  11. Hello Everyone , i am reading micheal jangs book for preparing rhcsa and I came across this lab question .I tried doing it with what i read and i couldnt go through .Can any one guide me step by step on how to achieve this task.. here gamma.example.net and whitehat.example.net both are virtual hosts on a physical host system kauai.example.net ... The os i am using is centos 7... PLease guide step by step on how to achieve ... will be thankful In this lab, you install and set up a default configuration HTTP server on the gamma.example.net system. You take the install.log file from the / root directory, and copy it to a newly created /var/www/html/rpmlist directory. Rename that file gamma-install.log. If successful, you'll be able to access the file from remote systems. Log into the whitehat.example.net system, and download the gamma-install.log file with a web browser; use the IP address of gamma.example.net here: [Hidden Content].

  14. Ok... guys, here is a little bit of a problem. A friend of mine faced this issue in the RHCSA (EX-200) exam: In this question: Create a Logical Volume with the name “database” by using 25 extends. From the group “datastore” of 50extends.Consider PE size as 8mb. Format the LVM partition with vfat file system. And mount under /datadb. Well, when trying to format with vfat it is throwing this error: " unable to get drive geometry, using default 255/63 " Redhat.com tells only this much: [Hidden Content] However if we are not formatting an LVM partition, then that same partition is successfully assigned the vfat filesystem with mkfs.vfat. If anyone can help it will be good.

    RHCSA exam

    Hi, I'm planning to take up RHCSA exam. I see that there are a few people here posted the pattern of the exam so wanted to check if anyone has taken this exam recently, and if so,please post if there is any changes in the pattern along with questions if possible. This would be great help. I've practicing for the exam, however, one question that stuck upon me is LDAP client configuration. I heard that for RHCSA it is just LDAP client end configuration, so my question is how to test if this configurations are correct from the client end? Thanks, Murthy,

  21. Hi everyone..i am about to take the RHCSA exam and i have come to the understanding that there are VERY few resources to help understand LDAP everywhere you name it I have these questions and just want you guys to please help me. My main question is how do i ( a ) set LDAp passwod for all users? ( b ) Set LDAP password for a user? ( c ) what does this mean? "While you are able to log in as any of the users guest012 through guest019, the only home directory that is accessible from your system is guest01x." The last thing on the second question Q6: Bind to the LDAP domain redhat.com provided by for user authentication. Note the following: guest01x should be able to log into your system, where x is your station number, but will not have a home directory until you have completed the autofs requirement below you can find LDAP certificate on [Hidden Content] All LDAP users have a password of redhat Q7: Configure autofs to automount the home directories of LDAP users. Note the following: server.redhat.com ( NFS-exports /rhome to your system, where x is your station number guest01x home directory is server.redhat.com:/rhome/guest01x guest01x home directory should be automounted locally beneath /exports home directories must be writable by their users While you are able to log in as any of the users guest012 through guest019, the only home directory that is accessible from your system is guest01x. Thanks a lot guys.

  23. Can anybody confirm the current exam OS? Is it still on RHEL 7.0 or 7.1? Thankyou.
  24. I received an announcement mail from Red Hat saying that: I passed RH202 in 2011 Feb, and gotten RHCT 5 (and I was told that for our case which is near the end of RHEL 5, we were granted RHCA 6 as well). I am preparing to go further, RHCE now. I would like to know, am I eligible for RHCE 6 direct? Is this new announcement helpful to me? If I go for RHCE 7, I will need to take both RHCSA 7 and RHCE 7 exams both. This, I understand. Thanks.
