So opening this back up, I don’t think it’s IPv6 related at all.
I have disabled ipv6 for the director and storage. I have confirmed they are
not listening using netstat I also removed the AAAA DNS record for the server.
Clients using configs like:
Client {
Name = sue-hp-touch-fd
FDport = 9102
Address = 192.168.10.6
#Address = 192.168.67.21
Catalog = myth_catalog
Password = “<snip>"
Connection From Client To Director = yes
Heartbeat Interval = 60
}
setdebug level=1000 trace=1 dir
I’m getting errors like:
myth-dir (500): lib/crypto_openssl.cc:1544-0 SSL_get_error() returned want-read
myth-dir (500): lib/crypto_openssl.cc:1544-0 SSL_get_error() returned want-read
myth-dir (500): lib/crypto_openssl.cc:1544-0 SSL_get_error() returned want-read
myth-dir (800): dird/job.cc:732-0 JobMonitorWatchdog 0x565b9f0369e0 called
When I do
status client=<client>
For clients that use client initiated connection. Ironically their jobs still
run, but status fails and just hangs, and I have to break out of bconsole using
Ctl+C
I have been using this for years I have tried giving the client a valid IP on
the local network (even though that’s not the hots address) and random
addreses. Behavior is the same.
Machines that don’t use this or are on the same local LAN work fine. It’s only
the road warriors. It’s more annoying but I don’t htink it’s expected behavior.
Details:
*status client=sue-hp-touch-fd
Connecting to Client sue-hp-touch-fd at 192.168.10.6:9102
Probing client protocol... (result will be saved until config reload)
