- * It seems that `-l' and `-g' will not work correctly together (IPv6).
-
- Wait for "flow label" API to be appeared in kernel-headers and
- think about it immediately after that... :)
-
-
- * Tune default parameters properly.
-
- Maybe decrease `-w' secs to 4.0 instead of 5.0 (as Network is faster now).
-
-
- * Verbose output. Show method in use, what ports we are connecting to,
- more info about icmp response etc.
-
-
- * The "final hop" issue.
-
- All methods, usable when firewalls are present in the network path,
- normally use some particular destination port. Most often it is a port
- of an already running application.
-
- It requires that the packet sent should be correct for such an application
- (for example, for tracing with udp to port 53, it should be correct DNS
- request), and the application normally should answer something on it.
- (TCP has no such an issue, as there are just syn to, and ack or reset from).
-
- In general, we should fill the packet's data depending on the dest port
- and protocol. It seems not a task for traceroute itself, it could be
- some cmdline option or even external hook...
-
-
- * Think about SCTP and DCCP methods (these protocols are already in kernel).
-
-
- * Think about "multicast tracerouting" (mrouted(8) and other).
- The idea is to increase the room in the mtrace packet step-by-step
- (as well as we increase ttl). It seems that if there is no more space
- in the probe's room, the mrouted(8) daemon answers immediately, the same
- way as if it is a final hop.
-
- For IPv6 mtrace, there is an RFC draft for this already...
-
-
- * Make the output more clean -- use two spaces before any printed address
- (not the first one only), and use two spaces between expired probes as well.
-
-
- * Maybe implement some config file (both user and system-wide),
- with directives (auto)generated from the general-type long-options.
- This could allow people to tune default parameters.
-
- The presence of such files even makes it reasonable to add some more
- long-options (fe. to tune the form of output), as the user can specify
- it in configfile just at once.
