Scott Kuhl 68c9c9bbcd Improve consistency of PATH, environments, and which() ... This patch attempts to fix (or aid in debugging) issue #350. sshuttle didn't explicitly search /sbin and /usr/sbin and they may be missing in the user's PATH. If PATH is missing, these folders wouldn't be searched either. There was also a program_exists function which is redundant to which(). This consolidates everything into the helpers.py file. This patch introduces get_path() to return PATH + some extra hardcoded paths. A new get_env() function can be called to create a consistent environment when calling external programs. The new which() wrapper function also ensures we use the same set of paths. If -vv is supplied, messages clearly indicate the programs we are looking for, if they are found, and where we looked if we failed to find them. I haven't tested the changes to ipfw or pf.		2020-10-23 20:33:20 -04:00
