OpenSUSE Network :: Regulate Internet Usage - Blocking Downloads?
Feb 18, 2010
We are switching from an uncapped 512kb line to a 4MB line at the office... One catch though. The 4MB line will only be linked to a 30GB account, without the option to top up. I therefore have been asked to put something in place to regulate what the staff download at work. Basically block movie, music and torrent downloads should be sufficient, but they would also like to have a list of where staff have been in case of abuse. I have tried OpenDNS in the past, but the guys took great delight in getting around this, and did it within minutes... I can't enter a proxy setting into their browsers, because they all have local admin rights on their Windows boxes and will just disable that. How do I do this on a server level, so that they can't get around this?

How do I find out the network usage ie the total amount of data is transferred in or out of my computer (openSUSE 11.2 and gnome) and keep a track of the total network usage?

As too my question, at this time I dont control the router/firewall an I would like to block a port thats used for guild wars on my workstation for a while. The reason for blocking is children have abused it an lost it.In this case I am trying to block outgoing traffic on port 6112. I have tried setting up a proxy server on the workstation, but the game seems to ignore it an jump on. Due to the environment, I enabled the workstation SuSEFirewall2 firewall an tried setting up "lo" as a internal an configure the firewall as a router, then disable 0/0 an configured for 0/0,tcp,443 an re route port 80 traffic to proxy.
When I had my own internet, I had a transparent proxy enforcing rules for access times. So setting up a proxy on each machine would not be a bad thing, even if it took some creative thinking. I am trying, but seem to be missing something.Ideally, I would like to setup a transparent proxy, as my kids have learned alot about system administration an know to check the proxy module. If all they have to do is un check "Use Proxy" an by pass a local proxy server, then I am kinda defeated. An applications such as firefox have a proxy setting they could set to none instead of system

My wireless usb network adapter is constantly using ~100bytes/s even when there is nothing I can think of that needs to talk to the internet. Is there a way to find out what programs are using the internet?

Ok here's my setup :
SuSE 10.0 X86 32 acting as my internet gateway and firewall.
eth0 is my internal interface network 192.168.0.0/24 IP 192.168.0.254 dsl0 is my internet connection and is a single ip PtP connection to my ISP.
My internal network is masquaraded onto the external network.
I run an smtp server on my gateway box that I need to be accessable to both the internal and external networks.
However I want to prevent machines on the internal network from establishing connections to external smtp servers, but still alow them to connect to the smtp server on the gateway to send email.
NOTE I do not want to force attempts to connect to [URL] 25 to be re-directed to my internal server I just want to drop or reject the connection.
The firewall up until now has just been configured through YaST, but am not afraid to edit script files if needed
The reason for doing this it to prevent spambots from being able to send through my isp, I keep my own machines clean but sometimes get asked to disinfect machines for other people (family members etc), where I need to connect to the outside world to get updates/virus defs etc, but don't want them spamming from my network.

I've setup vnc over ssh tunnelling however the Suse firewall seems to be blocking it. On the local host I have this in ~/.ssh/config:LocalForward localhost:5900 remotehost.com:5900 The problem is that this only works when I either disable the firewall or add an exception for VNC. Both of these actions defeat the whole purpose of ssh tunnelling since they leave my VNC port open to the outside world (very insecure).

My home computer has 11.3 and SuSEfirewall enabled. It connects to the net over the wireless and SuSEfirewall has this connection in the external zone.
I can successfully ssh into this computer from remote (the work computer) but none of the ssh port-forwarded connections work. I'm trying to tunnel VNC over ssh. I also tried setting http on the home computer to serve pages on a high-numbered port (8090) and tunnelling that but it also didn't work - proving that it's not a VNC problem.
Here are the relevant messages from the firewall logs on the home machine:
Code:
I don't understand why this isn't working now, I had the same setup on 11.2 and it worked fine.
The 95.91.92.92 is the public IP address of my home router, I don't understand why a connection would appear to be coming from there when I use ssh-tunnelling?

