Two questions. First of all, I clicked the Test button, and the top end of the traceroute that subsequently appeared contains traceroute to 58.167.97.145 (58.167.97.145), 30 hops max, 60 byte packets 1 c74c4c379cae16e810997134f5cc15c4 (5e2c247dafd7d7f56764b0aa191fc0f6) 0.194 ms 2 f6e356ef9aa666a92d5f60ea2bc5ea8e (169.254.236.30) 0.149 ms 3 0e59d32498246ca2e09f3633a00ac557 (d7a8206e439b4b3e3a1fc7748a81efc1) 0.383 ms 4 6fa566707dc34116d35780236ae52cf0 (6fa566707dc34116d35780236ae52cf0) 0.869 ms 5 5714851faaed656a09032ba1e48f02b0 (192.30.252.249) 1.319 ms 6 8-1-5.bear1.Washington111.Level3.net (4.15.136.21) 1.539 ms What are lines that don't contain IP addresses? That's really interesting. (Am I right to think this is a GH traceroute to me?) I'm also very curious what 7399:6CC8:00C3:75B09:59C19A46 is; I don't have IPv6... --- Secondly, I'm also idly curious why this always happens to me. $ git clone git@github.com:github/debug-repo /tmp/debug-repo-ssh Cloning into '/tmp/debug-repo-ssh'... Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. I don't have a local Git configuration (that I can find anywhere). I also don't have any sort of special SSH configuration. I generally use HTTPS for GitHub, but I was wondering if there was any particular reason I might want to use SSH for general use. (The one time I did want to actually `git push` something it took me a couple of double takes to figure out how to get it working. That was on a different machine than I'm on right now, though.)

My guess is that it's a md5 of the IP (with a salt) to hide what the actual IPs on their internal network is. But since they know the salt and the ip ranges they can find out what the IP is.

  After posting that I figured that's what was going on, yeah. That seems kind of scary though - I can easily brut--stops mid-sentence brb, finding out how fast my old i3 really is Edit: I drowned in the differences between md5 implementations. And all the "superfast" code I've found produces different results than stock /usr/bin/md5sum. So now I want to find an actually-fast and working md5sum implementation, and figure out why I'm getting different results. Yak shaving && stackdepth++ HN will likely lock this thread before I get to completing the above which is kinda sad, but email still works, I guess.
