@hexa:lossy.networkhexaalso a valid choice20:24:05
@hexa:lossy.networkhexaso what happens is that due to too many connection requests ssh also sometimes drops my connect attempts20:25:54
@hexa:lossy.networkhexamildly annoying 🙂 20:26:06
@hexa:lossy.networkhexa

sshd[1969703]: error: beginning MaxStartups throttling

20:26:57
@hexa:lossy.networkhexadue to that20:26:58
@dgrig:erethon.comdgrigAll the things you mentioned help however. I personally change the ssh port, enable fail2ban and for a lot of hosts don't have ssh enabled over the internet since wireguard works good enough for me. Other people I know enable ssh only over tor hidden services, but I don't trust tor starting fast enough after a restart /shrug20:27:01
@magic_rb:matrix.redalder.orgmagic_rbI only allow ssh over wireguard period20:28:33
@dgrig:erethon.comdgrig(waiting for a new circuit after a restart can be a bit annoying if you're trying to ssh right after a restart in my opinion)20:28:36
@scrumplex:duckhub.ioScrumplexAnother way to reduce ssh bot noise is to limit sshd to listen on IPv6 only20:50:50

In reply to @magic_rb:matrix.redalder.org
I only allow ssh over wireguard period
ssh over wireguard is so nice
21:36:06
@hexa:lossy.networkhexayeah, much nicer than just using ssh over internet21:38:07
@hexa:lossy.networkhexa * yeah, much nicer than just using ssh over internet \s 21:38:09
