RIP Configuration on all interfaces

Assume that you have two or more interfaces connected to different networks or subnets on your router ;

Ex.

interface Serial1/1
ip address 10.0.3.5 255.255.255.255
!
interface Serial1/2
ip address 195.167.3.1 255.255.255.252
!
interface Serial1/3
ip address 178.168.2.1 255.255.255.252

You can configure RIP protocol using one network command instead of using network command for each network/subnet.

Using Network command for each subnet/network

router rip
version 2
network 10.0.0.0
network 172.16.0.0
network 192.168.1.0
no auto-summary

RIP confguration using only one network command for all interfaces.
The network configuration command accepts the default network (0.0.0.0) as its parameter, causing RIP Protocol to run on all interfaces on a router.

router rip
version 2
network 0.0.0.0 //You can use only one network command for all interfaces
no auto-summary

To find out the high bandwidth consuming applications being used in your network, you can access the interface connected to the Internet and configure following command

ip nbar protocol-discovery.

This command above enable nbar discovery on your router.

Use following command:-

show ip nbar protocol-discovery stats bit-rate top-n 10

This command above show you top 10 bandwidth consuming applications being used by the users. Now you will be able to block/restrict traffic with appropriate QoS policy.

You can use ip nbar port-map command to look for the protocol or protocol name, using a port number or numbers other than the well-known ports.

Usage as per cisco:-
ip nbar port-map protocol-name [tcp udp] port-number

Up to 16 ports can be specified with this command. Port number values can range from 0 to 65535

SQL Server 2005 Disk Bottleneck & Low CPU Utilization

If CPU utilization is low on your SQL server but response time or run time is high, you might have a disk bottleneck. The Disk Perfmon counters might provide the insight needed for
tuning most of the sequential I/O workloads.
However, in the OLTP workload, the disk load of the log and checkpoint
processes are adjusted by SQL Server. This means the log and checkpoint
processes are invisible to Perfmon.
When writing to the log, the disk queue length is kept at 1. Likewise, the
checkpoint is controlled so that it does not swamp the disk and severely reduce
throughput.

In this case, you can use the query below to capture reads, writes,
and I/O stalls by the database file.

select m.name, v.*, m.physical_name
from sys.dm_io_virtual_file_stats (null, null) v
,sys.master_files m
where v.database_id = m.database_id
and v.file_id = m.file_id

Using this information, you can determine reads/sec, writes/sec, read and write
block sizes, and average number of milliseconds in wait time (I/O stalls) for read
and write operations. If the wait times are large, putting the files in faster disk
arrays can improve database performance.

Number of tasks queued in SQL Server that can be run

The following query shows the number of tasks queued in SQL Server that can be run:

select avg(runnable_tasks_count) from sys.dm_os_schedulers where status = 'VISIBLE ONLINE'

If SQL Server frequently has a non-zero number of runnable tasks, then adding additional processors will likely result in more throughput.

How to Delete a Windows Service in Vista or XP

Instead of disabling a services, you can completely delete the services. This technique can be helpful if the software that you uninstalled, leaves an item in the service list.

You should be very carefull while deleting service , it is very hard to restore the service back. So carefully determine the service that you want to delete.

Deleting a service ;

Open Command Prompt (cmd)

Type:

sc delete ServiceName

If your service name has spaces in it, you should type its name in quotes like this:

Example:

sc delete "Virus Programme"

After completing this step , open Services management console again and you will see that the service is gone.

Problem With Copying Large Files in Windows Vista over Network

2 Mbit E1 line at Center Office, Leased Line and Frame Relay Line at Branch office configuration on Cisco Router 2610

We have a 2 Mbit E1 line on Center Office(Cisco 2610) and on the branch offices we have Leased Lines and Frame Relay line at (Cisco 805 , Cisco 800 ,Cisco 1000) various speeds.

Our Topology as follows ,

Timeslots number :16
Timeslots speed : 64 Kbps

And the configuration is below,

Securing Cisco routers against flaw attack (IOS 12.3 ,12.4)

To find out which version of IOS, you have on your Cisco Router, type the command below in privilege exec mode.

show version

Routers that have the Cisco Unified Communications Manager and voice services enabled can affected by flaw attack. If you are unsure whether your routers have voice services (the SIP protocol) enabled, you should check.

Execute following three commands to see if your router is listening for incoming SIP requests:

show ip sockets

show udp

show tcp brief all

You should look for inbound openings (listeners) for the following protocols and port numbers: TCP 5060, 5061, 1720, 11720 and UDP 5060, 5061, 2427, 2517, 16384 - 32767.

Notice the port number 5060 exists in both cases.

Protecting your Cisco routers from flaw attack.

1) Check to see whether there is an upgrade to the IOS software that contains the bug fix for this vulnerability. It may be hard to upgrade your routers, but this is a good solution. What you should do immediately is either disable the SIP service if it is not needed or perform traffic mitigation to ensure that only legitimate traffic can be sent to and from the affected Cisco routers.

Disable SIP protocol

Router(config)# sip-ua
Router(config-sip-ua)# no transport udp
Router(config-sip-ua)# no transport tcp
Router(config-sip-ua)# end

These commands would disable the SIP protocol and protect you from this vulnerability.
Lastly, if the SIP protocol is needed on your router and if there is no IOS upgrade available, you should go through traffic filtering by authorizing only valid traffic to your affected Cisco IOS devices by creating an access list (ACL) that permits all SIP traffic from known SIP devices on your LAN and denies SIP traffic from all other unknown hosts.
