Not knowing much about the German telecommunications system, I'll throw
a few ideas at you.
Did you disable call waiting?
Did you disable originator-mask?
Is your modem configured for the German telecommunications system? (for
some reason, most dialers/modem controllers default to the US system -
in most countries, using out of bounds dialling mechanisms is illegal(!))
=======================================================================
From the HP page on pppd:
pppd is a daemon process used in UNIX systems to manage connections to
other hosts using PPP, the Point to Point Protocol, or SLIP, the Serial
Line Internet Protocol. It uses the UNIX host's native serial ports. It
communicates with the UNIX kernel's own TCP/IP implementation via the HP
IP tunnel driver (see tun(4)).
Daemon Management Options
auto
Start in `autocall' mode and detach from the controlling terminal to run
as a daemon. Initiate a connection in response to a packet specified in
the `bringup' category in filter-file. Requires the remote address.
up
When used with auto, bring the link up immediately rather than waiting
for traffic. If the link goes down, attempt to restart it (after the
call retry delay timer expires) without waiting for an outbound packet.
dedicated
Treat the connection as a dedicated line rather than a demand-dial
connection. This option tells pppd to never give up on the connection;
that is, if the peer tries to shut down the link, go ahead and do so,
but then immediately try to reestablish the connection. Similarly, when
first trying to connect, pppd will not give up after sending a fixed
number of Configure-Request messages. Hangup events (LQM failures, loss
of Carrier Detect) will still cause the device to be closed, just as
with dial-up connections, and the Systems file will then be checked for
alternate entries. If none are available, the connection will be
reestablished after the call retry delay timer expires. Use a short call
retry delay timer on dedicated circuits; something like Any;5-30 should
work well. Implies up.
nodetach
Don't detach from the controlling terminal in `autocall' mode. When used
with log -, this can be useful for watching the progress of the PPP session.
log log-file
Append logging messages to log-file (default: /var/adm/pppd.log).
acct acct-file
Append session accounting messages to acct-file. If acct-file is the
same as log-file, the session accounting messages will be interleaved
with other logging information.
filter filter-file
Look in filter-file for packet filtering and link management information
(default: /etc/ppp/Filter).
debug debug-level
Set the log file verbosity to the following debug-level and each
debugging verbosity level also provides the information of all the
lower-numbered levels.
0
Daemon start messages
1
Link status messages, calling attempts (the default)
2
Chat script processing, input framing errors
3
LCP, IPCP, PAP and CHAP negotiation
4
LQM status summaries
5
IP interface changes
6
IP message summaries
7
Full LQM reports
8
All PPP messages (without framing)
9
Characters read or written
10
Procedure call messages
11
Internal timers
exec exec-cmd
Run `exec-cmd up addr args' when the link comes up, and `exec-cmd down
addr args' when it goes down. Addr is the IP address of the peer, and
args is the list of arguments given to pppd.
nonice
Run at a normal user process priority, rather than using the nice()
library routine to elevate pppd scheduling priority to -10.
Communications Options
asyncmap async-map
Set the desired Async Control Character Map to async-map, expressed in
C-style hexadecimal notation (default 0xA0000).
noasyncmap
Disable LCP Async Control Character Map negotiation.
escape odd-character
In addition to those characters specified in the PPP Async Control
Character Map (which can include only 0x00 through 0x1F), also apply the
escaping algorithm when transmitting odd-character. The value of
odd-character must be between 0x00 and 0xFF, and cannot be any of 0x5E,
0x7D or 0x7E.
Odd-character can be specified as a decimal number, in C-style
hexadecimal notation, or as an ASCII character with optional `^'
control-character notation. For example, the XON character could be
specified as 17, 0x11, or ^Q.
If a character specified with the escape argument, when transformed into
its escaped form, would be the same as a character contained in the
peer's negotiated Async Control Character Map, a warning will be printed
in the log file and the character specified on the command line will not
be escaped.
