Subject: PPP hangs after lots of data
Date: Sun, 31 Jan 1999 11:14:55 GMT
Hi!
I have a problem which I think is something to do with pppd. I can dial
out fine, I connect to my ISP fine, names resolve OK, and I can start
doing stuff. Looking at the web, using FTP, ping, telnet, everything
works.
However, after a while (and particularly when I'm sending a lot of data,
rather than receiving it) the connection seems to hang. Not hang UP, the
phone line is still in use and the modems are still talking to each other,
but nothing gets sent.
It seems to be related to packet size as well, and posibly protocol. The
first thing to stop are TCP connections (FTP especially), and ping will
keep on running and getting replies. Then ping stops getting replies
after a while as well.
I've run it with tcpdump looking at ppp0, and what seems to happen is that
the incoming replies stop (for the TCP packets) first, then the outgoing
TCP packets stop (presumably because the window is blocked), then ping
replies (ICMP echo reply) stop, and finally ping (ICMP echo) packets
aren't even sent. At this point, the only thing to do is drop the line
and try again. Using ps, pppd is still there and running, and ppp0 is
still present doing ifconfig.
Note that during all this my local Ethernet is working fine, so it's not
TCP/IP in general that has the problem. Nor is it a routing problem,
route -n gives the same output throughout.
System details:
Pentium 233, 48Mb RAM (notebook machine)
PCMCIA modem card, 33k6 using Cirrus Logic modem chipset
Linux kernel 2.0.34, Debian 2.0 distribution
pppd 2.3.5, installed as binaries from the Debian CD
Connecting using wvdial, pup/pdown or chat, same problem whatever the
method.
If you want further information, traces, logs etc. let me know. Or if
there are some commands I haven't found to look at the state of software
queues or whatever.
I haven't seen anything about this sort of problem anywhere (the problems
usually seem to be initial connection or dropped lines, not failures in
between). If anyone has seen this sort of thing before, any ideas are
welcome...
Note: this is crossposted to comp.protocols.ppp and to
comp.os.linux.networking, because it could be either a pppd problem or a
Linux specific one. If you change it to reply to only one of them, please
keep the subject as c.o.l.n is too busy for my system to handle all the
traffic and I'm filtering on the subject. Or if you put it to some other
newsgroup as more relevant, please mail me and let me know so I can add
it...
Thanks,
Chris C

See 'man smbclient'. It may not be GUI, but it tells you everything=20

Until you ask the client to dial out, that is the correct response from
the server.
If you already have a connection when the cleint is started, then mserver
is
not correctly determining whether or not a connection exists.
My suggestion is do double check the lock file specified in the
mserver.conf file.
I believe that is what it is using to check for a connection with you
config.. The default assumes
a specific file name based on the modem being /dev/modem.
I found it best to create entries patterned after those below as
well to get things working well.

In the file "/usr/lib/X11/xdm/Xservers" change the X-server
startup command to include the "-bpp 24" option.

It works "out of the box" through masquerading just fine with the
proviso that the masquerading process moves the source socket up into
the "unpriviliged" range. This means that "rhosts"-style authentication
won't work and you'll have to give your password.

That'd be a good place to start troubleshooting, anyway; if it
doesn't run in your own local environment, it surely will not run to
get out of your LAN. In any event, ssh is good for use on a local
network anyway as it does compression and X-tunnelling in addition
to being a replacement for telnet and the r* utilities.

Modems do not require special drivers. They inter-act through the AT
commands, unless they are winmodems, which are useless junk for linux.

When we call GTE--Bell Atlantic too?-- the first thing the
sales rep says is the conversation is being taped. Then they
tell us that linux "won't work", and windows is required.
I've heard they will disconnect service if they find out
you're running linux. We have to lie and say we're running
windows, and sometimes their installer refuses to hand
over the modem and splitter and get out of the house
with his stinking windows CD, and he has the
already-turned-on ADSL turned OFF.
So, what do you want to bet MS denies linux users
refunds based on GTE tape recordings where we
confessed under duress to using windows? We're
going to concentration camps, I tell you.

Subject: 3c509b seems ok; but can't ping router
Date: Sun, 31 Jan 1999 14:24:07 GMT
I have an isa 3c509b nic that has worked fine on solaris 2.7, but I
can't ping the router from a cable modem on @home. In solaris I had the
same problem but created a defaultrouter file containing nothing but the
IP of my router and all was well. Now, I have the same symptons with
redhat 5.2. The nic appears fine; I can ping its IP, and 127.0.0.1 but
nothing else.
I downloaded a dos nic configuration utility for the 3c509's and
disabled PNP as another news message suggested, but to no avail. Does
anyone know of a file you need to add to the /etc, like 'defaultrouter'?
Or is there anything else I can try?
Thanks:)

I was looking at the options for my webramp hub, and it had something
about cuseeme using particular UDP ports, like telnet, ftp, xfstt.
netmeeting must do that, too.

Section option:
force create mode
Quote from man smb.conf
This parameter specifies a set of UNIX mode bit permis-
sions that will *always* be set on a file created by
Samba. This is done by bitwise 'OR'ing these bits onto the
mode bits of a file that is being created. The default for
this parameter is (in octel) 000. The modes in this param-
eter are bitwise 'OR'ed onto the file mode after the mask
set in the "create mask" parameter is applied.
See also the parameter "create mask" for details on mask-
ing mode bits on created files.
Default:
force create mode = 000
Example:
force create mode = 0755

Try going to http://www.panthersfootball.com/ppp/linuxinst.tar.gz, and get
that file. It's a perl script that configures your files correctly, after
getting input from you, eg. ISPs nameservers, etc. After it's doing
