Stream confidentiality error

Question

I have setup my chain as per the online guide (http://www.multichain.com/developers/stream-confidentiality/) lines however i am getting an error when i get about 50% of the way into this guide using this command:

Now we can publish this large chunk of hexadecimal data to the items stream:

multichain-cli ITB-Chain publishfrom 1PD2igfeiK7VyudMeiaR1q41fkV7V64g22qpPf items secret-cpuinfo $cipherhex

Everything has ran smoothly up until this point

 

on server 1:

root@BlockchainMaster-Node1:/# multichain-cli XXX-Chain publishfrom 1PD2igfeiK7VyudMeiaR1q41fkV7V64g22qpPf items secret-cpuinfo $cipherhex
{"method":"publishfrom","params":["1PD2igfeiK7VyudMeiaR1q41fkV7V64g22qpPf","items","secret-cpuinfo"],"id":1,"chain_name":"ITB-Chain"}

Im stuck as everything was going so well up to this point :/

 

Answer 1

These seem to be two different problems. For server 1, looking at the JSON-API request payload, it appears that the $cipherhex shell variable is not being expanded. This could be because you're not running on the bash shell, or because something failed earlier in setting that variable. For server 2, you're trying to publish from an address that doesn't belong to that node. But in any event the tutorial says you should only be running this on the second server, so I'm not sure why you're trying it on the first?
