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'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.
i am about to sign up for equinix's colocation service in LA. I am just curious if anyone else is paying similarly outrageous cross connect fees.. they are charging $300 for ethernet, and $200 for DS3.
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.
I have the following problem with a CentOS server:
The main IP of the server is yyy.zzz.www.qqq
We've just purchased 3 additional IPs: aaa.bbb.ccc.100, aaa.bbb.ccc.101, aaa.bbb.ccc.102.
First, all outgoing traffic used aaa.bbb.ccc.100, but after deleting the gateways from the additional IPs it seemed to work fine, until we found out the following:
Now all traffic to aaa.bbb.ccc.XXX uses aaa.bbb.ccc.100 as outgoing IP.
What command would change this to use our main IP?
how to configure linux so that it allows for two ip addresses on one machine?
I know this is possible because my server administrator setup one of my servers to have two different ip addresses so that I could have a static and dynamic http daemon (two different daemons but listening on different ips).
I have a windows 2003 server machine. This machine has 3 internet IPs.
Im running Microsoft Virtual Server and going to be running 2 virtual machines both running Linux (Ubuntu).
Ideally I would like the 2 VMs to use my spair 2 internet IPs. However they are assigned to the NIC on the real windows server. How can I route 2 of these ip addressess to the 2 VMs?
Baring in mind that the windows server has only 1 NIC (used for the internet)
My Plesk panel (11.5.30) hosts a number of domains that all use Google Apps for Business to host their emails. No emails are hosted on the panel, and the mail server is turned off. So is the DNS server.
Using the mail() php function to send automatic confirmation emails from a website hosted on the panel, they arrive at any address NOT hosted locally, however they fail to arrive at any address whose website is locally hosted.
My initial research suggested that Plesk was routing locally, hence the problem, however the mailserver has been turned off the for domain/webspace.
Since yesterday I can't connect to any of my ftp clients.For months I could login to my FTP using Coda and Filezilla and everything worked until yesterday.
Coda gives me this message: Error -203: miscellaneous error occurred while trying to login to the host
Filezilla gives me this message: Antwoord:220 ProFTPD 1.3.5 Server (ProFTPD) [MYSERVERIP] Opdracht:USER username (username is my ftp username) Antwoord:550 SSL/TLS required on the control channel
I have not changed anything on my server. Just out of the blue this errors appears and now my customers and I can't login anymore.I tried to restart the server, made a new ftp account..I don't know if I can reinstall the ProFTPD or need to open port 21?
I can not connect to the server with using "Require explicit FTP over TLS"
In /etc/proftpd.conf I have added from here [URL] ....:
<IfModule mod_tls.c> TLSEngine on TLSLog /var/log/tls.log TLSProtocol SSLv23
[Code]....
PS: in Tools & Settings ->SSL Certificates ->I created a new self-signed certificate, set as default. In Tools & Settings ->IP Adress bind new certificate to IP
For each domain is created own certificate, but when try to connect, will be ascked to confirm a default certificate from Plesk I have create a new certificate (using SSH)
Service restarted too with: service sw-cp-server restart
i then used a MD5 generator to input the hash in the password field of the roundcube user in mysql, with no luck...I even tried to delete roundcube user from mysql, then remove psa-roundcube, then go through the plesk update manager and install roundcube again, did not change nothing, it didn't even create the roundcube user.
Is there anyway i can reinstall roundcube from scratch?PPP 11.5 up to date on ubuntu 12.04
Code:
[05-Oct-2013 14:03:54 +0200]: DB Error: _doConnect: [Error message: Access denied for user 'roundcube'@'localhost' (using password: YES)] [Native code: 1045] [Native message: Access denied for user 'roundcube'@'localhost' (using password: YES)]
How to connect nginx to work with directory web_users for some virtual host?
This directory contains two accounts (user1, user2) with a large amount of static content (files .jpg), the downloaded web users themselves. At the moment they are processed by Apache, which causes an additional load on the server.
In hosting configuration for virtual host "domain.tld" set:
document root: httpdocs. (That is, the "httpdocs" and "web_users" directories are on the same level).
In the web server configuration settings (in additional nginx directives) i can't use the directive "server" (refuses to save), where you can specify the location of the additional "document root" for nginx.