If a character specified with the escape argument, when transformed into
its escaped form, would be the same as a character specified in another
escape argument on the daemon's command line, pppd will print an error
message and exit.
device
Communicate over the named device (default /dev/tty).
comm-speed
Set communications rate to comm-speed bits per second.
ignore-cd
Ignore the state of the CD (Carrier Detect, also called DCD, Data
Carrier Detect) signal. This is useful for systems that don't support CD
but want to run PPP over a dedicated line.
xonxoff
Set the line to use in-band (`software') flow control, using the
characters DC3 (^S, XOFF, ASCII 0x13) to stop the flow and DC1 (^Q, XON,
ASCII 0x11) to resume. (The default is to use no flow control.) For an
outbound connection, this may be specified either in Devices or on the
pppd command line.
telnet
When used on an answering pppd command line, negotiate the telnet binary
option and understand telnet escape processing. Not for use with device
or auto.
Link Management Options
nooptions
Disable all LCP and IPCP options.
noaccomp
Disable HDLC Address and Control Field compression.
noprotcomp
Disable LCP Protocol Field Compression.
slip
Use RFC 1055 SLIP packet framing rather than PPP packet framing.
Disables all option negotiation, and implies noasyncmap, noipaddress,
vjslots 16, novjcid, nomagic, nomru, and mru 1006. Implies vjcomp if
peer sends a header-compressed TCP packet.
extra-slip-end
When running in SLIP mode, prepend a SLIP packet framing character
(0xC0) to each frame before transmission, even if this frame immediately
follows the previous frame. By default, pppd transmits only one framing
character between adjacent SLIP frames.
nomagic
Disable LCP Magic Number negotiation.
mru mru-size
Set LCP Maximum Receive Unit value to mru-size for negotiation. The
default is 1500 for PPP and 1006 for SLIP.
nomru
Disable LCP Maximum Receive Unit negotiation, and use 1500 for our
interface.
active
Begin LCP parameter negotiation immediately (the default).
passive
Do not send our first LCP packet until we receive an LCP packet from the
peer.
timeout restart-time
Set the LCP, IPCP, CCP, PAP, and CHAP option negotiation restart timers
to restart-time (default 3 seconds).
lqrinterval time
Send Link-Quality-Reports or Echo-Requests every time seconds (default
10 seconds). If the peer responds with a Protocol-Reject, send LCP
Echo-Requests every time seconds instead, and use the received LCP
Echo-Replies for link status policy decisions.
lqthreshold min/per
Set a minimum standard for link quality by considering the connection to
have failed if fewer than min out of the last per LQRs we sent have been
responded to by the peer (default 1/5).
echolqm
Use LCP Echo-Requests rather than standard Link-Quality-Report messages
for link quality assessment and policy decisions. The peer can override
this if it actively tries to configure Link Quality Monitoring unless
the nolqm parameter is also specified.
nolqm
Don't send or recognize Link-Quality-Report messages. If echolqm is also
specified, Echo-Request messages will be used to detect link failures.
idle idle-time[/session-idle-time]
Shut down the link when idle-time seconds pass without receiving or
transmitting a packet specified in the `keepup' category in the filter
file (default is to never consider the link idle).
If session-idle-time is specified and any TCP sessions are open, shut
down the link when session-idle-time seconds pass without receiving or
transmitting a packet.
max-configure tries
Set the PPP Max-Configure counter (the maximum number of
Configure-Requests sent without a response) to tries .
max-terminate tries
Set the PPP Max-Terminate counter (the maximum number of
Terminate-Requests sent without a response) to tries .
max-failure tries
Set the PPP Max-Failure counter (the maximum number of Configure-Naks
sent without a positive response) to tries .
IP Options
local:remote
The address of this machine, followed by the expected address for the
remote machine. Can be specified either as symbolic names or as literal
IP addresses, if their addresses cannot be discovered locally without
using the PPP link.
Both addresses are optional, but a colon by itself is not valid, and the
remote address is required when running as a daemon in `autocall' mode.
If only local: is specified when receiving an incoming call, the remote
address will be discovered during IPCP IP-Address negotiations.
