Bugs I've encountered and fixed (started loggin since Jun 24th).
- When trying to kinit username
- ERROR: kinit: Cannot contact any KDC for realm [your realm fqdn] while getting initial credentials
- SOLUTION: 1. check log file. I looked in /var/log/auth.log. The bottom of it says: Cannot create reply cache file /var/tmp/krb5kdc_rcache: File exits. 2. sudo rm /var/tmp/krb5kdc_rcache.
- Can't start krb5kdc and in auth.log it says:
- ERROR: Address already in use - Cannot bind server socket to port [#] address [IP address]
- SOLUTION: 1. see if it is true that port [#] is in use by netstat -nap | grep [#] (I also did pgrep -x krb5kdc). 2. kill the process: pkill -x krb5kdc. note the "-x" is for matching exactly the process "krb5kdc".
Tips. Useful little things to know
Python
- p = Popen('blah', stdin=PIPE, stdout=PIPE, stderr=PIPE)
- (out, err) = p.communicate('inputThing\n') <-- don't forget the return "\n" at the end!
