We are a small company running half a dozen servers in data center.Recently we got charged heavily for over-utilizing the data transfer. So,we are looking for a way to find - uploads and downloads per ip and port basis.We have mixed environment (Win2008/Ubuntu) so the tool should be able to work for both.I am not sure if MRTG provides per port(i.e. application) based analysis.
View 4 RepliesI have Debian and want to be able to connect to an ftp server, download some (or all) files, disconnect from this server, connect to another ftp server and upload everything on it. (And delete the temporary files on my PC). This should be done form the command line. I am no expert in linux (although I am acustomed with it). How to do this (or part of the solution ). In the end I would like to write a script, that mirrors my site from 1 place to another.

View 1 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.
Sometimes I notice that there is high upload speeds for 10 minutes or so. At the time of the screenshot I was sitting in a public wireless place, only chromium was open and I don't see any reason why there should be sustained upload speeds.Is there a GUI or CLI so I can find out which process uses the internet?

So when Im uploading,(ftp) IE using a lot of the network "space" the other computers on the network gets kicked out. So what is going on? My Airport Extreme is doing fine, but my other clients just get kicked out. If I pause the upload, everything is okay again. The whole network is 1 gigabit, clients, everything.

Transmission says my port is closed. If I google the problem, it just gives me advice on how to open a port in Windows OS. There's no firewall in Ubuntu 10.10 by default, right? There isn't any router used neither. I'm living in a dorm. I just plug the LAN cable in the box fixed to the wall.

Is there a way in Linux to give a specific application more/less priority for network bandwidth? Something like how nice does for CPU priority.
Context: I'm currently on a very low bandwidth connection (3G dongle). While I'm performing a quite large upgrade using aptitude, it becomes virtually impossible to browse the web since the upgrade download is hogging my Internet connection.
So what I would like to do is somehow decrease the network bandwidth priority of the aptitude process (and all its children) so that it won't use too much bandwidth while another process is using it.
I need a serial port monitoring software that works on windows 7 64bit or GNU/Linux and supports at least RS-232. Bonus points are if it's free software or at least freeware. I just need to be able to see what goes in and what goes out of the port. At this time, I don't need any protocol deciphering or anything else complicated.

View 2 Replies View RelatedI'm running ASSP on Ubuntu 10.04.1 it's mostly working fine. I have one problem which has been bugging me for some time. I don't want to filter outbound mail, but if I can relay (proxy) my outbound mail through ASSP, then it can automatically add to the whitelist.
As ASSP is a proxy, I need a server to send it to once ASSP receives it. I've tried my ISP, but this failed and they weren't willing to confirm if a connection attempt was received at their end.
Current setup
Inbound
mx -> router -> ASSP -> Exchange 2003
Outbound
Exchange 2003 -> mx
I'd like to setup outbound as either
Exchange 2003 -> ASSP -> <ISP> SMTP relay
Exchange 2003 -> ASSP -> <relay running on Ubuntu eg postfix>
Can anyone help me with troubleshooting steps or a better suggestion for how I can set this up. I'd love to know why my ISP setup didn't work, but I don't know a tool for monitoring IP traffic in Ubuntu SE, in windows I use Wireshark is there any equivalent I can setup for Ubuntu or a tool I can use in windows which will show all traffic, Ubuntu and windows server are on the same netgear switch, not sure it's smart enough to copy all traffic to another port for monitoring.
I swear Ubuntu's download pages are getting harder and harder to find things in.I help with a local LUG that holds a Clinic for Linux newbies. One of my tasks is to maintain all the latest popular distros and all the versions thereof. usually recommend Ubuntu to newcomers, but people bring all kinds of computers, many of which need Lubuntu or Xubuntu, yet others want Kubuntu, and on and on. I need all the flavors of Ubuntu.I prefer to download by torrent because it is faster with my connection. I found a page with torrents for 10.04 and 10.10 for Ubuntu desktop, alternate and server, but I'll be darned if I can find torrents for Netbook, Kubuntu, Lubuntu, Xubuntu and others.

I have just given Linux a try for the first time and so far its not proving to be a good experience. I have so far just tried to install a couple of basic programs I am familiar with and ones suggested by Lifehacker.I wanted to install Tweetdeck, which meant installing Adobe Air. I duly downloaded Adobe Air but it then says I need to choose an application to open it. Assuming that the bin file was a zip file I looked in the software centre and found 7zip. Told it to load that but then couldn't find where it was. Its not listed in the Applications drop down (top right) so I found 'search for a file' and entered *7zip* to be shown 5 files. All but one appear to be a form of image file the other (7zip.desktop) isn't an exe either. Double clicking on it just gets me the following in something called gedit.
Name=7zip
Comment=7zip compression/uncompression tool
Terminal=false
Type=Application
[code].....
I then gave up and used google to find the program and download it, but just came across the same problem. Why oh why is there not some default program already loaded for unzipping files? How can I find 7Zip (I have already looked in the bin folder on the system drive but nothing there) and run it to tell it to make itself the default for unzipping files?
I download cs 1.6 and when i click double on it it says:
Archive: /home/dzoni/Downloads/cstrike_16_1.2_v42_nonsteam_ZCP.exe.exe
[/home/dzoni/Downloads/cstrike_16_1.2_v42_nonsteam_ZCP.exe.exe]
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
zipinfo: cannot find zipfile directory in one of /home/dzoni/Downloads/cstrike_16_1.2_v42_nonsteam_ZCP.exe.exe or

View 4 Replies View RelatedVERY new to linux, erm but I have an issue that needs solving!I recently moved to university, where their network blocks sftp port 22, this means that I cannot connect to my FTP server which is running a version of linux.Now I've got this ftp server connected to a seedbox and it was created using the following walk through..Code:I have written this guide for a friend, but I though it would be useful for others as well.
There are several guides floating around, but I found that most always cock up in some way. This one is tried and tested to work on Debian Etch (on an OVH rps, but should apply to most servers).If there is a new stable release of rtorrent/libtorrent then I will update this guide to show you how to update it (without reinstalling the whole server).
At the bottom there are also instructions to install ftp access & some network monitoring software.Basically, I would really like someone to be able to construct the commands on how to change the listen port for sftp connection on linux or add another port to the list that Linux would use so that I could put in through putty.
In SuSE firewall0. I do have a openSuse 11.4 and multiple IP addresses on eth0 interface
I run (trying to/have to) multiple TOMCAT servers.
I am trying to have each tomcat instance listen to on separate IP address for example:
What i am trying to do is to redirect
a) tomcat 1 -
a) tomcat 2 -
And so on.
I know that it has to be possible.
I do have just eth0/
Is is it possible. Do I have to create "vittual interfaces"? eth0:1, .......... and do redirection ?
"Server" has got just single interface - just 1 ethernet calbe goes to that server. I am planning to have 10-15 tomcat's on that server (I have to unfortunatley) and each has to run on port 80
Is it possible to "grant" permissions to normal users to run app on port 80 - that would solve me lots of problems if impossible to redirect.
I tried to setcap 'cap_net_bind_service=+ep' /path/to/tomcat ...... but no luck
I am currently stationed overseas in Japan, and I am happy to say that I have a 100 Mbit fiber line from my service provider... 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.
Is there a program that monitors and displays 'who' is on your wireless Internet signal that one may not be aware of? Like, the ability to see when someone that you don't know is accessing your locked wireless?
View 9 Replies View RelatedI 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?
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?
View 3 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?

View 2 Replies View RelatedI 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.
View 6 Replies View RelatedI 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 5 Replies View RelatedI 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.
