I wonder why would companies use non-transparent proxies when the transparent ones seems better to me.
I am using Windows Network Load Balancing to keep my apps available even when one of the servers is down.
The problem is that it only detects when a whole machine is down. It happens sometimes that only one service is down, but its host is up, then the request are still sent to this endpoint but it doesn't answer.
Is there any solution that addresses this problem? There is any way to configure Windows NLB or a third party one to check the status of a specific port?
I have seem performance counters like this:
PhysicalDisk(_Total)\Avg. Disk Read Queue Length
Which is an aggregation (average, sum, etc) of data over a period.
How to create a custom counter which is an aggregation of existent data of another counter?
I was thinking of instead sending data to Zabbix Trapper I could send to Windows Performance monitor and then capture it using Zabbix Agent. Is it possible? How?
If a variable is expected to be fetched every minute, and it doesn't happen, the graph shows the last known value for all the timespan until the next known value.
The expected behavior for me is that the graph showed no line, or a line next to the zero, where there is no data.
How to achieve this with Zabbix?
I'm trying to configure mercurial access using Apache http.
It requires authentication. My /etc/apache2/sites-enabled/mercurial looks like this:
NameVirtualHost *:8080
<VirtualHost *:8080>
UseCanonicalName Off
ServerAdmin webmaster@localhost
AddHandler cgi-script .cgi
ScriptAliasMatch ^(.*) /usr/lib/cgi-bin/hgwebdir.cgi/$1
</VirtualHost>
Every tutorial I read on the internet tells me to insert these lines:
AuthType Basic
AuthUserFile /usr/local/etc/httpd/users
But when I do it I get the following error:
# /etc/init.d/apache2 reload
Syntax error on line 8 of /etc/apache2/sites-enabled/mercurial:
AuthType not allowed here
My distro is a customized Ubuntu called Turnkey Linux Redmine
I created a Debian Lenny virtual machine as described on the manual. How to control it?
It has no IP since my LAN has DHCP disabled. If it only had a static IP and SSHD enabled I could just PuTTY it.
Turnkey Linux distributes Linux virtual machines in a Xen compatible format. I have a XenServer instance running and I would like to run a recently downloaded Turnkey Linux virtual machine on it. But I have never used XenServer before.
Can you point me a tutorial specific for this case, since the manual doesn't seem to cover it very well?
I know many folder synchronization tools for desktop users (ie. Windows Live Sync)
Should I use them to synchronize applications between servers or there is a more enterprisey solution?
I am installing a MySql server in Ubuntu desktop. I could connect MySql Query Browser to it when specifying the Server Hostname as localhost, but when I replace it by the machine's IP it stops working (even if the MySql Query Browser runs in the same machine).
All I have done so far is removing the iptables, but it seems it have nothing to do with it.
Here is the error message
Could not connect to host '192.168.0.2'.
MySQL Error Nr. 2003
Can't connect to MySQL server on '192.168.0.2' (111)
Click the 'Ping' button to see if there is a networking problem.
The ping is ok, though
In the case of Operation Enduring Freedom and Iraq Wars the Internet suffered minor hits from those minor powers isolation or absense.
But what would happen if major powers start a war? A Netsplit? Would a major power isolate himself from the world as a security measure against eletronic attacks? If yes, it would be a physical disconnection or a logical one?

At my workplace, our servers have run 64-bit OSes for years. But the workstations are a problem. Very few applications and drivers work well on 64-bit OSes. Those few cases are enough to prevent the deployment of 64-bit OSes on workstations.
- Why does that happen? Is it the OS or driver/application's fault?
Additionaly:
If you have a similar problem please share your thoughts and problems you experienced.
When will 64-bit OSes be a majority?
