I was able to establish a point-to-point SLIP connection between a macIIfx running /etc/slip under A/UX 2.0.1 and a macII running the dirt.cisco.com NSCA telnet version supporting SLIP,this under MacOS 6.0.5. I can open multiple sessions. The problem I have, is that I cannot establish network connections using the macIIfx as a gateway. Is this a bug in A/UX /etc/slip or in NSCA telnet with SLIP or simply a limitation of SLIP itself ? -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | Louis Lamarche, IREQ | lamarche@ireq.hydro.qc.ca | CP 1000, Varennes | or | QC, Canada, J3X 1S1 | 514-652-8077 (office) 514-324-2919 (home)

Is this a bug in A/UX /etc/slip or in >NSCA telnet with SLIP or simply a limitation of SLIP itself ? This definitely belongs in the FAQ list. In A/UX 2.0.1 "ipforwarding" was turned off due to a comment in some RFC that basically states that a host should not abitrarily become a gateway. You can turn ipforwarding back on by issuing the following in adb: # adb -w /unix a.out file = /unix (COFF format) cannot open core ready ipforwarding?D ipforwarding: 0 ipforwarding?W 1 ipforwarding: 0x0 = 0x1 $w $q # Then reboot your Mac so that the change will take effect. You might also want to make the same change to /etc/install.d/boot.d/bnet_dr in case you build a new kernel via newconfig at some later date. -- Ron Flax ron@afsg.apple.com Apple Federal Systems Group

If you'd rather not reboot, do
# adb -k -w /unix /dev/kmem
ipforwarding/W 1
^-- note the slash
This changes the running kernel without affecting what'll happen after the
next boot. You can do both changes in one session. The "-k" flag is
recommended when working on standalone programs such as the kernel (that's
why it's named "-k").
NB: /bin/adb isn't /bin/ed. Writes are performed as soon as you give the /w
or ?w command, and the "$w" above does something entirely different.
"man adb" for details. (You did install the manuals, right? ;-)
