lanadmin -x works but coredumps HPUX 11.11

Hi Admins,

My problem is the lanadmin command. It works fine but generates a small core dump. I hope this can be resolved. Can S.O. help me.

Re: lanadmin -x works but coredumps HPUX 11.11

please post also a
what core

with the core generated, so we can see why it gets its core, sig_sev, sig_bus...

Also: i see a "NO LINK", this measn there cable is not OK.

Maybe lanadmin is complaining because of this.

do you have a core also with boards with a good cable in ?

Re: lanadmin -x works but coredumps HPUX 11.11

Hi Massimo,

This is on an other server:

ptc55b01:/root #lanadmin -x 1
Current Config = 10 Half-Duplex AUTONEG
Memory fault(coredump)
ptc55b01:/root #what core

100BT : dsbtlan.c $Revision: r11.11/2 $Date: 2001/01/25 15:40:49 $
$ PATCH_11.11/PHCO_28427 Apr 17 2003 23:25:55 $
92453-07 dld dld B.11.18 000922

So its not the cable or the server i think its a software problem.

Re: lanadmin -x works but coredumps HPUX 11.11

i have a couple of things in mind:

- first (least possible) is your /stand mounted?
i saw lanadmin core dump when /stand is umounted.

- does lanadmin work on every other board ?
- is the problem related to all your hpux 11.11 systems ?

The last two question are just to track down the problem...

Can you post also a "file core" ?

Try step by step first
select lan
select ppa
select 1,2,3 whatever you want

Did you take a backup?

Re: lanadmin -x works but coredumps HPUX 11.11

I agree with Robert-Jan, check the patch before you go any further. The fact is the program works, so if there was any sort of connectivity problem it would tell you.

Re: lanadmin -x works but coredumps HPUX 11.11

I just checked the patch text referred to above,didn't spot the defect referred to directly : did see in HP an exact match : internal defect id = JAGae69344 due to a memory fault caused due to an unititialized variable/pointer in lanadmin code.

A patch should be out this month .... *maybe* PHNE_28923 but DO NOT take this as 100 % certain that that's its name or timescale ... appologies I can't be more specific.

Re: lanadmin -x works but coredumps HPUX 11.11

Thanks All,

/stand is mounted...

Its related to all UX11.11 servers.

#file core
core: core file from 'lanadmin' - received SIGSEGV

The patch PHNE_28799 is not installed, but i like to wait for the PHNE_28923 patch mentioned by Alex. Thanks all for your time..

I will give feedback when this patch does or does not do the trick.

How's the status?

I do have the same problem happened on one of my hpux11i server. Core file was generated when execute lanadmin -x 1, same terminate signal.

Re: lanadmin -x works but coredumps HPUX 11.11


We still did not install the patch since we just finished upgrading to Dec 2002....So i an not give you feedback. Since it does work it is not our biggest proi. Will update this tread if we do upgrade.
