Received signal 10, SIGBUS: invalid access to memory objetcs

[SZCZESNY]

Hello;

I have sometimes problems when using SSH commands from a WIndows Client SSH (plink, ssh.exe ...) to an alpha server :

HP TCP/IP Services for OpenVMS Alpha Version V5.4 - ECO 4 on a AlphaServer 1200 5/533 4MB running OpenVMS V7.3-2

In the SYS$LOGIN of the owner TCPIP$SSH, I found some errors in the associated TCPIP$SSH_RUN.LOG "reeived signal 10, SIGBUS: invalid access to memory objects".

Sometimes the same command is OK, sometimes not.

Can someone help me ?
Thank's.

Hi,

the TCPIP V5.4 ECO 4 release notes contain a paragraph, which may be related to this message:

- The pairing of username and UIC in the sysuaf, as displayed by
SHOW/IDENTIFIER must match that in the user account record. If
there is a mismatch, the following error occurs when the user
attempts to establish an SSH session:

Received signal 10, SIGBUS: invalid access to memory objects.

The workaround is to correct the pairing of username and UIC value
in the sysuaf.

Interresting :

Here are my differents concerned accounts :
1)SSH account
Username: TCPIP$SSH UIC: [3655,12] ([TCPIP$AUX,TCPIP$SSH])

2)APPLICATION account
Username: SGTDEV UIC: [721,721] ([SGTDEV])

3) SSH ID :
TCPIP$SSH [003655,000012]

4) APPLICATION ID :
SGTDEV [000721,000721]

All seems correct. I don't know what to check and why sometimes the same SSH commands with the same account works fine.

Could you help more ?

Hi,

Just a curiousity, but did you install the DECC runtime library kit VMS73_V0600 (SCT 3106) when you upgraded to VMS 7.3? If not - this may very well be your problem. It is mentioned in the ECO 4 release notes that this is required if you are running SSH.

I have OpenVMS 8.1 on an ia64 platform and I am getting the same error when I try to create the SSH keys for the server. Not being an OpenVMS expert, could someone provide me with the precise commands of how to verify the username/UIC pairing? I am not sure what commands to issue in AUTHORIZE...

TIA

Pierre

I think I might have figured out how to check the pairing.

Based on Smiley's comment above, how do I know if the DECC Runtime Library Kit is installed?

Thanks,

Pierre

Pierre, PRODUCT SHOW HISTORY should list the patches installed. Note that VMS V8.1 is not supported -you should move to V8.2

In authorize
SHOW username

and check that the UIC is shown as numbers and as a name e.g
UIC: [100,42] ([SUPPORT,MILLERI])

[Pierre Goyette]

Ian,

I am trying to get my hands on 8.2 or 8.2-1. I just realized that this 8.1 version appears to be beyond unsupported. In the meantime, let me check all my settings:

In AUTHORIZE, if i SHOW TCPIP$SSH, I get:

Username: TCPIP$SSH Owner: TCPIP$SSH
Account: TCPIP UIC: [3655,2] ([TCPIP$AUX,TCPIP$SSH])
...

Then, SHOW TCPIP$SSH/IDENTIFIER displays:

TCPIP$SSH [003655,000002]
...

So, I think the pairing is ok. Correct?

PRODUCT SHOW HISTORY displays:

HP I64VMS DWMOTIF T1.4-1 Full LP Install 21-JUN-2005 14:14:41
HP I64VMS KERBEROS V2.0-14 Full LP Install 21-JUN-2005 14:14:41
HP I64VMS OPENVMS V8.1 Platform Install 21-JUN-2005 14:14:41
HP I64VMS TCPIP T5.5-3T Full LP Install 21-JUN-2005 14:14:41
HP I64VMS VMS V8.1 Oper System Install 21-JUN-2005 14:14:41

Therefore, I assume I don't have the DECC RunTime Library kit. I will look to see if I have this.

Thanks for your help,

Regards,

Pierre

Pierre,

the C Runtime library kit mentioned in one of the previous replies would probably refer to VMS73_ACRTL-V0600. There is no patch like this for V8.1 nor for V8.2, so you don't need to bother to look around for that...

Please also check, whether the username/UIC identifier is correct for the account, you are logged or logging into when issueing the SSH commands.

Volker.

Volker,

Thanks for the info.

I am loggin in as SYSTEM and trying to start SSH from that account. AUTHORIZE show:

UIC: [1,4] ([SYSTEM])

SYSTEM [000001,000004]

Even simple commands like SSH_KEYGEN fail with the SIGBUS message above.

Any ideas?

Pierre

Maybe you can find some time to do some assigning?

Mind, I do NOT say you necessarily need to give lots of points. It is fully up to _YOU_ to decide how many. If you consider an answer is not deserving any points, you can also assign 0 ( = zero ) points, and then that answer will no longer be counted as unassigned.
Consider, that every poster took at least the trouble of posting for you!

To easily find your streams with unassigned points, click your own name somewhere.
This will bring up your profile.
Near the bottom of that page, under the caption â My Question(s)â you will find â questions or topics with unassigned points â Clicking that will give all, and only, your questions that still have unassigned postings.

Thanks on behalf of your Forum colleagues.

PS. â nothing personal in this. I try to post it to everyone with this kind of assignment ratio in this forum. If you have received a posting like this before â please do not take offence â none is intended!

Proost.

Have one on me.
