Sysadmin

fEmber,

​:heart_trans:​ Request for IT assistance ​:heart_trans:​

Hi friends! Our SysAdmins are still blocked by a network issue that prevents our migration to the new servers. We are running out of ideas and would appreciate any possible support. If you have or know someone who has experience with IPv6 networks, then please contact me or another member of our staff. We would earnestly appreciate any help or advice!

The problem, as I understand it, is that traffic fails to pass through our OPNSense firewall. We have a /48 block allocated on the WAN side, and want to expose a public IP from the LAN. See this reply for a longer description and some discussion.

Boosts appreciated! 💙

Sound like either a RA issue or a misconfigured rule in opensense.

"Enterprise software" ist auch nur ein Synonym für "Zeitverschwendung durch Lizenzprobleme"

@SadKitten @bortzmeyer le standard est de ne pas répondre plus d'une fois par semaine à la même adresse, ça coupe les ping pong

@SadKitten parce que y'a pas assez de place sur les serveurs ?

(19/35) Upgrading xz-libs (5.6.1-r1 -> 5.6.1-r2)

#Alpine #sysAdmin

Thinking of all the Docker images based on Alpine which will never be upgraded against the xz issue...

@bortzmeyer sshd is not linked against liblzma on Alpine. Hence not vulnerable to CVE-2024-3094

Vultr backed down, but so what?

Rights grabs are becoming more common, though. I believe that the only way to stop them is to stop doing business with any company that attempts one. Backing down from a rights grab is too late.

I've recommended them for years. Will be moving off immediately. #sysadmin

No, not a joke.

Well, F***.

Sorry, that's the only thing that came to mind. Thank Cthulhu, I am not hosted with them.

Sigh. So copying and pasting commands from the internet doesn't solve my problem. This means I'm going to have to actually try and /understand/ what's wrong. I didn't sign up for this.

@xdydx I'm trying to mount a Apple Airport Time capsule Samba share on #FreeBSD 14, and so far no luck. I'm lost somewhere between #samba versions, types of security and the fact that FreeBSD seems to have changed the way to deal with Samba shares over the years; and I think from various forum posts I'm getting the different methods confused.

zirias,
@zirias@techhub.social avatar

@hl @xdydx #FreeBSD has only support for SMBv1, which you should absolutely avoid for security reasons, although you can probably configure #samba to still allow it ... but ... don't. Nowadays I'd prefer to say FreeBSD does not support mounting SMB shares.

There are some ports available implementing "modern" SMB (v2/v3) on top of #fuse, which might be an option, but in my experience, they're not perfectly reliable and performance isn't the greatest either.

If ever possible, work on the server side and see whether you can share via #NFS instead. Either #NFSv3 (which is only "secure" as long as your network is perfectly secure and you control all participating machines, but at least it doesn't pretend to do anything else), or #NFSv4 with #kerberos security.

Holy carp.

IANA might be moving on a TLD for internal use. It's only taken, what? Thirty years? That I, personally, have been following this? #sysadmin

@Doomed_Daniel @distractal

They could, but they won't.

You violated a standard that doesn't support what you need, and deserve to be punished. :flan_shrug:

@mwl @distractal
well, I linked a RFC there and it almost recommends using those TLDs, that's gotta count for something
