Start with the _Linux Electronic Mail HOWTO_
<http://www.ssc.com/linux/LDP/HOWTO/Mail-HOWTO.html>. I would
recommend Qmail, but you could also use Smail or sendmail.

Sure, it's acheivable with any mail/pop server combination.

Yes. You simply set your DNS (or tell your DNS provider to set it up)
so mail is directed to your mail server. In the meantime, if you run
your own mail server, but still need to get mail from your ISP's mail
server, you can use fetchmail to spool that mail to your local server,
so you only have to pop mail from one location.

Ummm... no.
The (P) is a pun. It transforms the ludicrous "operating

Subject: Serial port looped back with pppd and diald at both ends
Date: 20 Apr 1999 14:21:03 GMT
Hello.
I'm trying to set up a pair of Linux 2.2.5 boxes (Debian
distribution) to route traffic between two ethernets over a PPP
link. I have no problem with configuring the routing and the proxy
ARP: once the PPP link is up everything works perfectly. My problem
is getting the link up in the first place, which is very
tempremental.
It must be possible for either end to initiate the connection, so I
am running diald on both ends. I am using the 'diald-login' script
that was in the examples that came with the diald package. I have
created a special account on each machine and set the login shell of
these accounts to the diald-login script. Mgetty is run from initab
to accept logins from the modem. The diald connect scripts are set
up to log into these special accounts.
The puzzling result is that if A initiates the connection normally
everything works perfectly, although on occasion A has reported the
serial port as looped back. This temporary problem was apparently
fixed by rebooting B.
If B trys to initiate the connection, it always gets the serial port
looped back. However, it never reports this. Instead it just sits
there sending and receiving its own ConfReqs and ConfNaks until it
times out. At this stage A has definately started pppd but neither
end seems able to talk to the other.
I also tried setting both ends to use CSLIP instead and got a similar
result, in that if A initiates the connection it works and you can
ping the other end, but if B initiates the connection it and if you
try and ping A from B, you can see the receive light on A's modem
flash but tcpdump doesn't show any received packets on that device.
A is using pppd v 2.3.5 and B is using pppd v 2.3.7, although I
cannot see what difference this makes if I have a similar problem
using CSLIP.
I've checked all config files for consistency in naming the serial
port, and both diald and pppd have the 'lock' option in their config
file.
Can anybody please help me?
Thanks.

My docs at http://cirl.meei.harvard.edu/hylafax/linux/ aren't helpful for the
PPP issues?
X-windows is its own set of issues. Those are often difficult to wade
through, I admit.
In general, I find that a detailed question to the Usenet about an issue
is stunningly more useful than a tech support to Microsoft or their
often collateral-damaged software partners.

And he had a point here. The learning curve for a Windows
administrator plateaus much faster than for a Linux administrator, but
at a vastly lower level. And at least the docs are at least *THERE*,
and you don't have to buy just plain fraudulent source books or add-on
debuggers to decode what the hell happened to somebody's machine. It's
usually still running enough to remotely log in and double check it:
and the concept of a "only the root user can mess with the important
stuff" saves so many man-hours, it's stunning.

Subject: Can't dial out with chat
I'm trying to set up a PPP connection on a RH5.2 installation, but chat
doesn't seem to want to dial out, although I can successfully dial out
manually with minicom. It get the following log messages in
/var/log/messages:
Apr 20 23:45:26 gw pppd[857]: pppd 2.3.5 started by root, uid 0
Apr 20 23:45:26 gw chat[858]: timeout set to 3 seconds

Apr 20 23:45:33 gw chat[858]: Failed
Apr 20 23:45:34 gw pppd[857]: Exit.
Chat never seems to get an 'OK' from the modem within the 3 second
timeout. Actually, it seems to not be reading and writing from
dev/modem at all.
If I try to just get it to dial with:
/usr/sbin/pppd /dev/ttyS1 57600 debug connect "/usr/sbin/chat -v ''
AT OK ATD5555555 CONNECT '\d\c'"
I get the following kinds of messages in the log (tons of 'em):
Apr 21 00:17:30 gw chat[1648]: alarm
Apr 21 00:17:30 gw chat[1648]: Can't restore terminal parameters:
Input/output error
Apr 21 00:17:31 gw last message repeated 1125 times
Anyone seen this behavior before? Any info would be much appreciated.
Thanks,
Dhiren

Are you sure /dev/ttyS1 is the modem device file? The configuration
is done by setserial in a boot-up file in /etc/rc.* The port and IRQ
must match the ones the modem actually uses. You can check on port
and IRQ by doing "setserial /dev/ttyS1" .
Since minicom works, look for the correct device file by looking at the
options, alt-o .

hi there,
i got adsl here in germany last week. now i want the other computers in my

but : i always have to log-on at the proxy/firewall. once the connection is
made, i only have to log-on again when the connection is closed inbetween.
so, how can i tell my linux box to log-on automagically, like with ppp ?

Subject: Ip Aliases - sending packets from aliases?
Date: 21 Apr 1999 09:01:38 GMT
Hi,
The following question relates to IP aliases.
I'm not sure if the groups I've posted to are the correct
place - but I couldn't find a really correct group.
Bear with me if you've any expertise in programming IP Aliases.
If I have the following IP aliases configuration
(IP numbers changed to protect the innocent :-):
eth0 Link encap:Ethernet HWaddr 00:48:54:01:28:61
inet addr:10.0.0.172 Bcast:10.0.0.175 Mask:255.255.255.248
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:921326 errors:0 dropped:0 overruns:0 frame:0
TX packets:92310 errors:4 dropped:0 overruns:0 carrier:10
collisions:8167
Interrupt:10 Base address:0xd000
eth0:1 Link encap:Ethernet HWaddr 00:48:54:01:28:61
inet addr:10.0.0.173 Mask:255.255.255.255
UP RUNNING MTU:1500 Metric:1
RX packets:1 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

eth0:2 Link encap:Ethernet HWaddr 00:48:54:01:28:61
inet addr:10.0.0.174 Mask:255.255.255.255
UP RUNNING MTU:1500 Metric:1
RX packets:2 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0
It's relatively easy to write code that will listen()
on each of these interfaces. I've been going mad trying
to get the "reverse" to work.
Is it possible to write code under Linux that allows outgoing
packets (after a connect(), etc) to come from the aliased
interfaces (eth0:1, etc) rather than simply eth0?
If so; could someone point me at the correct ioctl()
or the socket options or even a snippet of code.
Please remove the "eatspam" from my reply address to
send to me if you reply directly.
thanks,
Geoff

The problem is when a PC client lock a file, Mac client dose not recognize
