Access to the new server(s)

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

squeaksource.com

Hi All, as you may know, squeaksource.com is down. I had a look and found that - the image had fallen into a GC cycle consuming 100% cpu and about 500 MB o memory - restarting the image didn't help with that - I added the -mmap 1024m parameter to its arguments, and it stopped the CPU grinding, and the memory usage has fallen below 500 MB since then. This also means that the VM's default memory limit is actually 500MB contrary to the 1GB stated by the VM. - but, the image is still not able to start up properly. it's probably stuck on something simple, but due to the lack of VNC, I just couldn't check what was wrong Levente

Mailing list problems
by Tobias Pape 08 Mar '17

Hi all, we got a “small” problem: Comcast/yahoo are pretty picky with regards to 'from:' in mails, so they reject mails from, eg, Gmail senders that are forwarded by us. SRS aprarently is not sufficient :( Result: more and more subscribers are being moderated (=receive no mails from us) due to bounces. Anyone got an idea? Best regards -Tobias
