Some of these utilities might not work for ttySx devices, but current
versions does. Try an upgraded chat utility. Probably should upgrade
everything to RH5.2 level, as the current chat also requires glibc,
which requires an upgraded ......
The stty command won't return until carrier is present from the modem,
and that is the expected behaviour from most unix versions as well.

Thanks, I will look into your suggestions. I'm running RH 5.1, ppp
was installed, , some addition info, is that there's a timeout, before
the error occurs
The /var/log/messages has the following in it:
11:10:09 lingate pppd[368]: Connect: ppp0 <--> /dev/ttyS2
11:10:39 lingate pppd[368]: LCP: timeout sending Config-Requests
11:10:39 lingate pppd[368]: Connection terminated.
11:10:39 lingate pppd[368]: Receive serial link is not 8-bit clean:

I bet this will tell you exactly what is wrong. As for me it tells me
nothing. I know just enough to be dangerous, but I'm trying to remedy
that.

Klaus,
I've installed the virtual server, and have not been able to get it to work. I
see no error messages, but I cannot reach my IIS box inside the firewall. I
used the following command for port forwarding:
ippfvsadm -A -t 24.130.79.29:80 -R 192.168.1.1:80
When I hit my website at 25.130.70.29 nothing happens unless I have httpd
running on my linux box, which is what I don't really want to do. I'm using
RH Linux 5.1 with the 2.0.36 kernel. So far nothing that I've tried as
successfully routed my http requests to my internal IIS 4 box. I've tried the
following:
rinetd, ipautofw, ipportfw, and now the Virtual Server program. Does anyone
have any thoughts about how I should go about systematically testing to see
where the failure lies. As you can see I'm pretty new at setting up web
servers and routing http packets.
Thanks in advance, Derek

ya..the built in firewall works pretty good
just select firewalling in the make menuconfig(or xconfig)

I was expecting a fast result. I have heard great things about linux newsgroups.
At least when I post to a Microsoft newsgroup I get a timely helpfull response.
I don't see how the linux community can even pretend to challenge Microsoft when they
aren't even willing to make suggestions to their fellow linux users. Microsoft (who
aren't renowned for their tech support) are generally more helpful.
Any suggestions on my original posting?
TIA,
Paul.

Hi,
I've been trying to setup sendmail for local and internet mailing. I have a
dialup account with an ISP.
So far, I've managed to get internal mails working and sending out internet
mails to my ISP for re-routing.
My problem is the receiver of my internet mail can't reply to me as the
reply address is my Linux Server.
How do I configure sendmail such that mails going out to the Internet have
reply headers of my internet account??
Thanks in advance for your help.

Hi,
http://users.nais.com/~nevo/masq/chat.html#icq

ICQ
Submitted by: many many people.
ipautofw -A -r tcp AAAA BBBB -h www.xxx.yyy.zzz
I have taken some discretion here as we've gotten lots of
different solutions to this program. I will summarize
what I have seen as the best method. I would like to thank
everyone who was contributed in getting this working
properly. --Lee
First you will need to run the previous ipautofw command for
each computer that will be running ICQ. You want
AAAA and BBBB to be at least 11 ports apart. That is the
minimum that ICQ will accept without complaining.
Try to seperate the port ranges so the problems with ipautofw
aren't noticed so badly (i.e. 2000-2010). You
want to change www.xxx.yyy.zzz to the ip of the machine running
ICQ.
Then disconnect from the ICQ network. Go into the Preferences
folder/Connections tab and select "Permanent
LAN" and "I'm behind a proxy server/firewall." Then click on
"Firewall Settings" and set ICQ to use the range of
tcp ports from AAAA to BBBB not the default automatic selection
of ports. Finally, reconnect to the ICQ
network to apply the new settings.
Brian Manning has suggested adding a forward for port 4000 to
allow the client machines to go through the
registration process

Here you can find all the infos you need. I used the settings described
above and all worked fine.

Hello Joel.
If you suspect the NTWS then you may want to run a packet decoder during the
login process and see where the delays are occuring. Since you're using NBT
(Netbios over TCP/IP) then a tool like tcpdump on Linux would be able to
capture the traffic.
