sh: /var/tmp/sh7877.13: Cannot create the specified file.

Hi all,

We are facing the following error upon login;


"sh: /var/tmp/sh7877.13: Cannot create the specified file.
[oracle@xxxx][oracle]>"

background of this system, chown / chmod 777 was run by mistake on /usr. It was later fixed by going to single user.

any help in this regard will be appreciable, looking forward for your helpful response.

Regards
Samad

Sure it is fixed?

I don't think so.

What have you done to fix it?


Hope this helps!
Regards
Torsten.

Re: sh: /var/tmp/sh7877.13: Cannot create the specified file.

Since im not system administrator, i don't know how exactly it was fixed. But i have provided the system team the following links, right after i realized i messed up with the system. 

After the incident, no user including root could log in.

https://community.hpe.com/t5/System-Administration/HPUX-11i-how-to-check-for-correct-system-file-permissions/m-p/5075303#M439435

Here is current uptime in multiuser;

[oracle@xxxx][oracle]>uptime
1:31pm up 1 day, 1:20, 5 users, load average: 0.00, 0.00, 0.00

Is there any way we can verify if something wasn't fixed ?

Re: sh: /var/tmp/sh7877.13: Cannot create the specified file.

After every new session created by oracle on both systems, below is the output of tail -400f /var/adm/syslog/syslog.log

Both system are on same release i.e. Release:   HP-UX B.11.31

   Ok.  Considering how likely bad permissions would be on this system,
have you looked at the permissions of "/var/tmp"?

      ls -ld /var/tmp

What about "sh"?

   Compare permissions with those on some system which has not been
damaged (by some fool)?

Re: sh: /var/tmp/sh7877.13: Cannot create the specified file.

What are the permissions on the /var/tmp directory?

 

# ll -d /var/tmp

 

Is there already a file called "sh7877.13" in the /var/tmp directory?  If so, you might have to delete it.

 

# ll /var/tmp/sh7877.13

Im the "fool" who did it, please find below the output required

 

[oracle@healthynode][database]>ll -d /var/tmp
drwxrwxrwt 10 root root 8192 Nov 15 18:47 /var/tmp
[oracle@healthynode][database]>ls -ld /var/tmp
drwxrwxrwt 10 root root 8192 Nov 15 18:47 /var/tmp

 

[oracle@recoverednode][oracle]>ll -d /var/tmp
drwxrwxr-t 8 root root 8192 Nov 15 19:22 /var/tmp

[oracle@recoverednode][oracle]>ls -ld /var/tmp

shxxxx is variable , it changes with every new session.

Here is example of current session:

Confidential computer software. Valid license from HP required for
possession, use or copying. Consistent with FAR 12.211 and 12.212,

[oracle@recoverednode][oracle]>ll /var/tmp/sh29823.13
/var/tmp/sh29823.13 not found.

Re: sh: /var/tmp/sh7877.13: Cannot create the specified file.

On the "recoverednode" system, you /var/tmp/permissions are rwxrwxr-t. and ownership is root:root.  Based on that, nobody but root, or someone in the root group, will be able to create a file.

 

Changing permission to rwxrwxrwx should work.

 

# chmod 777 /var/tmp

 

 >>shxxxx is variable , it changes with every new session.

 

I understand that, but if that file already exists in that directory and is owned by someone else, then a new user won't be able to create a new one.

   To me, those permissions look different.  At least the owner:group
looks plausible.

> Changing permission to rwxrwxrwx should work.

   Perhaps, unless that "t" is actually significant.  I don't have an
HP-UX system up at the moment, so I know nothing, but my handy Mac also
has the "t":

pro3$ ls -ld /var/tmp
drwxrwxrwt 3 root wheel 102 Nov 14 22:02 /var/tmp

So, knowing nothing, I'd probably set the permissions to 1777 rather
than 777.

pro3$ mkdir fred
pro3$ ls -ld fred
drwxr-xr-x 2 sms staff 68 Nov 15 11:38 fred
pro3$ chmod 1777 fred
pro3$ ls -ld fred
drwxrwxrwt 2 sms staff 68 Nov 15 11:38 fred
