  5. Hi, I have another suggestion. Having just tried exam ex200 and not even being able to start it, due to the first question (which I am not allowed to mention) can I please please ask you for the sake of others to add a small section about “how to change the root password when that password is not known/not given”. This avoids wasting time in turning up for the exam as well as the 500 euros (the price in The Netherlands) plus vat thx a lot

  6. Hi. Can I make a suggestion on the LDAP section? As I was going through the steps, I decided to do the ldap client side first, so issued:

    # yum update && yum install openldap openldap-clients nss-pam-ldapd
    

    and this worked fine. The next part, however, did not:

    # systemctl enable slapd.service
    

    as it could not find it.

    It turned out that this part was part of the ‘server’ setup, but that was not clear. So I installed openldap-servers and then the command worked.

    The next hurdle was this: creating the ldaprootpasswd.ldif file. It did not state ‘where’ to place it, so in the end I realized it could be anywhere.

    [[email protected] ~]# ldapadd -H ldapi:/// -f ldaprootpasswd.dif
    SASL/GSS-SPNEGO authentication started
    ldap_sasl_interactive_bind_s: Local error (-2)
    	additional info: SASL(-1): generic failure: GSSAPI Error: 
    Unspecified GSS failure.  Minor code may provide more information (SPNEGO cannot find mechanisms to negotiate)
    

    Google pointed me at this website: https://bugzilla.redhat.com/show_bug.cgi?id=1206910

    which suggested I add an extra parameter “-Y EXTERNAL” … and then it worked:

    [[email protected] ~]# ldapadd -H ldapi:/// -f ldaprootpasswd.dif -Y EXTERNAL
    SASL/EXTERNAL authentication started
    SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
    SASL SSF: 0
    modifying entry "olcDatabase={0}config,cn=config"
    

    Might be worth making some additional comments in the LDAP section.

    Cheers … Ruud

  7. Hi, On page 54 the RHCSA pdf states:

    Let’s give user gacanepa read and write access to /mnt/playground/testfile.txt. Run as root

    # setfacl -R -m u:gacanepa:rwx /mnt/playground
    

    and you’ll have successfully added an ACL that allows gacanepa to write to the test file.

    This is not correct. It should say:

    # setfacl -R -m u:gacanepa:rwx /mnt/playground/testfile.txt
    

    This is the second ‘typo’ I have found in this pdf. When will you make the corrections for the next person who pays for the pdf?

    Regards
    Ruud

    • @Ruud,

      Thanks for pointing out the mistake in RHCSA section, we will correct all typos in the next updated version of pdf, till then stay tuned to TecMint..

    • I think maybe both these are wrong. if were giving access for a specific file, we don’t need the -R (--recursive). So it looks like the only thing that needs to be changed from the original command is to include the filename in the path and remove the -R.

      # setfacl -m u:gacanepa:rwx /mnt/playground/testfile.txt

  8. Example 7: Creating hard and soft links
    There is no better way to visualize the relation between a file and a hard or symbolic link that point to it, than
    to create those links. In the following screenshot you will see that the file and the hard link that points to it
    share the same inode and both are identified by the same disk usage of 466 bytes. On the other hand,
    creating a hard link results in an extra disk usage of 5 bytes

    The last sentence should read … On the other hand, creating a SOFT link results in an extra disk usage of 5 bytes

    cheers … Ruud
