I searched my log files, but couldn't find a trace of such an error message.
The error message "kxchg: send: .." is generated by ciped (in kxchg(), after
a send(2) returns an error, while sending NK_REQ, NK_ACK or NK_IND).
The error code EPERM "Operation not permitted" is probably orginating from
the ip-layer IP(7): "User doesn't have permission to set high priority,
change configuration, or send signals to the requested process or group."
* It is NOT related to connectionless UDP traffic (send(2) assumes a
* If you are running PKCIPE, see section 4.3 of the manual: "The pkcipe
program must be run as root. (Do not make it setuid.)"....
*** Verify if PKCIPE's TCP (!) connection with the remote PKCIPE is allowed
and not blocked by a firewall!!
* DEBUG: Run PKCIPE with -D debug; Run cipcb in debug mode, or better: run a
debug version (configured without --disable_debug).
My guess is that cipe is working with the static key and that pkcipe is
causing the messages because ciped isn't able to exchange (dynamic) keys.
But it's only a wild guess, based on a minimum of information....
If you are NOT using pkcipe: a minor mismatch between the cipcb module and
your kernel MAY cause this kind of erratic behaviour: the module must have
been built using the same compiler and (identical configured) source tree as
used to build you running kernel.
I hope this is of any help or use.
