Re: client-ceph [can not connect from client][connect protocol feature mismatch]

[Sonal Dubey <m.sonaldubey@xxxxxxxxx>]

Thanks a lot Stephane and Kamil, 

Your reply was really helpful. I needed a different version of ceph client on my client machine. Initially my java application using librados was throwing connection time out. Then I considered querying ceph from command line (ceph --id ...), which was giving the error -

From the hits given in your mail i tried -

wget -q -O- 'https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc' | sudo apt-key add -
wget -q -O- 'https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/autobuild.asc' | sudo apt-key add -
echo deb http://ceph.com/packages/ceph-extras/debian $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph-extras.list
echo deb http://ceph.com/debian-firefly/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
sudo apt-get install ceph-common

to verify:
ceph --id brts --keyring=/etc/ceph/ceph.client.brts.keyring health
HEALTH_OK

Thanks for the reply.
