/dev/lan0 permissions HPUX 11.0

[Jennifer Chiarelli]

Everytime I reboot my L2000 server or a J2240 workstation, the permissions for /dev/lan0 change to 400. Then I have to do a chmod 777.
I don't remember this happening with 10.20 but all my 11.0 systems are doing this. Why is this happening? How can I fix this?

[Jennifer Chiarelli]

I forgot to mention that all of these system do have multiple lan cards installed. But only the L2000 is using more than one lan card. The second lan card in the L2000 is used for the web console.

The correct permission should be 600.

Why are you changing to 777??

[Jennifer Chiarelli]

Joseph,
These systems function as license servers. Users are unable to connect unless I change the permissions.

I checked some of my machines and I had 2 that had permissions of 666 for /dev/lan0 and 4 that had permissions of 600 for /dev/lan0. It seems to make no difference which permissions it has in my environment because users can connect to all machines and our HP Openview machine is one with 600 permission and everything talks to it fine (telnet, rlogin, SNMP traffic, etc.).

How are your users connecting that they can't connect unless you change the permissions? Telnet, rlogin, and all networking services should work fine with 600 permissions.

chmod 600,if you want verify with others lans:
ll /dev/lan*

We had the same problem with our license servers. Put a link in /sbin/rc2.d that points to a script "/usr/bin/chmod 766 /dev/lan0". I set my startup link like this:

ln -s /usr/local/support/fixlan0 S920fixlan0

This is the last entry in my rc2.d directory.

Patrick,

My users are running ProE (CAD software) on MicroSoft NT workstations.

Carl,
Thanks for your response! I intended to do the same. But I still can't help but wonder why this became an issue with hpux 11.0? And it sounds like you had the same issue with users getting a license. In my case it's a Flex license and a system reboot for loss of power will get me a call every time when users can't get their licenses. Changing permissions on lan0 fixes it. I also agree with those above that 666 or possibly 766 would be better. I'll try 666 first. Thanks to all that responded!!
