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...
View 13 RepliesI am having trouble finding a good sysadmin for my needs. Has anyone else been in a similar situation? Does anyone have any advice on how to find somebody like this?
SITUATION:
I am having trouble finding a reliable RH sysadmin. I have a handful of clustered HA setups for customers (6+ servers & load-balancers) and a number of single-server dedicated hosting customers. I do a lot of the work myself. The additional sysadmin usually only has a small amount of actual worked hours per month, dependent on new installs. But, they need to be reliable, available, and familiar with the complexities of the setups.
From what I have seen, some sort of server management company wouldn't be able to be familiar with the setups well enough to not regularly make errors or modify setups correctly due to the amount of clients they have.
Suddenly Apache started acting weird, I rebooted the server, Disabled suexec, and a lot more thing to make it work..
But I'm not able to figure it out.
i have problem in SSH if i want to restart it its say:
sshd has failed, please contact the sysadmin
can any one tell waht i do?
So one of the sites on our box was compromised earlier today.
We've shut it down for now and contacted our sysadmin to help research the problem. Not sure if he will be able to really help much as he's only done updates and such in the past.
Any idea of quality sysadmins who might be able to investigate the box and the site?
httpd has failed, please contact the sysadmin

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'd like to know, is there any way to know about hosting provider, if we have only ip address of the server. i.e.
66.63.181.74 - this is the ip address of my website server, how can i trace the service provider who is giving this hosting service?
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.
Is there a way I can track the HTTP traffic to which domain is running with high traffic. Due to traffic load I/O wait is increasing. I want to suspend the domain that have the large traffic to avoid down time.
View 4 Replies View RelatedI'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.
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?
What script/application can I install on my linux box to track the bandwidth per each domain?

I'd like to track the email user agents that our clients use. Basically, I'd like to have something that looks like that:

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?
Quote:
--------------------- postfix Begin ------------------------
17999281 bytes transferred
2460 messages sent
26 messages expired and returned to sender
145 messages removed from queue
Top ten senders:
24 messages sent by:
apache (uid=48):
2 messages sent by:
root (uid=0):
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
View 1 Replies View RelatedOften 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?
View 12 Replies View RelatedI'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.

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
