Options (19)
| Option | Description | Source |
|---|
-n | Display numeric output, rather than doing a reverse DNS lookup for each hop. | man |
-N | Perform a reverse DNS lookup for each hop, including RFC1918 addresses. | man |
-f | Set the initial TTL used in the first outgoing packet. | man |
-m | Set the maximum TTL used in outgoing packets. | man |
-p | Use the specified local TCP port in outgoing packets. | man |
-s | Set the source address for outgoing packets. | man |
-i | Use the specified interface for outgoing packets. | man |
-q | Set the number of probes to be sent to each hop. | man |
-w | Set the timeout, in seconds, to wait for a response for each probe. | man |
-S | Set the TCP SYN flag in outgoing packets. | man |
-A | Set the TCP ACK flag in outgoing packets. | man |
-E | Send ECN SYN packets, as described in RFC2481. | man |
-t | Set the IP TOS (type of service) to be used in outgoing packets. | man |
-F | Set the IP "don't fragment" bit in outgoing packets. | man |
-l | Set the total packet length to be used in outgoing packets. | man |
-d | Enable debugging, which may or may not be useful. | man |
--dnat | Enable DNAT detection, and display messages when DNAT transitions are observed. | man |
--no-dnat | Enable DNAT detection for the purposes of correctly identifying ICMP time-exceeded messages that match up with outbound probe packets, but do not display messages when a DNAT transition is observed. | man |
--no-dnat-strict | Do not perform any DNAT detection whatsoever. | man |
