network problems
I am having problems with networking on my AXPpci33. I am concentrating
on getting PPP to work as this is my only possible connection to the
internet from that machine, and it is difficult to participate in Debian
development without IP connectivity. When I get this working I will try
ethernet.
installed software:
kernel 2.0.30
- originally from Redhat, supposedly has PPP support built in
base1_3.tgz (August 8)
- from Pasi's site
netbase_2.17-1
netstd_2.16-1
ppp_2.2.0f-24
minicom_1.75-2
- all from the regular sites
First problem: on bootup, not even the loopback interface works (ie
"ping localhost" reports "no route to host"). ifconfig and route show
NOTHING. When I set these up manually, "ping localhost" works.
/etc/init.d/network does not exist. (This is bad, right?) What package
is this file supposed to come from? Isn't this where the loopback
interface should be configured? "ps -ef" does not show inetd. Should it?
If ping works, does that mean that inetd is running?
Next problem: PPP. I can dial in to the PPP server with minicom. Shell
login works fine, so I presume that the serial port and modem (33.6
kbps) are configured properly. (One glitch: the AXPpci33 serial ports
emulate 16550A and are supposed to run at up to 57.6 kbps. However,
using an oscilloscope, I found that they work at 38.4 kbps, but minicom
will not configure them for 57.6; they stay at whatever the last setting
was. Has anyone else seen this? Is this a problem with hardware, the
kernel, or minicom?)
I set up /etc/hosts, /etc/resolv.conf, /etc/host.conf and the PPP
options file according to the instructions in PPP-Howto. I dialed in to
the PPP server with minicom (text mode authentication, no CHAP/PAP) and
started PPP. I then exit minicom without breaking the modem connection
and manually start pppd. Looking at /var/log/messages, it appears that
pppd connects, because the local and remote IP addresses are assigned.
However, route and ifconfig still show nothing, and any attempt to reach
machines on the other end of the connection results in "no route to
host", naturally enough. (Actually, this may have been in
/var/log/messages, I don't remember.)
I have successfully connected to the same PPP server with an Intel
machine running Debian 1.2 . Recent comments on this mailing list
indicate that there may be something wrong with the current Alpha
version of PPP. Am I doing something wrong, or should I just wait for
somebody to fix PPP? (It's outside my area of expertise, unfortunately.)
Am I missing some network-related packages? Why isn't anything
configured at bootup?
[ Chris - let me know what I can do to help fix the unaligned trap
problem in fdisk - I haven't done anything about it yet because of the
sorry state of my internet connectivity. By the way, netstat has the
same problem. ]
