I would like to be able to monitor which programs are allowed to access the internet, but a search for programs to do this has turned up nothing. Preferably, I would like a notification to come up every time an application uses the internet. Is there any (n00b friendly) software available to do that?
View 2 RepliesWe 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)?
As I view it, Ubuntu has a great security risk in that it still allows internet access when the VPN connection has been lost, for whatever reason. As it is now, when the VPN connection fails you get bumped back to using your regular IP, and whatever you are doing becomes transparent to anyone watching. This is simply unacceptable for an allegedly secure platform. Does anyone know of a way to fix this with a script/program, or is there a distribution/OS that allows this? Windows re-dials the vpn automatically, but still allows internet access in the mean time.

Currently I'm using iptraf, but it's very hard to understand at times.
A little info on my network:
I'm using SNAT for internet sharing.
I have a 2 machine LAN with both machines having an ethernet card and a wireless card. There is a Netgear router, both eth and WiFi, allowing both machines to access the internet.
On my Linux machine I am looking for some software that allows me to keep track of my broadband usage on that machine, excluding traffic between the two machines.
There are numerous such programmes for this in XP, which use Winpcap and a GUI frontend. The "other" machine on my LAN is XP and uses just such a program.
I installed 11.3amd64 as a VM under Vista/VMWare Player - all worked fine. I have now installed it as a physical system. It nstalled cleanly BUT during first boot it could not access the repos. With each repo it gave the message
- download (curl) error for (repo)
- error code connection failed
- error message could not resolve host (repo)
This was followed by a message box containing
- UI syntax error
- no widget with ID 'contents
Firefox could not access the internet (cannot find server) until I disabled IPV6 (I used about:config), now it works fine. I think the repos problem is because of IPV6 - I usually have trouble with IPV6. I tried disabling IPV6 with the following (How To Disable ipv6 on SuSE Linux | Linux Poison)

I am on a slow Internet connection and it really makes me mad if something gets downloaded in background (like automatic update of any software) without my knowledge.
How can I monitor my network traffic sorted according to the "which binary file is using how much"? I can find the total transfer rate in "System Monitor" in Gnome, but what if I want to find for individual process. There are softwares like netmonitor in Windows, but how can I achieve that in UBUNTU LINUX.
GUI application will be nice, command line software will also be fine..
Is there an easy way to monitor network traffic? I want to make sure my kids are surfing safe...
View 5 Replies View Relatedwhat I want to achieve is just to be able to say to who ever is killing our relatively fast connect that they aren't the only person using the network. Everyone just says "I hardly download anything." which is obviously untruthful as normally I can download at 1.5 MB/s but now loading even google.com takes way too long (same with pinging and all other sites). Once I do this, I can determine whether or not I need to call my ISP and do the long 'on hold' dance and "have you tried rebooting the router" BS.
View 8 Replies View RelatedI 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
is there a utility with which I can get the current traffice towards a given host, for example;
command 87.255.33.32
22000
I need a simple traffic monitor for Linux, that counts the traffic in a specific wireless network because I have volume restrictions on that one.I tried it using the following iptables rule:
[code]...
iptables -m mac -A INPUT -p all --mac-source <mac-address> ! -s 10.0.0.0/8
where <mac-address> is the router's one. 10.0.0.0/8 is the local subnet. What I actually want is something like --routed-through <mac-address>. Also, is there some way to gather iptables's statistics? Or is there maybe another tool that does what I want (reliable)?
Is there a network trouble shooting guide for OS 11.2 that I could follow? I've shot myself in the foot so I should try to fix it.
I changed the DNS server addresses and the number of IP addresses on my router. I then set my Linux system to use static IP addressing and edited the network settings for my network adapter accordingly. I can now no longer get to any web-site.
By contrast, I also updated 1 of my Windows computers in a similar way; it continues to work without problem.
I am trying to get internet connection on Open Suse 11.2 through my wireless connection. I can connect to my network but there is no internet connection. The internet connection does work with other Linux distros and with Windows 7 laptop and Windows XP machines. I tried turning off the firewall but still no connection. What is even stranger is I can ping Google but in Firefox I cannot go to Google.

View 3 Replies View RelatedI am connected to a network with free traffic inside it and post-paid outer traffic. So I need a way to be able to separately monitor the download traffic from inside and outside the network. All the solutions I`ve found for now offer monitoring of ALL up/down traffic.
So, I want to get separate statistics on these:
1 — 81.89.188.0/23, 217.197.9.0/24
2. — 81.89.186.0/23
3. — 81.89.178.0/23
4. — 81.89.176.0/23
5. — 81.89.180.0/24
9. — 217.197.12.0/24

UPD: I`m connected to the internet through the network`s gate, so all the traffic comes through eth0. I wish to separate traffic incoming from the IPs on top from all other traffic
OpenSUSE 11.3 x64 KDE I dont know what happened it is a new install thats been running for 2 weeks . Now for some reason I can not access the internet or the router. Samba is working with Dolphin I can browse shares on local network both Windblows and Linux and ping local IP's. But I can NOT ping my router (the default gateway IP) with this box or access it with firefox so no internet. A VirtualBox of XP Pro running on this box has no problems with its bridged adapter getting out and seeing the router. I disabled the firewall, added gateway IP to network settings, disabled ipv 6 from the get go, added service provider dns's to nameservers tried opendns servers also.

