Command/parameter Description
Ping Ping sends a sequence of 10 ICMP packets to selected host.
Numeric output only Does not resolve host’s IP address to its mnemonic name.
Record route Enables tracking packets’ route.
netcat etcat allows establishing connection with remote host on specified port number.
host host is used to determine if the DNS server correctly resolves mnemonic hostnames.
traceroute traceroute allows for determining packets’ route between Wheel Fudo PAM and the specified host.
Do not resolve hop addresses Subsequent hop IP addresses are not resolved to mnemonic names.
Use ICMP ECHO instead of UDP datagrams Enforces traceroute to use UDP packets instead of ICMP.
Firewall evasion mode Enforces the same port numbers for UDP and TCP packets. Target port is not incremented with each packet sent.
Set the “don’t fragment” bit Disables packet fragmentation in case the packet exceeds defined MTU (Maximum Transmission Unit) value defined for the network. Exceeding the MTU value results in an error.
