I have recently set up a zabbix server and am now trying to get data via SNMP from a FreeNAS (FreeBSD) Server. When checking snmp with snmpwalk I get the correct results. So I proceeded and added the snmp-command in zabbix server.
The weird thing: When I set up the Zabbix Item as Character I get the correct Information from the Freenas. When I set it to Number I do not get any Information at all.
Can anybody help ? I am out of ideas.

I'm writing a new project that utilises MySQL , There is no problem with the app I'm working on, but when the app recives the output from my sql server it immediately rejects it as null. When accessing my SQL server on port 3306 I am getting strange garbled messages back as well as the short message 'packets out of order.' In my setup I have, MAMP, Docker, Apache server and PHP. I can access each service on its respective port just fine.
1) I have looked into this by running console in the browser which reports the text being incorrectly formatted to something that isn't utf-8
2) I have followed this guide
https://medium.com/#manish_demblani/breaking-out-from-the-mysql-character-set-hell-24c6a306e1e5 and the results that my sql server have churned out are as follows
enter image description here
My question is this. Why is MySQL set up in this strange fashion? Why is it presenting in CP850 /DOS/ Latin? Are there no defaults/config files to change or is it done through windows somewhere
It seems you somehow messed up the client configuration (connection string, [client]-section of your cnf file (on the system that you started the mysql console on), ...). It tells your server to send data in cp850. Not sure why you would get packets out of order, maybe you have an additional underlying problem (very old library maybe?), but I'd start there. It's unclear: did you follow the blog post and then had problems, or was that a solution attempt? In any case, try to focus your attention on the client. Try to undo changes you made. MySQL uses utf8 by default for a long time now. – Solarflare
I got problem (#2006 Mysql server gone away) with mysql while connecting and performing some operations through web browser.
Operation Listed below:
When Executing big procedure
Importing database dump
When Access some particular tables It immediately throws "Server gone away".
Refer this question for Scenarios: Record Not Inserted - #2006 Mysql server gone away
Note : The above operations are works fine when I perform through terminal.
I tried some configuration as googing stated. That is set wait_timeout, max_allowed_packet. I checked for the bin_log but it is not available.
But the issues will not rectified.
What is the problem & How can I figure out & fix the issue?
what is the different between access phpmyadmin mysql server from web browser and terminal?
Where I can find the mysql server log file?
Note: If you know about any one of the above questions. Please post here. It would be helpful to trace.
Please help me to figure this out..
Thanks in advance...
Basically nothing except phpMyAdmin is limited by PHP's timeout and resource limits (limits to keep a runaway script from bogging down your entire machine for all eternity; see the docs for details of those values. In some cases, you might be authenticating through a different user account (for instance, root#localhost and root#127.0.0.1 aren't the same user), but as long as you're using a user with the same permissions the differences are minimal.
You can read more about logs in the MySQL manual, note that "By default, no logs are enabled (except the error log on Windows)".
Below are answer for question
From my research the problem is that browser have some limit to disconnect the connection i.e timeout connection. So that the above problem raised.
To resolve this problem
Go to /opt/lampp/phpmyadmin and open config.inc.php
add the command $cfg['ExecTimeLimit'] = 0;
Restart the xamp server. Now you can perform any operations.
`
2. Web client is differ from terminal because Terminal client will not getting timeout. Terminal client maintain the connection till the progress completed. I recommenced to use command prompt to import/export/run process by safe way.
Basically phpmyadmin will not have any log file. If you wanna see warnings and error you should configure the log file.
Configuration steps:
Go to /opt/lampp/etc/my.cnf
Add log_bin = /opt/lampp/var/mysql/filename.log
Restart the xamp server. You can get the log information.
UPDATE queries work fine from the mysql command line, for any user.
However, when any UPDATE queries are run via a web interface (whether phpmyadmin or wordpress), the queries don't work, and I get a "no change" notice from mysql. Most of the time. The query is successful 10% of the time. Thing is there was a change, it just didn't take. I'm using the same user on phpmyadmin as on wordpress as on the command line client. I'm stumped. Anyone been here before?
Server details:
Apache/2.2.14 (Ubuntu)
MySQL client version: 5.1.61
PHP extension: mysqli
PHP version PHP 5.3.2-1ubuntu4.14
Update:
The "no change" notice comes from phpmyadmin. I don't get a "0 row(s) affected" from pma. When I return to the record that I attempted to edit, the edits aren't in there.
In wordpress, if it were a successful edit on a post I would get a "draft updated" or similar message. However, most of the time it just kicks me out to the wordpress admin index of posts without any message, and without any changes saved.
How this was fixed:
Clarified the apache server configuration. It was round-robining between two virtual hosts due to non-specific domain conf files.
The timeout value in httpd.conf was set to 0. This created issues.
I'm using snort in win7.
We know that using snort in its sniffer mode we can log a lot packets
into a file, and now I want to log them to a mysql server. I enabled
the database output plugin in the snort.conf and customed a rule:
log ip any any <> any any (sid:2000000;)
as a test.
Everything is OK and I used a PC whose ip is 172.18.186.186 to ping another 172.18.186.189. What I hope to get is 8 records, among which there would be 4 records and their ip_srces are 172.18.186.186. However I just got 4 records and their ip_dsts are 172.18.186.186 while the ip_srces are 172.18.186.189.
OK,that's my problem. How can I get the 8 records I want to see? Is it possible?
Thanks in advance.
yes, you can check out snorby. and lot of implementation there are for connecting snort to a database, such as mysql or mongodb etc.
This article explaing you how u can log to mysql.
Please look at the output plugin unified2, because direct SQL output is deprecated in the snort tree 2.9.2 and will be removed at some point.
Barnyard2 is a binary capable of reading unified2 output and writing that data to a SQL, syslog, or other datasource.
FYI: Snorby is just a Ruby On Rails web app for a database schema for the ACID/BASE standard.
I got a OSX Server, i updated it to 10.6.5 from 10.6.4.
Since then my Ruby on Rails Application (leihs) gibes me an Error.
"your config/databse.yml may not be written correctly. Please check it and fix any errors.
Your databse schema may be out of date or nonexistant. ....
The database server may not be running. Please check whether it's running, and start if it isn't
Error message:
Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2) (Mysql:error)
Then a looong list of backtraces whitch dont really help me.
The Socket file does NOT exist, and i cant find it on other places.
Please help me, this is making me crazy.
Thanks for your time & help
I appears that your mysql server is not running. You should debug that portion of your system before looking at your rails app.
A few things to checK:
Can you connect from the command line?
Are there startup errors in your mysql log file?
Did you change IP addresses, share names or anything else that might have stuffed your mysql install?
I solved the Problem!
Reinstalling the 10.6.5 Combo Update helped.
-Download the correct Combo Update (same version (server/normal), same build)
-Stop the Services (like Web and so on..)
-Install the Update
-Restart
-Start Services
-All should work again
Thanks to all of you guys for their help.
