Gort looks like a great project!

One issue is that the code appears to only look for data directory in the current working directory, and does not follow the path of the binary.

gort binary is in /usr/bin
data directory is in /usr/bin

$ gort 192.168.1.100
Known ports list under data/port-numbers.xml not found. Trying to download it from https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xml...
Most common open ports list under data/port_open_freq.csv not found. Trying to download it from https://docs.google.com/spreadsheets/d/1r_IriqmkTNPSTiUwii_hQ8Gwl2tfTUz8AGIOIL-wMIE/export?format=csv...

It then creates the data directory and downloads the two files where the command was executed, vs following the path of gort.

Hello,

Thanks for creating this app. I was actually looking for a GOlang's port scanner. Simply because of its excellent performance on threads and accuracy. And the speed is incomparable to other languages.

It would be very useful if you could add these features:

• Add support for ipv4 Ranges. For example:
  123.123.12.23-123.123.16.255

So the command may look like this for IPv4 Ranges:
gort.exe -threads=100 -protocol=tcp -host=123.123.12.23-123.123.12.255 -ports=8080,80,443

• Add function to save the open port results to a file (IP:Port) format.
  For example, the command used:
  gort.exe -threads=100 -protocol=tcp -host=123.123.12.23-123.123.12.255 -ports=8080,80,443 -output=result.txt
  if the open ports found from IPs they will be saved as IP:Port format. If multiple open ports found from same IP, then they will be added in new line like this:
  123.123.12.132:80
  123.123.12.132:8080

• Have option to select scan method. SYN Scan as default is most preferable.

• a custom -timeout= option

Hope you could add this features. There are lots of other port scanners from different languages, but rarely on golang. These features will surely bring this go app to the top.

Best Regards
