This is an URGENT request for help (from any quarters) with KIP routing. We have just started a new term this week, and we are looking to provide full connectivity in the department. The following is a crude diagram of our network topology. Our localtalk is gatwayed by the KFPS-2 onto the Student Subnet. We used to have the FastPath connected onto the Departmental Subnet, and we had CAP5 running fine on a 4.3bsd SUN and a 4.2bsd VAX. The Gould acts as a gateway between the Student Subnet and the Departmental Subnet. Our Macs on the localtalk can telnet to any Unix hosts on the Student Subnet. However, they cannot reach any machines on the Departmental Subnet. CAP no longer runs on any machine on the Departmental Subnet. A copy of the atalkatab file follows the diagram. I have also tried using the atalkrd rebroadcast daemon with no success. I suspect there are flaws in my routing set up. [ VAX ] [ SUN ] | | Departmental Subnet | | (129.31.81) ---------------------------------------------------------------- | | 129.31.81.36 [ GOULD ] 129.31.82.99 | (129.31.82) | Student Subnet ---------------------------------------------------------------- | | 129.31.85.1 [ KFPS-2 ] | | (129.31.85) Localtalk Subnet ---------------------------------------------------------------- atalkatab:- 10.81 N1 129.31.81.0 CSGDOC #DoC Departmental subnet (also tried "10.81 H 129.31.82.99" with atalkrd running on 129.31.82.99) (atalkrd address argument: 129.31.81.255) 10.82 N1 129.31.82.0 CSGDOC #DoC Student subnet 10.85 N1 129.31.85.0 CSGDOC #DoC Localtalk subnet 20.85 KC 129.31.85.1 CSGDOC #Computer room 221 I129.31.85.255 I129.31.82.99 #ipbroad ipname(=Gould) I129.31.82.99 L0 #ipdebug(=Gould) ipfile L0 L0 L0 L0 S0 S0 #ipother unused unused LX0 S0 S31 #flags ipstatic ipdynamic S20.85 S10.85 "CSGDOC" #atneta atnete zonea In the XXX.config file for the FastPath I have set the admin host and the default route (nearest 'real' gateway) to both be 129.31.82.99. Any advice or suggestion will be most welcome. ---- Vincent O.

From article <453@gould.doc.ic.ac.uk>, by voh@doc.ic.ac.uk (Vincent O Ho): - mentions problem with KIP routing. We have almost exactly the same problem with telnet on our Mac's. Here is our current network topology: Vaxen Suns HP9000's | | | | | | Comp-Sci cable 128.100 ----------------------------------------------------------- | | 128.100.11.42 (1st ethernet board) [ENCORE Multimax] 192.9.200.42 (2nd ethernet board) | | Comm-Eng cable 192.9.200 ----------------------------------------------------------- | | | | | | Suns PC's [ Kinetics-Fastpath-3 ] | | | Appletalk cable ----------------------------------------------------------- | | Macs The Mac's in the above diagram can talk to any Sun on the Comm-Eng cable using telnet/ftp/aufs with no problems at all. They cannot however talk to the Encore or anything on the Comp-Sci cable at all. The Comm-Eng Suns have no problems talking to the Encore but they each needed a "route add" to talk properly initially. Likewise on the Comp-Sci cable, their Vaxen and Suns can talk to us ok but a "route add" was needed. Two Sun's are AUFS servers, with one of them being the Kip master for the KFPS: The atalkatab entry for the Kip master Sun (which is on the Comm-Eng cable having 192.9.200.1 as its IP address): ---- 55.200 N1 192.9.200.0 commeng #herman, appletalk-in-IP 56.1 KC appletalk commeng #herman, localtalk I192.9.200.0 I192.9.200.1 #ipbroad ipname I192.9.200.1 L0 #ipdebug ipfile L0 L0 L0 L0 S0 S0 #ipother atnetet unused LX0 S100 S15 #flags ipstatic ipdynamic S56.1 S55.200 #atneta atnete ---- Versions: telnet 2.2 KIP 1/88 CAP 5.0 SunOS 3.5 Vax 4.3bsd (with early '88 tcp/ip from comp.bugs.4bsd.ucb-fixes) Encore UMAX V (unixV31 ax.2.1.b 29JUL88 -- from uname -a) Any help appreciated.
