Just a quick note and warning is that if you are testing to see if EFIPXE booting works on a VM, MAKE SURE it actually works. For example Iinitially tested using my Distro's QEMU 2.5+dfsg-5ubuntu10.46 and ovmf BIOS firmware (OVMF supports EFI). However, I found on old versions of QEMU (like 2.5), EFIbooting with GRUB NEVER works so it may appear that you have made a mistake when everything is fine when you boot a physi........
It is very silly but the default on the ifup-eth script tells dhclient ( the program that obtains a DHCP IPaddress if you have selected DHCPin your ifcfg-eth* config file) to EXIT / QUIT if the first attempt to obtain a lease fails.
No amount of dhclient.conf settings will fix this because if dhclient is started with -1 (which it is by default)then dhclient will quit.
This is obviously very bad for MOST cases. Say for example you have a power outage or........
Cisco's CUCM (Cisco Unified Communication Manager) is a system that combines voice, video, data and mobile products into a single unified management suite. At its core, the CUCMis like a "Super PBX" that controls the flow of all communications through an organization even single or multiple site deployments.
Cisco's CUCMmakes communication more effective and simple through centralized management and unification of communications resources.........
1.) Flash directly to this file:
*I was never able to get the larger "Mega" file to work, at least not initially so I recommend the file above.
To enable 5ghz I had to do the "Clear NVRAM" Option before it was shown.
2.) Or if you don't need 5ghz (most devices do not support it and cannot........
This is just trying to read 5GB off the drive with dd and the drive initially tested ok but shortly after I wondered why I was seeing 2MB/s read speeds. Notice the "current_pending_sector", anytime I've seen it at anything above 0 even with no other bad fields/attributes, it means the drive is bad.

Have you ever seen this dreaded message in your Apache/HTTPD /var/log/httpd/error_log?
[error] server reached MaxClients setting, consider raising the MaxClients setting
The error itself is slightly misleading. Ibelieve this happened to one of my servers, I found Apache was running still, and that you could telnet to port 80 but no respnose would be given.
For some reason my error log initially did not have the above error, but after a restart I saw........
This is really something the SSHServer developers should consider. The cause of this annoyance is because of failed DNS lookups on your IPaddress, which is especially common for many dedicated/col-located servers and also computers on internal NAT/private networks.
The chances are this is the cause of your SSHSlow/Delayed Login problems.
