Monitor/track Bandwidth With Ipchains?
Sep 28, 2006
I'm working on setting something up for monitoring my bandwidth/traffic on multiple interfaces. I have setup interface aliases so I have eth0, eth0:0, eth0:1 and the issue I'm running into is that it seems snmp cannot tell the diff between the aliased interfaces. I've found references in the cacti forums of using ipchains rules to track the bandwidth, but I've not found a good howto that explains what I need to get going on this.
Any clues/hints?

I have a windows vps and I want to monitor my bandwidth. How can I do this? I tried using a program called DU Meter but it's counting bandwidth on all users on that node and not mine =[

I know cacti / MRTG can produce traffic graphs, but how you actually get Cacti to graph the VM's on a physical server?

I will be setting up a LAN at home where there will be a few PCs connected to the network.
My idea is that I will have linux box where I will route all the traffic through to monitor it. I was wondering what would be a free solution to go "hardcore" on this. When I mean hardcore, I really mean hardcore. I want stats, packet shaper etc.. It would be a learning process for me too. The only thing is that alot of solutions out there are more enterprise and expensive.
Anyone here use or know a good solution? I was told I could use m0nowall on freeBSD. Another thing I was looking at would be Squid. But to be honest I'm not sure.
Whats a good free software that can do this? Perhaps something really cheap if there is a cost involved.

Does anyone have a tutorial or instructions to show how to set up munin to monitor bandwidth/traffic utilization?
I have a VPS from a provider that has no monitoring tools, and I need something to monitor.
(The VPS uses the HyperVM software.)
I am using the CentOS version 4.x right now, and munin is already set up and configured with a basic install.
Anyone know how to add traffic/bandwidth monitoring? (Ideally, it would monitor all active ports.. but I only really need it to monitor port 1194 for openVPN software.)

if anyone knows of a good, free tool to monitor how much bandwidth a Windows machine uses monthly. I saw FreeMeter, but I don't know how well that will work to use for a whole month at once.

My server currently has some problems with DNS/mail, which i can't seem to fix myself. My colocation host offered to help me by giving him root access, but i don't know him very well yet. Is there some kind of script/logtool so i can track everything he did on the server? I don't want him snooping around through my webfiles and databases...

Can anyone please tell me how dangerous in fact Apache's TRACE and TRACK functions?
I have read common explanation but would disabling TRACK and TRACE improve my server's ability to fight cross site scripting and similar attacks and make it more secure?

I'm small hosting provider. On one dedicated server I have around 100 cPanel accounts.
That server is under constant, although not powerful DoS attack.
Since my company domain is not targeted on another server I believe that it is not me but one of my customers that attack is against.
Is there a way, tool, service provider than can help me pin down which account is being hit?
All accounts are on server main shared IP.
Would spreading them on another IPs help? Or would I still see attacks only on main shared IP?

I have a few shred hosting servers I run. One of them keeps getting listed on CBL. It is very frustrating. Does anyone have an tools, tips, or tricks on finding the compromised?
So far I have confirmed that a script is using PHP to send mail out bypassing the MTA. It is faking the HELO and impersonating a well known ISP.
I used a combination of tshark and netstat. tshark can show me the HELO and EHLO. When I see the wrong entry I cross check that with netstat to see what. So Netstat only shows that it was PHP not the script path.
Here are the commands I'm running:
Code:
nohup netstat -c -p -n -e | grep -i ":25" > /var/log/monitor/netstat-smtp.log &
nohup tshark -f "port 25 and src host XX.XX.XX.XX" > /var/log/monitor/tshark-smtp.log &
Then I grep for what I'm looking for:
grep -i "HELO" /var/log/monitor/tshark-smtp.log
Is there a way to get Netstat to show the script path or complete command that is establishing the connection? Currently these scripts are eating up memory to a point that other process or getting killed off.
I also tried to force all mail through the MTA, but When I enable SMTP_BLOCK in my firewall config I get and error:
*WARNING* Cannot use SMTP_BLOCK on this VPS as the Monolithic kernel does not support the iptables module ipt_owner - SMTP_BLOCK disabled.
If there is a better way I'm game. Maybe some IDS that can tell me more of what is going on with the server?

I am currently developing a web application on a WAMP server. Once complete my client will have some in-house "programmers" make changes to the code as they are needed.
My client wants to track all changes made to the source files (ie- who made the change, when it was made, what files were modified, and what specific lines were added/removed/modified). Also, the program must run on the server and not the programmers computers.
I've searched high and low and only found a couple programs that scratch the surface of what they want.

how exactly email works. For example, I set my mx record to google apps in order to use google mail with my own domain. Thing is, I can sent from google mail now with my domain email address but cannot send. Furthermore, login to my website email bij www.domain.com/webmail is possible but receiving is impossible and even sending email from that place will not work.
Thinking about it it seems that email is lost
google can send but not receive
from my domain webmail i cannot receive nor send.

I've done plenty of searching on DDoS attacks and from what I've found so far it seems that it's "very difficult" track down the person(s) responsible for the attack.
My question is this - could someone actually do it if they were qualified enough? Would a hacker who is well versed in the techniques used be able to find the person(s)? Or is it just simply impossible sometimes?

I just installed Apache 2.4.4 and it seems to run fine overall. But in my error.log I get about 3 of these every hour or so.error.log:[Sat Jun 15 20:57:44.095961 2013] [core:notice] [pid 31400:tid 16384] AH00052: child pid 1971 exit signal Segmentation fault (11)
track down what causes this? What module? vhost?Otherwise the server seems to run fine. It's on Linux with PHP 5.3.26 and MySQL 5.1.

Logwatch says I send out about 3k emails each day and that is a ridiculous amount. I use postfix and do not run any sort of relay, even for myself. I have IPB 2.2.2, Wordpress 2.0.4, and Gallery 2.x.
How can I track down where these messages are originating from? Or perhaps I am reading my LogWatch file incorrectly?

I'm wondering if theres anything I can install on the server that will either filter or track outgoing spam. I don't want to limit the number of emails sent per hour or anything, I just want to be able to maybe search through some flagged emails or something. Or if they send the exact same email more than x times it can disable their account... I'm not sure

Often when it comes to choosing or recommending a host, I tend to favor the ones that are larger, and more established such as Hotgator or Downtown Host. But in some other threads, I have seen plenty of people swear by some smaller hosts. Are there some good examples of small hosts that have been around for 3 or more years and have a great reputation?

I've been trying to use mod_forensics – [url]-- which has helped on one server track down some one causing the segmentation fault due to trying to abuse FrontPage shtml.dll, but on another server also suffering from regular segmentation faults, this tool has not helped.
What other tools are available to track down the cause(s) of Apache segmentation faults?

I know it's not specifically a plesk issue, but as I use plesk to resell webs and many users install (manually) wordpress, I thought I'll ask around.I would like to know if this can be done with a single sql select or if I would have to use a script to do this:
- track all mysql databases on my server
- find the proper table in each database (as the prefix can be customized, the start of the table name will probably never be the same in two WP installations)
- find the proper field in that table and check the WP version and administrator email
and then what I will do is send an email to those adresses advising them to update WP

I have a Sonicwall NSA 3500. Does anyone know if you can use it to create bandwidth charts of Network Objects (e.g. IPs or Groups of IPs)?
I am thinking something like Cacti, but I don't know the code to pull that info or if it's even technically possible.
