scaling-computing-machine's Issues

chg_value reg ex

Should format it to atleast do ^ and not allow comparisions to remove any instance where it gets compared.

traceroute operation

traceroute currently does not return anything. only output shows on first hop.

Traceroute needs to start a thread (using join) in main examples/traceroute code. Should print back to standard out.

strptime on only an3 - should have been fixed in last update

problem with wrong device interface getting route assignment

Eth3 does not exist on an2, seems to not get modified correctly when receiving from an3

Traceroute debugging

traceroute needs more debugging code in examples/traceroute.py and anhost/anhost.py to track why why the server killed the request.

Fix route code

Make all gets for linux route tables return Route lists.

Stop route fluctuation

There may be a possibility that routes can fluctuate when a route advertisement stops. One of the neighbors may send out an update after the first route is terminates. This can cause the old route information to re-propagate through the networks.
