Hi,

when doing a nncp-exec, the target program at the receiver side is run with environments like 

echo My message |
   NNCP_SELF=REMOTE \
   NNCP_SENDER=OurNodeId \
   NNCP_NICE=123 \
   /usr/sbin/sendmail -t root@localhost

as described on your web page. 

That NNCP_SENDER (and NNCP_SELF) is the hex id of the sender, which in general is rather useless and a long random number. 

Unfortunately, the neighbours are configured in the same file as the secret keys, i.e. /etc/nncp.hjson (if not choosing to write things in a big wood of separate files). So a target programm cannot (and should not be able) to read this and thus cannot determine the label, the human readable name of the sender node. 

Would it be possible to pass the short names, that label used as a key in the neigh-Hash, as additional variables?

regards
