      Title: Mail: common problems associated with .forward; also see aliases(5)

PROBLEM

A .forward file exists in order to forward mail to a second server.
However, this function does not seem to be working.

What could be causing this condition?

CONFIGURATION

Operating System - HP-UX

RESOLUTION

The following is a list of items to check:

    Check that the .forward file is readable by sendmail.

    Check that the .forward file is NOT attempting to forward
mail back to the server from which it was sent; this is not allowed.

    Please see the man page documentation for aliases(5) for
more information.

      Title: SYS ADM: see umask(1) to set protection mask for files and directories

PROBLEM

How can umask(1) be used to set the protection mode for the
creation of directories and files?

CONFIGURATION

Operating System - HP-UX

RESOLUTION

When files and directories are created, their permission settings - or
"masks" - are set to:

        files: 666 or (rw-rw-rw-)

  directories: 777 or (rwxrwxrwx)

The umask(1) command may be used to specify different settings
as follows:

        Note: the values in the umask(1) command are subtracted
               from the default values. For example:

               files: "umask 022" is interpreted as:

                       666 - 022 = 644 (rw-r--r--)

         directories: "umask 022" is interpreted as:

                       777 - 022 = 755 (drwxr-xr-x)

To take effect system-wide, it is recommended to add umask(1)
to /etc/profile. At a "per-user" level, add this command to the
.profile file for each user.

It is necessary to source the .profile file, or logout/login for
the change to take affect either on a user or a system-wide level.

________________________________________________________________________________

Important Notes at the top:
***************************

   - Modem TR (Terminal Ready) Indicator light.

        With CCITT, this light will be off, even if a getty is running.
        This is NOT a problem, and dialin will still work!
        CCITT uses the RI (Ring Indicator) to handle an incoming call.

   - CLOCAL parameter in gettydefs.

        For CCITT, the CLOCAL parameter in /etc/gettydefs must not be
        set! Setting this parameter poses a security problem! If set,
        the session will remain active when the modem line is disconnected
        without doing an exit.

1. Connect the modem to the "Remote Console Serial Port (Modem)"
    9-pin connector on the N-Class system. The L-Class system has a
    W-Cable with 3 connectors labeled Console, UPS, and Remote. Connect
    the modem cable to the connector labeled "Remote" on the L-Class system.

    Use either the cable supplied with the modem or a 24542M cable. The
    cable supplied with the modem has the number 45880120 on the 25-pin
    RS232 connector.

                         45880120 or
                         24542M Cable
              Modem -------------------> Remote Console
                                          Serial Port (Modem)

    Connect the telephone line to the "Line Jack" RJ45 connector
    on the rear of the modem.

2. Use the GSP CA command to verify that the config matches the
    following:

    Local Console Serial Port bit rate: 19200 bits/s
    Local Console Serial Port Flow Control: Hardware
    Local Console Serial Port Terminal Type: vt100
    Remote Console Serial Port Modem Protocol: CCITT
    Remote Console Serial Port Modem bit rate: 19200 bits/s
    Remote Console Serial Port Modem Flow Control: Hardware
    Remote Console Serial Port Modem Transmit Configuration Strings: Disabled
    Remote Console Serial Port Modem Presence: always connected

3. Use the GSP ER command to set it to "session mode"

    GSP> er
    ER
    Current remote/modem port access: Locked-out
    Do you want to modify this configuration? (Y/[N]) y
    Remote/modem serial port access options:
        [L]ocked-out: Lock out all dial-in access.
        [G]SP : Dial-in results in a GSP login.
        [S]ession : O/S controls modem for dial-in and dial-out
    GSP may page in any mode if modem is not in use.
    O/S may use modem in Session mode only.
    Please indicate the new mode for the remote/modem console serial port,
    or <CR> to retain current value. Choose one of (L, G, S): s
    New remote/modem port access settings will be: Session
    Confirm? (Y/[N]): y
    Command execution may take 25 seconds.
    Current remote/modem port access: Session

4. Create the callin and callout device files

    # mknod /dev/ttyd0p2 c 1 0x000206

    # mknod /dev/cul0p2 c 1 0x000205

    Verify the device files using lssf and ll

    # lssf /dev/ttyd0p2
    asio0 card instance 0 port 2 ccitt callin at address 0/0/4/0 /dev/ttyd0p2

    # ll /dev/ttyd0p2
    crw--w---- 1 uucp tty 1 0x000206 Dec 22 13:23 /dev/ttyd0p2

    # lssf /dev/cul0p2
    asio0 card instance 0 port 2 ccitt callout at address 0/0/4/0 /dev/cul0p2

    # ll /dev/cul0p2
    crw-rw-rw- 1 root sys 1 0x000205 Dec 22 13:31 /dev/cul0p2

5. Edit /etc/uucp/Devices and add the following line:

    Direct cul0p2 - 19200 direct

6. Edit /etc/gettydefs and add the following three lines:
    (There must be a blank line above and below the entry.)

    192 # B19200 SANE CS8 ISTRIP IXANY TAB3 HUPCL
            # B19200 SANE CS8 ISTRIP IXANY TAB3 HUPCL
            #Modem Login: #192

    Note: The "192" in the above lines is a label, which must be unique
          in the /etc/gettydefs file. Please make sure it is not already
          used for another entry in the file.

7. Edit /etc/inittab and add the following line:

    a0:234:respawn:/usr/lbin/uucp/uugetty -r -t 60 -h ttyd0p2 192

    Note: The "a0" in the above line is a label, which must be unique
          in the /etc/inittab file. Please make sure it is not already
          used anywhere else in the file.

8. Start the getty and verify that it is running:

    # init q

    # ps -ef|grep uugetty

    root 1236 1 0 14:12:00 ? 0:00 /usr/lbin/uucp/uugetty -r -t 60
   -h ttyd0p2 192

9. Use cu(1) to connect to the modem

    # cu -l cul0p2 dir
    Connected

    If you get "line problem", use the GSP MR command to reset the modem

10. Configure the modem

     at&w1
     OK
     at&f
     OK
     atz
     OK
     at&s1&c1&d3&w

1.5 MT5634ZBA explanation of Modem settings
________________________________________________________________________________

     - at&w1, at&f, atz
            This resets the modem to it's factory default settings

     - &s1
            Let DSR go high only during connection

       &c1
            DCD goes high when the remote modem's carrier signal is detected,
            and goes low when the carrier signal is not detected.

            These two parameters have to be set in order for the modem to
            disconnect properly.

     - &d3
            If DTR drops, the modem hangs up and resets as if a ATZ command
            were issued.

            This should provide more reliable operation during unexpected
            disconnects.

     - q2
            Do not send result codes during an incoming connection. This
            will prevent the modem from sending (upper case) result codes
            to HP-UX when an incoming call is received.

     - $sb19200
            Set the speed on the modem's RS232 interface to a fixed speed of
            19200 baud.

     - $ba0
            The modem will handle the conversion of the speed differences
            between the modem baud rate and the RS232 serial baud rate.

     - #p0
            Set command mode parity to NONE. This is necessary for the
            remote configuration to work properly. To enter remote config,
            enter %%%ATMTSMODEM <cr>.

     - s2=128
            Disable local escape. This prevents a hang, when the local
            escape (+++AT) is used on the remote modem.
