SCO SYSV on a HP server. Install notes

Phone extension that rings multiple external numbers (CCME Asterisk)

Skip to end of metadata

o to start of metadata

In this example we want to ring all the external numbers of a few people only by dialing extension 3331.

1: Connect to CCME and create a new dial-peer:

dial-peer voice 3331 voip
 description External Emergency Responders
 destination-pattern 3331$
 session protocol sipv2
 session target ipv4:192.168.0.XXX #(the Asterisk box)
 dtmf-relay rtp-nte cisco-rtp
 codec g711ulaw
 no vad

2: Connect to the asterisk server and add the extension in the default [incoming_context] in /etc/asterisk/extensions.conf: (192.168.0.YYY is the outgoing trunk)

exten => 3331,1,Dial(SIP/5145555555@192.168.0.YYY&SIP/51455555519@192.168.0.YYY&SIP/5145555552@192.168.0.YYY&SIP/5145555553@192.168.0.YYY&SIP/5145555554@192.168.0.YYY&SIP/5145555555@192.168.0.YYY)
exten => 3331,n,Hangup

3: Reload asterisk config and test the extension 

Limit number of unix logins

cat .profile

#!/bin/sh
limit=3

session=`ps -ef | grep '\-sh' | grep $USER | grep -v grep`

number=`echo $session | wc -l`

if [ $number -ge $limit ]; then
echo "No more logins / Il n'y a plus de login. You are already logged as:
$session "

sleep 5
exit 0
fi

# to timeout after 15min of inactivity and forbid users to change the tmout:
echo "TMOUT=900
readonly TMOUT
export TMOUT" > /etc/profile.d/tmout.sh && chmox +x /etc/profile.d/tmout.sh

Forward all emails from one sendmail to another

- in sendmail.cf change Djdomain.tld to something like Dj_subdomain.domain.tld Do the same thing for DMdomain.tld
- in the same sendmail.cf look for Fw or Fw-o and check the file it refers to (usually /usr/lib/mail/local-host-names); in that file remove the line stating "domain.tld" (in fact, remove everything, leave just _subdomain.domain.tld there), that way sendmail will know that it is not the default destination for the @domain.tld

- if necessary, create /home/$username/.forward (chmod 600, chown $username:$group) and put the right info in it

Dell Latitude Keyboard light

The backlit keys interface seems to be broken, so you need to mask the controlling service: systemctl mask systemd-backlight@leds\:dell\:\:kbd_backlight.service
then go to BIOS and and change the keyboard led timeout from 10s to 5s for AC Power and Battery mode - "For some reason if the kbd_backlight service is not masked, it somehow forces the bios led timeout back to 10s, and then the keyboard led always remains lit."

SCO SysV Cannot enable remote printing (mkdev rlp) after the installation of an Update Pack 2/3 or a Maintenance Pack

"Unable to get complete data for 'Printer Manager on ...
Failed to retrieve list of remote printers.    
The TCP/IP rlp remote printing package is not installed...."
According to the documentation of Update Pack x and Maintenance
          Pack x, "mkdev rlp" MUST be run before applying Update Pack x or
          when including CUPS as part of the installation of the Maintenance
          Pack as detailed in:
         
          CUPS and Remote Printing (LPD)
         
          Although CUPS supports LPD as both a server and a client, the CUPS
          LPD server implementation does not support access control (based on
          the settings in the /etc/hosts.equiv and /etc/hosts.lpd files).
          If your setup requires the use of the standard LPD, or you wish to
          use access control, do not install CUPS.
WARNING  If you have never run mkdev rlp and you wish to do
          so, the CUPS package must be removed before running mkdev rlp
          and then reinstalled after remote printing is configured.
on a system-wide basis in /etc/default/lpd. The default entry is
            for the SYSV print system:

            PRINT_SYSTEM=SYSV


NOTE:
          If you already had run "mkdev rlp" and have added the Maintenance
          Pack and are now unable to run "scoadmin printer" -> Printer ->
          Add Remote (ie. (UNIX) ) is not able to be highlighted to add new
          Remote Printers then the cause is /usr/lib/mkdev/rlp is missing.

          The file 'rlp' is kept in /usr/lib/lp/sysv/save and can be copied
          back to /usr/lib/mkdev/rlp

          This issue has been reported to SCO Engineering.

