i want to ask any any setting or script can help medo the purpose?
i hope i can set a cron to trace server load every five minutes,
and help me record the load number on a log file,
by the way,
i can trace the past load of my server when i need the data.
I have a shared server (root access) using Cpanel / Centos with suphp enabled.
Twice this week the sever's load skyrocketed and was unable to login to trace teh cause, had to reboot instead.
After reboot, I went to whm > CPU/Memory/MySQL Usage and saw nothing in red aside netstat (21% cpu). I'm not sure if this is the cause, but how can I trace the absolute user or script causing this spike?
This is a RHEL3 box. It has a couple hundred sites, most of which are pretty quiet most of the time, lately I can't get the load below 3 most of the time. I've tried all the usual TOP PS and the rest, but I'm not seeing my problem. I've attached a text file with extended outputs. but here's what I'm seeing now from TOP and VMSTAT. I'm not sure what else I could be looking at.
I've been watching, and it seems to be Apache most of the time at the top of TOP, and I'm logging slow-queries for myslq, but there aren't many there.
top

I have been trying to identify why mi server has high load cpu, suddenly CPU load suddenly jumps, from 1 to 40 and until 110
If I restart mysqld and apache, the cpu gets back to normal, until this happen again
My server is
GenuineIntel, Intel(R)Core(TM) i5-2400 CPU @ 3.10GHz
VersionParallels Plesk Panel v11.0.9_build110120608.16 os_CentOS 6
CentOS 6.4 (Final)
CentOS 6 x64 Processor: Intel Core i5 - 3.10 GH
I already installed FAIL2BAN and DDOS DEFLATE without lock. I have CloudFlare Enabled.
When there is a high CPU load, I have checked netstats, and I don't identify many ips connected, so I think it could be an internet script (or virus).
I will paste the result of
ps fax
command, in a moment of high cpu load
Anyone have any info on how to do this? It appears my hosts don't know how to do it..
"You have the tun module which can be loaded via a modprobe but the dev entries would appear to be needed to be made. Of course, you could do this if you know how or wait while I research it. We know tun/tap works on openvz but you're the first request we've had on Xen."

Hi over the last week ive been having numerous problems with hosting accounts on 2 different servers which has lead me to think that my 'security' is not 'secure' and a malicious user is at play. im in the uk on broadband on a private connection to the internet - no-one else should be sharing this connection. This is the traceroute from my connection at home to the server ive had the most problems with - is this normal?

Which file do I need to open on a Unix server to add a PTR record? Sorry, I'm clueless about DNS but I think if I could find the file, I can add the PTR record by piecing together what I've found through searching the Internet.

View 0 Replies View RelatedI am currently having a few technical difficulties with configuring my PLESK server to accept an A Record from another domain. Perhaps I have been going about this all wrong but I will explain what I am trying to do and how I have currently been trying to get it to work. Hopefully you might have a suggestion for me to try.
We currently run an On-Demand web design platform. This CMS can be completely rebranded for our Partners who can then sell this facility to their clients. There is only one installation of the code base but we need to give our partners a their own web address to access the cms.
For example:
cms.altstudio.com.au
cms.pcgraphicart.com.au
cms.pcgraphicart.com.au has been set up as a domain alias. The reason this is working is because the primary domain pcgraphicart.com.au is also hosted on this server.
So I thought if the partner has their domain delegated elsewhere then I could simply get them to create an A record for their chosen subdomain and point it to our IP address, then I could configure the domain alias again for their particular A record and hey presto. Unfortunately not so easy.
Here are two of the examples of what is happening
cms.newlight.com.au - their root domain is delegated elsewhere, but they have created an A-record for that subdomain and pointed it to 202.60.87.185. Now it reaches my server as I see a PLESK error page at that address.
At this stage I don't really know what to try to get PLESK to register that entry. I have created a domain alias for cms.newlight.com.au on the cms.altstudio.com.au account but it didn't pick things up.
Another example is cms.abconsulting.com.au
we have 2 server
on the first server we have setting 2 account
myaccont.com
and
my1.myaccount.com
are 2 difference account
Now, on the second server, we must config account
my2.myaccount.com
--
On the second server we have config my2.myaccount.com as account On the first server we have modify dns of domain myaccount.com with
my2.myaccount.com 14400 IN A xx.xx.xxx.xx
where xx is ip of second server
--
Seems work but there is any problem
For example ping to www.my2.myaccount.com give error, ping to my2.myaccount.com is ok..
Why?
I run an online music archive site . Djs can upload their mixes to share and we also archive radio shows for people to listen back to.
Basically I was wondering if it would be possible to build a secondary server that could do this for me.
The secondary server could have multiple cast rippers running and could record internet radio shows, then once finished recording transfer it could send them over to my primary server to add to the website for people to download.
I was using dedicated server from ev1servers.net.
They are excellent. One of the feature .. unless I forgot was the ability to add our domain record to their DNS server by ourselves.
I think it was controlcommand, or commandcenter, or was it controlcentre , I forget.
This feature is very fascinating as I can make my site up and running within second.
[I know where to register domain with real time activation, and I have reseller account with WHM]
So everytime I have an idea of making a website. All of this cycle can be done within seconds , and my site is up and running. [register domain, create account in WHM, and populate the DNS record]
Anybody know any dedicated server provider which offering this kinda feature this day?
I have a dedicated server that is running apache and exim. While they're running from the same IP, I want the domain names to be www.mydomain.com for http and mail.mydomain.com for SMTP.
What I've done so far is set up A records for *.mydomain.com and mail.mydomain.com to point to the same IP address.
My MX record points to mail.mydomain.com.
My exim primary_hostname is configured as mail.mydomain.com.
Now I'm trying to get the PTR record set correctly so that outbound email doesnt get trapped by spam filters. So in this case should my PTR record point my IP to mail.mydomain.com and not mydomain.com or does it not matter?
Is it strange that an RDNS lookup to the primary IP would return my mail server like that?
somehow plesk is not listing a domain record I added recently, that I have to remove. so, I can't select it and delete it through the interface.
is there a way to remove a dns record manually, perhaps from the command line?
when I run DNS report for some of domain of my it give few errors on
1)
SOA MNAME Check Your SOA (Start of Authority) record states that your
master(primary) server is: Fail
2)
Invalid characters Checks if MX records use valid host names, without any invalid characters. FAIL
how to fix this using WHM.
I have one domain who's not create dns in MS DNS server, i try create manuall but after this the record is missing, but on plesk showing, How to fix this ?
View 2 Replies View RelatedScenario: I have a website, www.site.com, hosted on an ensim 4 box. The MX records for that zone point to google apps for mail services. Some of the alerting tools my client use are too stupid and don't support SSL or TLS, so they don't work with the pop/smtp services google apps uses.
Can I setup this ensim box to utilize it's smtp server to send mail as user@site.com even though the mail is hosted by google apps?
I guess it's kinda like e-mail spoofing.
I'm having the oddest issue. For some reason, some of the websites on my server load fine, and some take a really long time to load (2 minutes).
Now, the server load is fine, and the size of the sites aren't the issue either. I've restarted Apache and a couple more services, and still the same sites seem to load very slow.
What could be causing this since it's only effecting certain websites?
I don't know whether possible or not if we can trace the dns from certain reseller webhosting and found where she or he bought the package... maybe it is important because we must know the reputation of the seller.
