Interesting Dutch thread about a major ISP having DNS issues because of DDos attacks. Many messages to set your DNS servers manually on various operating systems, and a list of good DNS server alternatives. Recommended reading:

Interesting: all SonicWALL seem to support multi-WAN (more than 2 WAN) in both Failover and Round robin fashion: SonicWALL Multi-WAN Firewalls (Unlimited WAN).

In the the irregular series of ASUS RT-N66U and TomatoUSB posts:
Execute this script from the Tomato USB interface, or a ssh/telnet shell:
cat /dev/mtd0ro | grep bl_version
nvram get os_version
nvram get clkfreq
wl -i eth1 phy_tempsense | awk '{print $1/2+20;}'
wl -i eth2 phy_tempsense | awk '{print $1/2+20;}'
- Line 1 gets the CFE bootloader version
(1.0.2 and lower boot with 32K of NVRAM, 1.0.3 and up with 64K of RAM; some Firmwares work around the 32k limitation)
- Line 2 gets the Firmware model and version
- Line 3 gets the CPU speed
- Line 4 and 5 get the temperature for eth1 (2.4 Ghz) and eth2 (5 Ghz) in Celsius
It is based on the RMerlinDev (firmware developer) information on temperatures: These are for each radio. Take the returned value, divide by 2, then add 20. Results are in Celcius.
Next to that knowledge, it uses a few tricks on awk calculation, and first parameter in awk (the second parameter would be the hex value of the temperature code in parenthesis) which is easier than shell calculations.
Based on those, I found a few very useful scripts:

I’ve succesfully woken up these machines:
- HP XW6600 running ESXi 5.1
- ThinkPad W701U running Windows 7
I still need to try to wake up a Mac Mini Server running OS X 10.6 (Snow Leopard).
MacBook Air on 10.7 (Lion) and Retina on 10.8 (Mountain Lion) won’t work as they are WiFi only, and WOL does not work over WiFi.
On 10.7 and up it might not work on a Mac Mini Server either, as Apple Introduced Dark Wake.
I used these tools to send WOL packets: Read the rest of this entry »

Somehow my Fonera insisted that WiFi channel 2 was a good choice.
It isn’t so I forced it to be on one of the good 1/6/11 channel choices.
This links describes where those settings are: Fonera Simpl Wireless Settings : Fon Support.

RouterOS runs on many kinds of hardware. Of course on the MikroTik hardware itself (which always comes with a license), but also on x86 hardware, even virtualized systems.
In that respect, it looks a bit like pfSense, or Endian, but on steroids and closed source.
Here are some links focused on MikroTik on ESXi (which is great for experimental purposes):

Interesting: Peplink multi-WAN routers and VPN solutions.
Lets see how this compares to MikroTik stuff (:
