Does anyone know how to make iptables log to a MySQL database?If you do, can you tell me where I can find a good tutorial?I hope that I didn't ask a question that I could have found easily using Google. I didn't find much or at least not very recent.I am using CentOS 5.4, iptabels 1.3.5 and MySQL 5.0.77.

Dear all, I have system running LAMP and acting as a regular webserver.After running the setup for quite some months, I start having major issues:Symptoms:1. Applications do not respond neither from LAN nor WAN - SSH daemon, Apache, MySQL, FTP2. Network still seems to work for ping and port listeners3. Telnet is still successful for 21, 22, 80, 33064. Server has to be restarted manuallyTrying to find out the issue, I went through /var/log/ looking for major issues or warnings. But nothing seemed plausible to me to understand the issue - except I knew I was running out of disk space a few times.Not being able to identify nor replicate the issue, I replaced the hardware running 24x7 since quite a few years. Doing this, I migrated at the same time from OpenSUSE 10.1 to 11.3.The machine itself is behind a firewall and only the above mentioned standard ports are accessible
View 4 Replies View RelatedI 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. I went about installing it thinking that it would all work. But it seems that I was wrong. So I try to start mysql, and here's what I get:
Code:

I've got a machine running Ubuntu Server that is on several VLANs. Each VLAN has its own subnet and the server has an address on each subnet. The switches are set to allow tagged traffic to the server for each VLAN that it is on. Switch ports ending with workstations are given untagged ports on whatever VLAN is appropriate. Workstations are given addresses on a subnet for each VLAN via DHCP. All this works great and hosts on any subnet/VLAN can access the server as normal via its address on that subnet/VLAN.
Accessing the machine by its address on a non-local subnet is where I run into a problem. Inter-subnet traffic has to go through a router, which has been set up appropriately. Running tcpdump on the server and pinging it from a workstation on a subnet, using its address on a different subnet, shows the server receives the ping, but sends no response:
Code:
sudo tcpdump -i vlan4 -n
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

I am connecting servers using NFS4 the shared directories are on servers running Debian 4 while the one who read from them is Debian 5.0.3. The problem is one of these shared servers suddenly stop responding and you cannot list it from Debian 5 server, also df hang, and the web application that is using it does not respond to requests that use this shared directory since it is blocked. Then the load on the server start to increase until the server cannot respond (over 90). I have found many entries in the syslog that refer to this like:
ma25555 kernel: [1200285.732919] nfs: server 10.xxx.xxx.xxx not responding, still trying
Dec 31 08:16:33 ma25555 kernel: [1200289.815378] INFO: task java:9702 blocked for more than 120 seconds.

I have tried the connection between the 2 servers using ping for one day and all are OK (zero lost)
There are 3 other servers that are running Debian 4 and are working fine.
I have installed Mysql in Ubuntu 9, for the use of roundcube database.After installing iam getting the error like this
* Stopping MySQL database server mysqld [ OK ]
* Starting MySQL database server mysqld [ OK ]
* Checking for corrupt, not cleanly closed and upgrade needing tables.
So because of this in the roundcube configuration its giving the error message that MYSQL is not installed. So Kindly give me a idea how to solve this.
I'm having problems connecting to the mysql database on my system. I first noticed this when I was trying to set up the program anymeal. I subsequently tried using MySQL Administrator (mysql-admin), but had no luck. It gives my the following feedback:

Click the 'Ping' button to see if there is a networking problem. I press the ping button, and it seems to connect.

