We're considering moving from our current vps host with a California datacenter to a host with their datacenter in Chicago for support reasons... this will mean going from 15 ms ping times to around 75 ms. All of our clients will be running their own wordpress installations...and most of them are on the west coast as well... is the ping time difference significant or not?

I got report from webceo that I have some issues. May someone help me fix this?
DNS Lookup: 0.22 sec
Connect time: 0.33 sec
Host ping: 0.10 sec
That mean too slow with the other sites!
When I talked with my friends who are into computer stuff, they'd say that it is important that the provider that I am about to host my site with, has good ping response so that my site will load faster.

But i have been ping several major hosting USA company (like, mediatemple, theplanet, etc...) and i still didnīt get a Ping under 130ms.
If i ping a good EU company i get 60 to 90ms.
I know that the distance is bigger but,
Does anyone knows any good USA hosting company with a Ping to Europe lower than 100ms?
My budjet goes up to 800 $/moth
15ms ping vs 40ms ping vs 170ms ping
Which you think is still acceptable for a website?
From the ModSecurity manual:
Quote:
By default ModSecurity relies on the regular expression library built into Apache for pattern matching.
This works well with Apache 2.x but not so much with Apache 1.x. The Apache 1.x regular expression
engine is several times slower. Since 1.9.2 it is possible to compile ModSecurity for Apache 1.x against
an external regular expression library (PCRE, [url] the same library used in Apache 2.x)
and achieve significant performance increase. This is achieved with the USE_PCRE compile-time flag.
If you have PCRE already installed on your system it may be sufficient to compile ModSecurity like this:
Code:
# <apache1-home>/bin/apxs -DUSE_PCRE -cia mod_security.c
Ok, so I tried and got this error:
Code:
[root@servidor1 customapache]# apxs -DUSE_PCRE -cia mod_security.c
gcc -DLINUX=22 -DHAVE_SET_DUMPABLE -I/usr/include/gdbm -DMOD_SSL=208128 -DUSE_HSREGEX -DEAPI -fpic -DSHARED_MODULE -I/usr/include/apache -DUS

mod_security.c:940: error: `PCRE_ERROR_NOMATCH' undeclared (first use in this function)
apxs:Break: Command failed with rc=1
I double checked if I have PCRE installed:
Code:
[root@servidor1 customapache]# yum search pcre
pcre.i386 4.5-3.2.RHEL4 installed
Matched from:
pcre
Perl-compatible regular expression library.
PCRE has its own native API, but a set of "wrapper" functions that are based on
the POSIX API are also supplied in the library libpcreposix. Note that this
just provides a POSIX calling interface to PCRE: the regular expressions
themselves still follow Perl syntax and semantics. The header file
for the POSIX-style functions is called pcreposix.h.
[url]
And I even located the /lib/libpcre.so.0.0.1 and copied it to /usr/lib/apache/libpcre.so, with no sucess. Got the same error.
Has anyone sucessfully compiled mod_security with PCRE and can help me?

