rehab a yard bike derailleur return spring/pivots - Lemmy.World
I’m cleaning-up a $30 garage sale bike. The derailleur is lazy, and not
returning to gear 1 without a little help. I’ve put WD40 on the pivot pins and
moved it through full range of motion by hand a couple hundred times. Wondering
if anybody has any easy methods. I feel like I should put it in a coffee can of
light oil, but wired to a door, so every time the door opens/shuts, that works
the derailleur pivots :) . Or something.

point-of-sale $4k credit still working? - Lemmy.World
I was wondering if the $4K(USA) used EV tax credit was still getting applied at
USA auto dealers. It sounds like the credit still applies until September 30th,
but I haven’t heard if the IRS/dealer website and database are still working.
dot1dTpFdbPort returns strange ifIndexes

dot1dTpFdbPort returns strange ifIndexes - Lemmy.World
Cisco catalyst 9k Trying to use SNMP to build a list of MACs on ports. Using
dot1dTpFdbPort, I am getting index numbers which don’t match anything I can see
e.g. these MACs are on ports 527, 525, 523: -
SNMPv2-SMI::mib-2.17.4.3.1.2.0.31.146.1.21.47 = INTEGER: 527 -
SNMPv2-SMI::mib-2.17.4.3.1.2.0.31.146.1.21.48 = INTEGER: 525 -
SNMPv2-SMI::mib-2.17.4.3.1.2.0.31.146.1.21.49 = INTEGER: 523 …and MACs in hex: -
myswitch:527 00:1f:92:01:15:2f
- myswitch:525 00:1f:92:01:15:30
- myswitch:523 00:1f:92:01:15:31
… The physical ports are: - 2020 001f.9201.1531 DYNAMIC Gi6/0/43 - 2020
001f.9201.1530 DYNAMIC Gi6/0/45 - 2020 001f.9201.152f DYNAMIC Gi6/0/47 ifIndexes
of those ports are: - IF-MIB::ifName.315 = STRING: Gi6/0/43 - IF-MIB::ifName.317
= STRING: Gi6/0/45 - IF-MIB::ifName.319 = STRING: Gi6/0/47 The ifIndex table
doesn’t even go up into the 500s. I’m guessing there is a jump table somewhere
to cross-reference FIB ifindex to PHY ifindex?
enterprise wifi auth and 47-day TLS certs

enterprise wifi auth and 47-day TLS certs - Lemmy.World
Has anybody heard if the upcoming 47-day maximum on TLS cert lifetime will apply
to Enterprise wifi auth using private PKI (especally on IOS and Android)? We
have a campus CA that signs the TLS cert used by RADIUS when students connect.
Freshman need to accept the cert once (hopefully after checking the
fingerprint), then usually never again before graduation.
setting needle bar height - Lemmy.World
I’m blowing the cobwebs out of my mom’s 1986 Ward’s (Happy Sewing Co) machine. I
have been watching videos of setting timing: >adjust timing until the hook
passes through the scarf… …and how to set the needle bar: >adjust needle bar
height until the hook passes through the scarf… (I’m paraphrasing) It sounds
like you could take a perfect machine, then lower the needle bar 1mm, then
compensate by delaying the hook 30 degrees, and you’d have the hook passing
through the scarf at the correct spot… yet it would be all wrong. Is there a way
to set needle-bar height independent of the hook timing? Like, obviously the
needle needs to rise a few millimeters to make the slack thread form into a loop
behind the scarf, ready to be caught by the hook. Is that amount of rise
kinda-sorta consistent across machines from a given era?
