Setting the session timeout parameter in a cisco router or switch is an easy task that will make your day to day work easy.

How to set the session timeout:

log on to the router and type:

router#configure t

router(config)#line vty 0 4

router(config-line)#session-timeout 10       —- 10 is the amount of minutes we want to configure before timeout.

router(config-line)#exec-timeout 0                    — this is when we log in exec mode ( 0 is never)

Create New User \ Mailbox Script Using Exchange 2007 Shell

With Exchange 2007 we have the option to manage our Exchange Server using the Exchage Managment shell which done using commands (cmdlts).

This script is for creating a single user mailbox and an AD user using the shell.

The script called newuser.ps1

Just copy and save the file as newuser.ps1 and don’t forget to change the server and OU details.

$UPN=Read-Host “upn”                 -System.String
$Alias=Read-Host “Alias”              -asPlainText
$Name=Read-Host “Enter Name”   -asPlainText
$Password=Read-Host “Enter Password” -AsSecureString

new-mailbox -userPrincipalName $upn -alias $alias -name $name  -database “exchange server name\Mailbox Database name”  -OrganizationalUnit ‘yourdomain/your_ou_name’ -Password $Password


The script will ask you to provide a password,Alias,name and UPN (the email address).

How To Print Screen In RDP Session

GPRESULT In Windows Server 2008

Microsoft have made a small change to the Windows Server 2003 GPRESULT command.

In windows 2003 we had to type GPRESULT only in the command line in order to view the Applied Group polices however in windows server 2008 we need to type the /R switch after the gpresult.

The windows Server 2008 the full GPRESULT command is:

gpresult /s

there are other switches to the command which are:

s <Computer> Specifies the name or IP address of a remote computer. Do not use backslashes. The default is the local computer.
/u [<Domain>\]<UserName> Runs the command with the credentials of the specified user. The default user is the user who is logged on to the computer that issues the command.
/p [<Password>] Specifies the password of the user account that is provided in the /u parameter. If /p is omitted, gpresult prompts for the password. /p cannot be used with /x or /h.
/user [<TargetDomain>\]<TargetUser> Specifies the remote user whose RSoP data is to be displayed.
/scope {user | computer} Displays RSoP data for either the user or the computer. If /scope is omitted, gpresult displays RSoP data for both the userand the computer.
[/x | /h] <FileName> Saves the report in either XML (/x) or HTML (/h) format at the location and with the file name specified by the FileName parameter. Cannot be used with /u, /p, /r, /v, or /z.
/f Forces gpresult to overwrite the file name specified in the /x or /h option.
/r Displays RSoP summary data.
/v Displays verbose policy information, including additional detailed settings that have been applied with a precedence of 1.
/z Displays all available information about Group Policy, including detailed settings that have been applied with a precedence of 1 and higher.
/? Displays help at the command prompt.

Limit the Number Of allowed IPSEC VPN sessions on Cisco ASA 5540

To set a limit on the number of allowed IPSEC VPN session on an Cisco ASA 5540 we need to define how many sessions \ users are allowed to be connected to the ASA in each given time.

By default the number of allowed VPN session is unlimited.

To set a limit we need use the Cisco ASDM.

Once logged to the ASDM go to:

Configuration > remote access VPN > Network (client) access > advanced > IPsec > System options

Once there change the maximum IPsec sessions, to the applicable number.

How To Check Which interfaces are Enabled Or Disabled On A Cisco Switch

1. Log on to the router.
2. Type “show interfaces status” command

SWITCH1#sh interfaces status

How To Enable Telnet Access On Cisco ASA 5540

Sometimes there are times that you will need to grant access to other administrators to access the CISCO ASA using telnet.

In Cisco ASA Devices enabling Telnet will not allow all network\hosts to access the ASA using Telnet which will work with Routers and Switches.

In ASA we need to add hosts or networks to the Allowed telnet access list.

First, to view who can access the ASA using telnet type:

ASA# sh run telnet

telnet inside
telnet inside

In this case we have two host that can access the ASA using telnet.

To add an host to the Telnet access list type:

ASA (config)# telnet inside

Hostname or A.B.C.D  The IP address of the host and/or network authorized to

You can also use the ASDM GUI interface by going to:

Configuration > Device Managment > Management Access > Command Line (CLI) >Telnet
