BIND 4.9.3 shared library resolver SunOS specific details---------------------------------------------------------First off you should ensure the "Shlib Custom" package has been properlyinstalled.  It populates the directory /usr/lib/shlib.etc with files,the most important of which are libc_pic.a and libcs5_pic.a.Install the appropriate "jumbo libc patch" for your SunOS version, ifyou haven't already.  Among other things, this includes fixes for somebugs in the shared library building process.  This will also include theshared library build directory (/usr/lib/shlib.etc), which is useful ifthe "Shlib Custom" package was not already installed.At the time of this writing, the patch numbers and latest revisions ofthe "international" versions of these patches were:    4.1.3:    100891-12    4.1.3_U1: 101558-06    4.1.4:    102545-02Note that "international" means "has not installed the extra-cost 'USEncryption Kit'", so most sites, even in the US, will need theseversions.  If you have installed the "US Encryption Kit" you will needto get the domestic versions.As "recommended" patches, these patches are available for anonymous ftpto all Sun customers, even those without support contracts, fromsunsolve1.sun.com in the /pub/patches directory.Note: apparently the 4.1.4 jumbo libc patch is not "recommended" and istherefore only available with a support contract.  That's the bad news.The good news is that the README claims it only fixes two bugs, and oneof them is in gethostbyname()--which this installation process replaces.The other fix has something to do with NFS over slower links.  Thefixes, as described in the patch README are:1190985 --> gethostbyname() can trash an existing open file descriptor.1197137 --> NFS server crashed w/ "Panic: Bad Trap" when NFS client do a"find" over T1 linkSo, if you have support, it's probably a good idea to install thepatched libc first in any case.SunOS-4.1.1 for sun3 doesn't have an explicit known libc patch, thoughupgrading to 4.1.1_U1 does replace the shared libraries, and it's highlyrecommended that you do this upgrade if at all possible.#ident	   "@(#)bind/shres/netbsd:$Name: rel-821 $:$Id: README.SunOS,v 8.1 1995/12/22 21:57:03 vixie Exp $"