I've been attempting to set up a LAMP for local web development, which meant installing mysql-server. But now have a problem when trying to run mysql, I get:-

When trying to downgrade mysql-server I saw that there are dependency problems between the various modules (but can't recall which). But whichever route I truied the results are always the same.
Thought about trying XAMPP but I note that even has it's problems, is there any way I can get a lamp set up on FC14, or must I give it up as a bad job.
Howver, just been trying to again to fix the problems with downgrading mysql and get:-
Error: Package: mysql-server-5.1.55-1.fc14.i686 (@updates)

I have problems with nfs. There is an old legato cluster Automated Availability Manager on Linux. And lately we noticed problem with nfs
in the logs there are still entries:
I tried to add more threads in /etc/sysconfig/nfs but it didn't help.
And on one node there is info regarding double mounted filesystems with df -h command. Why? In /etc/fstab is only one entry.
I was having issues with MySQL Server and uninstalled it. I still have my databases at /lib/var/mysql.
My question: if I install MySQL Server (same version, 5.1) again, will it delete my databases, or will they still work?
How can I really, really remove everything related to mysql / mysql-server. I read and tried all kinds of things, but on every reinstall there is still old mysql stuff there, for example an existing password. Even resetting the password does not help.
Reason of removal: it looks like the mysql setup is really corrupt, so I want to remove, and then do a fresh install. Running Ubuntu 11.04 64-bit
sander@R540:~$ sudo apt-get purge mysql-server

I installed mediawiki the other day and went with the default innodb option. However a week later something went wrong. And since I have scripts that nightly backup /var/ I just copied the backup of /var/lib/mysql/wikidb/ (as I've done with MyISAM). Then when I connect the wikidb database. I can see the tables (via "show tables"), but when I do any query with them (check table X, select * from X) I get:
Code:
Table 'wikidb.X' doesn't exist I've since read that can can't just copy the database directory like MyISAM, and there appears to be no way that I can find to restore or fix Innodb, without a dump of the data. And I never got a chance to do a mysqldump of the data. So has anybody got any idea how I can at least view the "page" table from the files I've backed up in /var/lib/mysql/wikidb/ ?
I just configured a complete Cent OS 5.2 system for use as a web server. I can configure Apache and PHP but MySQl seems to be causing some issues -

I am using CentOS5 and installed the MySQL for server during the installation. I can set up and use MySQL databases. But I cannot make it startup everytime the server restarts. And quite a lot of methods need this folder "support-files/mysql.server", while my set up cannot find this. I am wondering if my installation of the MySQL for server is complete or not.

I need to hard reboot server to get it back online. This is happening very frequently in fact yesterday and today server went inaccessible. which log file should I look into to find out the reasons of this inaccessibility?

i m experiencing some problems connecting via ssh two ubuntu workstation: a ssh client and a ssh server The goal of that is to run from local client computer some X applications on the remote server machine
i have configured both client and server for X11forwarding (i think) properly Infact when i launch xeyes on the client i see the X app running
the problem is for all other X apps. For example when i run xclock, nothing happens on the local PC the prompt continues blinking without any reponse, no windows opens and the strangest thing, the shell is stucked. No possible to interrupt with [CTRL]+c the onyl thing to do is close the shell window
Starting in verbose mode (debug), X11 seems works correct , it says x11 confirm as last message .

I recently decided to install Ubuntu and I went through all of the steps to set up a subversion server using svnserve. It all works except for one thing: it stops responding to remote computers after a while.I have the server on a 4 port wireless router/switch in my dorm room. I set up port forwarding so that the server receives all traic over the correct ports. The subversion server AND the default http server on Ubuntu work fine always as long as I access them from a computer connected to the switch in my room.The problem is that if I try to access it from anywhere else, it won't respond at all unless it has been accessed by a computer on the switch recently (something like 30-60 minutes). So to fix it I have to go back to my room and access it from a computer on the switch. Then it will work from anywhere for another 30-60 minutes.

after a update to 5.3 from 5.2 via the built in updater the system stops responding to visitors from the outside, http that is, but heres the odd part, if i say run firefox on the server the connection works also for some reason if i'm on the network with my own computer the connection seems to stay open but as soon as i stop using these the server seems to drop the conenctions, but as i said as soon as i go via my comp to the server via say ie it works right away.
this i tried yesterday:did a cold boot to see if some update had problems and actually needed a reboot even if the updater didn't say, after it started the connection seemed to be open for a good while, and not untill this morning from a outside source the connection is droped again, not been on my comp nor logged on on the server today yet.the install only has on it what i got from the dvd, and as far as i know it has all the updates on it since 5.3 came out.my network is built up like this:
