Some helpful scripts I wrote... leech them here.
First one...
PHP Code:
#!/usr/bin/perl
# SplitInfinity Networks, INC.
# 858-560-2760
# Programmer: Chris Jester
# [email protected]
# This program is free to use, but not to sell.
# Enjoy.
# Compatible and tested on Fedora Core 1,2,3 etc.
# As well as any other Linux that uses /etc/sysconfig/network-scripts
# as a mechanism to add ips and etc. Redhat, Suse, Etc.
# This shell script, was created for admins to easily
# add many ip's to one server. Make a list of the IP's
# in a file called iplist.txt which is to be created
# in the same directory as the one this program resides
# in (unless you modify the paths below).
# Run the program from the shell prompt like this:
#
# ./makeips.pl START_WITH_WHAT#
#
# Where START_WITH_WHAT# is the number of the first interface
# you wish to begin with. So for example, if you have already
# assigned ethernet 0, 0:0 and 0:1 then you will want to add
# interfaces beginning at 0:2 so you would enter 2 there to
# make sure the numbering is correct and your new interfaces
# are created correctly. If you are adding interfaces to
# a system with more than 1 ethernet card, then you must
# specify the card by changing the variable below.
#
# Props: Special thanks to Swami who inspired me to write
# this quick hack. Customers make the world go round.
# My scripts make it happen a bit faster. Thanks.
$interface = $ARGV[0];
$card = "0";
$directory = "/root/test";
#$directory = "/etc/sysconfig/network-scripts";
$iplist = "./iplist.txt";
open(DB,"$iplist");
while(<DB>) {
# Template of the ip configuration file
$template = <<__END_OF_FORMAT__;
DEVICE=eth<<CARD>>:<<INTERFACE>>
ONBOOT=yes
BOOTPROTO=static
IPADDR=<<IPADDRESS>>
NETMASK=255.255.255.0
GATEWAY=<<GATEWAY>>
__END_OF_FORMAT__
$ipaddress = $_;
chomp($ipaddress);
($oct1,$oct2,$oct3) = split(/\./,$ipaddress);
$gateway = "$oct1.$oct2.$oct3.1";
$template =~ s/<<IPADDRESS>>/$ipaddress/g;
$template =~ s/<<INTERFACE>>/$interface/g;
$template =~ s/<<GATEWAY>>/$gateway/g;
$template =~ s/<<CARD>>/$card/g;
open(FILE, ">$directory/ifcfg-eth$card:$interface");
print FILE $template;
close(FILE);
$shell .= "ifup ifcfg-eth$card:$interface\n";
$interface++;
}
print $shell;
print "\n\n\nCopy the above commands and paste into shell to bring the new interfaces up.\n";
Second one...
PHP Code:
#!/usr/bin/perl
# Another script to make my life easy.
# Purpose: Lets say you have a bunch of domains to add to a
# name server. And each domain is to have its own settings...
# This script takes a file input in the following format:
#
# domain.com ns1ip ns2ip
# Where ns1ip is the primary ns and ns2ip is the secondary ns.
# This script will create all the zone files and spit out
# the entries to add to named.conf to make those zone files
# active.
# It will use ns1ip as the web server ip address. (since thats
# what I needed it to do when I wrote it. )
# Enjoy
$directory = "/var/named";
$domainlist = "./domains.txt";
open(DB,"$domainlist");
while(<DB>) {
# Template of the ip configuration file
$template = <<__END_OF_FORMAT__;
\$TTL 1800
\@ IN SOA ns1.<<DOMAINNAME>>. si-support.splitinfinity.net. (
2005043100 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
1800 ) ; Minimum
IN NS ns1.<<DOMAINNAME>>.
IN NS ns2.<<DOMAINNAME>>.
IN MX 5 mail
A <<NS1IP>>
IN A <<NS1IP>>
mail IN A <<NS1IP>>
www IN A <<NS1IP>>
ns1 IN A <<NS1IP>>
ns2 IN A <<NS2IP>>
* IN A <<NS1IP>>
__END_OF_FORMAT__
$input = $_;
($domainname,$ipaddress1,$ipaddress2) = split(/\t/,$input);
chomp($ipaddress2);
$template =~ s/<<NS1IP>>/$ipaddress1/g;
$template =~ s/<<NS2IP>>/$ipaddress2/g;
$template =~ s/<<DOMAINNAME>>/$domainname/g;
open(FILE, ">$directory/$domainname.zone");
print FILE $template;
close(FILE);
$shell .= "zone \"$domainname\" {type master; file \"$domainname.zone\";};\n";
$interface++;
}
print $shell;
print "\n\n\nCopy the above commands and paste into named.conf.\n";
