Cross-connects And BGP
Jun 27, 2008
I have a facility that offers racks and bandwidth (expensive), however the same facility is a POP for Cogent as well, who after I contacted informed me that I can buy bandwidth from them directly and just have the racks with said facility.
Now, besides my servers, do I need to own anything in order for me to mix my 100MB uplink from my Rack provider and Cogent?
I am assuming that with Cogentco I will be able to get IPs more easily and thru them, so if I renew my contract I don't have to migrate class C no matter what datacenter I host (as long as I have cogent in the mix, correct?)
BTW; is it usual to get charged anything for BGP or cross-connect, what do you pay?

I had an VPS in SLHost and experiencing fall downs and slow server... now I moved and I check that the VPS is fast and great, but my sites are loading too slow...
I mean the connect time is too long; the time between connect and sending first byte goes from 5 to 12 seconds! My provider can't find what's wrong and I'm a little lost in this

I'm getting a cabinet colocation with a provider and on the sales order there is a setup and re-occurring fee for "cross connect". My rep explained it's for the connection from my cabinet to their switch. Is this a typical charge for colocation? I thought cross connect is for connecting from their facility to 3rd party providers.

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
That's the wordpress .htaccess
What makes me wonder is if we delete RewriteCond %{REQUEST_FILENAME} !-f, it won't work.
As if there is a recursion. However, there can't be a recursion given the [L] thing right?

I have two RedHat EL 4 boxes linked via a cross-connect. One is a web server (10.0.0.3) and one is a mySQL server (10.0.0.2), the interface between them is eth1 on both machines and a second interface eth0 connects to the internet.
I want to use the web server to send queries to the database server via eth1, 10.0.0.2:3306 in this case. If I send a database query via eth1 there is a delay of about 10-20 seconds before the result comes back. If I send the same query to the database server but use it's main IP instead of the internal IP so that the query is being sent to it over the internet (xx.xx.xx.xx:3306), the result comes back instantly.
Similarly, if I send a query from any remote server the result is instant.
Why should there be such a huge delay when sending a query directly through the cross-connect?
The routing table ( ip route show ) for the web server is:
xx.xx.xx.xx/xx dev eth0 proto kernel scope link src xx.xxx.xx.xx
10.0.0.0/24 dev eth1 proto kernel scope link src 10.0.0.3
default via xx.xx.xx.xx dev eth0
and the routing table on the database server is:
xx.xx.xx.xx/xx dev eth0 proto kernel scope link src xx.xx.xx.xx
10.0.0.0/8 dev eth1 proto kernel scope link src 10.0.0.2
default via xx.xx.xx.xx dev eth0
I have ifcfg-eth1 on both boxes:
DEVICE=eth1
ONBOOT=yes
TYPE=Ethernet
IPADDR=10.0.0.3 / 10.0.0.2
NETMASK=255.255.255.0
Both boxes can ping each other and transfer files using wget without any apparant problems or delays.
Anyone have any ideas on how to fix this 10-20 second delay when sending queries through the cross-connect?

I have two VPS's, VPS1 has one vbulletin community. VPS2 has about 10 cpanel accounts, mostly email, a blog site, etc. Both VPS's well under 10 gig in size not including any backups stored on the VPS.
For the more important VPS, VPS1, I am packaging the cpanel account (50mb) and SCPing it to VPS2.
I am also running pckgacct on the cpanel accounts on VPS2 (about 2 gig total, 1 tar.gz is 1.5gb, three others around 250mb, others smaller) and storing them on VPS2.
I then have WS_FTP scheduled to download the cpanel tar.gz files each night to a local machine.
I also have WHM setup to do daily incremental backups, but am not moving any of these offsite.
So, it seems I have three options:
Keep doing what I am doing.
Keep moving VPS1 tar.gz files to VPS2, but also start moving VPS2 tar.gz files to VPS1.
Start moving tar.gz files (or raw files with rsync) to offsite storage.
I'm curious on some feedback about the three options. These are personal sites, I am not reselling any sites/packages.
It seems like from a data security standpoint (email and stuff), the more 'locations' introduced into the loop, the less security there will be. Does anyone get concerned about moving their email and other data to offsite storage services?
As I said, I have a technical solution currently working, but I am wondering about the theory/data protection aspects of the various options for going forward.

I'm trying to set up a login script on twenty subdomains that will be checked on another subdomain. I've found this example for different domains and figure it should be simple enough to utilise but my ereg is crappy

apperently cPanel does not wish to fix a cross-site request forgery because it would be a so called feature. Maybe due the weekend someone had a drink to many
Anyways ; from The register:
Quote:
The vulnerability in cPanel is triggered by luring a user to a malicious website while logged in to the program, which is one of the most widely used web-hosting applications.
The attack is able to trick cPanel into carrying out sensitive commands by making it appear as if they came from the victim.
"If you logged in as root and you hit my website or you hit any website I control, I can do anything I want," Bailey said. "I can reset your root password, I can upgrade software, I can modify any setting I want. That's scary and that's bad."
Even more troubling, Bailey continued, was the reply he got when he notified cPanel officials of the bug. "The response I got from cPanel was we can't fix this because it's a feature. Apparently, they're worried it's going to break integration with third party billing software, so they can't fix this."

I have 2 servers in the same datacenter, 1 serve as web server, and 1 serve as mysql server.

We have following rule in httpd-vhosts.conf and it was working all ok.
All of sudden we have found on one day that it stopped working and we did some configuration tweak with this rule but none of them worked.
During troubleshooting, last change was disabling mod_security and after that it started working again. However, next day we had again enabled mod_security to get issue replicated but found it working all ok.
Any clue for such behaviour of Apache ? Why all of sudden following working rule may get stopped working and then starts working again ?
<IfModule mod_headers.c>
SetEnvIf Origin "https://(www.)?(v1.abc.com|v1ak.abc.com|v2.asite.com)$" AccessControlAllowOrigin=$0$1
Header Set Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
Header Set Access-Control-Allow-Credentials "true"
Header Set Access-Control-Allow-Methods "GET, POST, OPTIONS"
Header Set Access-Control-Allow-Headers "origin, content-type, accept, X-Requested-With"
Header always unset Expires
</IfModule>
OS and Apache Version details are below:
Apache Version :2.2.27(win32), OS: Windows 2008 R2, ModSecurity Rule Set ver.1.5

OP: Linux Centos
I just got an additional 500GB hard drive added and mounted it to /home2
There are files that are in /home1 (orginal HD) that will need to be constantly moved over to /home2 via a ftp
But i keep getting this error
550 Rename/move failure: Invalid cross-device link
Does anyone have any ideas? I tried changing permissions but no luck also tried mounting the 2nd hard drive within a directory in /home1. Still gives the error.
