How do you know if a remote web server is Linux based or Windows based? (Ignore this if there is pfsense/ha proxy in front)

ping the remote ip:

ping iranhost.com

The output is similar to:

PING iranhost.com (174.142.214.47): 56 data bytes
 64 bytes from 174.142.214.47: icmp_seq=0 ttl=105 time=174.379 ms
 64 bytes from 174.142.214.47: icmp_seq=1 ttl=105 time=180.315 ms
 64 bytes from 174.142.214.47: icmp_seq=2 ttl=105 time=177.937 ms

Look at the ttl part of the output. If it's above 100, it is a windows based machine otherwise it is a Linux based machine.


#os #linux #windows #ping #ttl #iranhost

os.Rename in goLang?

Function signature:

func Rename(oldpath, newpath string) error

What Rename does?

Rename renames (moves) oldpath to newpath. If newpath already exists and is not a directory, Rename replaces it. OS-specific restrictions may apply when oldpath and newpath are in different directories. If there is an error, it will be of type *LinkError.
