# '''Network glitch corrected by Mehrdad where network install (URL copy from Belmont) hung up install due to missing software repository'''.<br>'''Cause''': due to firewall protocol system implementation in Spring/Summer, it blocked the "yum" protocol, and now has been <u>'''fixed'''</u> system-wide.<br><br>'''FYI:''' '''Murray Saul''' verified that the fix worked by successfully created a VM via network install.<br><br>
# <span style="color:red;">'''ATTENTION:'''</span> Mehrdad mentioned that possibly in the next semester (or eventually), the belmont server URLs will be removed. The alternative (and eventual replacement) that affects OPS235/OPS335 is: mirror.senecacollege.ca/centos/7/os/x86_64/<br>Therefore, this corrections should be made for OPS235 and OPS335 labs for the Winter 2018 startup prior to classes.<br><br>
# <span style="color:red;">'''ATTENTION:'''</span> Verify your CentOS release version using '''rpm -qa centos-release'''. If it is '''1708''' <u>and</u> you are using a '''removable hard drive''' with boot issues then do the following: copy '''grubx64.efi''' from [http://mirror.centos.org/centos/7/os/x86_64/EFI/BOOT/ CentOS EFI/BOOT site here] into your /boot/efi/EFI/BOOT directory of your hard drive. To get to that directory of your hard drive you would need to boot from a live CentOS USB or CD/DVD and mount the /boot partition of your HDD. Try to do this yourself, otherwise ask for help from the lab tutor or instructor. You would also need to refresh your grub configuration using help from [https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html-single/System_Administrators_Guide/index.html RedHat], [https://wiki.centos.org/HowTos/Grub2 CentOS] and [http://www.gnu.org/software/grub/manual/grub.html Grub] or use the following [[File:grub.cfg]] for help.
