WAN port on DD-WRT/Tomato will not get DHCP?

A few ways to solve, but I'm posting the cause in the hopes that it'll be easier to find.

The root cause is one of two things: One, the cable modem/provider taking a snap of the first MAC address and essentially refusing to provide DHCP to other devices after that, or Two, the method of acquiring DHCP causes the device to become blacklisted by the DHCP server.

I'm ruling out #2 in my case because once I spoofed the MAC of my PC (the first item I connected) and then disconnected the PC/power cycled devices - the router immediately got DHCP.

Anyways, the actual cause might just be a 'first device gets DHCP', in the sense that the vast majority of consumers will either connect a wireless router, or a single device - not a dumb switch like I did to increase my options.

To verify this, I powered everything off, plugged the cable modem LAN direct into the router's WAN port

My provider is TekSavvy, the cable modem is a Thomson DCM476, the router is a WRT54GLv1.1 on Tomato 1.28 (also tried both versions of DD-WRT), for reference.  Yeah, I'm still on B/G.  It's like the black and white television of wireless router technology.

    Hi, I think you need to reinstall the firmware of the router. It seems to me that this is a bug. Try it should all run like clockwork. Guide here http://www.routerstop.com/tomato-router-setup/, if needed. Good luck to you, if it does not solve the problem, write to me, I am very interested to solve this problem.

Learning through failure - a keyboard creation journey

Image
tl;dr Built a custom keyboard cuz I have weirdo nerve pain issues.   Learned a lot cuz I failed a lot.   Maybe 'do it right the first time' is a bad frame of mind.   The keyboard ended up being kinda nifty.   It has lights, and a trackball, and QMK, and it helps my issues.   \o/ ( tl;dr is internet lingo that means, too long; didn't read ) Pain as a key ingredient An old proverb says, 'necessity is the mother of invention', and that is how this story begins. Over the last few years, age or stress or something has caught up with me and I developed the need to change my human-to-computer interface.  Mousing changed to trackballing.  The traditional keyboard was swapped out for an ergonomic, and then split keyboard.  Complicated multi-finger-and-hand key combinations were replaced by single keypress macros.  And yet more was still needed. It's often said that change only happens with pain - indeed, the organizations many...

Learning Opportunities - Watching/listening list

Over the last year I've spent a lot of time learning (thank you, long commute & lunch hours).  Many topics ranging from Chef to DevOps to architecture concepts to management concepts and everything in between.  Why have I done this? DevOps Demystified with Ben Rockwood: https://www.youtube.com/watch?v=h5E--QSBVBY DevOps at ancestry.com: https://www.youtube.com/watch?v=pF5ya0q53kk Those two presentations were key in sending me down this road.  First, and most important, was Mr. Rockwood's explanation as to the real 'why', and the point behind DevOps from an operational perspective.  Second, and no less important but for a different reason, the continuous delivery system at ancestry.com really made it real to me because they are a 'Windows shop'.  So much of what I'd been reading about Chef/config mgmt. relied on amazing tools (see the error there?) only available to the Linux world.  Suddenly here's this guy telling me that it's possible...

DFSR - eventid 4312 - replication just won't work

This warning isn't documented that well on the googles, so here's some google fodder: You are trying to set up replication for a DFS folder (no existing replication) Source server is 2008R2, 'branch office' server is 2012R2 (I'm moving all our infra to 2012R2) You have no issues getting replication configured You see the DFSR folders get created on the other end, but nothing stages Finally you get EventID 4312: The DFS Replication service failed to get folder information when walking the file system on a journal wrap or loss recovery due to repeated sharing violations encountered on a folder. The service cannot replicate the folder and files in that folder until the sharing violation is resolved.    Additional Information:  Folder: F:\Users$\user.name\Desktop\Random Folder Name\  Replicated Folder Root: F:\Users$  File ID: {00000000-0000-0000-0000-000000000000}-v0  Replicated Folder Name: Users  Replicated Folder ID: 33F0449D...
