- UI functionality :
- The UI will have following options.
-
-
-
- 1. Scan Type:
-
- o TCP
- o UDP
- o ICMP
-
- In the current build, only TCP option is implemented.
-
-
-
- 2. Scan Options:
-
- o Ping only
- o Ping and Scan
- o Show Host Responses
-
-
- User can decide to perform only æpingÆ or æping and scanÆ. When user
- selects æPing onlyÆ. All the given hosts will only be pinged to check
- if they are up.
-
- The method used for ping is ICMP echo ping. The hosts will not be scanned
- for open ports and hence option of æShow Host ResponcesÆ will be disabled.
- When user selects æPing and ScanÆ, the option of æShow Host ResponcesÆ is
- enabled. In this option, the application will first perform æpingÆ on the
- given host and then scan the given list of ports.
-
- If æShow Host ResponcesÆ option is checked, then the host responces ( if
- any ) will be displayed to the user for each port being scanned.
-
-
-
- 3. IP Range:

- b. Import Range:
- The user can specify a txt file from
- which the application will pick up the hosts.
