Subject: Controlling PPP with crontab - HELP
Date: Tue, 26 Jan 1999 16:32:02 GMT
A quick question:
I have a PPP connection which is controlled from a crontab entry to bring the
link up at 7:30 am and bring it down at 7:30 pm, Mon.-Fri.
I'm using usernetctl to bring the link up and down.
Here's my crontab entries:
SHELL=/bin/sh
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
# Bring up ppp0 7:30 am weekdays
30 07 * * 1-5 root /usr/sbin/usernetctl ppp0 up
35 07 * * 1-5 root /usr/bin/fetchmail -v -a -d 300 -t 60
# Bring down ppp0 7:30 pm weekdays
30 19 * * 1-5 root /usr/sbin/usernetctl ppp0 down
29 19 * * 1-5 root /usr/bin/fetchmail --quit
The PPP link seems to work fine. The only thing I don't understand about it is
if I do a "ps -aux", I see that the CROND job that started PPP won't go away.
Why won't it die/finish? Should I not use usernetctl from a crontab to control
the PPP Link? Any better suggestions? Should I just live with it since it
doesn't affect anything? Why ask why? :-)
Here's my "ps -aux" output:
<blah, blah, blah...> root 2830 0.0 1.5 852 464 ? S 07:30 0:00 CROND
root 2851 0.0 2.1 1212 676 ? S 07:30 0:00 sh /etc/sysconfig/net root
2858 0.0 2.0 1132 624 ? S 07:30 0:00 /usr/sbin/pppd -detac ...
Thanks to everybody in advance,

Hey all,
I'm running Red Hat 5.2 kernels 2.0.34 and
2.0.36 wich works with my ISA NE2000 compatible
net card. I went to get the new 2.2.0-final
kernel, compiled it with the NE2000 driver, and
when I booted it up, I had no network! All my
config files were the same, but my network is
unreachable.
What's the difference between the new drivers and
the old? What am I doing wrong?

Your ISP may be using chap or a scripted login. I would try the later.
Check that your
chat script has a repsone for login: and password: . Actually they normally
set it up to
respond to 'ogin:' and 'sword:' to allow for some dropped characters when
the connection is
first comming up and also to avoid having to deal with capitol letters. All
of this stuff should
be accessable from the 'control-panel' if you are in X-windows as root.

Your log file should be in /var/logs and the file to read should be named
messages.
Since this log is appended by whatever decides to log to it you can use the
tail command
to read the most recent lines (you can read about this in the man pages as
there are options
to change the default number of lines displayed and such).

You don't need that. You can use any two modems and enable line balanceing
in the kernel and do it that way.

I don't think that you can logon as root from anywhere other than the
console...I think you'd have to logon as a different user with superuser
privileges.

Subject: How to compile with SOCK_PACKET support?
Date: Tue, 26 Jan 1999 17:24:24 -0500
I'm trying my first kernel recompile (third day of using linux). This is
with RH5.2, I ran xconfig and went through all the options, but I saw
nothing on SOCK_PACKET support. I'm supposed to add SOCK_PACKET to use
dhcpcd-1.3.17, so I can use my cablemodem (hopefully).
I took a look at the generated makefile (that is what xconfig does, right?),
but saw nothing related to SOCK_PACKET. In fact, I've never been able to
find anything to read about it.
Help, I'm waiting for someone to lend a tip before starting this compile...

As for mail clients etc - the other thing to think about is how do you
want to do it. What you could do is run your own (sendmail/whatever)
mail server, and the client of your choice.
I would hope their server is internet-capable (can it send mail
externally to the internet?) in which case sendmail can forward mail to
it for onward transmission, and you could use fetchmail to log in and
download mail onto your system for you to access however you choose.

Netcom and Earthlink both have webpages in thier support areas that address this.
They also have tech support folks that seem to know what they are doing but it may
take awhile to talk to them (you always have to go thru the guy who checks to see

Subject: Funky ipfwadm/sendmail interaction
Date: Tue, 26 Jan 1999 23:27:30 GMT
Hi folk
I have a problem with a system that sends mail from a machine that uses
ipfwadm to filter packets. The symptom is that mail to newer sendmail
instances fails to go through, because the "sendmail can't write" a
particular welcome line. I can manually simulate the SMTP conversation
over a telnet connection from my machine but real mail won't budge.
I used tcpdump to sniff packets coming to and from the machine. Here's
what I saw.
As soon as my machine connects to the remote SMTP server I see the SYN
packets being exchanged. Then I see a packet from a high port on the
remote server to the auth port on my machine. Then I see an ICMP packet
from my machine to the remote machine that says "tcp post auth
unreachable". If I do the same exercise on a different machine I don't
see the ICMP packet.
What's potting? Any ideas? If anyone wants I could send a full packet
dump of that conversation and a similar dump of the same conversation on
a different machine that works without a hitch.

Subject: ether express 16 and 2.2.0
Date: Tue, 26 Jan 1999 23:36:25 GMT
I'm having some *weird* problems with the new kernel (2.2.0) and my ether
express 16 (which worked flawlessly under 2.0.36).
I upgraded all packages per the README, and I'm currently running net-tools
1.49. I've rebuilt the kernel with various net options (always with IP Masq
enabled--I need it).
Under the new kernel, the eth0 device is initialized and is able to ping with
small amounts of data.
For example, "ping -c 1 -s 32708 172.16.1.101" will send one packet of size
32708 to another machine on the local net. It works fine.
However, "ping -c 1 -s 32709 172.16.1.101" fails. Just one byte over 32,708.
This threshold of packet size moves to 49,092 sometimes, but always is there.
Needless to say, ftp, telnet, http, etc do no work at all.
Trying the above pings on localhost result in the same problem.
The same behavior exists on the ppp0 device, when it's connected. I don't have
anything set in IPChains.
My routing table has the 172.16.0.0/255.255.0.0 network listed TWICE, and I
can't find where or why it does this. If I try to delete the route it returns
a "process not found" error.
Has anyone encountered this problem before? Is it just a result of my routing
table's double-entry? Is there a newer, less stable ether express driver in
the newer kernel?
Any help would be appreciated!

I find the bug in pppd 2.3.5. You must correct 2 strings in
ppp-2.3.5/pppd/ipxcp.c.
1) Near line 149 correct from:
if (internal & IPX_NONE)
external = IPX_NONE;
To:
if (internal & BIT(IPX_NONE))
external = IPX_NONE;
2)Near line 514, from:
#define ACKCIPROTO(opt, neg, val) \
if (neg) { \
To:
#define ACKCIPROTO(opt, neg, val) \
if (neg && (len>0)) { \
Then in directory ppp-2.3.5:
configure
