For some reason, one of the servers can't connect to my mail server. Whenever a user tries to send email from that server to my server, the message won't go through and I see the following in the logs (var/log/exim/mainlog):
2007-02-13 23:56:06 SMTP connection from (***.ca) [***.***.***.***] lost while reading message data (header)
this problem occurs only with this ***.ca mail server (as far as I know).
In fact, trying dnsreport.com tool on any of my server domains, I am getting the error message
"ERROR: I could not complete a connection to any of your mailservers!
******.com: Timed out [Last data sent: RCPT TO: ]
If this is a timeout problem, note that the DNS report only waits about 40 seconds for responses, so your mail *may* work fine in this case but you will need to use testing tools specifically designed for such situations to be certain.
We have many webservers in our environment, Few webservers serves static contents. In one application, we often change the excel file. Every day or 2 days once we will modified the excel sheet content. File name will be the same, only the content will be changed. We will modify the content of the sheet and upload through FTP to the docroot. After we done this if we access the application URL, its displaying the old content. Its takes time to reflect. sometime with in 3 hours sometimes after a day only reflecting. We are not sure what is the issue. we cleared the cache in browser and tried then also its showing the old content. We are using DNS,network load balancer, proxy between the browser and the webserver.
I tired accessing through FQDN, it showed old content, then i accessed through the LB IP it showed the modifed file. For testing i changed the content again and then accessed. This time even for IP it showed old content. Same i tried with the instance 1 IP and Instance 2 IP. On first time it showing properly but after i cahnged the file content and accessed it showing the old file I tried accesing from a different PC where we havent accessed before, there also it showed old content, SO i feel browser cache is not an issue.
We using Source subnet mask IP persistence in load balancer. I am not sure where the old file is cached actually. Will it be cached in Load balancer or proxy or somewhere in webserver. Just we are placing the file in docroot and accessing it in the URL

Is there any way to disallow connections to SEND mail FROM my server to specific IPs? (Similarly to how you can limit connections to sshd from certain IPs)
I realize I cannot disable everything completely, as yahoo and the likes will have to connect to deliver mail. But no one of any use is going to try and connect to send mail, but a spammer.
No one has gotten in and abused it as of yet (knock on wood), but SMTP is being restarted at random and I can only imagine that this is being caused by one of these scumbags probably ddos'ing me. It takes eons to browse these logs, even if they restart via logrotate periodically!
My server has been crashing quite alot lately, it does have some high traffic sites on there but it has never really been this bad before. Today i noticed these in cpanel, what are they and is there anyway I can control them?
I was on a 100mbps shared port with a dedicated server from FDC and I use it only for downloads. The downloads took a little long to start but once they did, were as fast as they could be.
Thinking this was definitely a shared bandwidth problem, I ordered a dedicated port of 25mbps from FDC to fix it but it seems to have gotten worse.
The website uses around 10/15mbps but it takes forever for the server to respond. Even logging into cPanel takes around 40/50 seconds for the dialog box to appear but everything is fast once I log into my cPanel.
I also hired a sys admin to look into the server and He says everything is fine. I don't know what to do. I could increase my port bandwidth higher but it'll be disappointing if I do and it's just a waste of bandwidth (and money!)
suddendly some of my sites in my server is taking sessions errors...then after a while all its going ok and then again the same problem...the problem still continues.from what might be the problem?a php update?mysql update?any exprerience?
i havent made any change.my server is linux has centos 4.7
Warning: fsockopen() [function.fsockopen]: unable to connect to mail.userdomain.com:25 (Connection timed out) in /home/user/public_html/_inc/class.smtp5.php on line 122 Message could not be sent. Mailer Error: Language string failed to load: connect_host
I can't get access to a certain site. I always get the page with:
network time out - server at *** takes to long to respons. More people have noticed this and apparently it only happens to people with certain specific providers. And not all the time. Some times they DO get access eventy to they belong to the same ISP. So I guess an ISP isn't blocking access to it otherwise it would be permenantly/The site administrator insists that certain ISP's are blocking his site. He's hosting it on his own server. The domain belongs is registered at namecheap.com.
If an ISP is blocking this site (if that's possible?), that would lead to that 'network timeout' page wouldn't it?
What is the most likely reason for getting a timeout page anyway?
The server is going down from time to time, every 12 days or so the site hosted there is no longer accesible, everything starts with the site slowing don and down and then is not longer reachable, what we do is to request a power cycle, and with this we start all over again till next power cycle, so on so on, of course, here are my server details and more info on this:
- MySQL - 5.1.41-3ubuntu12.10 - Apache - 2.2.14-5ubuntu8.4 - PHP - 5.3.2-1ubuntu4.9 - operating system: Ubuntu Server 10.04 LTS
After some time emailing the support guys to barely check about what's going on, we received an email with a few things:
1.- found a few errors that likely would cause issues with Apache. The first error is: [Mon Feb 04 05:03:10 2013] [error] mod_fcgid: fcgid process manager died, restarting the server and the next error is: [Mon Feb 04 14:32:34 2013] [error] server reached MaxClients setting, consider raising the MaxClients setting ...
Both these errors seem to indicate that you have a process that is running out of control on your server. We were unable to determine what script on your site is running caused your connections to be maxed out however it does appear that before these errors were generated there was a WordPress plugin referenced in your access logs...
2.- Additionally during our review we did find that your error log for mercadodedinerousa.com is 45 GB's which is excessively large and can cause problems when Apache is trying to write a such a large file.
3.- The majority of the errors being logged are: [Wed Feb 06 12:12:31 2013] [error] [client 200.76.90.5] Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden: /var/www/vhosts/mercadodedinerousa.com/httpdocs/index.pl, referer: [URL]
I run a website that uses a GoDaddy Virtual Private Server & Plesk. The website sends emails to alert users of various events. For the most part, this works but I occasionally capture the following error message:
Error in processing. The server response was: Requested action aborted: This mail account has sent too many messages in a short amount of time. Please try later.
Can the number of messages sent over X number of minutes be set via Plesk? If so, how?