Printer is connected via USB to server PC running OpenSUSE 11.1 Client PCs are running 11.1, XP, Vista No problem printing from the Windoze machines
Printing is trouble free with the 11.1 client's firewall disabled, but no printer is available with firewall running.
In hopes of diagnosing the problem I figured I'd open everything I could think of until the printer remained available with the firewall running. Then I planned to start removing exceptions one at a time 'til removing one caused the printer to disappear.
I've gone to Yast>Security and Users>Firewall>Allowed Services>External Zone and tried addingSamba Server

I have a remote network that I manage consisting of a DLink DFL-210 firewall/router, and behind that a Dell server running openSUSE 11.2 and a collection of Windows XP/Vista/7 computers.
The Linux box is running OpenVPN as a server (that is how I connect to this network) and a client (it connects to a second server - running XP - at a different location).
The DLink router is the DHCP server and provides addresses on the 192.168.51.0/24 network. The OpenVPN server provides the 10.8.51.0/24 address range.
The remote network that the Linux box connects to is 192.168.54.0/24 via the OpenVPN network 10.8.54.0/24.
I have added routes to the DLink router to route all traffic to the 10.8.51.0/24 and 192.168.54.0/24 networks to the Linux box.
With SUSEFirewall turned off, after I have connected via OpenVPN from my remote computer I can ping all active 192.168.51.0/24 addresses. Other computers on the 192.168.51.0/24 network can ping computers on the 192.168.54.0/24 network. But if I turn on SUSEFirewall, neither of these work. However, I can ping 10.8.54.1 from any computer on the 192.168.51.0/24 network.
How can I set up SUSEFirewall to allow these networks to communicate with eachother?

It should give me daily internet usage stats something/vaguely like this:-I have tried ntop and darkstat ,but they were too complicated and cannot be launched from notification area like this..Also tried using KtrafficAnlyzer by installing KDE core, i am not very amused by the idea of having to install a massive run time file package for a simple tool.

I setup a server with vmware esxi 4. I installed opensuse 11.2 and I have successfully setup an internet gateway and I manually configured (static) my client IP. My question is, is there any software or commands that I could use to manage the bandwidth usage for each client? eg. only 5Mbps for 192.168.1.5, 10Mbps for 192.168.1.10, etc

OpenSuse 11.4 Asus Netbook 1000H Following other members in the forums I have installed Opensuse 11.4 on the Netbook. In the early days Ubuntu Netbook Remix worked well for me. But this has been discarded, and the "one size fits all" Ubuntu had become slow and cumbersome. So..... onto my post. Opensuse is working well. The install went beautifully.
It detected the Wireless Internet and I am able to get on line. I also need to share the Internet connection to a desktop. This is done via a small network switch. Thus far I cannot do this. I tried to use ifup to configure a static ip but this busted my Wireless configuration. I went back to knetwork manager. Then I tried to set up the wired network using knetwork manager and under IPV4 "share" the connection. But this blanks out any possiblity of a static address and substitutes dhcp. My desktop cannot ping the this dhcp address. Ubuntu had this thing called Firestarter? - from memory. This configured the system to sharing the network.

I installed Suse 11.2 on clean HD. I cannot connect to the internet. Seems like Suse didn't install drivers for on board ethernet card. It is a Marvell Yukon 88E8056. I'm new to this and don't know how to install the drivers.

I have SUSE 11.0 set up to act as a router/firewall for my home network to the internet through a cable modem attached to an Ethernet card. When I was laid off several years back, I found information that let me connect my network to an ISP via a standard serial modem. I am considering going to the Sprint U1901 4G USB modem and dropping cable internet. Sprint claims the U1901 is Linux compatible. My thoughts are that using the 4G modem should be similar to the old dialup modem. I had a script that connected to the internet whenever internet traffic was detected. Unfortunately, I did not save notes on what I had done to setup the modem to dial automatically, and I have been unable to locate information that seems good to set this up again. I already know that all I had to do to get routing working was simply replace the internet port in the firewall/routing script with the port for the modem. So I assume that is rather trivial.
Would you please point me to a doc, perhaps SuSE specific, that gives reasonable directions on how to set up a "dial on demand" ISP connection? I assume that the 4G modem will be very similar to my old serial modem so that a dial on demand script will work. I did find a dial on demand howto, however, it did not seem to apply.

