Zimbra and Ubuntu Upgrade

Currently running Zimbra (free) 8.6.0 1194. 1194 was a patch and there have been later patches released for 8.6.0, but weren’t installed. The OS is currently running Ubuntu 14.04 LTS

Zimbra 8.6.0 is not available for Ubuntu 16.04. I had tried to upgrade the OS to 16.04, but it failed miserably and resorted to a VM restore. I will need to upgrade Zimbra to 8.7 and above before upgrading the OS.

Upgrade of Zimbra to 8.7 requires memcache and proxy to be installed first. To do this, I will need to reinstall 8.6.0. and select the options to install memcache and proxy. The 8.6.0 version available to download is 8.6.0.1153. I’m not sure it’s necessary, but I will install the available patch, which is now 1242. There is a comment in the release notes that the web client will say Network, but to ignore it and it will still be the free open source version.

After the installation of memcach and proxy with 8.6.0, repeat the install process, but with 8.7.0

GhettoVCB

I’m using GhettoVCB to backup my ESXi 7.0 (free version) to an NFS share. The NFS share is advertised by a VM on the ESXi host using a pass-through USB device for storage.

File Locations
/vmfs/volumes/DS_02/Scripts/ghettoVCB.conf
/vmfs/volumes/DS_02/Scripts/vms_to_backup
/opt/ghettovcb/bin/ghettoVCB.sh

Scheduled
/var/spool/cron/crontab/root
0 5 * * * /opt/ghettovcb/bin/ghettoVCB.sh -f /vmfs/volumes/DS_02/Scripts/vms_to_backup -g /vmfs/volumes/DS_02/Scripts/ghettoVCB.conf > /dev/null

Restart cron
kill -$(cat /var/run/crond.pid)
/bin/crond

Firewall
NFS uses TCP and UDP port 2049, so they are allowed through firewall

Backup one VM using m option
./opt/ghettovcb/bin/ghettoVCB.sh -m [vm] -g /vmfs/volumes/DS_02/Scripts/ghettoVCB.conf

GSN3

I recently installed GNS3 as a VM on my ESXi server (free version). I did this to study for the new CCNA and Encore certs. I then run a GNS3 client on my Mac that connects to the VM. I’m limited on how many nodes I can have running in a project, because it becomes memory intensive on the server.

I’m running GNS3 server version 2.2.16

I recently upgraded my Macbook. OS X Big Sur has an issue with GNS3 client and will not start. I started using the GNS3 web gui http://[GNS3 server IP]:3080. This is working well for me, but occasionally the project will close. I’m guessing it’s a resource issue so I limit the number of nodes I turn on and save often.

I know it’s not secure, but I configured the Untangle firewall to allow port 3080 to the GNS3 server. The policy is only allowing my work’s public IP range. This is so I can access GNS3 web gui from work without using a VPN.
