[pkg-gnupg-maint] Bug#867268: dirmngr: Can't set nameserver port

[Sandro Knauß]

Package: gnupg2
Version: 2.1.21-2
Severity: normal

Hey,

I'm using gnupg with use-tor option and a onion address as keyserver.
All wents find to search keys over the keyserver and so one. But it
fails, if I try to search at a keyserver with a "normal" dns name like
keyserver.debian.org:

$ gpg --keyserver hkp://keyring.debian.org --recv-key 0x78754D07BC095C7448F78D66058C1CF944F6BD3C
gpg: keyserver receive failed: Invalid textual address form

if I comment in my dirmgr.conf the use-tor. It all works fine:
$ killall dirmngr
$ gpg2 --keyserver hkp://keyring.debian.org --recv-key 0x78754D07BC095C7448F78D66058C1CF944F6BD3C
gpg: key 0xB82A217AFDFE09F2: "David Prévot <david at tilapin.org>" not changed
gpg: Total number processed: 1
gpg:              unchanged: 1

from the dirmngr.log it looks like the problem is my nameserver entry in
dirmgr:
failed to set nameserver '[127.0.0.1:1053]:53': Invalid textual address form
resolving 'keyring.debian.org' failed: Invalid textual address form
can't connect to 'keyring.debian.org': host not found
error connecting to 'http://keyring.debian.org:11371': Invalid textual address form

so it looks like he is unhappy about my nameserver entry in dirmgr.conf:
nameserver 127.0.0.1:1053

it is quite unexpected, that I can't overwrite the port for the nameserver. The nameserver port is the dnsport from tor:
/etc/tor/torrc:

DNSPort 127.0.0.1:1053

and I actually wants to make sure that gnupg is using dns over tor.

Best Regards,

sandro
