ifconfig & Netmasks
Tuesday, July 29th, 2008Whenever moving IPs around on servers I always find myself looking up the hex for a netmask.
Ever run into this
$ ifconfig inet xxxxxxxxxxx netmask 0xfffffff0 broadcast xxxxxxxxxxxxxx
And need to know what the fffffff0 was for Here it is:
| Dotted Decimal |
Hex | Number of Addresses |
| 255.0.0.0 | FF000000 | 16777214 (16777216-2) |
| 255.255.0.0 | FFFF0000 | 65534 (65536-2) |
| 255.255.255.0 | FFFFFF00 | 254 (256-2) |
| 255.255.255.128 | FFFFFF80 | 126 (128-2) |
| 255.255.255.192 | FFFFFFC0 | 62 (64-2) |
| 255.255.255.224 | FFFFFFE0 | 30 (32-2) |
| 255.255.255.240 | FFFFFFF0 | 14 (16-2) |
| 255.255.255.248 | FFFFFFF8 | 6 (8-2) |
| 255.255.255.252 * | FFFFFFFC * | 2 (4-2) * |
PHP easy timezone set
Monday, July 28th, 2008Here is a quick way to set a timezone:
<php putenv(‘TZ=America/New_York’); >
A list of timezones for php: http://www.theprojects.org/dev/zone.txt
To get the timezones into a file quickly:
wget http://www.theprojects.org/dev/zone.txt
cat zone.txt | awk ‘{ print $3}’ >> timezones.txt
Remove the first few lines and you have an easily read file that you can make a selection box out of.