I just did a large patch on my opensuse11.3 system (upgrade of all installed packages), and whilst my network interface works, I cannot get past my router onto the internet.
I can connect to other computers on my network (here at home), I have an IP address via dhcp from my router, but I cannot get internet access, either from thunderbird, firefox, or simply by [URL] Clearly the computer was connected to the internet just fine minutes before since I did the large patch! Also, my other computers CAN still connect to the internet.
how i can debug it? It is just too coincidental I have upgraded everything and now somethings amiss!
If it's relevant, my router is a netgear WGR614v9.
A few things I've tried...
Code:
linuxthinkpad:/var/log # /sbin/route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 eth1

loopback * 255.0.0.0 U 0 0 0 lo

I have a linux firewall. I want to limit a ssh connection number from local network to internet .
Example :
Internal pc (192.168.0.10) start a ssh scan to the external (internet) host.
I want that iptables limit that host (192.168.0.10) and block ssh connection from this host at 3 attempt.
recently ran into a problem with my internet access. Im using open suse 11.2 on a Dell Vostro 1520 laptop. I managed to get my wlan running and i can use firefox to access my router.

View 3 Replies View RelatedI need to implement at my sister this kind of connection: She is connected on Local area network that has about 50-80 pc's, but for internet access she must start an pppoe connection. For now when she wants to use lan she must put her local address (ps: they dont have dhcp), for pppoe she uses dhcp. Problem is that on that way she can't access lan and internet at the same time. She must disconnect from lan and then start pppoe connection and vice versa. I'm intrested if it is possible to have lan access at the same time as internet access. some kind of tunel through lan up to isp. I was googling little and so PPPoE tunneling. Is it that what I need here?
View 9 Replies View RelatedI have the Shorewall firewall running on Ubuntu 10.10 server and the issue I am having is the firewall is blocking traffic from my transmission-daemon even though I have allowed it in the /etc/shorewall/rules.

as you can see, Shorewall is rejecting packets with source and destination port 51413 on incoming net2fw and outgoing fw2net even though the rules are set to accept.
I've been running Suse 11.2 KDE on a 64-bit Dell Studio 1535 since last week's release, and have had no trouble using Firefox. At some point today, however, it stopped accessing webpages -- or, when managing to grab a page, it would do so without full html rendering. 95% of the time I get an error splash, while the other 5% I get some sort of truncated page that looks nothing like it should. Konquer and Opera work fine, as does KMail.
I tried deleting the profile.int file (no luck), then uninstalled/re-installed (no luck), then uninstalled and deleted every Mozilla/Firefox file I could find in order for a fresh install -- but this has not worked after several attempts. I still cannot get Internet access. How to completely wipe-out Firefox in order to allow for a totally new installation?
I just upgraded from Suse 10.x to 11.2. Unfortunately, I didn't use 10.2 much and I('m a bit overwhelmed by the upgrade. Any advise is greatly appreciated.
After my upgrade, I lost Internet access. I don't really know my way around too well, but I did try to ping my router, but had no success. (Although I can ping 127.0.0.1).
I'm guessing that this means network access is not configured, although it looks OK to me.
Recently i started going into OSes other than Windows. So, i installed openSUSE 11.3 32bit on my system in dual boot with Windows7 32bit. Everything was okay But i couldn't find any drivers for my laptop. My problems are :
1. cannot access NTFS drives.
2. cannot connect to the internet through LAN
3. cannot connect to the internet through Wireless.
Computer's Configuration :
Dell Inspiron 14r
Intel Corei3 processor
Both the operating systems run fine otherwise
I'm trying to setup a wireless AP with my old asus eeepc, so it can act as a repeater to connect my android device on the other end of the apartment. I've already created the Wireless Access Point using hostapd. It took very little configuring, just changed from mode 'a' to 'g' and changed the channel from 60 to 1 and It was all set. Next I setup a dhcp server. Also simple enough using yast.
Up to this point, I was able to connect my android device to the newly created wireless network. However It doesn't have internet access. I guess I have to configure iptables for this, but I find it incredibly confusing! Here are a few specs to help with any examples: The laptop is connected to the internet through eth0 with IP 192.168.2.120 Hostapd is using wlan0, and I'm pretty sure it created mon.wlan0 So, to sum up, when I connect my android device to the network I can, for instance, see what ever pages apache is currently serving on the laptop, but can't access the internet.
