Debian's dhcpcd .70-5 deb pkg wasn't working with my Intel eth0
and potato kernel 2.1.125 so I couldn't get a DSL account. Now I'm set,
thanks to Sergei Viznyuk. /etc/dhcpc/ has a file written by dhcpcd
which has my IP and the DNS nameserver assigned by ISP.
To get your IP assigned dynamically as by dial-up or ADSL or
cable modem, and to find out nameserver IP's--it's also necessary
to upgrade dhcpcd for kernels 2.1.125 and up, and for certain
netcards such as Intel--
ftp://phystech.com/pub
get the latest dhcpcd dhcp client by Sergei Viznyuk [applause, cheers]
which today is 1.3.17-pl2
untar ungzip cd
make ; make install
Now you have /sbin/dhcpcd
Get your old dhcpcd out of the way--it was /usr/sbin/dhcpcd
In Debian it seemed logical to load dhcpcd using /etc/init.d/network
script--
most of this varies according to site-- "dhcpcd -h username" wasn't
working
from /etc/init.d/dhcpc script's line using start-stop-daemon, so--
#! /bin/sh
PATH="/bin:/sbin:/usr/bin:/usr/sbin"
ISP_USER_ID=username
ifconfig lo 127.0.0.1
route add -net 127.0.0.0 netmask 255.0.0.0 lo
if dhcpcd -h $ISP_USER_ID -d eth0 ; then
echo -n "DHCP succeeded..."
logger "DHCP succeeded..."
else
echo -n "DHCP failed..."
logger "DHCP failed... "

Subject: How do you run slip/ppp between two machines?
Date: 18 Jan 1999 07:24:06 GMT
I'm trying to install a slip or ppp connection between two RH 5.2 boxes
connected by a short serial cable. On both boxes, dip works fine when
I dial out to a ppp server. Moreover plip works fine between the two
boxes connected by a laplink cable. For hardware reasons however my
application requires a serial line between the boxes.
Normally I would simply run slattach but slattach seems to have
vanished from the redhat world (if it ever was there). I've so far
been unable to get the slattach-1.2.0 distributed with slackware to
compile under RH 5.2, the include files seem to be different and even
after a lot of fiddling with the #include statements in the code I'm
still unable to get it to compile.
So, is there any straightforward way under RH 5.2 of running slip or
ppp across a short cable, short of the highly inelegant solution of
using dip and setting one end up as a general purpose server? By
"straightforward" I mean something as simple as plip or slattach, which
can be configured with a single line of information.
If you have a slattach binary that works under RH 5.2, or slattach
source that compiles under RH 5.2, that would be ideal. Equally good
would be instructions for how to configure pppd for this application:
the voluminous pppd documentation doesn't seem to have anything to say
about this simple case. PPP-HOWTO promises "This document provides a
brief overview of using PPP to link two Linux PCs via a null modem
cable" but whoever wrote that forgot to include the overview.

It would have helped to have your .fetchamilrc posted. Best bet is
to make sure you have sendmail running so fetchmail has someplace
to hand off mail.

Any good reason to do so when redhat comes with exactly that version?
Anyway, start from the package in SRPMS. This will include all the patch
files required to solve your problem.

