I have a testbed with several nodes with different OSs working well with ibr-dtn version 12. However when I tried to use BAB authentication with a plaintext key, the nodes with openwrt do not work well and the destination node print the following message: “WARNING TCPConnection: bundle has been rejected: security checks failed” . I use the same configuration for all nodes and the same key, why is it having security problems.? Do you have any hint ?

config 'daemon' 'security'                                                      

        option level            1                                               

        option bab_key          /root/key.mac                                   

        option key_path         /root 

security_level = 1

security_bab_default_key = /Users/myname/key.mac

security_path = /Users/myname
