I need to setup a box to monitor what websites users are accessing on a small network.I don't have a switch with a spam port, but I do have a machine with two nic cards. I would like to set it up between the router and cable modem so that users won't know it is there but it logs all the websites that are being accessed.
View 2 RepliesI am in the process of setting up my own Linux gateway/firewall using two nics eth0(external network) and eth1(internal network). The Linux gateway hands out ip addresses using dhcp3-server, and uses iptables to route the traffic correctly. Clients are able to connect and access the internet...everything is working great, HOWEVER I can't access my apache virtual hosts websites from the internal network? They work just fine if i access them from the outside world
I can type ip of the web server, 192.168.0.201 and it shows the first virtual host listed in my /sites-enables/000-default folder. but i can't use any DNS entries. I don't have any internal DNS servers running. This doesn't makes sense, because if i replace the linux firewall/router with my normal linksys wrt54G router it works just fine.
I want to monitor the websites that people in my network are visiting.It's a home network with various devices (PCs, phones, Ipads), and a ubuntu headless server. I'd like to install some monitoring software on the server, which would ideally provide me a list of website the devices (attempted to) connected to.Does such a software exists?? Can I control it via Webmin. Would setting my NIC in promiscuous mode affect performance?

Open a terminal window2. Enter the command sudo nano /etc/nsswitch.conf3. Change the following line:hosts: files mdns4_minimal [notfound=RETURN] dns mdns4to this:hosts: files dns4. Press Ctrl-X, Y, Enter to saveExplanation:Ubuntu ships configured to do name lookups for self-configuring networks, based on the AppleTalk / mDNS / Bonjour protocol. In the configuration shipped for the resolver, this protocol is considered the final aurhority for the ".local" top level domain, and DNS will not be checked. The above configuration change eliminates this and restricts lookups to (a) /etc/hosts file, followed by (b) DNS
View 1 Replies View RelatedI need to find a solution where I can monitor multiple sites at once and know when they go down. There are fraudulent sites (not mine I am in the infosec industry)
I have been playing with Nagios and Zabbix all day with not much luck. I have managed to get both installed and running and researched for hours. I just need to figure out how to add domain names to be monitored and I am stuck. I know you have to do it in the conf files but I cannot get a domain to show up?
I remember back when I used Windows, there was a shell command call "net view", which would allow me to see all the other users on my wireless net.
Is there any command or application that can do this? I dont mind if it is a terminal command either, but I would really like to know a way that I could see other users on my network.
I want to find out ip addresses and also mac addressed of users connected to the same wifi router as me! how can I do that?
View 5 Replies View RelatedThe question is related to one single desktop machine, with 3 users.
1) the superuser (me)
2) My elder son
3) My younger son.
As superuser, I can access the network (internet router) via "Wicd" perfectly well.
Both Client users can't.
Do I have to give them special user priviledges? If yes, which ones?
Have a strange problem with the network icon on my laptop.
I have two users (me & my wife). We often log in and use switch users so we're both logged in at the same time.
Whoever logs in first will get the network manager icon in the top panel, and whoever logs in second won't get the icon.
The second user does get a message (growl notification?) saying the wireless network <whatever> is now connected & it is indeed connected.
It's a bit annoying, as if I log in second, I can't chnage my wireless network to the other one we have, I'm stuck using whichever one my wife selected.

View 5 Replies View RelatedI installed ldap on my server and one of my client machines yesterday.It also now won't let me get into graphical utilities that require root privileges; synaptic for example. It comes back with "incorrect password". I noticed that in the terminal it now requires me to enter two passwords to become root: the root password and the ldap password. I wonder if the two are related.I'm not sure what information to post; there's a ton of configuration files associated with this setup. Can somebody help me troubleshoot this? Thanks!
View 8 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 been looking for a simple network monitor daemon for ubuntu, for some time but have not found anything that suits my requirements and from what i've been reading online there seems to be quite alot of other people out there that are looking for the same thing. [URL]...for-linux.html page seems to have the most comprehensive list of similar products but if you read through all of them they don't seem to be what i'd imagine most home users need. here's a list of what i had in mind, if any one uses something that has these features or knows of something that might meet these requirements please let us know! 1)a small lightweight daemon that can be accessed via the panel on gnome 2)has thee ability to monitor eth or ppp (particularly internet traffic)3)can represent this data in a human readable format ie using megabytes and gigabytes 4)can store a history of how much data is being sent and received over long periods of time (like several months)

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

9. — 217.197.12.0/24

i have recently had a house mate move in and he is using my wireless network, even though i asked him not to give out the network key to his friends either he has or they have hacked my network and are using it when they come over, is there a program i can use to monitor the number of computers that are connected to my network and block them, or is there a way i can just wee what is going on. They seem to just connect and i don't want to have to change the password particularly because that involves changing it on multiple devices.

I have installed Bind DNS server in Opensuse 11.1 and it was running fine for two weeks. However starting last week it was unable to resolve a lot of internet sites (e.g. opensuse.org). I can say it is working partiallyI tried restart the named service and it worked fine for only about 15 minutes and back to partial condition.All the records in zone files can be resolved. Only some internet websites not able to resolve. The same sites can be resolve with another dns server internally

when the server is getting overloaded with users. At present I run the server mainly as a proxy server with about 100 users. The bandwidth at the data centre is 100Mbps connection with total bandwidth used last month = 17431.16 MB
I would like to add a VPN in future but feel that this might overload the bandwidth as instead of it just being web traffic it will the entire client TCP connections. I would like to monitor this before it gets to the stage where users are complaining but not sure how to gauge whether the proxy is being overloaded. It is used mainly for video traffic.
I was having no problems (that I knew of) browsing the web since installing Ubuntu 10.10 a week or so ago. I was previously trialling Win7 as my customers will likely be using that in the future. Then I wanted to go to internode.on.net. Got the following: Quote: Firefox can't establish a connection to the server at internode.on.net. or Quote: Oops! Google Chrome could not connect to internode.on.net
As it was just after Christmas I thought it must be down, for upgrades or maintenance etc. I later tried to go to Freebsd.org; same error. I've been having a small number of other websites give the same error. I thought nothing of this until I tried it on my wife's macpro. I could log onto all the websites I wanted to and none gave any indication of having been down. Both boxes are on the same adsl connection. I still can't access internode or freebsd on 10.10 yet have been able to access every website on OSX. Now, I was only looking at them for info but am worried I won't be able to access something important. (so far everything I 'need' is working)
ping just drops out. edit: weirdest thing! I just retried and now can not emulate the problem for internode. freebsd still won't show. that is less than five minutes between problems and resolution! I hadn't even posted! But I still would like to have an idea of what is going on. Here is the ping error for freebsd: Quote:

I've just installed openSUSE 11.3 for the first time on a Dell E1505 notebook and am having problems connecting to my home wireless network. Using the Network Manager I've been able to find my home network and connect after entering the network password. After a minute or two the wireless network is still shown as active but their is no connection (websites will not load).
I'm completely new to Linux so I have almost no clue what could be causing this. I have tried connecting the notebook hardwired (Ethernet) to the router and get a perfect connection if that information helps any.