Subject: SIOCADDRT Invalid argument during boot
Date: Mon, 18 Jan 1999 12:41:12 +1100
I have had this problem (<SIOCADDRT Invalid argument during boot>), and
seen various references to it in newsgroups. Just want to let anyone
who's interested know how I seem to have got rid of it. I am running
Redhat 5.2 on two machines linked via tcpip/ethernet. These machines are
named client and server. After doing a
RedHat-yes-I-want-networking-install, with the default gateway set
blank, getting them to talk with telnet and ftp was relatively easy. The
only problem was <SIOCADDRT Invalid argument during boot>.
From my way of thinking (I'm not a networking person) in this setup
you do not want a default gateway, as these machines do not have packets
floating thru them that are destined for some unknown address. This was
bourne out to be the right way of thinking when I did another install,
letting the RedHat install default in a default gateway IP address - I
couldn't get client to talk to the outside world via PPP - I got the
error message "not replacing existing default route to eth0". However
the SIOCADDRT problem had disappeared. Thus the SIOCADDRT argument that
is wrong 'must' be the default gateway!
There is a file called /etc/sysconfig/network which the install
seems to populate the last two lines of (one line refers to the gateway
address, the other the ethernet card). Now that I was 'sure' I didn't
need a default gateway it occured to me that the SIOCADDRT problem might
be due to the RedHat install putting a default gateway address of
0.0.0.0 into /etc/sysconfig/network when you blank out the field during
the install - SIOCADDRT (whatever it does!) might be croaking on a
0.0.0.0 arguement. To test this I commented out the last two lines of
/etc/sysconfig/network and rebooted. The SIOCADDRT boot problem did not
come back. A few other networking problems I was having also seemed to
disappear:
-> When trying to connect via PPP, with the nameserver addresses
set, I would get this error (/var/log/messages):
<
CCP: timeout sending Config-Requests
Connection terminated
Receive serial link is not 8-bit clean:
Problem: all had bit 7 set to 0
Exit.
>
This error meant that you couldn't browse sites using their
names, only their addresses.
-> When using ftp, this was sent to stderr: <ftp: bind: Address
already in use>
If I could have gone about trying to solve this problem in a
slightly more
efficient way then I would certainly appreciate the advice!

I have seen much discussion over appropriate Ethernet=20

subject to the same concerns of operability with Linux? I am a newbie to =
Linux (and networking in general) and in the materials on the net I have =
reviewed, I have not come across many such questions.
Have I missed an appropriate FAQ or HOWTO on this topic?
For example, if a d-link card is not supported by linux, does the same =
necessarily hold for the hub? Any recommendations on a fast etherlink 4 =
or 5 port hub and concomitant NICs? My primary concern would be ease of =
use by both Windows and Linux systems. Cost will not be the primary =
factor.Similar vendors of both would seem to make facial sense; but is =
this really a concern?.
Any thoughts would be most appreciated.

Yes, it's possible. The two functions are served by two separate
daemons. For outgoing SMTP mail, you would use an SMTP server
such as sendmail and for retrieving email to a client, you would need
a POP server such as popd. There is no issue with transfering mail
between then. When an email arrives at the SMTP server and if it
happens to be the destination SMTP server, the message would be
delivered by the SMTP server (deposited in a file usually). It's left
there until an email retrieval client gets to it, this could be Unix mail
clients such as mail or it would be a POP client.

Hmmmm, I just put in my RH 5.2 cd, booted into the install, used fdisk

I didnt do anything about no DHCP or nothing and I use cox@home thru
Cox Communications here in Omaha. I'll have to say I like OpenLinux
better than RH but just had to try RH 5.2. With OpenLinux, I had to

If I remember correctly pppd always reads the /etc/ppp/options
(there must always be a one) file although the file option is used
to guide the pppd to read another options file. So in your case
callback is enabled always because it is enabled in options file.
Rename options file to something else and configure your script
to use that. If pppd requires (I think it does) /etc/ppp/options -file
you can make there an empty file and pppd is happy again.

Hello all, sorry for the cross-post, but I figured this is relevant to both
newsgroups ?
Err. I've got RedHat 5.2 running on my laptop, with a PCMCIA network card,
and I seem to have a bit of a problem with all the network daemons running on
the box.
I can't seem to telnet into it ?
neither can my colleagues rlogin into it ?
and although I have WU-FTPD RPM installed and I believe it's running, any
connections get *rejected* ???
I have the Portmap RPM installed ... I think that might help ...
It's a Twinhead Slimnote VX running RedHat Linux 5.2 installed from the
official boxed CD. I haven't got a clue as to how to fix it.
Tried poking through /etc/inet.conf and /etc/hosts.*
no help ...
