[BlueOnyx:09491] Re: unable to set numeric sub domain name

According to RFC-952 the first character of a host- or domain-name may not be 
a number, dash or hyphen. It must be a letter. 

See: http://tools.ietf.org/html/rfc952

Hence BlueOnyx doesn't allow a naming convention where a host- or domain-name 
starts with a number.

However, in recent years domain name registries have allowed certain RFC 
violating domain names (9gag.com anyone? ;-), so this RFC may have been 
overtaken by events or bad practices somewhere upstream.

You could edit this file:

/usr/sausalito/schemas/basetypes.schema

It has the following regular expressions for "fqdn" (fully qualified domain 
names), hostnames and domain names:

<typedef name="fqdn" type="re"
  data="^([A-Za-z0-9][A-Za-z0-9\-]*\\.)+[A-Za-z]+$"
/>
        
<typedef name="hostname"        type="re"
  data="^[A-Za-z0-9][A-Za-z0-9\-]*(\\.[A-Za-z0-9][A-Za-z0-9\-]*)*$"
/>

<typedef name="domainname"      type="re"
  data="^[A-Za-z0-9][A-Za-z0-9\-]*([\\.][A-Za-z0-9][A-Za-z0-9\-]*)*$"
/>

After modifying the regular expressions to your liking, restart CCEd for the 
change to take effect:

/etc/init.d/cced.init restart
