleted my windows OS because I wanted to force myself to learn a Linux OS. I have installed the configuration package through the terminal and have followed this guide exactly
[URL]
The VPN was giving me a no secrets error to start off but I managed to fix and now it connects for about 40seconds but whilst it is connected, the internet is completely useless and I can't get on anything... It then disconnects after 40 seconds saying it has failed.
I installed firestarter to see if I could tweak it there to work but it was beyond me and I could also see from the data being sent that none of it was going through tap0 whilst the VPN was connected..

I have done some research on the net and I am battling to find effective methods in other to bypass those irritating ISP traffic shapers. I have used SSH tunneling to reduce latency (which is my primary goal, i dont care about silly torrents, etc) by about 200ms.
Do you know of any other way that I could improve this latency? When I ping my server in Germany (from South Africa) i get a latency of about 185ms... I was hoping to get online gaming traffic to around about 250ms or even less if possible... Right now its sitting on 550ms WITH SSH tunneling and 800ms without it... (to Blizzard servers)

I have a UBUNTU server 10.04 LTS with 3 network interfaces (eth0,1,2) with eth0 is connected to my lan and others connected to two different ISPs , I am looking for a very flexible and complete monitoring tool which can monitor all of the traffic of incoming and outgoing of any interface and SPECIALLY can show me which local client made connection to which interface for connecting to internet in online mode not offline and it is good to have online web base interface I mean the interface shows the measured data in real time mode. I fount some tools like iftop and iptraf and many others in this url: http://www.ubuntugeek.com/bandwidth-...for-linux.html but non of them are suitable for my net I mean none of them have good web real time data and non of them shows "which local client made connection to which interface for connecting to internet".
