I am currently working on a Sun V40z 10 x86 system. I have a requirement to "mv /var/tmp/* /tmp". In the "/var/tmp" directory there is a socket called "mapping-root".

In attempting to move it, I get an error message: "mv: mapping-root: unknown file type 0xc000.

Question: Can I move this? If so, what does it take?

Thank You

This is foolish.
Well, no as the mv command is telling you.

Is that socket in use ? (fuser /var/tmp/mapping-root)

Foolish... not for me to comment. This is a request from a customer who is requiring this task from my section. The box is going off to a vendor for development work at the behest of a government office.

In the parallel setup of SPARC boxes, I have not hit this issue. I have not seen this socket. I cannot find relevant information on the socket. I can probable get around this, but it would require, maybe, a re-build. I was hoping to avoid a time crunch issue.

"fuser /vat/tmp/mapping-root" returns "/var/tmp/mapping-root:"

I am trying to find who owns this socket and what the function.

You should, this is nonsense.
You could at least ask for a rationale behind that request.
Assuming you have the standard Solaris /tmp using tmpfs, you'd rather simply remove all /var/tmp files.
They will be lost anyway when you send that machine to the vendor, or at next reboot, panic or power-outage, whichever comes first ...
Rebuild of what ?
From the fuser point of view, nobody is owning it.

This mapping-root is just telling someone has used JDS (gnome) as root on that server. Using a graphic environment logged in as root is a poor practice, by the way.

You can safely remove it, it will be created again when needed.

Again, I should be happy that the individuals that requested this work, do not have the depth in UNIX. My company was tasked because we have a TestBed with multi-disciplines in contract at the request of the government. So they are eating some "humble pie" as they could not get the initial requiments met.

I will do a late night and start with the boot CD and re-do all the requirements again. I will move the "mv /var/tmp/* /tmp" to earlier in the requiments. As a special note, this box has not been rebooted yet due to the requirement of additianl packages added. I was going to re-boot later. I may do that next and check the "/var/tmp" directory.

I know this, but the prime contractors are Windows type. I am currently doing CLI work from my Mandriva 2006 workstation via "ssh". I use "scp" to move packages to the system.

As an aside, I do have an SCS box, but the all the V40z Sun system won't allow serial connection. Even the local Sun tech had issues. I believe he went "tip hardwire" for access.

I will use your information and check the system after reboot.
Thank You.

You were correct. Once I rebooted the system and logged in via CLI, the socket was able to be removed and the symbolic link created.

Thank You.
