Had the same hang. Client is Ubuntu 15.10 and server is 14.04, both up
to date as of today. Fix was to change client MTU from 9000 to 1500.

Has there been any recent updates on this? I have a network setup with
tunnels between Cisco routers as the egress points for each remote site
and am having the same problems when attempting to SSH from a host
inside of one site to the other. Again, MTU related. I hope there is a
permanent fix
Since the DF bit is set and PMTUD is being disobeyed, I discovered that
MSS is obeyed. Therefore, I resolved my problems by doing the overhead
math and setting the MSS adjust parameter on the LAN facing interfaces
of my routers. This workaround is definitely more scalable than
changing the

Problem was reproduced with openSUSE as client (opened pptp VPN to work

It is not the Ubuntu bag:

Hello again, problem appeared on openSUSE 13.2 (x32) as client and Xubuntu
14.04.2 as a server.

Seems like it is a server problem not a client.

I had this same problem today and we changed the MTU to 1500 on the

straight afterwards. I was trying to do a simple git clone

besides setting MTU to 1480, it is wise to do:

Setting the MTU to 1480 did it. This MTU problem also affects navigation

Same problem here. MTU of the server is 1500, changing client MTU to the
same value doesn't fix it.
Testing with ping, 1300 byte pings make it through fine, so tried
setting client MTU to that on both client and server. No dice.
Server version is OpenSSH_5.9p1 Debian-5ubuntu1.4, OpenSSL 1.0.1 14
setting MTU to 1200 fixed my problem

It's almost certanly MTU problem. Just try

The next time I removed the X forwarding ( ssh -X ) and it didn't hang
so X-forwarding (or the attempted access thereof) may play a role in
