I want to test an new Application Server by duplicating the traffic from the old production system. Answers of the new will be DROPped ...
I am using CentOS 5.4 and did a yum install of cacti. I installed all the necessay packages, like net-snmp, php net snmp and all that. Everything else works but I can't for the life figure out how to monitor traffic on eth0. I do not have any SNMP Interface Statistics or alike in either the Associated Graph Templates or Associated Data Queries.
Heres the output of "snmpwalk localhost -c public -v2c" , SNMPv2-MIB::sysDescr.0 = STRING: Linux xxx.xxxx.net 2.6.18-164.6.1.el5xen #1 SMP Tue Nov 3 17:53:47 EST 2009 i686

Which is best server monitoring (Traffic ) tool ?
Can you provide some form of monitoring on this server or recommend any server-side applications that could monitor the status, in high detail, including traffic, etc?
I'm looking for a monitoring tool like ntop, but can preserve statistics for http traffic.

View 1 Replies View RelatedI have searched and searched for a reverse proxy solution for non-website traffic. TCP but not http, on ports other than 80, 443, 8080, etc. Basically I just need a TCP forwarder that works with multiple TCP servers, WITHOUT webpage caching features. I do not need or want any webpage caching. Can squid work as a reverse proxy for TCP traffic without http? The other program I came across in searching was HAproxy. Both programs are for http but I am curious if they would work for TCP servers that do not serve webpages.

I then proceeded to setup an configure the Proxy Server, i was able to test and confirm that Squid and Dansguardian Content Filter is working, however i dont know if Clamav is scanning HTTP traffic before it hits the client/server. Is there a way i can check if the Antivirus scanning is working.. is there some log file or real world test i can i can do to confirm that Clamav is scanning incoming traffic or even blocking potential viruses ??
Anyone who has squid proxy server with Clamav configured and its working can share there settings/setup with me and how they tested it ??
Recently I notice that when I'm connected to an vpn server (pptpd) and I'm using it as a default gateway my download and upload speed decreases almost to the half of the usual speed. I made a test using iptables in order to count how much GRE packets are generated (except the real traffic itself) in that way:
Code:
iptables -I INPUT -p gre -j ACCEPT
iptables -I OUTPUT -p gre -j ACCEPT
iptables -I FORWARD -s 172.16.10.101 -j ACCEPT
iptables -I FORWARD -d 172.16.10.101 -j ACCEPT
The first 2 rules match all GRE packets between the pptpd server and client, and the next rules - the traffic between the server and the client.
When I turn the counters to zero and begin to generate traffic (to browse, to download etc.) I see that the GRE packets are even more than these in the FORWARD chain.
So, my question is first of all is my test correct and is it true that so much gre traffic is being generated during the browsing (it becames clear that the traffic is double than if the pptpd wasn't used as a gateway) and if yes - can that traffic be reduced?
I have a UBUNTU server 10.04 LTS with 3 network interfaces (eth0,1,2) with eth0 is connected to my lan and others connected to two different ISPs , I am looking for a very flexible and complete monitoring tool which can monitor all of the traffic of incoming and outgoing of any interface and SPECIALLY can show me which local client made connection to which interface for connecting to internet in online mode not offline and it is good to have online web base interface I mean the interface shows the measured data in real time mode. I fount some tools like iftop and iptraf and many others in this url: http://www.ubuntugeek.com/bandwidth-...for-linux.html but non of them are suitable for my net I mean none of them have good web real time data and non of them shows "which local client made connection to which interface for connecting to internet".

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.

View 3 Replies View RelatedI've read up some of the posts on this forum, but can't seem to find an answer. I have a web service within an Apache Tomcat instance installed on a Redhat linux server. I only have shell access to the server, and need to monitor outbound network traffic from my web service. Is there a unix command that will allow me to monitor all outbound traffic? I'm thinking fiddler, but a unix version? I've heard of things like ntop and iptraf, but I don't think those will help me in this instance.

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.

Is it possible to have both Windows XP and Linux web server in one computer?
I wanted to tell my server to block all traffic but US only traffic. So i followed this guide:[URL].. Now I know, it's the best way to help prevent hackers/crackers (doesn't matter to me what they are called. I just have to stop them). My server only deals with US clients anyways so might as well just start right there for my server's security before getting into the brute force and injection preventions. So I got it all done compiled everything moved to the proper directory. I then started to setup my iptables. Like so
Code: iptables -F INPUT
iptables -F OUTPUT
iptables -I INPUT 1 -s *.*.*.* -p tcp --dport 22 -j ACCEPT
iptables -I INPUT 2 -s *.*.*.* -p tcp -j ACCEPT
