Spamhaus block
by Marc Lijour 27 Feb '19

27 Feb '19

Does anyone has insights about dealing with Spamhaus? I'm getting increasingly frustrated by being listed without explanation. I run a very low bandwidth mail server and a website for my business. I am running postfix with SPF, DKIM, and DMARC. I'd like to know what I am missing. Spamhaus is very popular which in turn affects Twitter, LInkedIn, beyond just the mail. Is it possible to run one's own mail server this days?

by Gary 27 Feb '19

27 Feb '19

I have kubuntu 18.04 with 20 gigs ram. Does anyone know what the optimum size swap area that I should have? Currently, my swap partition is 2 gigs. Can I increase that by creating a swap file in addition to the swap partition? /gary

Co-op Issues
by nick 23 Feb '19

23 Feb '19

Greetings All, I don't know if someone would be willing to give some advice on finding Co-op. For the last two semesters including semester I've been looking and found very little for my skills. Don't know what's up as literally getting in contact with folks at AMD got me contacts. Maybe someone has experience with the CO-OP program either hiring or otherwise. If someone wants a resume that's fine I would prefer to send it directly rather than to a public list through, Nic

Power over Ethernet question
by Russell Reiter 22 Feb '19

22 Feb '19

The Ontario Electrical Safety Authority has recently ratified Power over Ethernet for domestic residential LED lighting and associated home control systems. I was just wondering if anybody on the list is using PoE for lighting and has any recommendations on which types of LED's are best for general use. I have a 45w grow light for an African violet but the light it casts gives a kind of institutional feeling. I'm not sure I'd want it everywhere. I live in apartment with older ceiling fixtures and currently screw-in compact fluorescent bulbs last a year or so before the transformer dies from voltage spikes. Ostensibly this is from being on the same sub-panel as switched loads, fans, ac and the fridge being the main culprits. Any suggestions and anecdotes are appreciated. TIA Russell

IP mystery
by Darryl Moore 21 Feb '19

21 Feb '19

Hello LUGgers. Here is an interesting mystery for anyone interesting. I'd love if anyone could explain it. The following is cut and paste directly from my bash session and not edited in anyway. What the $*#$^ is going on here? I have reset all the routers between these two machines in case somehow they were responding to ARP requests instead of the target machine. I've done everything except for resetting the target itself. Also I have a daemon on the target which is doing 'C' system calls with getifaddrs(&ifap) library calls and it reports back both 192.168.11.50 and 192.168.11.133 even though ifconfig does not. Anybody have a clue what is going on here? cheers, Darryl ---------------------------------- darryl@darryl-Aspire-V3-575:~$ darryl@darryl-Aspire-V3-575:~$ darryl@darryl-Aspire-V3-575:~$ darryl@darryl-Aspire-V3-575:~$ ssh root(a)192.168.11.133 Warning: Permanently added '192.168.11.133' (ECDSA) to the list of known hosts.

FW: Problems with Ubuntu 18.10
by cdasilva＠iprimus.ca 19 Feb '19

19 Feb '19

Hello I am just resending this as I got ho responses Clive From: cdasilva(a)iprimus.ca <cdasilva(a)iprimus.ca> Sent: February 10, 2019 2:44 PM To: talk <talk-bounces(a)gtalug.org> Subject: Problems with Ubuntu 18.10 Hello I had a problem with my recent Ubuntu 18.10 install which I thought that I should share. I was running Ubuntu 18.04 on an older Pentium (R)Dual Core CPU E5200 with 4 gigs of ram and things went well. About 2 months ago, I noticed that there was an Ubuntu 18.10 so I thought that I would give it a try. So I downloaded Ubuntu 18.10 with kernel 4.18.0.10 and it worked well with all my machine learning stuff (Anaconda3, etc.). About 2 weeks ago, Ubuntu informed me that I had a kernel update so I downloaded the update (kernel 4.18.0.14) and tried to install it. Couldn't get past the boot screen, so I reinstalled 4.18.0.10 but right away I was informed of the waiting update. I googled the issue and the only comment that made sense was to block Wayland being loaded and instead default to Xorg by adjust custom.conf \etc\gdm3. That made no difference to my situation as described After about a week of tearing my hair, I gave up and went back to Ubuntu 18.04 LTS, and am just sharing this in the event that any of you have had a similar experience with Ubuntu 18.10 (in my case - desktop). Please feel free to comment -------------------- Clive Dasilva cdasilva(a)iprimus.ca <mailto:cdasilva@iprimus.ca> Ubuntu 18.04LTS

Intel Contact Info
by nick 13 Feb '19

13 Feb '19

Greetings All, I was wondering if anyone knows who to contact at Intel if possible at least in Toronto, the reason I'm asking is they don't have any email contacts to local branches on the site at least from my searching. As for the Hack Labs I have a also new Intel Galileo board if someone wants to take that off me. It's a gift that hasn't really see much use so it's probably better someone else has some fun with it. Or someone else can take it off of me if there interested. Nick P.S. I did email Chris and it seems that he does have contacts in Toronto so I will see what happens with that.