If either address is followed by a tilde character (`~'), or if the
tilde appears alone, pppd accepts the IP address given by the peer
during IPCP negotiations, whether for the local end or the peer's end of
the link. (not available in SLIP mode)
Because SLIP cannot perform option negotiations, including IPCP, both
addresses should normally be specified, and the tilde option is
unavailable. To obtain a similar "feature", the peer must provide the IP
address textually during the login process, and a new value must be
obtained using the Systems file `\A' chat script feature (see
ppp.Systems(4)).
netmask subnet-mask
Set the subnet mask of the interface to subnet-mask, expressed either in
C-style hexadecimal (e.g. 0xffffff00) or in decimal dotted-quad notation
(e.g. 255.255.255.0). The default subnet mask will be appropriate for
the network (class A, B, or C), assuming no subnetting.
noipaddress
Disable IPCP IP-Address negotiation.
vjcomp
Enable RFC 1144 `VJ' Van Jacobson TCP header compression negotiation
with 16 slots and slot ID compression (this is the default with PPP
framing). `VJ' compression is enabled by default for async connections,
and disabled by default for sync connections.
novjcomp
Disable RFC 1144 `VJ' Van Jacobson TCP header compression (this is the
default with SLIP framing, until the peer sends a header-compressed TCP
packet).
vjslots vj-slots
Set the number of VJ compression slots (min 3, max 256, default 16).
novjcid
Disable VJ compression slot ID compression (enabled by default).
rfc1172-vj
Backwards compatibility with older PPP implementations (4-byte VJ
configuration option), but with the correct option negotiation value of
0x002d.
rfc1172-typo-vj
Backwards compatibility with older PPP implementations (4-byte VJ
configuration option) that conform to the typographical error in RFC
1172 section 5.2 (Compression-Type value 0x0037).
rfc1172-addresses
Backwards compatibility with older PPP implementations that conform to
RFC 1172 section 5.1 (IP-Addresses, IPCP configuration option 1) and not
with the newer RFC 1332 (IP-Address, IPCP configuration option 3), but
that respond with something besides a Configure-Reject when they receive
an IPCP Configure-Request containing an option 3.
Authentication Options
requireauth
Require either PAP or CHAP authentication.
requirechap
Require CHAP authentication as described in RFC 1334.
requiremschap
Require MS-CHAP authentication.
requirepap
Require PAP authentication.
rechap interval
Demand that the peer re-authenticate itself (using CHAP) every interval
seconds. If the peer fails the new challenge, the link is terminated.
name identifier
Provide the identifier used during PAP or CHAP negotiation. This option
is necessary if the PPP peer requires authentication. The default value
is the value returned by the gethostname(2) system call or the
hostname(1) command.
MicroSoft Compatibility Options
ms-dns address
Set the MS DNS address to provide to the peer. First occurrence of this
option on the command line sets the primary address; the second
occurrence sets the secondary address.
ms-nbns address
Set the MS NBNS address to provide to the peer. First occurrence of this
option on the command line sets the primary address; the second
occurrence sets the secondary address.
Encryption Options
Encryption is not currently available in software exported from the USA.
However, customer may contact sales@progressive-systems.com to obtain
encryption functionality.
Link Compression Options
compress
Offer all supported link compression types (currently only Predictor-1)
when negotiating. The default is to propose and accept no link
compression type.
compress-pred1
Accept any supported compression type, but prefer Predictor type 1
compression.
nopred1
Never use Predictor-1 compression.
LOG FILE
Status information is recorded in the log file (/var/adm/pppd.log by
default) by each copy of pppd running on a single machine. Each line in
the file consists of a message preceded by the date, the time, and the
process ID number of the daemon writing the message. The quantity and
verbosity of messages are controlled with the debug option and with the
log filter (see ppp.Filter(4)).
Each packet that brings up the link (at debug level 1 or more), each
packet that matches the log filter (at any debug level), or any packet
when the debug level is 7 or more writes a one-line description of the
packet to the log file. The first item of the message is the protocol
(tcp, udp, icmp, or a numeric protocol value ). For ICMP packets, the
keyword icmp is followed by the ICMP message type and sub code,
separated by slashes. After the protocol comes an IP address and
optionally a TCP or UDP port number, followed by an arrow indicating
whether the packet was sent (->) or received (<-), followed by another
address and port number, followed by the length of the packet in bytes
before VJ TCP header compression, followed by zero or more keywords. For
transmitted packets, the first IP address is the source address, while
for received packets, the first IP address is the destination address.
Well known TCP and UDP port numbers will be replaced by the name
returned by the getservbyport() library function. The keywords and their
meanings are:
frag
The packet is a middle or later part of a fragmented IP frame.
syn
The packet has the TCP SYN bit set.
fin
The packet has the TCP FIN bit set.
bringup
The transmitted packet matches the bringup filter and is bringing up the
link.
!keepup
the packet has been rejected by the keepup filter.
