Add Multiple IP Addresses to a Windows Server From the Command Line

Say you want to add 192.168.1.2 through to 192.168.1.14 with a /28 netmask (255.255.255.240).

for /L %a in (2,1,14) do netsh in ip add address "Local Area Connection" 192.168.1.%a 255.255.255.240

Which is:
for /L (tell for that it's a range of numbers)
%a in (placeholder variable)
(start, step, end) (self explanatory)
do (command goes here)

This page FOR /L has more detail and is part of this very useful site ss64.com

YumRepo Error: All mirror URLs are not using ftp, http[s] or file

A very old server that had a service dependant on CentOS 5 Running any yum command resulted in yum check-update Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile YumRepo Error: All mirror URLs are not using ftp, http[s] or file.  Eg. Invalid release/repo/arch combination/ YumRepo Error: All mirror URLs are not using ftp, http[s] or file.  Eg. Invalid release/repo/arch combination/ YumRepo Error: All mirror URLs are not using ftp, http[s] or file.  Eg. Invalid release/repo/arch combination/ The answer was that the mirrorlists needed to be updated to point at the last version of CentOS 5.

Linux: Permanent CIFS/SMB mount

I needed to permanently mount a directory on a Windows server that had spaces in the path. I also wanted to use a credentials file so that the remote server username and password would not be in the world readable fstab file. The following was cobbled together from: Mount samba shares with utf8 encoding using cifs and: Mount password protected network folders Create a credentials file (as root) containing the username and password and restrict it's ability to be read by other users (/etc/fstab is world readable). vi /root/.smbcredentials username=someusername password=somepassword Save and exit the file. Change the file permissions to only be readable by root. chmod 600 /root/.smbcredentials Update the fstab file Add the following line to /etc/fstab (spaces are replaced with \040  or the mount will fail) // ip address / c$/Program\040Files/Microsoft\040SQL\040Server/ /var/backups/Server cifs credentials=/root/.smbcredentials,iocharset=utf8,sec=ntlm 0 0 Exit and s

Plesk - Decrypt FTP Passwords

I was working on a project where Plesk user details were being imported into a database and it would help to know the password. Since Plesk 11 the Plesk Client account is hashed which makes it unrecoverable, but other passwords are encrypted with 128 bit AES encryption and a salt. If the FTP login name is the same as the client login there is a chance the customer was lazy and used the same details. To decrypt the passwords you will need the server secret key and the password string from the plesk database. The server secret key can be retrieved with the following command on a linux server: cat /etc/psa/private/secret_key | base64 Matching FTP logins (and their encrypted password) can be retrieved from the Plesk database with: SELECT REPLACE(s.home, '/var/www/vhosts/', '') AS domain, c.login, a.password FROM clients c LEFT JOIN sys_users s ON s.login = c.login LEFT JOIN accounts a on s.account_id = a.id; The results will look like: +-------------------
