Hello Colin
I did this procedure to change the IBMUSER password. It worked for me in a previous version of "Stock image".
Hope this helps
PROCEDURE:
Go to:
cd /home/ibmsys1/volumes
Extract the IEASYM member used by the system when it is loaded with LOADPARM DE28NVM.
pdsUtil /home/ibmsys1/volumes/OPEVS1 SYS1.PARMLIB/IEASYMAU --extract
Modify /home/ibmsys1/volumes/IEASYMAU.txt to update &HOMEIPADDRESS1 and &DEFAULTROUTEADDR variables.
In my current ADCD system (the old ADCD version) I need to use the IP addresses 10.1.1.2 and 10.1.1.1.
SYMDEF(&HOMEIPADDRESS1.='10.1.1.2')
SYMDEF(&VPCVSIIPADDRESS.='&HOMEIPADDRESS1.')
SYMDEF(&DEFAULTROUTEADDR.='10.1.1.1')
Overwrite the data so that when the system starts, it uses that IP and we can connect via SSH
pdsUtil /home/ibmsys1/volumes/OPEVS1 SYS1.PARMLIB/IEASYMAU --overlay
Add tape drives to devmap file (in my case, /home/ibmsys1/volumes/devmap)
[manager]
name awstape 0580
device 580 3490 3490
device 581 3490 3490
device 582 3490 3490
device 583 3490 3490
Generate a SSH key in Ubuntu. We'll need to add the public key to the authorized_keys file for the IBMUSER user on the system.
ssh-keygen -t rsa -b 2048
Copy the contents of /home/ibmsys1/.ssh/id_rsa.pub to a new file named IBMUSER.SSHKEY.
Split the key into multiple lines, each with a record length of 80 characters.
For example:
/home/ibmsys1/volumes/IBMUSER.SSHKEY
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC/xbmg4L0Sl9ad1iZyEw9Q1cNL7o0hdXHRWIkYpqfw
PN40BQs2SClMakUaC/UHwOhysgEwvgbFC7PJOzw3vUoBZeMYaxCSb+APmisB5f9kX8WKiw9fLCwwppf9
nZHVutePslypKWMiLlObLRQyWIT1k/Kx3+6dr002iY7AVTypHjQ89vzni/SogSz5KpzeCpCx4qvpvb7/
Tv2xrUV+qA1utssepaCH6rKpxjwIrCjM17mjGVfRq3y5ABVXxUmEeDLwMWp7M6RQ1dkSzs9p5r1rqlmx
9LoSmkdTqmIVJKNB+wozTAsm1keHF1EBoHXajSP0jU0BGeGSJwBs/i5COiy1 ibmsys1@zdt
Use the following command to copy the file to a new tape. Tape name must be "123456"
card2tape -a /home/ibmsys1/volumes/IBMUSER.SSHKEY /home/ibmsys1/volumes/123456
Start the system using the following LOADPARM:
ipl DE27 parm DE28NVM
On the z/OS System Console, issue the following command:
S SUBMIT,DS=IBMUSER.JCL,M=SSHKYCP
This starts SYS1.PROCLIB(SUBMIT) to execute IBMUSER.JCL(SSHKYCP)
Both members are provided with the "STOCK IMAGE" system.
- 16.34.24 VS01 S SUBMIT,DS=IBMUSER.JCL,M=SSHKYCP
- 16.34.25 VS01 STC00085 IEF404I SUBMIT - ENDED - TIME=16.34.25
*16.34.25 VS01 JOB00086 *IEF233A M 0580,123456,,SSHKYCP,COPYTAPE
Run the following command in the Linux terminal to mount the tape containing the SSHKEY:
awsmount 0580 -m /home/ibmsys1/volumes/123456
16.35.04 VS01 JOB00086 IEF404I SSHKYCP - ENDED - TIME=16.35.04
Now, access to the system via SSH.
ssh ibmuser@10.1.1.2
ibmsys1@zdt:~/volumes$ ssh ibmuser@10.1.1.2
The authenticity of host '10.1.1.2 (10.1.1.2)' can't be established.
ED25519 key fingerprint is SHA256:t32mDPkyHoFE1NKiLtdxt7ObVkoQyH7lObgWZ8EZn9c.
This key is not known by any other names.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '10.1.1.2' (ED25519) to the list of known hosts.
IBMUSER:/u/ibmuser #
Once connected to the system via SSH, issue the following command to set the desired password for the IBMUSER account.
tsocmd "ALTUSER IBMUSER PHRASE('YOUR PASSWORD PHRASE') NOEXPIRE RESUME"
For example:
tsocmd "ALTUSER IBMUSER PHRASE('mainframe12mainframe') NOEXPIRE RESUME"

I see there is a standard image available from passport advantage, but there is little documentation for it.
Does anyone know the password - or any documentation for it?
