Thanks to those who responded to my problem with CSLIP on a Sun SS5
running SunOS 4.1.3_U1. My question was:

---------- Forwarded message ----------

I am having a very difficult time trying to get cslip to work on my Sun SS5.
(I am using the version currently on the math.berkeley.edu FTP site.)

Pertinent information: I am using a Sun SS5 with SunOS 4.1.3_U1. I am using
a Hayes modem but am having no trouble communicating with the modem (i.e.
regular tip dialout works). I do not have Ethernet connected to my system,
just the modem through Serial Port A. I have created /dev/cua0 as specified
in the cslip instructions. I have installed the cslip loadable kernel module
for sun4m. I have modified the cslip login script to suit the SLIP terminal
server I dial into.

My problem: I run on_all_times as root (after modifying the /etc/remote,
/etc/phones, slip.hosts, slip.login, and slip.logout files appropriately for
my site) and get "login failed: exit status 2 from /etc/slip.login"

Then I decided to try the commands by hand. First I did

ifconfig sl0 my_ip_address terminal_server_ip_address netmask correct_netmask

but I get

ifconfig: ioctl (SIOCSIFADDR): Invalid argument

[more material was here, but deleted]

The problem seems to be that I had hacked the slip.login script to bits,
without understanding well enough what was going on in it.

In the process of investigating this problem, I discovered that I was
using an outdated version of cslip (2.6 instead of 2.7). So I took cslip
2.7 from ee.lbl.gov and was pleasantly surprised that it came with
excellent documentation, unlike the 2.6 docs which was sparse and had
typos (only the specific version I took; this comment does not
necessarily apply to all versions of 2.6 on the net.). I followed the 2.7
instructions, didn't hack any files, and it worked on the first try.

Thanks to those who responded.
