#SSH

1 post1 participant0 posts today

Man, #ssh never ceases to amaze me.

Just learned (after 15years on #linux) that you can execute a command on a remote host using the ' ' convention.

E.g.; ssh root@host 'date' will 1) start a connection, 2) execute date on the remote host 3) return the output of date 4) and finally close the connection.

Even better you can pipe things to the command. So echo "dog" | ssh root@1.x.x.x 'wall' will send the word "dog" to all logged in users.

I should have assumed something like this exists

@torproject Q: I wish there was a similar tool test #Bridges, as bridges.torproject.org/scan/ is not that good and I don't want to hammer it with dozens of addresses, cuz at best that's quite antisocial if not possibly trigger responses assuming this is an intelligence gathering operation.

  • Ideally sone standalone binary that one can just give a list of #TorBridge|s in a text file (similar to the way one can just past them in at #TorBrowser) would help.

I.e.

bridgetest -v4 obfs4 203.0.113.0:80 …

bridgetest -v6 webtunnel [2001:DB8::1]:443 …

bridgetest -list ./tor.bridges.list.private.tsv
  • But maybe #onionprobe already does that. In that case please tell me to "#RTFM!"

Similarly there needs to be a more granular way to request #TorBridges from #BridgeDB (as it's basically impossible to get #IPv4 #Webtunnel addresses nor is there an option to filter for #ports like :80 & :443 to deal with restrictive #firewalls (i.e. on public #WiFi)…

  • there are flags like ipv6=yes but neither ipv4=yes nor ipv6=no yielded me other resultd than #IPv6 webtunnel bridges…

And before anyone asks: Yes, I do have a "legitimate purpose" as some of my contacts do need Bridges to get beyond a mandatory firewall and/or do use #TorBrowser (through an #SSH tunnel) to circumvent Tor & #VPN blocks and maintain privacy (as many companies do block sometimes entire #Hosters' ASNs due to rampant #scrapers

@shoppingtonz @alternativeto @torproject also every #Tunneling - regardless if #SSH or #VPN or whatever - will inevitably introduce #latency (unless you happen to be customer of a shitty #ISP with horrible #peering and thus can cut down on hops needed, which is AFAIK only a theoretical scenario)...

In fact I stopped using #HEnet #Tunnelbroker and #IPv6-#GIF-Tunneling because it created more issued than it solved on my #IPv4only #Internet connection…

Looking for real sets of hash-protected ssh ~/.ssh/known_hosts files/records, to tune cracking attack stacks on. The bigger the better.

Requirements: the cipher type and the fingerprint are not needed -- just need the hash and salt (first couple of base64 fields).

Individual cracks won't be published. If you want your own cracks, strong proof of ownership required. DM me!

@JessTheUnstill @Pibble

And yes, I treat all devices as insecure and would rather invest the time and effort needed get #TechIlliterates up to speed on the #OfflinePGP method!

Given the cheapness of storage (legitimate 1TB microSD cards exist and they ain't 4-digit items!) I'd legitimately look into #OTP #encryption and (IF I had the €€€€€€ to do so!) would even sponsor implementing it in #OpenVPN, #WireGuard and #OpenSSH (for #SSH-Tunmeling).

  • The #US is a #RogueNation with a Rogue Government! The sooner we accept this reality the sooner we can not only adjust to it but act accordingly…

I sincerely wish y'all could legitimately call me a tinfoilhat but so far I've been proven right all the time...

@Yuki @OS1337 @bjornsdottirs no need to go beyond 1440kB when using mlb instead of #syslinux (which wastes 200kB on it's own!)

  • Also including the #initramfs into the #Kernel can save more due to better compression than two seperate files.

Needless to say the core idea is to be a continuation of #tmsrtbt and a "minimalist #linux distro" as in "#SSH #Terminal #Firmware"...

If I have a #codeberg account set up, with a verified #ssh key on my account and the corresponding public and private keys in `~/.ssh/`, is there a way that I can make it so that it doesn't ask me for my keyphrase every time I push? I'm sure VSCode could do this, but since I've switched to #Helix, which doesn't have git built-in I've been manually doing the git stuff.
My knowledge of #cryptography and #git are well and truly at the 'barely enough to get myself into trouble' level.
