Description Peter Bieringer 2017-09-20 19:56:44 UTC

Description of problem:
looks like some longer time ago, tnftp lost capability of connecting to link-local addresses using scope identifier


Version-Release number of selected component (if applicable):
tnftp-20141031-1.el7.x86_64


How reproducible:
always

Steps to Reproduce:
/usr/bin/tnftp -v -d fe80::***%eth0


Actual results:
isipv6addr: got 0 for fe80::***%eth0
fetch_ftp: `fe80::***%eth0'
fetch_ftp: user `<null>' pass `<null>' host fe80 port <null> path `:***%eth0' dir `<null>' file `:***%eth0'
tnftp: Can't lookup `fe80:ftp': Name or service not known
tnftp: Can't connect or login to host `fe80:?'


Expected results:
(found an older ftp from Ubuntu LTS 12):
isipv6addr: got 1 for fe80::***%eth0
ftp: Can't connect to `fe80::***%eth0:21': Connection refused
ftp: Can't connect to `fe80::***%eth0:ftp'

Filed bug also here, but don't know whether this is the proper place...
