This was fixed in the project these utils are based on (psutil) and I'm adopting the fix... https://code.google.com/p/psutil/issues/detail?id=201 https://trac.torproject.org/projects/tor/ticket/4777 This evidently occures on OpenWRT (ar71xx), thanks to swalker for the catch! --- src/util/procTools.py | 10 +++++++++- 1 files changed, 9 insertions(+), 1 deletions(-) diff --git a/src/util/procTools.py b/src/util/procTools.py index a592989..39b5407 100644 --- a/src/util/procTools.py +++ b/src/util/procTools.py @@ -288,7 +288,15 @@ def _decodeProcAddressEncoding(addr): # The IPv4 address portion is a little-endian four-byte hexadecimal number. # That is, the least significant byte is listed first, so we need to reverse # the order of the bytes to convert it to an IP address. - ip = socket.inet_ntop(socket.AF_INET, base64.b16decode(ip)[::-1]) + # + # This needs to account for the endian ordering as per... + # http://code.google.com/p/psutil/issues/detail?id=201 + # https://trac.torproject.org/projects/tor/ticket/4777 + + if sys.byteorder == 'little': + ip = socket.inet_ntop(socket.AF_INET, base64.b16decode(ip)[::-1]) + else: + ip = socket.inet_ntop(socket.AF_INET, base64.b16decode(ip)) return (ip, port)
