Access to the new server(s)
by Tobias Pape 05 Apr '19

05 Apr '19

Dear all [ACTIONS AT END] with retroactive blessing of Levente, I have now prepared eight VMs on Rackspace. Here's the overview: ======================================================================================================================= Name Name (ext) intended use Unix Users Public Ports Private Ports Public IPv4 Private IPv4 ----------------------------------------------------------------------------------------------------------------------- ian ssh.squeak.org ssh-gateway ssh 1022 22 104.130.6.82 10.208.225.29 alan *.squeak.org webserver webteam 80, 443 22 104.239.229.92 10.176.200.8 adele lists.... mailinglists (tbd) 25, 587, 465 22, 8080 162.242.237.43 10.208.160.56 andreas -------- source.squeak chrismuller* -------- 22, 8080 irrelevant 10.208.161.222 dan -------- squeaksource davidlewis* -------- 22, 8080 irrelevant 10.176.197.150 ted -------- squeak wiki+map (tbd) -------- 22, 8080, 8081 irrelevant 10.176.130.111 david -------- jenkins (tbd) -------- 22, 8080 irrelevant 10.208.194.45 scott -------- misc (tbd) -------- 22, 8080, 8081 irrelevant 10.176.199.169 ======================================================================================================================= Currently, Levente and me have sudo on all these machines. Users with * also do. Note that _no_ server exposes SSH on port 22 on a public IP. This is intentional to narrow attack vectors for script kiddies. How to login? Ian is the ssh gateway so you have to connect to ian _first_ and use (1) local forwarding or (2) proxy jumping. I have installed the Public keys from most of you for the 'ssh' user on ian. Please verify by ssh -p1022 -lssh 104.130.6.82 you should see restrict shell, no commands # (you get out with crtl-d, ctrl-c, or killing ssh) How to reach the other servers? Example for 'andreas' variant (1): Do a local forward by ssh -AN -L22221:10.176.200.8:22 -p1022 -lssh 104.130.6.82 and then ssh -lYOURNAME -p22221 localhost (-N maybe optional, but then you see 'restrict shell, no commands #') Or in your .ssh/config you can put Host ian.squeak.org User ssh Hostname 104.130.6.82 Port 1022 LocalForward 222221 10.176.200.8:22 Host andreas.squeak.org User YOURNAME Hostname localhost Port 222221 And then say 'ssh -AN ian.squeak.org' and then 'ssh andreas.squeak.org' variant (2): (a) You have OpenSSH >= 7.3 Do a Jump with ssh -J ssh@104.130.6.82:1022 YOURNAME(a)10.176.200.8 Or in your .ssh/config you can put Host ian.squeak.org User ssh Hostname 104.130.6.82 Port 1022 Host andreas.squeak.org User YOURNAME Hostname 10.176.200.8 ProxyJump ian.squeak.org And then say 'ssh andreas.squeak.org' (b) You have OpenSSH >= 5.4 Do a Jump via ssh -o ProxyCommand="ssh -lssh -p1022 -W %h:%p 104.130.6.82" YOURNAME(a)10.176.200.8 Or in your .ssh/config you can put Host ian.squeak.org User ssh Hostname 104.130.6.82 Port 1022 Host andreas.squeak.org User YOURNAME Hostname 10.176.200.8 ProxyCommand ssh -W %h:%p ian.squeak.org And then say 'ssh andreas.squeak.org' (c) You have OpenSSH < 5.4 Use variant (1) We will shortly start RSYNC-ing over data from box3 and box4 as well as replicatiing DNS entries before switching over. [ACTION REQUIRED] - Who needs access to which servers? - Do we need Jenkins anymore? As always, questions appreciated. Best regards -Tobias

Voting Mailing List

HI all, Goran asked me if he could be taken off of the voters(a)squeak.org mailing list as the moderator. I don't believe I have access to the admin console on that list. Could you remove Goran and add me instead? Thanks! Ron Teitelbaum

squeaksource.com issues
by Levente Uzonyi 18 Jul '17

18 Jul '17

Hi All, squeaksource.com seems to be very slow from here (5-30 seconds response time, often 504). I think the image is running low of resources and keeps overdoing GC. Another issue I found is data corruption. If you have a look at the versions uploaded to the PostgresV3[1] repository, you'll find that some packages were uploaded by the user named ullrilad (squeaksource.com initials: ul). But that's neither true nor possible. It was me who uploaded the file using my own account (squeaksource.com initials: UL). This is read-only repository, so I presume some sort of data reconstruction algorithm incorrectly identified ullrilad as the uploader based on initials.
