MTS blocking NTP
by Trevor Cordes 27 Jan '19

27 Jan '19

I noticed that at one of the customers I have that uses low-end business MTS has had their NTP incoming/outgoing port (UDP 123) cut off (filtered) at the ISP. Incoming I can understand, but outgoing? All the computers in the office have their time out of sync now. Does anyone know what the internal Bell/MTS time server's IP/domain is? Surely they didn't cut us off to their internal one. Will have the customer contact them eventually, but you know how it goes with tech support. Looking for the quick solution... Anyone else have their UDP 123 cut off since Bell came along? Further: it looks like they are filtering outgoing only if your source port is also 123. That is hardcoded into ntp (from what I've read). But ntpdate allows the -u option to have the src port be >1024. I tried that and ntpdate -u does work, but ntpdate without the -u gets blocked. So they really are blocking in and out, but only src=123udp. Looks like chrony (and others) lets you specify src port, but I'm loathe to uproot the system I know because Bell is braindead. (MTS didn't use to block it, and block-happy Shaw does not block it.)

Is anyone here using Ryzen (1 or 2, or derivatives) with Linux? (ECC irrelevant, fyi.)

Jan 8 meeting - ethernet cards
by Adam Thompson 03 Jan '19

Assuming I make it to the meeting at all (here’s hoping), I expect to have four dual-port E1000 NICs to give away; two are PCI-E and two are PCI-X. Oh, and if anyone needs IDE/ATA cables, please let me know – I’ve got more here than I know what to do with, and would LOVE to send them to a good home. -Adam
