This is the next thing I tried after posting my previous reply.
It was commented, and the man page says it is enable by default.
Anyway, I forced it on yes, restarted sshd and tried again but with no
success.
I'm trying the same operation after increasing the sshd log verbosity.
OK, I'm progressing : the ssh issue seems to be gone.
I changed some parameters but not sure which one are relevant.
When comparing with a fresh install, here are the diffs :
root:/etc# diff /etc/ssh/sshd_config /tmp/sshd_config
43a44
LogLevel DEBUG3
48c49
< #PermitRootLogin yes
---
PermitRootLogin yes
114,115c115,116
< #AllowTcpForwarding yes
< #GatewayPorts no
---
AllowTcpForwarding yes
GatewayPorts yes
The man page specifically says that the -R option won't work unless
GatewayPorts is set to yes, and it is NOT able by default.
But i don't remember if this was sufficient, because I may have change
PermitRootLogin in the same time.
What is sure is that AllowTcpForwading set to yes did not change anything.
Anyway, now, I can see things running for some times. Then failing.
The log file is attached. I have read it quickly. I'm tired. See you
tomorrow.
