Subdomain wildcard in Bind-style DNS editing
by Hartmut W Sager 24 Jul '24

24 Jul '24

I have a question about subdomain wildcards in Bind-style DNS editing, so that I can more conveniently edit DNS zone files to implement Fastmail's support of MX records specifying "*.mydomain.com." for e-mail at subdomains. (Yes, Fastmail's documentation states their support for this.) Now, in Bind-style DNS, we have valid short notations for full FQDN in the name field (the left side) as follows: "@" = "mydomain.com." "abc" = "abc.mydomain.com." So my question is, might the following also be valid? "*" = "*.mydomain.com." "*.@" = "*.mydomain.com." Hartmut

RHEL latest package?
by Trevor Cordes 20 Jul '24

20 Jul '24

I finally gained access to the documentation for RHEL for a dedicated-hosting RHEL server I work on. But I find it hard to figure out where to go in there to find much of anything. And google doesn't seem to index what it is I need, maybe because of the paywall? I'm trying to figure out 2 things: 1. How can I tell what is the latest rpm/version RH has put out for httpd? I'm talking stock RHEL-supplied, not IUS/EPEL or whatever 3rd party. I know in Fedora this would be simple with bodhi/koji and/or simple rpmfind. 2. How can I tell if my RHEL box is setup to receive updates? Dnf works to install packages, but no updates seem to be coming across? I'm a bit worried because of the recent not-so-great apache/httpd bugs. I know RH has all this subscription stuff I normally don't have to mess with with Fedora, and I like to think the dedicated hoster set this all up properly, but I'm not sure how to tell. Thanks!

dialog(1) shell fd acrobatics question
by Adam Thompson 08 Jul '24

08 Jul '24

I’m trying to debug a shell script that uses dialog(1), which has the unfortunate habit of overwriting the debug output I wanted to see. After quite some time banging my head against the wall, I grabbed the source to dialog to look at their examples. Their examples follow a pattern I have NOT been following; I’m now looking at this trying to understand WTF it does: 1 exec 3>&1 2 returntext=`$DIALOG --title "RANGE BOX" --rangebox "Please set the volume..." 0 60 0 123 5 2>&1 1>&3` 3 returncode=$? 4 exec 3>&- so… ok. Line 1 duplicates FD 1 (stdout) into FD 3. That’s usually so we can mess with FD 1 later on and still have a handle to stdout. Good so far. Line 2 runs /usr/bin/dialog in a subshell, the options to dialog(1) are irrelevant here. I’m looking at the redirects. “2>&1” duplicates FD 1 into FD 2, effectively throwing away the handle to the inherited /dev/stderr and forcing stderr output onto stdout. That’s a good thing because dialog(1) reports its results onto stderr by default to avoid messing with curses(3) output. “1>&3” however, throws away stdout (FD 1), replacing it with FD 3 which is… already a copy of FD 1 ??? Line 3 is obvious. Line 4 closes FD 3. Not sure that we need to bother, but OK, cleaning up behind ourselves is usually a good thing. I get the need for swapping stdin/stderr, as dialog(1) – well, really curses(3) - uses stdout to paint the screen, so dialog(1) spits its results out on stderr to avoid conflicting. If we’re in a subshell trying to capture that output, we need to grab it just as dialog(1) exits – and $() assignment only captures stdout. But what’s the point of having FD 3 in this setup, if all we do is assign it to stdin inside the subshell and then forget about it? Can anyone see what I’m missing here? -Adam

