Ideally (as written in distrib.its), you'd like to have a file somewhere where you set your system name, IP address and other configuration data, and let ITS read it at startup. Unfortunately, that's not the way it works…

NOTE that all $ below are ESCAPEs!! Also, where it says XY, you should substitute your new system name.

NOTE that you should read distrib.its before you do any of this, so you know what you're doing! This is just summing up the stuff, filling in some details. If you're happy with one of the standard names (AI, ML, MC, MD, MX…) and don't plan on interacting with other ITS systems, it's much easier to forget the whole thing.

SYSHST;H3TEXT >

change name of address or add new entry

SYSTEM;CONFIG >

copy IFE MCOND MD,[ … ] to IFE MCOND XY,[ … ], make changes inside

SYSTEM;TTYTYP >

copy MCONDX MD,{ … } to MCONDX XY,{ … }, no changes needed?

SYSNET;TELSER >

maybe add a line over TCPOL

SYSEN2;MLDEV >

add to where NX appears (twice) - only needed on OTHER systems to reach THIS ONE!

SYSEN1;PWORD >

• add to mchtab (don't forget to up mchcnt)
• add to bltspc, corresponding spec (copy from mdspec-mdspe)
• add to devtab(?)

SYSEN1;DDT >

(this is not mentioned in distrib.its)

• add to mchtab
• add after RFLNSC
• maybe add to nodflt

L;*LISP >

after UDIRSET, add your name

L;STRUCT >

search for MRA [ITS,AI,ML,MC,MD,MX and add your name

SYSEN1;SENDER >

search for MX, add similar code

SYSENG;LUSER >

add a MACTAB entry, add to lists following

• TELSER:

      :midas .temp.;_sysnet;telser
      :copy .temp.;telser bin,sysbin;telser bin 

• DDT:

      :midas .temp.;_sysen1;ddt
      ddt$j
      $l .temp.;ddt bin
      purify$g
      :pdump sys;atsign ddt 

• PWORD/PANDA:

      :midas .temp.;_sysen1;pword (twice, answer no and yes)
      :copy .temp.;pword bin,sysbin;
      :copy .temp.;panda bin,sysbin; 

• and if you haven't already done this,

      :link sys;atsign pword,sysbin;pword bin
      :link sys;ts panda,sysbin;panda bin
      :link sys;atsign hactrn,sysbin;pword bin 

• ITS:

      :midas .temp.;_system;its 

  (type in your new system name IN UPPERCASE)

Dump .temp.;its bin as described in distrib.its and restart with the new ITS.

Let programs repurify: run each of these once

:peek
:name
:probe
:meter
:prufd
:sysmsg

and purify MIDAS:

midas$j
$l sysbin;midas 458bin
purify$g

Patch DUMP so it knows where it's running (you could also just recompile SYSENG;DUMP).

dump$j
$l sysbin;dump bin
setsc1+34//$1'XY$	(note double slash, insert your system name for XY here)
:pdump sysbin;dump bin
