Re: [GTALUG] TekSavvy or Rogers blocking apt user agent
I've seen this before on a fortigate firewall. The FW will detect "apt" as app:XMLRPC rather than app:HTTP for the purposes of "Application Detection" and if the "allow port 80 rules" is infact an "Allow only app:HTTP on port 80" rule , then XMLRPC over port 80 is disallowed.

If you told us the how, we might have more faith that you wouldn't do it again. But more and more, technical support departments are hiding these outcomes - either to disguise what they think could be regarded as incompetence or because they're afraid it might reveal secrets about their processes or infrastructure. Both have some validity. Having been in the position myself [1], I get that it's not appealing to reveal the process and problems discovered, but I'm still a believer in transparency. [1] I'm in "Operations," here's just one example. We upgraded Debian on a back end server which in turn broke Chrome 49 - but it took over a week to figure out that HAProxy was the reason for the Chrome 49 breakage. We then upgraded HAProxy again (to Debian backports) which fixed Chrome 49. Yes, we still have to support that. And this has led to a big dispute at work about whether we should be notifying people and on what level of upgrade ... You get the idea. -- Giles https://www.gilesorr.com/ giles...@gmail.com --- Post to this mailing list talk@gtalug.org Unsubscribe from this mailing list https://gtalug.org/mailman/listinfo/talk

Yours works better: mine fails on the double slash '//' because it insists on looking for a non-slash item right after it and so produces '/a/.b///1' when it should have given me '/a/.b//c/1' as yours did. It's somewhat academic as in processing prompts the regex should never encounter two slashes with nothing between them, but ... I prefer the more correct answer.