I'm back!
by Brian Lowe 16 Jun '24

16 Jun '24

Hi everyone, TL;DR: My email was down for a week while I migrated to a new provider. I've been using valuehost.ca to host groupbcl.ca's mail for over a decade now. On June 3 they sent me an invoice for service renewal just 3 days before expiration. The only payment option was credit card via PayPal. When I attempted to pay, PayPal demanded a mobile phone number in addition to billing address information, which in my opinion is unnecessary for a simple credit card transaction. As far as I'm concerned, a mobile number is the 2020s version of the SIN/SSN: a unique identifier that can be used to link disparate accounts together. I simply do not trust PayPal to use that information solely for the purposes of this one transaction. I opened a support ticket on June 6 requesting alternate payment methods. There was no response for over 40 hours, despite a follow-up I posted nearly 34 hours later. On June 8 my account was suspended for non-payment, despite a ticket being open on this matter with their billing department for a day and a half. (The only thing to Valuehost's credit in this entire affair was they waited two days past the invoice due date before suspending my account.) That cut off my groupbcl.ca email address, which I've been using for over 20 years for most of my email correspondence. I updated the ticket 7 hours after my follow-up, requesting to be billed only for the domain renewal and not the hosting package. They replied 2 hours later stating that my domain is not registered with then (which was true) and had marked my hosting as cancelled. This was the only time they made any sort of comment on the ticket. Seven hours later I replied to the ticket, noting my email was now down and requesting options to get it going again. They never responded to that note. Late in the day on June 10 I sent a letter of complaint to the only other contact Valuehost has on their site, hoping that would get someone's attention. They never replied; not even a pro forma message indicating they received my email. By the evening of June 12 I had given up on Valuehost and signed up for mail hosting with HostPapa, who accepted my credit card without any problems. I had to provide them with a phone number, but because they're in Canada they're subject to PIPEDA. After updating my MX record, I spent a fair bit of time getting the HostPapa account to show test messages I sent them from my ISP's email. I had problems getting KMail talking to HostPapa. Their documentation for Thunderbird says to use port 995 (pop3s) with TLS for receiving and 465 (smtps) for sending, but when I duplicated the settings in KMail it failed on both. Eventually I configured KMail to connect to port 25 using STARTTLS for receiving and to localhost for sending, both of which worked. I then configured my postfix server to relay outbound mail via HostPapa's mail server. On June 13 I updated the ticket at Valuehost to say I had migrated to a different provider, and closed it. Unsurprisingly, I'm very disappointed in Valuehost's almost complete lack of action to my ticket and will no longer do business with them. Brian

Hi all, I'm thinking of getting a Mikrotik hEX router for light OpenVPN service. Is this a good choice? Are there better ones? Where would you recommend buying one?

Fizz (and Freedom) Mobile cell phone plans are now available in Manitoba
by Bradford Vokey 06 Jun '24

06 Jun '24

As I mentioned during this month's MUUG round table meeting: I have recently switched 2 of my family's mobile cell phone lines to Fizz Mobile and I am loving them so far! fizz.ca Cell Phone Plans in Manitoba | Fizz <#> Discover Fizz customizable mobile plans for Manitoba. Adapt yours based on your needs and budget. Plus, you get rewards on day 1. 🔗 https://fizz.ca/en/mobile/manitoba?ADDONS[0]=18&CVRG=108&DATA=231&PLAN=1&SM… <https://fizz.ca/en/mobile/manitoba?ADDONS[0]=18&CVRG=108&DATA=231&PLAN=1&SM…> I had mentioned that Quebecor was delaying bringing their Freedom Mobile brand to Manitoba (in favour of launching their own Fizz Mobile brand here first), but it looks like I missed their official new Freedom launch! Quebecor has now officially launched their Freedom mobile brand (which they acquired from Shaw during the recent Rogers/Shaw merger) to Manitoba as of May 23, 2024! https://www.freedommobile.ca/en-CA/article-freedom-manitoba "At launch Freedom is offering customers in Manitoba a deep discount on its 10GB Canada-U.S. mobile plan which is available for $14.50 per month ($29 reg.) for six months." You can view the Freedom plans for Manitoba here: www.freedommobile.ca Cell Phone Plans Winnipeg (Manitoba) | Freedom Mobile <#> Discover Freedom Mobile's cell phone plans in Winnipeg, Manitoba. 🔗 https://www.freedommobile.ca/en-CA/manitoba/plans <https://www.freedommobile.ca/en-CA/manitoba/plans> I still think their Fizz Mobile brand offers greater flexibility with: - data rollover, - data gifting, - generous perks (like free unlimited data days and additional free data every month), - the ability to change your plan every month to fit exactly what you need, - and it has slightly lower overall prices for <= 10 GB data plans. But you can't go wrong with either company compared to what the big 3 (Bell, Rogers, and Telus) are charging us here in Manitoba. *If you do decide that you want to try Fizz Mobile, don't forget to use my referral code "16KPK" to get a $25 credit (for both you and me!) during your second month of membership.* If anyone has any questions about my experience with Fizz, just ask away. It worked flawlessly in the US during my recent trip to Huntsville, Alabama and I haven't had any issues with it in the Winnipeg area so far. -- Bradford C. Vokey Treasurer Manitoba UNIX User Group
