Subject Remote SSH on Apache with SSH Port Forwading
Date Fri, 24 Aug 2012 10:46:00 GMT
Hi,

Could it be possible that ssh server (MINA) of Karaf cannot work with SSH /
Port Forwarding

Cloud instance = fabric-fuse.rhcloud.com accepting ssh port number 22
Connection initiated from a MacBook Pro and using a dummy port 22000
127.6.51.129 = internal IP address used by Apache Karaf on the cloud
instance
18101 = Karaf SSH port

REMARK : when connected to the machine UUID@fabric-fuse.rhcloud.com, I can
perform locally a ssh localhost -p 18101 -l karaf

MacBook-Pro:fabric chmoulli$ ssh -N -L "22000:127.6.51.129:18101"
UUID@fabric-fuse.rhcloud.com -v

Nothing happens here and no communication is negotiated with ssh server of
karaf
