Boot into single user mode
Load the script and do modification
The loadrc script is located at root directory, you will be in root directory after you have successfully boot to single user mode.
Step 1: Type /loadrc
Step 2: Type /etc/init.d/rc.init
Step 3: Go to /etc/init.d directory, and back up ids_functions script by typing cp ids_functions ids_functions.orig
Step 4: Edit the ids_function script file using vi editor.
Step 5: Search for the key word $IDS4215 in vi /$IDS4215 vi will jump to the location that look like this:
DEFAULT_MGT_OS and DEFAULT_MGT_CIDS to ge0_0 and GigabitEthernet0/0 respectively. Originally it was me0_0 and management0/0
If the DEFAULT_MGT_OS and DEFAULT_MGT_CIDS are not changed to other interfaces and leave it default to me0_0 and management0/0 you will not be able to access the management from Qemu even with correct login credential.
Step 6: Go to /usr/cids/idsRoot/etc/ directory, backup the interface.conf file cp interface.conf interface.conf.orig
Step 7: Edit the interface.conf file with vi editor. Assign the /models/IDS-4215/interfaces from 1 to 6 name-template to GigabitEthernet0/0 to GigabitEthernet0/5.
After reboot you should be able to login with the correct login credential.
