kumars10

I this scenario i am getting "invlaid control file format". It happens only to the use kumars10 and which have a 8 char while other working users have only 7 char user id, like kumarts.

so i am looking for any hidden enrties or some thing which i am not able to identify and which could cause an error reported

here is the binary i use to enable/disable the id.When enabled the control file (/opt/local/unix/eracc/var/eracc/ediemerg) occupies a particular user id and when disabled it become a blank line file with file size 1.

here is the binary i use to enable/disable the id.

I am not sure if that binary is some thing which HP supports or provided by HP.

any suggetions would be appreciated.

I'm lost. What are you trying to do?

> i am getting "invlaid control file format".

From what? "eracc"? What is that?

[A. Clay Stephenson]

eracc is not a standard command and "invalid control file format" only has meaning with respect to some application that reads this file. You better hunt up the documentation or contact the developer.

[F Verschuren]

the od looks fine to me, I can not see anny strange behaver in the commands you have posted.

can you please try to explean the problem you are facing?

ps eracc is not standart hp. (as far I can findout)

[skt_skt]

yes it is not HP's tool.

I am in touch with the developer now to check the source code ..

[skt_skt]

it was a bug in the code in the c program.

Wrong:
/* read one line from control file */
fgets(readbuf,MAXLNLEN+1,fd);
fclose(fd);

Fixed:
/* read one line from control file */
fgets(readbuf,MAXLNLEN+2,fd);
fclose(fd);
