Hi guys,
Initially i had thought that amanda was failing to backup one of my
clients w/out an error, but i was wrong. in all of the
/tmp/amandad*000.debug files there is i have this output:
Amanda 2.4 REQ HANDLE 000-C0900608 SEQ 1118089786
SECURITY USER amanda
SERVICE noop
OPTIONS features=fffffeff9ffe0f;
--------
sending nack:
----
Amanda 2.4 NAK HANDLE 000-C0900608 SEQ 1118089786
ERROR unknown service: noop
what is noop?
The "noop" is "no operation".
It was introduced in amanda 2.4.2 I believe. In the same release,
there was also an enhancement that makes it possible to have a
mix of different amanda-client and server versions.
A client and server first exchange a bitmask of "features", and
in the next exchange, limit themselves to the common features only.
The first exchange therefore is not a command, but a "noop", just
exchanging the features of each implementation;
Before that release even "noop" did not exist, and an old
client would answer with a "NAK" (negative ack) of of "ACK". The
fact that a client answers with "NAK" to a "noop" request, informs
the server also of the base list-of-features that that client has.
So the exchange is above is normal and indicating the client is
an older (2.4.1 or earlier) version. The server will notice this
and do not ask for newer features (e.g. include patterns).
