Quite boring, really. Have faffed about with computers since the mid-80s, have worked as a network engineer, unix sysadmin and (occasionally) developer.

comment Network Setup Trouble, getting “unreachable” when trying to respond to external ping
joeqwerty: In general, packets leave from whatever interface is closest to the destination, as determined by the routing table. There is no guarantee that the network path from A to B is the same as the one from B to A (essentially, there is no guarantee that there is symmetric routing in the network). However, odd things can happen when you have asymmetric routing.

comment Should network hardware be set to “autonegotiate” speeds or fixed speeds?
I have seen problems with auto-negotiation between Cisco devices in the past, but that was fast ethernet, rather than gig. No long-haul, typical cable run was 10-25 metres, using Cat5, between two rack rows in a single data centre. Typically between a 7200-series router, using a PA-FE and a 2924 or 2948 switch.

comment ^C no longer sends SIGINT
Is the terminal set to "brkint" or "-brkint"? Similarly for "-ignbrk" and "ignbrk"?

comment Network simulator tool
If you want to experiment with Cisco devices (and have access to one or more IOS images), there's always DynaMIPS and DynaGen (the latter can be found at dynagen.org ).
