| 03:23 | <alkisg> Sleaker: yeah programs started having issues with chroots years ago, and we don't want to be the ones having to send patches everywhere in order for chroots to work well
| |
| 03:24 | Although, booting them with kvm, lxc, nfs-rw etc etc should be easily feasible

| 09:29 | <kbshk> Hi everyone, my boot fails on trying to mount the filesystems from the server. Both client and server are Debian 10. I've taken screenshots of a few outputs: https://imgur.com/a/P45MgxV
| |
| 09:31 | <alkisg> kbshk: do you happen to have virtualbox installed on the server?
| |
| 09:31 | So that I could quickly test things from a virtual client?
| |
| 09:31 | <kbshk> This is a virtualbox client. Server doesn't have virtualbox.
| |
| 09:31 | <alkisg> I think the problem is that you're not sending a route to the clients
| |
| 09:31 | Ah ok that's fine
| |
| 09:31 | Do you mind sharing your screen?
| |
| 09:31 | What's the host, windows?
| |
| 09:32 | <kbshk> Host is macOS
| |
| 09:32 | <alkisg> Meh you'd need something like x11vnc then, never mind no idea how to share screen from macs
| |
| 09:32 | So:
| |
| 09:32 | <kbshk> ok
| |
| 09:32 | <alkisg> 3rd screenshot
| |
| 09:32 | "network is unreachable"
| |
| 09:32 | At that shell, try:
| |
| 09:32 | ip - o route get 192.168.67.1
| |
| 09:33 | This is supposed to return an address
| |
| 09:33 | I'm thinking that it fails for you, because your dhcp server did not send a gateway
| |
| 09:33 | Btw, you're using bridged mode in vbox, not nat, right?
| |
| 09:33 | <kbshk> Yes, local VM is bridged to OpenVPN tap
| |
| 09:34 | And on the server side, LAN interface bridged to OpenVPN as wel..
| |
| 09:34 | <alkisg> Additionally, also send the output of `ip r`
| |
| 09:34 | <kbshk> And on the server side, LAN interface bridged to OpenVPN as well.
| |
| 09:34 | <alkisg> So, the output of those two commands from that shell in the third screenshot
| |
| 09:34 | <kbshk> Ok, it'll take me a few minutes.
| |
| 09:35 | <alkisg> I will leave in a bit, but we can continue this asynchronously, or another time, or with another person here

| |
| 09:46 | <kbshk> I've run the commands. Looks like there's no default route: https://imgur.com/6xptJ5F

| 10:13 | <alkisg> kbshk: right, that's what you need to fix in your dhcp server
| |
| 10:14 | <kbshk> Yes. I just confirmed this using a packet dump. For some reason my DHCP is spitting out 0.0.0.0 for gateway address. Thank you for the advice.
| |
| 10:14 | <alkisg> np
| |
| 10:14 | you can also fix it from ltsp.conf
| |
| 10:14 | but it's not worth it

| 11:49 | Faith has joined IRC (Faith!~Paty_@unaffiliated/faith) | |
| 12:13 | <kbshk> Fixed it: If you're booting a client through a OpenVPN tap tunnel, use "server-bridge nogw" to stop the OpenVPN server from removing the default gateway from the DHCP reply. Without a gateway set, "ip -o route get 192.168.67.1" will fail and boot won't complete.

| 13:04 | <alkisg> kbshk: that said, if you think it's a valid use case, I can make the code not fail when a gw isn't set

| 13:04 | <alkisg> I left it that way because I had no valid use case with no gateway
