View 2 RepliesI am currently running a 64-bit Fedora 14 server which hosts a game server, a voice server, and remote desktop functionality, each on a distinct TCP port. I am currently using the built-in firewall to deny all traffic other than ICMP ping/pong and TCP traffic on those specific ports.I am looking for a graphical application which will let me monitor any connections being made to my server in order to keep an eye out for possible security concerns. To be more specific, I'd like to be able to see the source IP addresses, TCP/UDP ports, and individual bandwidth in use by external connections being made to the server, along with any other information that might be helpful in identifying a possible intrusion attempt.
View 3 Replies View RelatedI have a third party program (tightvnc) which I want to monitor and detect if it loses a connection with a client. I don't care if the client has the program open but isn't doing anything with it, I only want to know if the actual TCP connection is lost.
Since TCP takes forever to die on it's own I was thinking the best way to detect if a connection is lost is by bandwidth the bandwidth on the tcp port allocated to the VNC connection. Are there any tools built in to redhat (RHEL 5.2) which I could use to do this? Since I don't have full control of the operating system I would prefer to use built in tools rather then trying to get a new tool installed.
dear can someone highly gui or text base/command line tool that use as "isp bandwidth monitoring tools in linux".i do have leased line,frame relay, wireless linke,dsl too. i want to monitor what is uploading and downloading.

I have several machines that backup content to this server via scheduled cronjobs and I'm curious to see if the machine is hitting a bottleneck under load.I attempted to setup cacti on one of our LAMP servers and had a miserable time due to running PHP 5.3 and deprecated function issues.Can anyone recommend an alternative keeping in mind I have only very basic experience with SNMP?

I can use kppp to connect and get the logs I need but I want to connect to the network as soon as I plug it in - Only Network Manager allows this.
I have a home PC which connects through internet via a Zyxel ADSL router. I use Fedora 14 as my one and only operating system and sometimes I am seeing the LEDs of my modem blinking very fast which means that something is downloading. I want to know which application download what on my PC. Is there any tool in Fedora that can show which application uses my network?

Our primary sever is centos with WHM installation and hosts about 600 websites.(need to monitor mysql & port 80 on this.)The secondary one is windows server with virtuzzu installation and host about 15 windows VPS (The server crashing some times and we need to findout its out of service ASAP .)Should we use monitoring websites such as hypersins.com or siteuptime.com (which is a little expensive for us especially because of international sms rates.) or there is nice tools we can easily configure and use !
I have been using VMware Player for some time to host Fedora VMware images on Windows XP. I have been using Fedora 11 and 12 (both 32 and 64 bit) and recently started to use Fedora 13.
I use as a base the images provided by thoughtpolice. http://www.thoughtpolice.co.uk/
I usually install VMware tools and also keep the images updated (yum update) which sometimes changes the kernel.
I have recently had problems with the snapshots not having a network when I restore them. So far I don't have the problem with Fedora 11 and do have it with Fedora 12 (but used not to). I do have it with Fedora 13.
In each case the problem goes away when I uninstall the VMware tools and comes back when I install them again.
One of the symptoms is that SElinux complains about not being able to do something with /var/run/vmware-active-nics.
It looks to me that something is incorrect in the actions being taken when the snapshot is being restored. It does not happen every time and sometimes the network restores itself.
The network can be restored by rebooting the image.
I have a small office network with windows machines and a Linux Internet access server (CentOS 5.4). For Internet access I use masquerade, so everione can access every Internet service.
I periodicali have quite big traffic from one of the hosts, but I can't figure out which one is that?
Is there any linux command which will show me the bytes/packets (or any useful infos) going to specific hosts?
I was wondering how do you slap a packet analyzer like Wireshark somewhere between all the computers in a house and the router, so you can tell what websites are being accessed? I mean websites, specifically. I'm not trying to monitor bittorrent, IRC or other things yet - I'll get to that later. I just want to break this insanely complex task into smaller bites for now.Also, since my ISP has bandwidth caps but does not have a means for consumers to monitor total network usage, I'd like to figure out how to use Wireshark to do that as well. This, I am assuming, is easier when wireshark is running on the pipeline going into the router.

