#2098 fixed Address family not supported by protocol connection error Antoine Martin J. Max Mena
Description

Currently running trunk r21278 on a Fedora 28 server and trying to connect with another trunk r21278 Fedora 28 machine as a client.

Attempting to connect using xpra attach ssh:user@host or xpra attach tcp:ip:port or xpra attach ssh:host (which works for me because my user is the same on the client and server) fails with the following error:

xpra initialization error:
 connection failed: [Errno 97] Address family not supported by protocol

Rolling my server back to r21275 fixes it, and a quick bisection shows that r21276 is where the issue appears for me.

#2097 worksforme SSHFP with paramiko elenril elenril
Description

One feature that I've been using with openssh, but is missing from the new paramiko code, is checking SSHFP DNS records.

Some background: SSHFP records are used to publish a host key fingerprints in DNS, then (assuming the domain is DNSSEC-secured and the client has a validating resolver) the client can verify the host keys through DNS rather than the classic trust-on-first-use method. In openssh, this is enabled by the VerifyHostKeyDNS yes option in ssh_config. Since I have many hosts which connect to each other, I think this scales better than the classic known_hosts approach.

Now, paramiko does not support SSHFP natively, but it can be implemented by the caller through a custom missing host key policy. I'm attaching code for this policy I use in another codebase, though I am not sure whether it belongs in xpra or should be added to paramiko itself, or implemented in some other manner. Thoughts?

#2096 needinfo unicode error with win32 builds Antoine Martin Antoine Martin
Description

With 2.4.?

Stacktrace reported as a picture (..):

xpra/scripts/main.py line 68 in main
xpra/scripts/config.py line 1178 in make_defaults_struct
xpra/scripts/config.py line 389 in read_xpra_defaults
xpra/os_util.py line 486 in osexpand
xpra/os_util.py line 451 in shellsub

My guess, based on the screenshot is that this is a character encoding issue with the username or home path.
