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

Reboot required but I don't feel like it.

Hi all, just fyi, the servers need to be rebooted somewhen (kernel updates) but frankly, I don't feel like it. :D Best regards -Tobias

Re: [Box-Admins] [Board] Rackspace OSS discount ends at the end of the year

Adding the box-admins list. On Tue, Sep 12, 2017 at 03:50:19PM +0200, Bert Freudenberg wrote: > Oh @#$%. > An excellent concise summary. A few initial thoughts from my point of view. We should: 1) Make sure we have backups, and ability to recover from the backups, for all the services. 2) Determine our actual Rackspace costs, beginning January 2018, if we no longer have the "discount", and if we continue to operate in our current server configuration. I think that the costs are in the neighborhood of $2000 - $3000 (US dollars) annually for our current server configuration, but we should confirm the actual numbers. 3) Figure out what the minimal Rackspace costs will be if we migrate services to a smaller number of servers on Rackspace, and shut down the unneeded servers to minimize billing costs. For example, I could migrate the squeaksource.com service to another box on Rackspace, and turn off the billing for dan.box.squeak.org. I think we are using eight virtual servers now because it is easy and it is "free", but maybe we only really need one or two or three. 4) Make a plan for life after Rackspace. Or maybe with Rackspace, if they are still in the low cost virtual server business. Dave p.s. Tim Cook can sell a smart phone for $1000. So what's up with the pricing strategy on our Squeak swag? I am a happy owner of a genuine SQLogo coffee mug, but I rarely brag about it to my friends, because it only cost me about $15. This mug is truly an aspirational product. If I had been allowed to spend^h^h^h^h^hinvest $100 on this mug, I would be proud as a peacock and the extra revenue could have funded another virtual server or two. ;-) > > On Tue, Sep 12, 2017 at 3:46 PM, Brett Smith <brett(a)sfconservancy.org> > wrote: > > > Hi everyone, > > > > I have good news and bad news for you today, so I???ll start with the bad > > news.

INFO: blocked by Microsoft

Dear all our mailserver is being blocked by mircosoft (live/outlook.com etc.) for sending from a rackspace IP range that is allegedly known for spamming. I asked for removal but that didn't work, apparently. I have no intention to fix that, too much effort, to be frank. best regards -Tobias > Begin forwarded message: > > From: mailman(a)lists.squeakfoundation.org > Subject: Bounce action notification > Date: 20.

In your example, the current theme was not touched and is still active. That is, your environment as an active theme that is not in the list "UserInterfaceTheme allThemes".

A place for Scratch

Hi folks, please could you make a place on files.squeak.org where I can put a release of NuScratch ? Since it’s 5.1 based I suppose one might argue it should go under the 5.1 branch but I really don’t mind much. Thanks tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim USER ERROR: replace user and press any key to continue.
