SLIP is actually working in the following locations:

didn't originally work; by the time sun supplied a patch, I had
already gotten the slipware package (public domain obtained from working. wrote:

I took slip from and run it on my standalone Sun 4/60.
Works great, but of course the shortcomings intrinsic to slip will
soon make me switch to either PPP or cslip. wrote:
One of my co-workers has used SLIP on our SPARCs and on a Sun 4/260.

you can't use the PC/NFS code on a sun -- it's really meant to
be used with PC/NFS.
your best bet is to pick up CSLIP from; i've
installed it in a few places and it works very well wrote:
I'm using SLIP on a Sparc2 running SunOS 4.1.1 with no difficulty. I
don't know about the SLIP that came packaged with the PC-NFS software,
as I am using "slip4.0.tar.Z" which I ftp'd from quite a
while ago. wrote:
We have SLIP running on over 20 Sun4cs around campus. Most of these
are running sun OS 4.1.1 or 4.1. I have not had any problems with it.

If you are going to the
expense of leasing a line you might want to consider purchasing Sunlink
Internetwork Router software. wrote:
I've run SLIP on a Sparc 2 without any troubles. I used a direct
Rs232 null modem cable, not a dialup. The package I used was
slip-4.1-beta.tar.Z The originating location for this is: but there are a number of U.S. sites
that have it, such as uunet. Try archie to locate more.
One caution, some early versions had a typo in slip-attach.c in
line 154. It should say:
if(ioctl(sfd,I+PUSH,"slipen") < 0) {
The type said "slipe" instead. This resulted in a mismatch with
some other code so you got errors that said something like "can't
find slipe connection."

SLIP and vt100tool (and lots of other good and useful stuff) are both on
the '87 Sun User Group tape, which SUG started making available at their
conference in San Jose earlier this month.

Date: Fri, 29 Jun 90 10:07:21 EDT From: We've seen 1.3-1.5Kbps on FTP transfers between SPARCs connected by Trailblazer Plusses using PPP. Interactive traffic is reasonable.

Date: Tue, 9 Oct 90 13:55:23 EDT From: We see very reasonable performance using Telebit Trailblazer Plusses between Suns, but only with more modern stuff than SLIP. Lots of folks use generic V.32 modems, with or without MNP5 data compression. Don't bother with Classic SLIP (RFC1055), which will give poor performance over any connection. At least use header compression (RFC1144), or better yet, avoid SLIP altogether and use PPP (RFC1171).
