HELP! I'm running Ultrix 2.0 (binary only :-( ) on a Microvax. I'm trying to install SLIP on this system, with a few slight modifications for Ultrix. When I try to run slattach, I get the message: /dev/ttyxx: No such device or address The mods I've made are as follows: - changed SLIPDISC to 7 in ioctl.h, as Ultrix has 0-6 already defined. - changed tty_conf_data.c to define discipline 6 as nodev,nodev,... (for SYSVDISC - it was defined in ioctl.h, but not set up in tty_conf_data.c), and added the entries for slip after this. - changed if_sl.c to define BSD4_3, and to define MCLALLOC, MCLGET, and MCLFREE (the Ultrix-supplied versions of these don't work with the if_sl code as is, so I had to change one or the other... I chose to change the definitions). - added the necessary entry to /usr/sys/conf/files. - added sl.h to /usr/sys/BINARY.vax That's about it. I don't know whether this version of Ultrix has the kernel routing code fix that was mentioned in the README file for the SLIP distribution, and I (obviously) couldn't install the patches to route.c as we have a binary distribution. The kernel builds fine, if_sl gets compiled and linked in, but I get the above error. Does anyone have any ideas? I understand Ultrix 2.4 (or 3.0) will include SLIP, but I don't want to wait that long. Any help would be appreciated!

I have an associate seeking any information, advise, warnings, etc. regarding the use of SLIP between two Suns over a leased line. He needs the ability to transfer files, remotely login, and send mail. Post or e-mail, as you wish...Thanks in advance.

I used it in both 2400 and 9600 baud. Remote login did not have tolerable response time with the 2400 baud line, and it was ok with 9600. Ftp is pretty good.. If I remember well, the throughput was nearly twice as fast as kermit over the same line. Mail had no problems whatsoever, it worked great. The only complaints I have is that it requires a lot of CPU interrupts to do the job. Sometimes my 'intr' scale of the perfmeter went upto 3200, way over the average of 400 or so. If you are to run slip over 19.2kbaud, I think it's worth it. Anyway, it's worth it, compared to uucp! George Kyriazis kyriazis@turing.cs.rpi.edu kyriazis@rdrc.rpi.edu ------------------------------

I'm sorry to repeat a question, but my mailer had troubles and I know my return address was screwed up in the first message. I'm looking for both documentation on Serial Line IP and a PC implementation. Thanks! R. Murphy (I have read the section in Leffler, McKusick, et al BSD book)