This is a rare issue i have on a RHEL 5.2 + cPanel server.
Server time is:
Tue Nov 11 17:02:51 CST 2008
Squirrelmail time show:
Code:
Last Refresh:
Tue, 5:02 pm
So, that is correct too..
But email arrives with -4 hours time, example:
webmaster@xxx.com 1:03 pm testing email
I already rebooted httpd, exim, and imap server, and the server itself too.. and problem stills.
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?
I have a dedicated server specs: AMD 3500+ 64 Bit CPU, 1 GB Ram, 160 GB Sata Drive. For 1 month, CPU load average reaches 40-50 value. This happens about 5-6 times in a day. When I stop httpd service for 30 seconds everything goes normal. I think this is not a DoS attack because it comes systematic, I dont believe no one makes this regularly except bots.
Maybe its a system service or a cronjob but it stops when I turn off httpd service?
How can I be sure about what's making this regularly load?
I also did set up a script which mail me when load average of system goes crazy and restart httpd service. But instant restart is not working to stop load increase.
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 just moved from PowerVPS to EuroVPS, being located in Europe myself, and was of course hoping for much better ping times. Also EuroVPS advertise themselves with a 30ms ping to most of Europe.
Anyway after my VPS was installed I compared the pings:EuroVPS (85.17.48.162) average ping: 335ms
PowerVPS (69.65.106.19) average ping: 129ms
335ms is of course ridiculously high, and after writing them a support ticket they told me it's probably a latency problem with my ISP
Can you please post the ping you get for 85.17.48.162 (preferably people located in Europe)?
I have configured Nagios on my network 10+ Servers (Linux+Windows) now when i check through http://localhost/nagios everything is ok but only ping command is giving following message :-
Unknown
bin/ping -n -U -w 10 -c 5 x.x.x.x
CRITICAL - Could not interpret output from ping command
and mail me "server down " message
So what is the issue ?
I am able to run this command through command line
./check_ping -H {server} -w 100.0,20% -c 500,50% -p 5
PING OK - Packet loss = 0%
./check_ping -H x.x.x.x -w 300.0,80% -c 500.0,100% -p 5
PING OK - Packet loss = 0%
I'm running my own OpenVZ server with a few VPS's running on it and have a small network issue.
I can't ping any VE from the HN. All the other networking is working ok (strangely I can ping the HN from the VE) apart from this. It's a simple setup with one network card connected to the internet.
OpenVZ the latest stable version running on CentOS 5.2
I'm pretty sure it's not a firewall problem but is something to do with arp or routing and one of the settings in sysctl.conf
Has anyone else seen this?
Does it matter?

My sites are up when I go to http and there is no slowdown but my monitors (panopta and pingdom) say that there is an outage in ping (only in ping, http is up). I tried pinging the server and there are packet loss up to 100% but the site is still up. I also used other online pinging tools (all-nettools.com, dnsstuff.com, etc.) and host unreachable.
I tried contacting the provider but they say there are no network problem at this time. So I found this other site that's also hosted on the same provider and I can access their site but fails on ping.
My server ping keeps disconnecting
However my ssh & website is smooth running!
When i type "service iptables stop", the ping runs just smoothly.
I have CSF installed in the server, like any other server using default configurations. I believe it has something to do with selinux? (or not?)
i think 216.245.208.x and 216.245.215.x DOWN, but limestonenetworks tell me :"problems well outside of our network, and I would highly suggest contacting your ISP for support on this matter" ....

If I enable ping requests people can visit my site/server.

But i can log in the ssh. i just installed apf, i check conf.apf to made sure there are port 80, but it still can't ping.
So I'm wondering what if anything I can do to get a better ping from my 1and1 server.
It's located in Wayne, PA and my ping floats around 70ms and I'm in South Lake Tahoe, CA. I only ask because there are servers with Peer1 hosted in New York, NY that give me a ping around 20ms.
Thanks for any help or advice.

They say in order for ping and trace to work, you must chmod those executables on the server itself to 755. Is this safe or a security risk? The odd thing is, ping and trace works fine from dnsstuff.com or any other network tool site.
What is the location of those executables?
I have two servers both in a same vlan. Both may access Internet and be acceessed from Internet I setup db server and web server internal IP each as follows:
step 1: on web server:
vi /etc/sysconfig/network-scripts/ifcfg-eth0:0
add following:
DEVICE=eth0:0
BOOTPROTO=static
BROADCAST=192.168.1.255
IPADDR=192.168.1.5

save and /etc/init.d/network restart
step 2: on db server:
vi /etc/sysconfig/network-scripts/ifcfg-eth0:0
add following:

I used ifconfig to check both status, both of them are up. both of them may ping google, but when I try to ping their each other through internal IP, nothing returns.
I used command tracert to follow, found all packages were sent to Internet rather than an internal IP.
My host tells me to do it by making NAT, I have no idea on it. Anyone may help me out on how to do with NAT?
