Upvan, apologies in advance for attempting to hijack your thread, but I'm struggling to get guest additions going in VirtualBox.

Background: I've fairly recently been obliged to start learning *nix after 25 years as a mainframe MVS => OS/390 => z/OS systems programmer. The *nix world is a complete and utter mystery to me, and so far I have walked away in disgust and fury from every attempt to get things running.

My Ubuntu image starts and complains about low graphics mode. OK, so I understand I have to install Guest Additions. I've exercised my Google-Fu and have seen all the different ways of doing this. But at the heart of the problem is making the .iso available as a virtual CD-ROM drive to mount. Nothing I've done will make the mount command work.

I have to do this using CLI as the GUI won't work due to low graphics mode. Catch-22.

If any of you kind folks can steer a noob in the right direction I'd appreciate it. If you're willing to help out please dumb it down as much as you can. I'd do the same for someone trying to get a CICS PTF from IBMLink and SMP/E receive it in z/OS!

Once again Upvan, sorry to hijack ...

Now I really feel like a goose. Just goes to show that if you swear enough, then open yourself up to ridicule, the answer will drop into your lap ...

$ sudo blkid ===> this showed that VirtualBox had given this image a CD-ROM
$ sudo mount /dev/sr0 /media/vbox ===> sweet!
$ cd /media/vbox
$ ls ===> see quite clearly the VBoxLinuxAdditions.run file ... so then I did:
$ sudo sh ./VBoxLinuxAdditions.run ===> this appears to have worked as it should. Ends with:
"You may need to restart the hal service and the Window System (or just restart the guest system) to enable the Guest Additions.
"Installing graphics libraries and desktop services components ...done."

I'll enjoy the smug feeling of having completed something before I reboot and have it all (inevitably) unravel.

PAM_GUEST(8)						    BSD System Manager's Manual 					      PAM_GUEST(8)

NAME

     pam_guest -- Guest PAM module

SYNOPSIS

     [service-name] module-type control-flag pam_guest [arguments]

DESCRIPTION

     The guest service module for PAM allows guest logins.  If successful, the pam_guest module sets the PAM environment variable GUEST to the
     login name.  The application can check this variable using pam_getenv(3) to differentiate guest logins from normal logins.

     The following options may be passed to the pam_guest module:

     guests=list    Comma-separated list of guest account names.  The default is ``guest''.  A typical value for ftpd(8) would be
		    ``anonymous,ftp''.

     nopass	    Omits the password prompt if the target account is on the list of guest accounts.

     pass_as_ruser  The password typed in by the user is exported as the PAM_RUSER item.  This is useful for applications like ftpd(8) where guest
		    users are encouraged to use their email address as password.

     pass_is_user   Requires the guest user to type in the guest account name as password.

SEE ALSO

     pam_get_item(3), pam_getenv(3), pam.conf(5), pam(8)

AUTHORS

     The pam_guest module and this manual page were developed for the FreeBSD Project by ThinkSec AS and NAI Labs, the Security Research Division
     of Network Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035 (``CBOSS''), as part of the DARPA CHATS research program.
