I can do that with my regular key file. But I'm trying to limit this key so it can only cat data to the log file.

I won't be there to type in a passphrase or password, so security has to be a little weak. But I want to limit the weakness as much as possible.

Race condition with PTY

I've been experimenting with pseudo-terminals and found something I don't quite understand. Writing an EOF character to the master end doesn't work quite as I expect. Once I've written any other data, the master pty seems to treat a single ^D as a seperator, i.e. writing "abcabc" would let cat do... (1 Reply)

kstash

KSTASH(8)						    BSD System Manager's Manual 						 KSTASH(8)

NAME

     kstash -- store the KDC master password in a file

SYNOPSIS

     kstash [-e string | --enctype=string] [-k file | --key-file=file] [--convert-file] [--random-key] [--master-key-fd=fd] [--random-key]
	    [-h | --help] [--version]

DESCRIPTION

     kstash reads the Kerberos master key and stores it in a file that will be used by the KDC.

     Supported options:

     -e string, --enctype=string
	     the encryption type to use, defaults to DES3-CBC-SHA1.

     -k file, --key-file=file
	     the name of the master key file.

     --convert-file
	     don't ask for a new master key, just read an old master key file, and write it back in the new keyfile format.

     --random-key
	     generate a random master key.

     --master-key-fd=fd
	     filedescriptor to read passphrase from, if not specified the passphrase will be read from the terminal.

FILES

     /var/heimdal/m-key is the default keyfile if no other keyfile is specified.  The format of a Heimdal master key is the same as a keytab, so
     ktutil list can be used to list the content of the file.