!pass
The packet has been rejected by the pass filter.
dial failed
The packet was dropped because pppd is waiting for the call retry timer
to expire.
(c)
The received packet is VJ TCP header compressed.
(u)
The received packet is VJ TCP header uncompressed.
For example, the following log file line
9/6-14:06:26-83 tcp 63.1.6.3/1050 -> 8.1.1.9/smtp 44 syn
indicates that at 2:06:26 PM on September 6, process ID 83 sent a
44-byte TCP packet with the SYN bit set from port 1050 on 63.1.6.3 to
the SMTP port on 8.1.1.9.
SIGNALS
Upon reception of the following signals, pppd closes and reopens the log
file, re-reads the filter and key files, then takes the indicated actions:
SIGKILL
Don't use this. Never, never use this. Since pppd won't be able to shut
down gracefully, it will leave your serial interfaces (whether /dev/tty)
and your IP tunnel driver in some unknown state. Use SIGTERM instead, so
pppd will shut down cleanly, and leave the system in a well-defined state.
SIGINT
Disconnect gracefully from an active session. If in `autocall' mode,
reset the call retry delay timer and call retry backoff interval. If up
was specified, attempt to re-establish the link. Exit if not in
`autocall' mode.
SIGHUP
Disconnect abruptly from an active session. If up was specified, attempt
to re-establish the link. Exit if not in `autocall' mode.
SIGTERM
Disconnect gracefully from an active session, clean up the state of any
serial and IP interfaces that are open, then exit.
SIGUSR1
Increment the verbosity level for debugging information written to the
log file.
SIGUSR2
Reset the debugging verbosity level to the base value (1 unless debug 0
was supplied on the command line).
SIGALRM
Take no action except to re-read the filter and key files.
EXAMPLE
To run a pair of daemons on `oursystem', one maintaining a constant link
with `backbonesystem' and the other prepared to initiate outbound calls
to a neighboring machine named `theirsystem', add the following to
/sbin/rc2.d/S522ppp:
if [ -f /etc/ppp/Autostart ]; then
/etc/ppp/Autostart
fi
Then make /etc/ppp/Autostart look like this:
#!/bin/sh
PATH=/usr/etc:/bin:/usr/bin
if [ -f /var/adm/pppd.log ]; then
mv /var/adm/pppd.log /var/adm/OLDpppd.log
fi
echo -n "Starting PPP daemons:" >/dev/console
pppd oursystem:backbonesystem auto up
(echo -n ' backbonesystem') >/dev/console
pppd oursystem:theirsystem auto idle 120
(echo -n ' theirsystem') >/dev/console
echo '.' >/dev/console
To allow a PPP implementation running on `theirsystem' to dial into
`oursystem', insert the following into /etc/passwd on `oursystem':
Pthem:?:105:20:Their PPP:/etc/ppp:/etc/ppp/Login
where group 20 is the gid of the ppp group which owns /usr/etc/pppd, and
/etc/ppp/Login is an executable shell script that looks something like
#!/bin/sh
PATH=/usr/bin:/usr/etc:/bin
mesg n
stty -tostop
exec pppd `hostname`:
RECOMMENDATIONS
Use host names when running /etc/ppp/Autostart from /sbin/rc2.d/S522ppp
only if they are known locally. If a PPP connection to a DNS server
would be required to resolve a host name, use its literal IP address
instead.
EXTERNAL INFLUENCES
Environment Variables
The environment variable PPPHOME, if present, specifies the directory in
which pppd looks for its configuration files (Filter and Auth for all
connections, along with Systems, Devices, and Dialers if the connection
is `outbound'). You can specify PPPHOME either in the Autostart script
or in an incoming connection's Login script. If PPPHOME is not present,
pppd will expect to find its configuration files in /etc/ppp/*.
SECURITY CONCERNS
pppd should be mode 4750, owned by root, and executable only by the
members of the group containing all the incoming PPP login `users'.

STANDARDS CONFORMANCE
HP PPP implements the IETF Proposed Standard Point-to-Point Protocol and
many of its options and extensions, in conformance with RFCs 1548, 1549,
1332, 1333, 1334, and 1144. It can be configured to be conformant with
earlier specifications of the PPP protocol, as described in RFCs 1134,
1171, and 1172. It implements the nonstandard SLIP protocol as described
in RFCs 1055 and 1144.