In short: browsing the internet with domain names does not work. The long version: I've configured my network with DHCP and ifup. Ping works on my internal net and with servers in the internet. Dig work's too! I get the right IP to the requested domain. When i try to access the internet using firefox or even wget i get an DNS error. For example wget is showing the following error: Resolving heise.de... failed: Name or service not known. wget: unable to resolve host address 'heise.de'
Again dig show me the right IP and if i add the entry to /etc/hosts it work's too! I've even tried it with manually setup of ip address, nameserver and default gateway but with the same result. Switching off the firewall has no effect on this problem, too.

I'm on opensuse 11.4 (11.3 won't work with my monitor).
My computer gets internet through wireless and I want to share that internet through its ethernet port. So far I've tried using Knetworkmanager to create a network bridge between my wireless and wired connections. I created a new wired connection and shared it using the ip address settings. I was able to get both connections active, but the device hooked up via ethernet had no internet connectivity.
I also tried this command:
echo 1 > /proc/sys/net/ipv4/ip_forward
but another test resulted in the same fashion (no internet on wired). I believe anything I add to /proc should have an immediate effect, correct?

I have a desktop computer running OpenSUSE 11.2 with two network cards installed. I would like to use both cards for connecting to the internet using different networks. The setting would be the following: eth0 is the main (default) card, almost all programs should use this NIC for connecting to the internet. eth1 is used only by a few programs, which have setting for selecting which network interface to use. The two NIC's are connected to different networks, so the IP address of the NIC's, the related subnet masks and gateways are also different.
Saying short, I would like to have the two NIC's as they would be in two separate computers. I can set the IP address and subnet mask of the NIC's. The main problem is that I can only declare one gateway. How can i setup this? I do not use network manager, I configure network cards using yast, but if needed I can of course use ifconfig directly.

I'm having a strange problem with my network connection/DNS. I turn computer the on and it recognizes and connects to wireless or wired but I can't access any Internet resources or my router. If I ping the default gateway, I get no response and I get DNS errors from any network services that run at start up. If I stop and start the network daemon then it all works fine until the next time I turn on my laptop. It does this for both wireless and wired connection.
I've tried to edit the network interface information in YaST but it says that configuration is handled by knetworkmanager and I have no idea where that information is accessed. I should point out that it all worked fine until I tried to connect to open WAP at my school and couldn't so I connected to the wired network. Next morning I had this problem when connecting to my home network. My questions are 1. What could be the cause of this error and 2. where does one configure the network interfaces when using knetworkmanager

I often use an Ethernet cable to connect my computer to another computer for various purposes. But when I do that, I cannot use the internet even though I'm still connected to a WiFi access point. I'm presuming that's because openSUSE is trying to reach the internet through the Ethernet cable, which has precedence over WiFi.Is there a way to enable internet usage via WiFi while I'm connected to another computer over Ethernet?

I have no Internet Access with Firefox
I first tried an upgrade from 11.3 to 11.4 and lost Internet Access, so i re-loaded 11.4 from scratch on clean partitions.
I am connected to my wireless WPA2/PSK connection, have an IP, am able to see the network.
I turned off and disabled the SUSE firewall.
I tried setting Firefox proxy settings to auto and to none, i dont use proxy.
I am currently posting this through an SSH connection to my 11.1 server from the new install of 11.4 on a Dell latitude D600 laptop (not using the on-board Broadcomm that is an issue for a later date).
I am running out of ideas anyone got a clue.
