I sometimes get my webserver blocked by my mysql server because of "to many connection errors" and have to use flush hosts to solve it, i now wonder if there is any way to increese that connection error value so the webserver wont get blocked ?
View 1 RepliesI've recently turned an older PC into a linux box for the purpose of creating an online server with ftp and ssh capability and file sharing. I've installed Kubuntu 9.10 and I'm trying to ssh to the computer from outside the network.I've install the openssh-client and openssh-server and I've created a static ip address, which works fine. I cannot ssh to the machine from outside the isp using either the direct ip address or hostname. The machine is connected to the internet via a Linksys Wireless G router, and I've edited the configuration settings to keep port 22 open for connect in the port server utility.
I've checked the ssh_config and sshd_config settings and port 22 is the default connection port, which is supposed to be open. I've run ifconfig and everything looks fine. I can connect to the computer using a machine connected to the same router, but other computers cannot access it. I want it to be visible to everyone.
I see tons of these in my dmesg, and it's causing my virtualbox vms to crash with disk IO errors. It's only affecting the Linux guests. What would cause this?
Code:
INFO: task tar:1865 blocked for more than 120 seconds.
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

I have a fresh installation of CentOS 5 I'm using for a server, and I'm having issues with port configuration. I have iptables running, and it started with no /etc/sysconfig/iptables file. I added a few basic rules (port 53, port 10000 for webmin), saved the file, and restarted the service. I tried connecting to webmin, scanned ports, and traffic was blocked. I set iptables to allow all traffic and restarted the service, and it still showed basically every port as being blocked. It seems port 80 and port 22 work for some reason, even when I tell iptables to block all ports.
I'm not sure what's going on here. Iptables is reading the /etc/sysconfig/iptables file, and if I use lynx localhost:someport it responds as it should according to the file. However, if I try connecting by IP, it's like there's some other firewall or something running that does whatever it's configured to do.....
We have 2 servers, 1 is the webserver and the other is the Mysql server.
When transfering a 2GB file from the webserver to the Mysql server.
The webserver's connection to the mysql DB server dies completely.
Need to restart the MYSQL process in order for it to come back online.
During this connection downtime, when using phpmyadmin on the mysql server shows no problem running queries etc.
Ok let's say I have Apache Webservers on 2 different machines within my network, I have http://outterABC.com setup at dyndns.org to point to my modem at home, and my router forwards Port 80 to the ServerA Machine (i.e. 192.168.0.3). I can access my webpage I setup for the Server A Machine.
But what I want to try and do is somehow access my ServerB machine's website that is on my same network. I tried something like this http://ServerB.outterABC.com and the apache page came up with something like the page wasn't available. I want to access the content of the ServerB website, but because I have only one router, i can only forward Port 80 site traffic to my ServerA machine's website. I'm sure it's a different syntax I should use but i'm just not sure what I should enter to bring up the apache root web page for the Server B website via http://outterABC.com
I tried setting up DNS A records on ServerA, but I don't think it will work with what i'm trying to do above.
I'm unable to install this package, tuxpaint.I get errors in that it cannot reach the proper url or connection to the server?Not sure what I'm doing wrong.I figure the repo is correct and I thought I had the proper source since I've installed other packages.What could be wrong?

I'm dealing with two dedicated servers hosted at liquidweb. The basic idea is that one machine might not be enough to handle the traffic at launch so we have a second machine to shoulder the MySQL duties -- it seemed a natural way to divy up computation burdens.
The support staff at LW tells me that each machine has three network cards
1) Public-facing NIC through which all public visitors are served
2) NIC on LAN so that liquidweb can access the machine locally for maintenance and support
3) Third NIC so that the two machines can speak to each other rapidly on their own private network. Apparently the two machines are connected via crossover cable.
It's my understanding that machine 1 has IP of 192.168.0.1 on this third card and machine 2 has IP of 192.168.0.2 on its third card. For some reason, these machines cannot speak to each other using ping, telnet, ssh, http, or MySQL.
I've contacted tech support about this issue but was wondering how I might be sure that the MySQL traffic transits the third network card on each machine. I'm guessing that it's just a matter of using the third card's IP addresses but want to be sure. Is there any way to specify a NIC when connecting via MySQL?

View 4 Replies View RelatedI have a machine running with slackware64 13.1 and vnc servers is installed on it. It worked for months until yesterday, when I couldnt connect to the machine remotely.
I have 2 vnc "users" on this machine, root and "user". Each have their own desktop. Root has desktop :1 and user had desktop :2. Simple enough.
VNC servers is started via /etc/rc.d/rc.local with the command:

It worked flawlessly. I use the very same configuration on my home server, never had a glitch.
From the "distant" machine, I get this error when I try to connect:
Code:

What has changed so it no longer works? I assume its not a network problem since the machines are all located in my home network and there is no firewall or router in between them.
I'm try to setup a database server using mysql, the server starts fine, and I can access it using the built in mysql client via console (adding databases and tables works fine), but the problem is... I always get a connection refused error whenever I access the database outside the built in mysql client (example, if I write a code that connects to mysql). So, I tried execute an nmap command and the only ports open are these ports:
[Code]....
there's no 3306 for mysql... I'm thinking that the firewall is just blocking the port that mysql is using, but my question is, how could the built in client connect to the server if there's no open port for mysql server? Don't clients usually access a servers through ports?
I'm running a linux cloud server with the following config

The site loads slow and clicking a link almost freezes the page for a second. Also, the page loads could be much faster. We've been running mysqltuner and have pretty much optimized all slow queries. Is there anything we can do to fine tune the server for faster and more responsive?

I think this goes here, but I'm not sure. I decided that XAMPP had been troublesome enough. MySQL never worked. So I decided to instal the LAMP stack offered by YaST.

Linux printing appeared to be working fine up until yesterday. Today typing lpq gives the following: lpq Printer 'sdst@other.domain' - cannot open connection - Connection timed out Make sure LPD server is running on the server
The /etc/cups/printers.conf file is properly set, the printers appear in localhost:631 and they are printing test pages. However, all command line print commands seem to be trying to print to sdst@other.domain I don't know why printers.conf is being ignored and why and how sdst@other.domain was added. Seems like it might have been auto-discovered?
# dit: sdst@other.domain was mentioned in /usr/local/etc/lpd.conf I'm not sure why lpd.conf is being used instead of /etc/cups/printers.conf
