Subject: RPC: Timed out, in 2.2.0 only
Date: 27 Jan 1999 16:50:17 GMT
I'm trying to run a 486/33 as an X terminal, running XFree86 3.3.3
on Linux 2.2.0. One of the systems on our network is a Motorola
88100 running SystemV/88; when I try to NFS-mount a file system from
the Motorola box I get an "RPC timed out" message and the mount
fails. When I try to rlogin to the Motorola box the session hangs
immediately and eventually dies with a message about "address already
in use". When I try to telnet to the Motorola box I get the "Login:"
prompt but no response to the keyboard; the session eventually times
out. I can, however, rlogin from the Motorola box to the 2.2.0 Linux
box, and I can run an xterm on the Motorola box and display it on the
Linux box. This problem also occurred with 2.2.0-final, but not with
any of the 2.0.x kernels through 2.0.35.
The Motorola box is the only one displaying this problem; the 2.2.0
box communicates successfully with boxes running Digital UNIX, AIX,
SCO, ISC, DG/UX, and Solaris. Anyone have suggestions on where I can
start looking for the cause of this problem?

Hello...
I've just setup a small home LAN with private IP addresses.
RH5.2 = 192.168.0.1
Win98 = 192.168.0.2
I *can* ping from each box to each box. I *can* get RH5.2 HTTP services from
Win 98 using http://192.168.0.1
My problem is, I can't telnet or FTP... in both operations it seems to find
the machine, but no login prompts are ever issued.
Any suggestions?
Thanks in advance...David

You will need IP aliasing, and routing in the kernel(just enable
anything ;-)
> Can I do it with oine ethernet card and masqerading or aliasing ?
one computer has to act as a router. You will need a second interface
named eth0:0
or something like that, which is configured for the 192.168.0.xxx net.
All the clients must have a routing entry which says that the router is
the gateway for
the 192.168.0.xxx net.
never tried it but it shuold work.

If you are talking about pppd, I don't think there is any way to jump=20
out of that into the shell. It can safely run suid root.
I do ipfwadm and enable/disable ip-forward from ip-up(.local) or=20
ip-down(.local) based on remote IP range (same modem used for dialin=20
and dialout). You can either do that or do settings from=20
/etc/rc.d/rc.local on startup.

Subject: LINUX PPP on a SPARC10
Date: Wed, 27 Jan 1999 12:01:20 -0500
Hi,
Though I'm using a Sparc10 with RH 5.1, the ppp setup should be trivial
under linux. I getting a "LCP: timeout sending" problem.
=
I've tried 2 modems (microcom 28.8p, microcom 56k), changed serial
cable, disabled the eth0 interface while connecting PPP and I'm still
getting the same problem. =
I suspecting a netmask problem or interrupts problem but I need help
to validate (or invalidate) these hypothesises.
=
BTW: To connect to my ISP, I'm using a DIP script. When ppp is started
on my SPARC I can see the modem SD led glowing (sending a lot of
stuff to the ISP port) and small burst FROM the ISP port.

The following is a sample of my configuration and my logs
(/var/log/messages).

Subject: DialD Problem
Date: Sun, 24 Jan 1999 23:51:25 GMT
Hi, I came across a problem with DIALD... not sure if this is normal or not.
DialD works great, but there is one problem I have found. After a session has
no activity, it disconnects. Fine. Now the problem, sometimes DialD just
stops repsonding to network requests while in the waiting state. I endup
sending a HUP to reset DialD and this usually works. Is there something I may
have overlooked that may resolve this.
Thanks.

Ok, i didn't knew you had sendmail.
First of all try telneting into it to know if it's allowing you to
send mails. type something like
$telnet 127.0.0.1 25
you should have something like
220 ppp246-221.vif.com ESMTP Sendmail 8.8.7/8.8.7/Emmanuel CARJAT
26/09/98; Sun, 24 Jan 1999 17:22:31 -0500
if not try to loosen the security via the /etc/hosts.allow and
/etc/hosts.deny
If it still doesn't work, well i have no clue but if you're not a
purist you might have a look at the fetchmail mda command.

Reply-To: [EMAIL PROTECTED]
I have a problem.
I am using Redhat 5.2
On my linux box I have 2 adapters eth0 & eth1.
Netstat reports that they are both operational and up.
eth0 is assigned a "real" class "c" address 111.111.111.110 netmask
255.255.255.0
eth1 is assigned a internal ip address 192.168.2.1 netmask
255.255.255.0
our gateway is 111.111.111.1
all i want to do is allow several computers on the 192 net use the
Linux box as a gateway to reach the internet.
BTW I can ping the internet gateway 111.111.111.1 from the Linux Box
but on the W95 box connected to the 192 segment I cannot ping anything
outside the 192 area code. What gives ?
I Played with the routing tables and it seems like the Linux box
cannot send packets from 192 to the 111.
I did a traceroute on the linux box using the eth1 interface and it
timed out trying to get to the gateway.
I have went through several FAQ's but to no avail.
I am testing this to provide access to the internet for a classroom in
our school if it works we will probaly dump NT as our core internet
servers. (HTTP on linux is much faster than on NT)
Please help if you can.
