Hello list,
Installation of the CA-unicenter agents used to monitor my servers
fails if
HOSTNAME is set to FQDN in /etc/sysconfig/network.
This is due to a limitation in CA. According to the CA-documentation the
_I_ would start by bugging CA, citing the relevant RFC (which allows
much longer host names, as I recall).
"Host software MUST handle host names of up to 63 characters and SHOULD
handle host names of up to 255 characters."
http://www.apps.ietf.org/rfc/rfc1123.html#sec-2.1
The DNS itself places only one restriction on the particular labels that
can be used to identify resource records. That one restriction relates
to the length of the label and the full name. The length of any one
label is limited to between 1 and 63 octets. A full domain name is
limited to 255 octets (including the separators).
http://www.apps.ietf.org/rfc/rfc2181.html#sec-11
A simple host name is a label.
Lengths referred to are "on the wire." In transmission, each label is
preceded by a length byte:
02 6a 73 02 69 64 02 61 75 00
for js.id.au
The final NUL signifies the end of the name.
