OK, found it myself. The answer is /proc/sys/net/ipv4/conf/*/rp_filter. The option is documented at the Linux Foundation. While this is an old setting, it seems that Ubuntu changed the default value sometime between 07.04 and 14.04. Changing the value from 1 back to 0 fixed my problem.
Do not know of a direct way with htop However you might be able to use the negating abilities of pgrep and feed a pid list to htop Something like htop -p "$(pgrep -vfd, 'java|python')" This has the obvious disadvantage of not accounting for processes that start after htop starts running