I am not so happy to say that they force me to use their "CTU", which is basically a Japanese router, which limits me from receiving external connections (such as would be required to host FTP, or administer my home machines via SSH or VNC). I have tried many methods of bypassing this piece of equipment, but so far none have worked (router setup for PPPoE, DHCP, Static IP, so on). I don't think the Japanese would mind me bypassing this device, as it's really there to 'protect' me, but there's such a language barrier that I can't figure out how to tell them what I want to do.
In order to troubleshoot the problem, I would like to setup a spare computer as a hub, dumbly (Is that a word? It is for this circumstance...) passing data from one device to the other, and allowing me to watch what is being passed via Wireshark. I am pretty linux savvy, but I'm completely useless with iptables.
Here is the final product I want:
After connecting eth0 to the fiber modem and eth1 to the CTU, I want the computer to duplicate eth0's distant end MAC to eth1 and vice versa (to simulate the computer not being on the network at all), then I just want the computer to pass any data coming in on eth0 to eth1, and any data coming in on eth1 to eth0. Finally, I need to be able to read the throughput with Wireshark, but I really think that will be very simple if I can get the rest of the setup complete.
One piece of info - there is no dhcp on this link of the network, and I have no way of knowing the MAC addresses of either end before connecting them.
As an added bonus, once I've captured the handshake between the CTU and modem, if someone knows how to retransmit those packets on demand (i.e. to replace the CTU with my computer), I would be quite happy to hear about it.
I just wanted to use a network bandwidth usage monitoring application. Scenario: I am using an EV-DO based USB broadband modem with a limited GB plan. For additional data usage they charge per MB. Currently I use either wvdial (mostly) or pon to start the connection. So if there is any network monitoring application which could log time used and data used for the session, it would be great. Actually debian has too many different network monitoring applications, But I am not sure which one suits well for this purpose.

View 9 Replies View RelatedNetwork/IT teams often look for a monitoring tool in reaction to a problem they have on the network. They know they have a problem, but they dont know specifics. They cant see, for example, who is hogging bandwidth. So they seek a free or open source point solution to solve that one problem. But if they already know one problem is happening, it's possible theres a second or third problem which could be prevented if the IT staff knew about these issues. An alternative approach to reactive monitoring would be to implement a robust network monitoring system before a problem occurs. An NMS should enable IT staffs to identify potential problems early on and solve them before end users notice them. Is your organization using a network monitoring system? If no, why not?

View 9 Replies View RelatedI was reading a magazine article today which was a discussion of internet detective work for tracking down ip addresses which attempt an ssh login to your machine. I have never really paid much attention to network security since I only run a small home network. I have WPA encryption and a firewall on my router. But while reading this article, I remembered that I myself has seen log files in the past that inidicated someone somewhere had attempted to log into my machine (attempts all failed). This had happened a few times, but I never really considered it a threat.
But, the more I read about home computers becoming "zombies" for criminals, I guess I am getting a little paranoid in my old age, particularly since my wife does quite a bit of business on the net with credit cards. I have four computers connected to the net and each other on this network, and would like to be able to easily detect attempted log ins and deal with them quickly.
So my reason for posting is to ask if someone could recommend a novice-friendly application for monitoring traffic to check this intermittently. I have read bodhi.zazen's excellent tutorial on snort, but I it appears to be written for large lan's or web servers and is over-kill for a small home network.
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?

My computer says the driver is installed and the device is present. All of that went fine. Now I need to connect my card to my house's wireless network. Am I supposed to do that in System-->Administration-->Network Tools? The problem is that whenever I click on network tools, the application looks like it is going to start-up and then quits/crashes/runs away, whatever. Any ideas on what is causing this?
Okay, I tried launching from the terminal, here is what I got:

I would like to test network performance, to get statistic information. Is there any tools where I could specify partikular message size send as a constant for many times and in an output I could get time for each transaction? There is a tool called ApacheBench, it is for webserver testing, but I would like to find something similar for network testing. I have also tried Netpipe, Netperf, Iperf, but they do not show information in an output, which I would like to see.
