Windows packet forwarding issue -


my problem is, have simulate on win7 enterprise desktop platform. therefore, have let win7 route/forward data packets (ucast/mcast) coming environ on machine emulated net stack behind tap device.

i have no profound windows background. experienced unixoid-/linxoidist. current project forced interact win7. in context, on win7 platform part of large integration test framework running emigration not fathomable.

problem principle

what did far:

  1. forage half web - there learned interacting win routing , have enable forwarding.
  2. set routing in win7 win netsh -> can list entries netsh show mechanism , acknowledge routes set properly
  3. activate forwarding in hkey registry - windows stack should prepared!
  4. send mcast/ucast packets win stack , prove them arriving -> can trace them pcap (wireshark) - @ disposal of win routing understand
  5. having emulated stack (app) running behind tap device -> tapdev active well
  6. verify arriving packets not forwarded on tapdev -> issue @ "win_routing"

what know:

  • is trying principally possible? mean, win7 desktop prepared such task or have wage several additional micros. packages or have server version?
  • am missing conceptually specific windows? in unix, said principle steps.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
