We all know Dynampis the great Cisco IOS emulator, and VMWare the great OS Virtual Machine.we can operate both in order to get a fully equiped network infrastructure. But, that will be very heavy on the host PC resources (CPU and RAM).to connect Virtual PC to Dynamips, we need at first to define Dynamips device to be connected to our physical interface. then connect our virtual PC (vmware) to that physical interface too using either NAT or Bridged connecti...
what an interesting topic to write about :-)rate limiting on a cisco device could be so easy or so hard...examples:on a cisco 4900 series switch (L3 switch) rate limiting is done using QoS, policing or shaping.policing which dealing with excess traffic by dropping it. while shaping is more smooth by putting excess traffic in a buffer for later transmition.configuration:SW#conf tSW()#policy-map SW(-pmap)#class SW(-pmap-c)#shape average | percent or use the following to police:SW(-pmap-c)#police confirm-action exceed-action...
if u r telnetting or doing ssh to a linux server you cant tell the version or its type.some will tell you to use this command:uname -adaaa!! no distr type .so, i recommend to use this:dmesg | head -1or try this one:cat /etc/issueor this same effect command:cat /proc/versioni hope that this was helpfull ...
BGPThis is the EGP (External Gateway Protocol) protocol used for routing the traffic in the internet. The major concept is AS which is Autonomous System number, which is the building block of the internet, BGP routes traffic between these AS (blocks).Running Pure BGP:If BGP is the only routing protocol inside your network, you should define the linking networks between the routers to have full connectivity. Because the absence of IGP (RIP, OSPF,…) will cause that BGP won't know about these networks.Configuration:Begins with...

AES Encryption Standard History: The Advanced Encryption Standard (AES) is an encryption standard adopted by the U.S. government. The standard comprises three block ciphers, AES-128, AES-192 and AES-256, adopted from a larger collection originally published as Rijndael. Each AES cipher has a 128-bit block size, with key sizes of 128, 192 and 256 bits, respectively. The AES ciphers have been analyzed extensively and are now used worldwide, as was the case with its predecessor, the Data Encryption Standard (DES). AES...
easy hardware vpn..its pretty hard to implement secure vpn tunnels using cisco IOS CLI (command line), although cisco introduced the SDM (Security Device Manager). which has a wizard to setup a vpn tunnel, but i think it still needs fine tuning using the CLI.so, i good solution to setup site-to-site vpn tunnels or remote access ones, is to have hardware vpn devices, an affordable one is the liksys RVS4000, RV082 or RV042. which has an eassy to setup vpn capabilitis, ipsec, wan ports which could be PPPoE or static ips. for mobile...
