"Use of uninitialized value $sockargs[11]" and "Connection reset by peer" about imapsync

[gilleslamiral]

Hi Louis,

Can you send me a whole log?

Hi,

by first thanks for this awesome tool! 👍

Since a few days we're getting alot of these errors.
Sometimes it's $sockargs[11] and sometimes it's $sockargs[13] and so on.

We want to migrate quite a big imap-account to Exchange. (Right aroung
10GiB)

Have you seen these errors before?

Thanks for your help!

Greetings,
Louis

Hi Gaurav,

I don't see "Can not open imap connection on [imap.gmail.com]",
no complete log, but it looks like it
http://imapsync.lamiral.info/FAQ.d/FAQ.Gmail.txt

Q. Can not open imap connection on [imap.gmail.com]:
Unable to connect to imap.gmail.com

R0. It looks like this issue is related to ipv6. Both ipv4 and ipv6
protocols should work with gmail and imapsync, I test that regularly,
imapsync works fine for both ipv4 and ipv6.
If you disable ipv6 then disable also ipv6 resolution!
Or at least, make ipv4 answers be taken before ipv6 since the default
names resolution order is to present ipv6 name resolutions first.

R1. A first simple solution is to use directly gmail ipv4 ip address:

imapsync ... --host1 64.233.184.108

In case it changes, get it with any command showing the imap.gmail.com
name resolution, try one of those:

nslookup imap.gmail.com
host imap.gmail.com
ping imap.gmail.com

Or go to http://ping.eu/nslookup/ to get the resolution.

R2. Second solution. Fix imapsync with the line:

use IO::Socket::SSL 'inet4' ;

Thanks to Chris Nolan to report, understand and fix this issue!
