Hello Tiago.

I have tested several scenarios with BAB authenticated bundles and can not confirm your issues. Are you sure that the BAB key is equal on all hosts? You can do a md5sum on /root/key.mac to compare the keys.

What do you mean with "the nodes with openwrt do not work well"?

Kind regards, Johannes

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 ?

OpenWrt: config 'daemon' 'security'

    option level            1                                       

    option bab_key          /root/key.mac                           

    option key_path         /root 

macbook, ubuntu:

security_level = 1 security_bab_default_key = /Users/myname/key.mac security_path = /Users/myname