NOTE:
          If you need CUPS to be removed in order for you to use LPD as
          detailed above in the Maintenance Pack installation notes BUT also
          require SAMBA to be used then please note that the removal of CUPS
          will also remove a number of libraries vital to Samba from /usr/lib:

          libcups.a@
          libcups.so@
          libcups.so.2@
          libcupsimage.a@
          libcupsimage.so@
          libcupsimage.so.2@

          Which should be copied and placed back into /usr/lib after CUPS has
          been removed in order for SAMBA 3.0.20A to function otherwise you
          may see:

          # /etc/init.d/smb start
          dynamic linker : /usr/sbin/smbd : could not open libcups.so.2
     

DR/Migrate Sco SysV

1)      Reinstall SCO Base system

2)      Copy /etc/conf to a backup directory (ie: copy –ormv /etc/conf /usr/rcvr/conf)

3)      Remove all contents of /etc/conf (cd /etc/conf && rm –r /etc/conf/*)

4)      Change file creation mask on root filesystem (cd / && umask 0)

5)      Restore tape excluding /dev & /stand (cpio –icvdmufB< /dev/rStp0 “dev/*” “stand/*” )

6)      Copy ttytype & inittab to backup directory (ex: cp /etc/inittab /usr/rcvr/ )

7)      Use SCOadmin to relink the kernel

8)      If asked to rebuild environment answer (y)YES

9)      Put back inittab & ttytype form the backup (ex: cp /usr/rcvr/inittab  /etc/inittab)

     10)     Reboot & have a Beer

Your system administrator does not allow the use of saved credentials to log on to the remote computer RDP terminal server because its identity is not fully verified.

In order to use saved RDP or Terminal Server credentials you need to do the following:

1. On the local machine, Open Group Policy Editor via Run -> gpedit.msc

2. Navigate to Local Computer Policy>Computer Configuration>Administrative Templates>System>Credentials Delegation

3.Open Setting Allow Delegating Saved Credentials with NTLM-only Server Authentication, set it to Enabled click on button Show... and in Show Contents window add Value TERMSRV/*. Close the windows by pressing OK.

*Repeat step 3 on the following settings:

Allow Delegating Default Credentials

Autodiscover and/or EWS unavailable on Exchange 2007/2010

Symptom: Outlook crashes or you cannot access OutOfOffice settings after you install a package that contains the .NET Framework 3.5 with SP1 and the .NET Framework 2.0 with SP2 on an Exchange 2007 or on an Exchange 2010 server (CAS role)

Problem described in:
kb958934
kb952883
kb976814


My solution:

Turn of any mmc, powershel console, emc etc.

Uninstall .net 3.5 sp1
Uninstall .net 3.0 sp2
Uninstall .net 2.0 sp2

In this order, without restarting!
if it complains that "you can't uninstall, some other package depends on it", do this:

net stop MSExchangeTransportLogSearch /yes
net stop MSExchangeTransport /yes
net stop MSExchangeServiceHost /yes
net stop MSExchangeSearch /yes
net stop MSExchangeRepl /yes
net stop MSExchangePop3 /yes
net stop MSExchangeMailSubmission /yes
net stop MSExchangeMailboxAssistants /yes
net stop MSExchangeIMAP4 /yes
net stop MSExchangeFDS /yes
net stop MSExchangeSA /yes
net stop MSExchangeEdgeSync /yes
net stop MSExchangeAntispamUpdate /yes
net stop MSExchangeADTopology /yes
net stop MSExchangeIS /yes
ping -n 5 -w 1000 1.0.0.0 >nul
net stop w3svc /yes

If you still can't uninstall, use procexp's "find" feature and close any .NET handle still open.

At the end there should be no reference to .NET in the installed programs.
DO NOT RESTART!

Install .net 3.0 (I used version 3.0.4506.30 downloaded in 2008 an forgotten on server...)
DO NOT RESTART!

If you receive Error 401 when attempting to run Test-OutlookWebServices | FL, disable the loopback check in  HKLM\SYSTEM\CurrentControlSet\Control\Lsa  "DisableLoopbackCheck" DWORD, 1

- In IIS Manager make sure ASP.NET 2.0.50727 is ENABLED
- In IIS Manager make sure Autodiscovery and EWS uses only "Integrated windows authentication" and that the security cert is "require ssl", "128 bit" and "ignore client certificates"

- Verify that the folder %ExchangeInstallaDir%\ClientAccess\Autodiscover is readable by "authenticated users"
 - perform iisreset /noforce

[PS] Test-OutlookWebServices | FL should give you a good answer now, if not, make sure the autodiscover DNS entry exists:

- in DNS Manager rightclick the local forward lookup zone, "Other new records", "SRV", service "_autodiscover", pri "10", weight "5", port "443", host "autodiscover.domain.tld"
- in DNS Manager, new A-Record "autodiscover.domain.tld"
