| ===== Naptastic Network Playbook ===== | ===== Naptastic Network Playbook ===== | ||
| - | + | ====Partition drives==== | |
| - | == Pre-install | + | |
| Partitioning: | Partitioning: | ||
| - | apt -y install curl vim whois | + | Add / |
| - | Make sure to enable contrib, non-free, non-free-firmware in / | + | ====Move ~ to a BTRFS subvolume==== |
| + | Separate snapshotting the OS from snapshotting your files. | ||
| - | Comment out svcrdma in /etc/rdma/modules/rdma.conf or nfs-kernel-server won't start. I'm not sure what's **actually** needed to make NFS/RDMA work. | + | ====SSH key for root==== |
| + | mkdir /root/.ssh | ||
| + | chmod 700 /root/.ssh | ||
| + | curl https:// | ||
| - | ==== All systems | + | ====Reconfigure SSH==== |
| - | * network interface names. Can I automate this? (Of course I can.) | + | Configure ssh for a high-numbered port, and not to allow password-based logins. Restart sshd. Verify that 'ssh root@localhost' |
| - | * Profile stuff: Bash, Vim, ? Can I automate this? (Of course I can.) | + | |
| - | * Network stuff. Too much goddamn customization. | + | |
| - | * disable journald; configure logging for everything. | + | |
| - | * Make a list of things that need to log | + | |
| - | * How exactly do I want logging set up? | + | |
| - | === All systems with Mellanox adapters | + | ====Backups==== |
| - | * mst* installer | + | Create / |
| - | * copy production opensm configuration | + | |
| - | * (what needs to change here for VMs using virtual functions?) | + | |
| - | If your host is going to do audio stuff, follow the LAD playbook. Which also badly need an update. | + | # / was on / |
| + | UUID=some-long-string / | ||
| + | UUID=some-long-string / | ||
| - | If your host is going to host web stuff, follow the LAMP playbook but keep in mind it's badly out-of-date. Be prepared to search, read docs, look for a better way. | + | ====Install Shorewall==== |
| - | ===== Getting Started ===== | + | * customize interfaces, rules, policy...? |
| + | * / | ||
| + | * / | ||
| + | * systemctl enable | ||
| + | * reboot a bunch of times because it's not passing traffic for no reason | ||
| - | Perform a network install of Debian. | + | ====Pick the best mirror==== |
| + | If the repo is installed or mounted locally: | ||
| + | deb file:/// | ||
| + | deb-src file:/// | ||
| - | run the naptastic installer if it didn't run as part of the installer: | + | If you have to get it via HTTP: |
| + | deb http:// | ||
| + | deb-src http:// | ||
| - | curl https://naptastic.com/initial.sh | /bin/bash | + | If you have to use public mirrors (RIP): |
| + | deb http://deb.debian.org/debian/ bookworm main contrib non-free non-free-firmware | ||
| + | deb-src http:// | ||
| - | # This is not necessary unless the installer failed to do it. | + | ====Remove crap==== |
| - | | + | |
| - | chmod 700 / | + | |
| - | curl https:// | + | |
| - | Configure ssh for a high-numbered port, and not to allow password-based logins. Restart sshd. Verify that 'ssh root@localhost' | + | ====Install extra packages==== |
| + | (This is set up so you can triple-click each block you need, copy/paste or middle-paste into your terminal, then press enter at the end and install everything in one transaction.) | ||
| - | == Check out /etc == | + | apt -y install curl vim whois |
| - | (You forwarded your agent, right?) | + | Hardware hosts add: |
| + | | ||
| - | git clone git@github.com:naptastic/ | + | Desktops: |
| - | | + | hexchat synaptic terminator fonts-lohit-knda fonts-knda keepassx evolution virt-manager network-manager-gnome |
| - | cd /etc | + | |

| - | and see where you stand. | + | Audio workstations: |

| + | Name=emo0 | ||

| - | check / | + | * emoX for ports on the motherboard |
| + | * enX for (multi-)gigabit stand-up cards | ||
| + | * ibX for InfiniBand IPoIB devices (these do not need .link files though) | ||
| + | * mlxX for Mellanox devices in Ethernet mode | ||
| - | The answer, somehow, | + | ===Port Conventions=== |
| + | X is 0-indexed. Port 0 on a stand-up card is the farthest from the motherboard. On a motherboard, it's the left-most port if there' | ||
| - | Some of my systems are using ifupdown, and some I'm not sure how they work, and some don't work right. Linux networking is fucking terrible. | + | ===InfiniBand=== |
| - | + | | |

| + | * copy production opensm configuration in case you have take over as SM | ||
| + | * (what needs to change here for VMs using virtual functions?) | ||

| - | ===== Options ===== | + | ====Hugepages==== |
| + | Useful for databases, PHP, Factorio, and probably other things! Add something like this to / | ||
| - | maybe you feel like it, maybe you don't. idk. **This will be replaced with customized preseed files**. | + | vm.nr_hugepages=512 |
| - | == For all systems == | + | To make a non-persistent change, |
