  2. ==========
  3. Wireshark is a free application that allows you to capture and view the data traveling back and forth on your network, providing the ability to drill down and read the contents of each packet – filtered to meet your specific needs. It is commonly utilized to troubleshoot network problems as well as to develop and test software. This open-source protocol analyzer is widely accepted as the industry standard, winning its fair share of awards over the years.

  34. Filters:
  35. ========
  36.  
  37. Filtering on the basis of IP
  38.  
  39. = ip.addr == IPADDRESS
  40.  
  41. For Filtering particular "source"
  42. 1. ip.src == 1.2.3.4
  43.  
  44. For Filtering particular "protocol"
  45. 2. dns
  46.  
  47. Using multiple Filters
  48. 3. dns && ip.src == 1.2.3.4
  49.  
  50. Filtering particular Destination
  51. 4. ip.dst == 1.2.3.4
  52.  
  53. Filtering Multiple Sources (Both Condition should be True)
  54. 5. ip.src == 1.2.3.4 && ip.src == 2.3.4.5
  55.  
  56. Filtering Multiple Sources (Any Condition should be True)
  57. 6. ip.src == 1.2.3.4 || ip.src == 1.2.3.4
  58.  
  59. Either this address in source or destination
  60. 7. ip.addr == 1.2.3.4
  61.  
  62. Not Condition (Dont want to view this source)
  63. 8. !(ip.src == 172.16.3.137)
  64.  
  65. Mutiple filters and both should be true as this is having &&
  66. 9. ip.src == 172.16.3.137 && !(ip.dst == 172.16.3.2)
  67.  
  68. For filtering packets on basis of data it contains
  69. 10. tcp contains vivastreet.co.in
  70.  
  71. For filtering pckets contains password
  72. 11. http.request.method == "POST"
