NFS klient for DOS: Int. v.0.254: printers, symlinks, and fixes (fwd)

[Michal Brandejs]

> An interim version of Tsoft's nfsdrvr has been posted to
>    ftp.tsoft.net:/pub/tsoft/nfs/pre/nfs0254?.zip   (NEW home site)
>    polyslo.calpoly.edu:/pub/mdurkin/nfs/pre/nfs0254?.zip
a take:
     ftp.fi.muni.cz:/pub/nfs-klient/nfs/pre/...
>
> The WatTCP, Novell LWP, and Trumpet TCPDRV versions are there.
> The MS LanMan TCP version is DELAYED since there are some problems
> that affect only it; as soon as we get them worked out, it will
> be posted as well; it's not forgotten.
>
> This version is intended to get some better testing in the real world
> before it becomes 0.30.  Hopefully 0.30 will be released shortly,
> possibly with another interim release if necessary first, with any
> bugs discovered in this release fixed.  If you try it, you're agreeing
> to be a guinea pig!  Backing up both client and server drives is
> recommended, just in case.
>
> We need FEEDBACK, please!  I'd like to hear from everyone that
> tries this version, whether all good news or otherwise.  Silence
> just makes me wonder if you're finding bugs, getting annoyed, and not
> reporting them :)
>
> Also, I'll take this opportunity to make a suggestion.  If you want
> to achieve the best possible performance with this client, don't assume
> the defaults will deliver it.  In almost all cases you will get better
> performance by increasing the -r/-w and rsize/wsize options with a tradeoff
> in more memory required.  How much you can increase them depends on your
> PC and ethernet card mainly, and somewhat on the server and how busy
> your net is.  Some restrictions for the different stacks...
> Please review the Performance Tuning section of the manual, as well as
> the stack-specific appendixes.  You should be able to achieve at least as
> good, usually from a little to a significant speed advantage over other
> DOS clients.  If you think you've found a system where another DOS client
> performs faster than a tuned Tsoft nfsdrvr (wattcp or lwp), I'd like to
> hear about and investigate it!
>
> As usual, please mail nfs at tsoft.net with bug reports, or if you need
> assistance configuring or performance tuning, etc.
> Or you can phone +1 916 756 4732.
>
> FIXES:
> Reentrancy bug when Windows is run on top.  HIGHLY recommended you
>     use this version if you run Windows; crashes can result with the old bug.
> Various other bugs.
>
> Whatsnew:
>
> Adds support for redirecting printer output to remote printers.
>     both pcnfsd and bwnfsd are supported.
> Adds support for symbolic links, both relative and absolute (latter
>     via auto-mounting, so some restrictions apply).
> Adds a loadhigh option (nfsdrvr -lh) to load nfsdrvr's data segment
>     into high memory (ie, a UMB) leaving more low memory free.
>     The code segment currently stays low but will be lh'able in some
>     future release.
> A root mount is now treated like the owner of all files for purposes of
>     checking writeability in attributes.  This gives root more accurate
>     access to files.
> Added attribs=NoDirRO option; see manual for details.  Workaround for
>     semantic differences between DOS and Unix "read-only" directories.
