How to reset the Web Admin/GUI Username or Password in CUCM

Oops you forgot the username or even the password and can't login to your CUCM?  As long as you can login to the CLI you can use these commands:

Reset the username (eg. you don't recall what username you specified as the web admin GUI user!)

utils reset_application_ui_administrator_name

You need to reset the web admin GUI password

utils reset_application_ui_administrator_password

Network will not work after changing VM NIC Mac Address:

I have even mounted the image using: guestmount -a cucm12-publisher.img -m /dev/sda1 mount

I have tried the below but it still not work.  Neither does setting the IP manually or by DHCP or by setting the network up and down.

Then I deleted /etc/udev.d/rules.d/70-persistent-net.rules since it has the old MAC address.  It then gets regenerated by udev properly upon reboot.  You could change the file and edit the MAC but that breaks things for SELINUX

# line, and change only the value of the NAME= key.

# PCI device 0x1af4:0x1000 (virtio-pci)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="52:54:00:12:34:56", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x1af4:0x1000 (virtio-pci)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="b3:24:a8:f3:fe:ee", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

CUCM 12 Partition Layout:

/dev/sda1 has all of your typical Centos/RHEL /etc stuff and OS config as you would expect

It seems the networking /etc scripts don't entirely change or control things as expected.

/dev/sda2 on a new install is empty

/dev/sda3 is grub

Filesystem                           1K-blocks       Used  Available  Use%
cucm12-publisher.img:/dev/sda1        21688188   12498224    8968292   58%
cucm12-publisher.img:/dev/sda2        21688188      44992   20534820    1%
cucm12-publisher.img:/dev/sda3          245679       2323     230249    1%
cucm12-publisher.img:/dev/sda6        75790432   14875408   57058384   20%

/dev/sda6 has a lot of interesting stuff:

adminsftp                  bps          certs     drf  lost+found  ontape_backup_done  pns          sdlhelper  stlphelper          upload  whousesme
backup-sysctl.conf.append  capture.txt  download  log  moh         ontape_backup.gz    rpm-archive  spy.py     sysctl.conf.append  var
