[X2Go-Dev] [BUG] Hostname with IPv6 address but no v6 connectivity => SSH connection fail

Hi,

just dumping bugs I found to the ML as a reminder for myself (and as a means of gathering confirmations from other people.)

Prerequisites:

• hostname specified resolves to both an IPv4 and an IPv6 address.
• no connectivity via IPv6, but IPv6 configured network interface (half-broken state)

Symptoms:

• libssh tries to connect via IPv6, but fails
• doesn't even try the IPv4 address (which may just work fine)

Workaround:

• specify IPv4 address as server host

Fix:

• to do
• report to libssh upstream

Best regards,

Mihai
