I designed one of my web services so that 'nobody' has to put commands to cron. Unfortunately this thing stops to work from time to time because "someone" is putting 'nobody' back to cron.deny file.
How to stop that?
I edited the /etc/apf/deny.hosts_rules files, then removed all lines from the file and finally restarted apf so it can restart with no deny host listed. But that is not working... the file appears empty or again with the rules removed before.
iptables -L -n shows the same banned hosts as dropped.
I already tried.. remove the deny hosts IPs from the file, then ran "iptables -F", then "service iptables save", and finally restarted apf and the deny IPs still there

Currently my site is having a extreme surge in traffic (in and out). My webhost just sent me a warning, saying that my site is generating abusive traffic to the host's network.
Code:
Please be aware that abusive traffic is being generated from your IP, xx.xxx.xx.xxx, directed to our network as seen in the logs below. We have added a Nullroute for this IP on our network for a period up to 24-hours. Please take action to remove and prevent this abusive traffic from being generated. Repeated offenses will result in a permanent Nullroute of your entire network block.

My VPS is using Plesk v8.01 as the control panel. I have purchased my own 3 IPs so I'm sure this is not the case of sharing the same IP with another account.
I've checked the cgi-bin directory but there is nothing there except the usual default file (test.cgi). And I never have the right to alter the cgi-bin directory (can't remove, can't add files).
The traffic surge costs me 10 GB (in) and 5 GB (out) bandwidth a day as opposed to the normal 100~200 MB a day. I haven't ask them the exact form of the abuse. So far, I think my IP has becoming the source of abusive traffic that burdens THEIR server.
I've checked the latest access.log and everything looks normal.
But when I checked using menu Virtuozzo/Traffic Statistics, I can see that the incoming and outgoing traffic are surging up unnaturally (this is the third day).
Hour/Incoming/Outgoing (in MB):
Code:
01 5.61 26.31
02 4.94 25.11
03 6.77 33.48
04 10.42 47.17
05 91.43 94.06
06 289.51 196.99
07 309.13 200.02
08 51.78 33.33
Has anyone had any good results using spamassasin? If so, how did you go about setting it up? I was hoping someone would share some real world settings that work.

I have CSF on my server (configserver security and firewall) and it blocks the IP when my server gets attacked, but it always seems to be a little too late... Apache goes down, even though the IP is blocked. I end up running:
iptables -I INPUT -s xx.xx.xx.xx -j DROP
service httpd restart
And that tends to sort things out... but the thing is, sometimes they still manage to attack and even though csf sends me messages explaining how it is connecting, I can check the "deny IPs" and the ip shows as blocked...
What other software is there (eg. mod_evasive... but how can I install it...) that I can run without harming my server, causing problems with CSF or any problems for that matter and how can I install it?
Apache keeps stopping. MULTIPLE times per day! There is no logic to when it dies. But about every 2 hours.

Is there a script or program which I can use to start my game servers remotely? I am giving my friend a free game server, but the problem is that he wants the power to start/stop the server because he wants to update the binaries. I am not looking for a game server control panel, but more like a small script or program that has the power to start/stop the server. The game server I am hosting for him is Team Fortress 2. Also, it has to be free since I am not going to make any profit of this.
Game - Team Fortress 2
OS - Windows 2003 Server

I will move my vbulletin site from one server to another server.
my web data is more than 10G including mysql data, I know I may stop the vbulletin at first and move data. but I am expecting a minimal forum-stop time or no forum-stop time.
My concern is, if I don't stop the vbulletin at first, after I dump sql data out and retore them to the new server, it would be more than 3-4 hours, there must be some new data come in during that period. how may I keep the vbulletin running and move all data to new server?
We're currently testing Postini after checking with Message Labs, etc and it seemed that Postini was the most highly recommended out of all of them. We shall see, as there does seem to be ALOT that get past their filters with spam level filtering set at their most sensative level.
However, what could I do for accounts with Hosting Firms. We have a couple on Pair, and while they use SA, their filters doesn't seem to be really effective at all. Users can come in over the weekend, and have 5 valid emails out of 200 junk......
BTW, has anyone used any of the spam appliances out there lately.
We tested them about 1.5 years back and none were really effective

We have a VPS Server from one of the most reputable VPS Provider. We have 384 Guaranteed RAM and 1GB Burst. We have Dual Core AMD Opteron(tm) Processor 265 - 1795.503 MHz with 1024 KB cached allocated to our VPS.
It is only hosting 2 average forums (10-15 concurrent users in total) and 30 small websites, low traffic websites.
The problem we are having is, almost 3 times a week, the cPanel, named and apache services keeps stopping. I am monitoring our server when this is happen and prior to the event its only using about 300MB RAM and low CPU..
What could be causing this problem? Do I need to upgrade our RAM?

View 7 Replies View RelatedOne of my client got DDOS on his website. He has visitor tracking module in his php script so he got almost 50,000 records during couple of hours. Normally he gets around 300 unique visitors per day but that DDOS added 50,000 records in tracking table. After extracting this data I got around 400 unique IPs.
Will this work if I added all these IPs in IP Deny Manager?
Will this stop DDOS from these IPs?
Will server not treat requests from these IPs as grabadge load?
Another question is from where these attackers got so many IPs? Definitely they pay to get IPs? how much they pay? Is this very easy to get so many IPS?

Completely new stuff for me so i have a few basic questions.
It all started after i've noticed a lot "/w00tw00t.at.ISC.SANS.DFind:" lines in log and after i've found they are random scanning by some hacker tool.
It is suggested to block IP's from where those attacks is comming by putting IP+s in host.deny.
Correct me what i am doing wrong as i keep seeing those scans after I've updated deny file.
I've edited hosts.deny like this:
ALL: 77.68.37.242, 89.19.2.58, 80.93.210.194
That is correct?
After that i've restarted sshd service but i still someone scanning my server from those IP's.
I have problems configuring some ports and rules on CSF on a cPanel server.
Port 37500 is used by a Java web app, so, i opened both tcp incoming and outgoing ports:
Code:
TCP_IN = "20,21,22,25,26,53,80,110,143,443,465,587,993,995,2082,2083,2086,2087,2095,2096,37500"
TCP_OUT = "20,21,22,25,26,37,43,53,80,110,113,443,587,2087,2089,2703,37500"
Then.. to allow access from the server IP and localhost, added this at csf.allow:
Code:
tcp:in:d=37500:s=127.0.0.1
tcp:in:d=37500:s=my.server.ip.address
csf.ignore:
Code:
127.0.0.1
my.server.ip.address
And to deny all access to the server on that specific port (except for the ones I whitelisted before), added this to csf.deny:
Code:
tcp:in:d=37500:s=0.0.0.0/0
Result = no one can connect to the server on that port, not even from the web app itself, it's not connecting to the port 37500.
How can I configure port 37500 to accept local connections (from the web server) and deny all external connections?
Yes, more ssh problems. I fixed it the last time. My IP was being block in "/etc/hosts.deny". So I removed my IP and BAM worked! I could login to SSH. Now today I get locked out AGAIN. I go in a look in "/etc/hosts.deny" my IP is not in there. So now I'm so confused and can't figure out whats going on....

Hello, I recently got myself into an unmanaged VPS package and I noticed in my log files, countless attempts to ssh into the system. After a bit of searching, fail2ban looked like a good way to ban the brute force attacks automatically.
My question is what should I configure it with? There's the option for iptables or host.deny. I've read that iptables are not fully supported under Virtuozzo but the stuff I've read are a bit dated. Are there still some issues with iptables under Virtuozzo?