After changing my web hosting (same system : VPS, same version of linux : CentOS 6 , but passage from Plesk 11 to 12), i am now unable to connect remotely via TCP-IP to my mysql databases (with third-party tools like Mysql Workbench, Toad...) ! I never met this problem before.
The only way to connect is to use a "Standard TCP-IP over SSH" connection method ... but i don't want (i did'nt need this method before) !
Though, remote connections are allowed from any host in the settings.
I recently upgraded to 12.0.18 and I am using Roundcube 1.0 from the panel. I read that the "Unable to connect to sieve serve" problem would be solved in version 12.It seems not. What to do?
I am having trouble connecting to my ssh server. It responds with a lengthy error message about no network etc. but it is the last message that concerns me:
Sometimes, such troubles can be caused by a misconfigured firewall.
How can I check the firewall if I cannot connect to ssh? I am running plesk 11.5 control panel and CentOS 6. Is this something I can do from plesk?
I can see that the firewall in plesk is set to allow all for ssh, but I cannot see way to disable the firewall to test ssh connection. Can this be done from plesk?
I have over 5 WP installations on my Server and i installed all manual and had never issues.
Now i installed a again a WP Site and after i go to the Wordpress Toolkit to search for the new installation i got the following Message:
PHP Parse error: syntax error, unexpected '?' in /usr/share/plesk-wp-cli/php/wp-cli.php(23) : eval()'d code on line 1 {"err_code":0,"err_message":"
With error cannot connect to DB.
So all WP installations are running fine instead of the new one.... I didn't change any configs files of PHP all is standard, the wp-config.php is correct, the Site is running fine.
From my point of view is this an issue by Plesk due to Parse error message at the files of Plesk, see error message!
System: OS Debian 7.8 Plesk Version 12.0.18 Update #43, zuletzt aktualisiert: 20. April 2015 13:17:36
I know with an older Version of Plesk 12.0.18 it was working fine too, so the bug was implemented with a MU.
I checked the file as well and find out that at all PHP files the code is not closed at the end so the "?>" is always missing.
I had Plesk 10 installed on my openSUSE system (was a low version, maybe 11 or less) and then decided to upgrade to 11.5. So I did distribution upgrades to openSUSE 12.3 and everything went smoothly, except for some services like mysql and php. So I used Plesk autoinstaller to fix the php error and edited an outdated line in mysql configuration and both services ran smoothly!
Then I downloaded Plesk autoinstaller and ran the autoinstaller, but was surprised by this error message:
===> Checking for previous installation ... found. ERR (3) [panel]: Error during product key mode determination, details: Unable to connect to database: ; trace: #0 /usr/local/psa/admin/plib/functions.php(2821): isPpaKeyRequired() #1 /usr/local/psa/admin/plib/common_func.php3(11): require_once('/usr/local/psa/...') #2 /usr/local/psa/admin/plib/api-common/cu.php(5): require_once('/usr/local/psa/...') #3 /usr/local/psa/admin/sbin/httpdmng(8): include_once('/usr/local/psa/...') #4 (main)
Unable to connect to database:
- My MySQL version is: 5.5.33 openSUSE package - I did run mysql_upgrade with my admin username and password (password from: /etc/psa/.psa.shadow) and it worked successfully and fixed all of the errors, I did so after running the auto installer first, but then ran the installer again and the problem was still there - I can access my web page, but it still doesn't connect to MySQL either.
I believe this is a problem with MySQL, but how can I make sure or detect what exactly the problem is
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 cant connect to the Database WebAdmin. If I click the icon, i got an "File not found." in the opening tab. Back in Plesk I get the following:
ERROR: PlexkFatalException Server id is undefined?
I even cant connect via ssh to the mysql part of my server. But the server is running and both of my two wordpress pages run smoothly. I know this page: [URL] .... – but as I sad, cant enter die mysql.
It seems something is wrong with the permissions. I'm on the point where I just want to reset everything database related. But how?
On IIS6 many of thesite are under cross scripting attack I tried by remove the the code but it affects again after some time I reset the ftp password and passowrd is a combination of complex alpna numeric character.I have cheked the permission it is ok.
