lsof says it can't stat() fusefs filesystem #153

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Connect to a server with SSHFS
2. Open a terminal
3. Run 'sudo lsof -i TCP' to see all current TCP connections

What is the expected output? What do you see instead?

I'm not sure what the expected output is, because I can see the underlying
ssh connection.

This is my output:

capriccioso:~ hakan$ sudo lsof -i TCP
lsof: WARNING: can't stat() fusefs file system /Volumes/kovs.shacknet.nu

(The exact IP has been somewhat censored. Hope you don't mind.)

What version of the product are you using? On what operating system?

Using SSHFS 0.2.0 and MacFUSE 0.2.5, OS X 10.4.9

Heh, this is the third "permissions" related issue reported this week.

Try the command without the "sudo".

By default, for a volume, MacFUSE denies all access to any user (*including* 
the super user) except the one 
that mounted the volume. The point is that a user file system daemon can do 
potentially dangerous things to 
root/system processes, so as a precautionary step, MacFUSE limits access to its 
volumes.

Of course, if a super user wants to unmount somebody else's MacFUSE volume, 
they can use "sudo" to do the 
unmount, just kill the user file system daemon, or use some other means.

Aha, I see. Indeed it doesn't warn when running without sudo. The reason I use 
sudo
is because I want to see also things like any connections to my server (which is
running as another user).

Thanks!
