Revision as of 14:41, 27 July 2014
Along with the complete overhaul of the network comes a complete overhaul of this page. As the network will have rough edges for a while, so will this page.
Information
Networks
| Description | VLAN ID | IP Space |
|---|---|---|
| WAN | 100 | 24.96.165.224/29 |
| DMZ | 200 | 10.56.0.0/24 |
| Trusted LAN | 300 | 10.56.1.0/24 |
| Guest LAN | 400 | 10.56.2.0/24 |
| VPN | - | - |
Procedures
Convert a normal logical volume to a DRBD
Delegates
Road Map
- Migrate one VM host (vm2?) to be running on top of old kratos hardware.
- Fix DNS FQDN wonkiness.
- Establish VPN solution.
- Establish backup solution.
- Set up all boxes to email to netadmin when they have problems (forward root email).
- Establish Xen management system
- One of [1] most likely; Ctrl+F xen
- Begin updating and upgrading VMs
- Establish general host management system
- For VMs and physical boxes alike, but mostly the VMs; probably Ajenti if it's a good fit
- Establish non-Zimbra password-changing app.
- Perhaps a general LDAP management app, to replace the ldapadmin script.
- Migrate from Zimbra's integrated LDAP to slapd (of some variety).
- Look for remaining items that depend on Zimbra, address these, and decommission Zimbra.
News
Newest on top.
- Lots of stuff going on! Two new VM hosts vm2 and vm3 are set up on the exact same platform, same xen and drbd and debian versions, etc... VM migration is working well between these. Some VMs (backup) run on vm3, the rest currently run on vm2. We need to get a machine beefy enough to run all VMs again - old kratos can do this, and I THINK the hardware on that is in a usable state (all failed parts replaced) now. So that's on the top of the to-do list now. (I may move it down, depending on what I feel like doing - there's high demand for VPN for sure.) So anyway, we can cross these off the list:
- Enable live migration of all VMs between 2-3 VM hosts.
- Set up netadmin list and send welcome messages, etc.
- Replace disk in kratos with 300GB VelociRaptor.
- Holy hell, disk failures left and right. Tl;dr: kratos is now a switchvox box, it's got another failing disk in it, vm2 is hosting everything, none of the boxes are really workable (kratos has failing disk again and vm2 has no RAM). Good news is we have a new box thanks to [User:Compuhacker] that has a lot of RAM and is generally good. So we can use that, at least for a while, and vm2 seems to be supporting the essentials in the meantime.
- router reconfigured to support adding dhcp clients' host names to its /etc/hosts, and it is therefore now responding to NS requests for these names. the fqdn is something like hfuller-pc.256.makerslocal.org. I also made one minor change to allow the switch and router to detect each other over cdp. Hfuller (talk) 01:36, 14 May 2014 (CDT)
- hfuller@router# compare
- [edit service dhcp-server]
- >hostfile-update enable
- [edit service]
- +lldp {
- + legacy-protocols {
- + cdp
- + }
- + management-address 10.56.1.1
- +}
- router (UBNT EdgeRouter Lite) updated to UBNT software version 1.4.1 to hopefully fix our dhcp issues. There are some cool new features, too. Hfuller (talk) 01:36, 14 May 2014 (CDT)
