OpenVMS system administration
(draft)
 
Basic commands
Shut the system down or reboot,
@sys$system:shutdown
ref http://labs.hoffmanlabs.com/node/1078
 
Change directory, for example,
set default sys$update
list files,
dir
execute,
@vmsinstal
 
One level down,
set default [-]
 
Copy, rename, recursive copy, delete
copy
backup/verify
rename
delete
 
Create, edit,
create file.txt
edit file.txt
 
Fix file permissions, for example,
set file/protectio=o:rwed filename
 
Change password,
set password
 
 
Basic administration
Check the disk space,
show device sys$sysdevice
 
Check the memory,
show memory/full
 
 
A few hints
OpenVMS tailoring,
run sys$update:vmstailor
 
DECwindows tailoring,
run sys$update:decw$tailor
 
 
Reset system's password
Boot the drive in sysboot mode,
>>> show dev
>>> boot/1 dka200
Note. abreviated commands also work (b/1 ...)
 
Either use the uaf console backdoor,
SYSBOOT> show uafalternate
SYSBOOT> set uafalternate 1
SYSBOOT> continue
or get to the OPA0 console ($) prompt,
SYSBOOT> set/startup opa0:
SYSBOOT> set window_system 0
SYSBOOT> set writesysparams 0
SYSBOOT> continue
 
With the UAF method, you can now login as SYSTEM while providing anything you want as password.
 
Eventually change the system-wide password, use MODIFY /SYSTEM command in the AUTHORIZE utility.
 
When finished, you'll have to retore the defaults. On the former,
set uafalternate 0
and against the latter,
set/startup sys$sytem:startup.com
  set writesysparams 1
show window_system
show writesysparams
