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)
The output is similar to:
Look at the
#os #linux #windows #ping #ttl #iranhost
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
