It shows the client getting a "Write failed: broken pipe" on the socket to the server and the last message on the server being "debug1: SSH2_MSG_KEX_DH_GEX_GROUP sent [preauth]". I suspect the server might be silently crashing in packet.c:packet_write_wait or possibly dh.c:dh_gen_key. These are usually a little tricky to debug. The way I usually start is by sprinkling logit() statements though these functions to see where it gets to. -d _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
