pppd 2.3.11 - Couldn't attach tty to PPP unit 0

Úterý Září 11 09:07:55 CEST 2001

Dobry den,

vcera jsem si poridil (konecne) modem a jal se zprovoznovat dial-up na
Inet. Bohuzel zatim neuspesne. Pri pouziti pppd deamona (dle clanku na
root.cz a prislusnych HOWTO: Modem, PPP) jsem se size dovolal, ale pote se
do logu vypsalo nasledujici: (chyba oznacena sipkami)

Sep 10 20:16:03 localhost kernel: CSLIP: code copyright 1989 Regents of
the University of California
Sep 10 20:16:03 localhost kernel: PPP generic driver version 2.4.1
Sep 10 20:16:03 localhost pppd[10574]: pppd 2.3.11 started by root, uid 0

Sep 10 20:16:03 localhost pppd[10574]: Couldn't attach tty to PPP unit 0:
Invalid argument
Sep 10 20:16:03 localhost pppd[10574]: tcsetattr: Invalid argument
<<---
Sep 10 20:16:03 localhost pppd[10574]: Exit.
Sep 10 20:16:04 localhost modprobe: modprobe: Can't locate module ppp0

Nevite nekdo, o co jde? Zkousel jsem e v tom vrtat, ale vzhledem k tomu,
ze je to az po pripojeni, nerad bych dal vsechny penize za nalezeni
odpovedi :) A tak se radeji ponizene zeptam.

Modem je seriovy Microcom DeskPorte Pocket, pouzita distribuce je RH 7.0CZ

instalovane moduly: ppp_generic, ppp_async, slhc, serial
jadro: 2.4.9

(POD VLASTNI ZPRAVOU JSOU PRILOZENY KONFIGURACE A DALSI SOUBORY)

# /etc/ppp/options

# The name of this server. Often, the FQDN is used here.
#name <host>

# Enforce the use of the hostname as the name of the local system for
# authentication purposes (overrides the name option).
#usehostname

# If no local IP address is given, pppd will use the first IP address
# that belongs to the local hostname. If "noipdefault" is given, this
# is disabled and the peer will have to supply an IP address.
noipdefault

# With this option, pppd will accept the peer's idea of our local IP
# address, even if the local IP address was specified in an option.
#ipcp-accept-local

# With this option, pppd will accept the peer's idea of its (remote) IP
# address, even if the remote IP address was specified in an option.
#ipcp-accept-remote

# Specify which DNS Servers the incoming Win95 or WinNT Connection should
use
# Two Servers can be remotely configured
#ms-dns 192.168.1.1
#ms-dns 192.168.1.2

# Specify which WINS Servers the incoming connection Win95 or WinNT should
use

# enable this on a server that already has a permanent default route

# Run the executable or shell command specified after pppd has terminated
# the link.  This script could, for example, issue commands to the modem
# to cause it to hang up if hardware modem control signals were not
# available.
# If mgetty is running, it will reset the modem anyway. So there is no
need
# to do it here.

# Increase debugging level (same as -d). The debug output is written
# to syslog LOG_LOCAL2.
debug

# Enable debugging code in the kernel-level PPP driver.  The argument n
# is a number which is the sum of the following values: 1 to enable
# general debug messages, 2 to request that the contents of received
# packets be printed, and 4 to request that the contents of transmitted
# packets be printed.
kdebug 1

# Require the peer to authenticate itself before allowing network
# packets to be sent or received.
# Please do not disable this setting. It is expected to be standard in
# future releases of pppd. Use the call option (see manpage) to disable
# authentication for specific peers.
#auth

# authentication can either be pap or chap. As most people only want to
# use pap, you can also disable chap:
#require-pap
#refuse-chap

# Use hardware flow control (i.e. RTS/CTS) to control the flow of data
# on the serial port.
crtscts

# Specifies that pppd should use a UUCP-style lock on the serial device
# to ensure exclusive access to the device.
lock

# Use the modem control lines.
modem

# async character map -- 32-bit hex; each bit is a character
# that needs to be escaped for pppd to receive it.  0x00000001
# represents '\x01', and 0x80000000 represents '\x1f'.
# To allow pppd to work over a rlogin/telnet connection, ou should escape
# XON (^Q), XOFF  (^S) and ^]: (The peer should use "escape ff".)
#asyncmap  200a0000
asyncmap 0

# Specifies that certain characters should be escaped on transmission
# (regardless of whether the peer requests them to be escaped with its
# async control character map).  The characters to be escaped are
# specified as a list of hex numbers separated by commas.  Note that
# almost any character can be specified for the escape option, unlike
# the asyncmap option which only allows control characters to be
# specified.  The characters which may not be escaped are those with hex
# values 0x20 - 0x3f or 0x5e.
#escape 11,13,ff

# Set the MRU [Maximum Receive Unit] value to <n> for negotiation.  pppd
# will ask the peer to send packets of no more than <n> bytes. The
# minimum MRU value is 128.  The default MRU value is 1500.  A value of
# 296 is recommended for slow links (40 bytes for TCP/IP header + 256
# bytes of data).
#mru 542

# Set the MTU [Maximum Transmit Unit] value to <n>. Unless the peer
# requests a smaller value via MRU negotiation, pppd will request that
# the kernel networking code send data packets of no more than n bytes
# through the PPP network interface.
#mtu <n>

# Set the interface netmask to <n>, a 32 bit netmask in "decimal dot"
# notation (e.g. 255.255.255.0).
#netmask 255.255.255.0

# Don't fork to become a background process (otherwise pppd will do so
# if a serial device is specified).
nodetach

# Set the assumed name of the remote system for authentication purposes
# to <n>.
#remotename <n>

# Add an entry to this system's ARP [Address Resolution Protocol]
# table with the IP address of the peer and the Ethernet address of this
# system. {proxyarp,noproxyarp}
#proxyarp

# Use the system password database for authenticating the peer using
# PAP. Note: mgetty already provides this option. If this is specified
# then dialin from users using a script under Linux to fire up ppp wont
work.
#login

# If this option is given, pppd will send an LCP echo-request frame to
# the peer every n seconds. Under Linux, the echo-request is sent when
# no packets have been received from the peer for n seconds. Normally
# the peer should respond to the echo-request by sending an echo-reply.
# This option can be used with the lcp-echo-failure option to detect
# that the peer is no longer connected.
lcp-echo-interval 30

# If this option is given, pppd will presume the peer to be dead if n
# LCP echo-requests are sent without receiving a valid LCP echo-reply.
# If this happens, pppd will terminate the connection.  Use of this
# option requires a non-zero value for the lcp-echo-interval parameter.
# This option can be used to enable pppd to terminate after the physical
# connection has been broken (e.g., the modem has hung up) in
# situations where no hardware modem control lines are available.
lcp-echo-failure 4

# Specifies that pppd should disconnect if the link is idle for n seconds.
idle 600

# Disable the IPXCP and IPX protocols.
noipx
