good deal on tiny Dell desktop
by D. Hugh Redelmeier 16 Sep '20

16 Sep '20

<https://forums.redflagdeals.com/dell-dell-precision-3240-compact-workstatio…> I bought one of these. - save $200 by opting for Ubuntu rather that Windows 10 Pro! Okay, I admit it: I only saved $100 by not selecting Windows 10 Home. - very small: limited expansion and performance. - business class (well built, stodgy, well supported (3 yr. warranty)) It is a real adventure game finding and stacking all the discounts. Well described in the article. Read the whole thing, but 95% is in the first page. - Join Rakuten Canada (formerly called ebates) and go through their site to get 8% cash back on Dell for Business purchases (don't be fooled by the more prominent 2% regular Dell cash back offer). - join the Dell mailing list for a one-time 10% discount code. If you are on the mailing list already, it appears you can join again with the "+" in the username trick (i.e. mail to joe+anything(a)example.com should go to joe(a)example.com) - the article lists a stackable $50 off coupon Configuring the system is interesting. Key: choose a cheap HDD and add a third-party NVMe SSD drive after you get the machine. Choose 8G single-stick of RAM. Add more after you get the machine (one SODIMM slot will be empty). I chose an Intel WiFi/BlueTooth card. That gets the chassis wired for an antenna.

odd connector for parallel printer port
by D. Hugh Redelmeier 10 Sep '20

10 Sep '20

I just noticed that the latest printer that we bought (Brother HO-L5000D) came with an odd cable (matching an odd connector on the printer). On one end, there was the conventional-since-the-IBM-PC DB25M connector. On the other end, there was a 3-row, 26-pin mail D connector. I don't remember seeing this connector before. When did this get invented? I don't think that I've noticed it before. (Parallel ports for printers are pretty much replaced by USB these days. I do have antique computers that are pre-USB but I don't print from them.) Why did this get invented? Was this to prevent serial/parallel confusion? I do remember being annoyed at IBM selecting the DB25 instead of using the industry-standard "Centronics" connector because serial and parallel could so easily get mixed up. I will probably save the cable forever. I'll probably never use it. If I need to, I'll probably be unable to find where I've stored it.

Due to confusion, our Jitsi server isn't up right now, and our Usual Suspects for Zoom addresses haven't responded yet... However, hopefully the following zoom address https://zoom.us/j/6476576575 may function enough to get us going... -- When confronted by a difficult problem, solve it by reducing it to the question, "How would the Lone Ranger handle this?"

Updating my mailserver
by William Witteman 01 Sep '20

01 Sep '20

I have run a mailserver for my domains for a long time. I have not thought about its ability to send outbound mail for a while though, and my logs tell me what my experience already suggested - it cannot send email to Gmail (and probably lots of other places). Can anyone recommend a tutorial for setting up my mailserver (I'm using postfix on Debian) so that Gmail and others will accept my mails? I am pretty sure there is reverse DNS that I don't have set up, but there are probably other details I don't know about too. Thanks!

Generic SSH question.
by Alvin Starr 31 Aug '20

31 Aug '20

Does anybody know of a software package or service that does for SSH the kind of thing that teamviewer does? I run into linux systems that are behind firewalls and trying to bounce through some windows box using teamviewer or other screen sharing app is getting real old. -- Alvin Starr || land: (647)478-6285 Netvel Inc. || Cell: (416)806-0133 alvin(a)netvel.net ||

for multi-hop ssh/scp: option "ProxyJump"
by D. Hugh Redelmeier 31 Aug '20

31 Aug '20

I'm away from home, regularly accessing my computers at home. Easy: ssh into a gateway machine and ssh from there into the internal machine of my choice. Nested ssh sessions. It gets a little more annoying when I want to transfer a file. The new-to-me ssh/scp option "ProxyJump" handles this conveniently. Consider the example of transferring a file "f" from machine "home" through machine "gw" to machine "away", all done from an xterm on "away". Note: because "away" is behind NAT, "gw" cannot scp to it. Note: -A enables ssh-agent to avoid some manual authentication Note: things become more complicated if f has slashes. [away] $ ssh -A gw [gw] $ scp -p home:f . [gw] $ exit [away] $ scp -p gw:f . [away] $ ssh -A gw [gw] $ rm f [gw] $ exit This can be simplified because the ssh command allows shell commands as arguments. That's not a habit I've developed. [away] $ ssh -A gw scp -p home:f . [away] $ scp -p gw:f . [away] $ ssh -A gw rm f The ProxyJump option makes this a lot simpler: [away] $ scp -p -o 'ProxyJump gw' home:f . I have no need for more than one intermediate hop so I haven't figured out how that would work.
