Is there a document with the exact description of the syntax of the name of a user defined chain? Searching google on this subject generates a lot of noise. The only thing I can find is an error message by iptables itself: # iptables -N ABCDEFGHIJ12345678901234567890 iptables v1.4.21: chain name `ABCDEFGHIJ12345678901234567890' too long (must be under 29 chars) Ok, 28 chars max, but which chars? I read somewhere on the net that a hyphens are allowed, but underscores are not. However, iptables does not complain when I feed it underscores. Anyone a link to the authoritative doc?
