Patch Installation Instructions: 

--------------------------------
 
For Solaris 2.0-2.6 releases, refer to the Install.info file and/or
the README within the patch for instructions on using the generic
'installpatch' and 'backoutpatch' scripts provided with each patch.
 
For Solaris 7-10 releases, refer to the man pages for instructions
on using 'patchadd' and 'patchrm' scripts provided with Solaris.
Any other special or non-generic installation instructions should be
described below as special instructions.  The following example
installs a patch to a standalone machine:
 
       example# patchadd /var/spool/patch/104945-02
 
The following example removes a patch from a standalone system:
 
       example# patchrm 104945-02
 
For additional examples please see the appropriate man pages.

Special Install Instructions: 

-----------------------------
 
This patch alters the way the ftp daemon performs name resolution. It now
uses the nsswitch.conf(4) interface instead of using the resolver directly.
This change affects the following:
 
dns resolveroptions
 
This setting was an optional (not included by default) parameter which could be
specified in the /etc/ftpd/ftpaccess(4) file to modify the resolver behavior.
This was done by adding or removing bits in _res.options e.g.
 
dns resolveroptions +aaonly -dnsrch
 
Turns on the aaonly option (only  accept  authoritative answers) and turns
off the dnsrch option (search the domain path).
 
The changes in the ftp daemon no longer use _res.options so the way parameters
are specified changes to be in concordance with that documented in
/etc/resolv.conf(4) e.g.
 
dns resolveroptions rotate attempts:1
 
Turns on querying name servers round-robin and selects querying each name
server only once. This also improves consistency by making the way resolver
options are specified in /etc/ftpd/ftpaccess consistent with /etc/resolv.conf.
 
Installations using resolveroptions in /etc/ftpd/ftpaccess will need to remap
their existing parameters into the style specified in resolv.conf(4).
