| 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. |
