I think I've got a pretty good in as a sysadmin at a particular factory in the area. Turns out a guy I work with has a wife who found a new job in another state. The job she is vacating happens to be the position I've applied to and she's going to drop my name to HR, so here's hoping.

I've got a freelance project for a local business to do a massive infrastructure overhaul and they're paying me very well for the work. Enough to last me several months, so I've got a window, at least.

So I work at a school in a larger campus, independent of our central IT which obviously manages the infrastructure among other things.

My boss apparently left word that I was to hook up an ASUS Wifi router, which, as there's no way he told our networking people about it, would effectively be a rogue AP that would easily be traced back to me, as I'd have to whitelist the MAC address to hook it up.

I am not going to do this thing. I'm going to go home instead.

Just got in to the network of a sister company that is being decommissioned, we're gutting the infrastructure, bringing it to our site, and only keeping the core services online for future access.

Their EMC navisphere web interface has no password, wide open on the network. :stonk:

So flipping the switch to On turns on a totally unconfigurable STP instance, and since the switch is so old there's a chance it wants to be the root bridge. What could possibly go wrong?

That's a ridiculously big broadcast domain, right?

I'm one of those "working on my CCNA" types and I'm just wondering if my initial reaction was right.

That's aside from the weirdly short lease time. ...which would further exacerbate any issues caused by the broadcast domain, since the machines would be broadcasting for DHCP more often, right?

Yeah, /16 is an insanely large amount of address space, so much so the average business could probably turn lease time to max and never run out .

Hey, guys, me again with some more slightly less pesky DSL questions. :-)

If Google is any measure, I am apparently the ONLY PERSON IN THE WORLD doing ADSL RFC1483 bridging to the wired switchports AND doing NAT/DHCP with the built-in AP at the same time on a Cisco 877W. Having spent the better part of THREE DAYS poring over literally thousands of pages of Cisco's documentation, sample configurations and endless threads on help forums, I have finally replaced and consolidated my ancient Cisco 678 and a no-name crappy wifi router. I'm online again and life is unicorns and glitter and unbridled glee.

I'll mostly spare you the long and highly entertaining post-mortem of the eye-pokingly arduous installation and just say that the last time I dealt with IOS in any meaningful way was dual-homing a 3745 with Verio and ELI in the [LOCATION], around 2003. Renaming, renumbering and physically reorganizing an entire domain of Unix servers, load balancers, switch cluster and desktop clients in about a day was a walk in the park compared to bending that bloody 877 to my will. Then, as now, a Unix guy working with IOS, it makes me feel like smashing my own skull in with hammers. You can only admire Cisco's dogged determination to keep IOS as murderously frustrating and willfully obtuse as ever after all these decades. But it works, and I expect it will continue to work as long as I never have to touch it again. :-) (My 3548XL switch has been up for 7 years, 41 weeks without a reboot. I guess sometimes you really do get what you pay for. Like quality UPS batteries, obviously. :-)

I am wondering, though, if you guys might take a quick peek at the status of my DSL port on your end and make sure nothing is terribly amiss... I hope I didn't spam your logs with all the bouncing up and down of my circuit over the weekend... here's what the new modem, with much better firmware than the vintage 678, reports:

DSL: Training log buffer capability is not enabled


At first glance it looks like the error counts are lower than on the older modem, but I'm not sure if they report the same things the same way and that's after only a couple of days of uptime. Because I've had this same line since 1998, and USWest/Qwest/CenturyLink has done *nothing* to maintain, update or improve service on the POTS side since the Reagan administration, can you tell me if the noise, power and attenuation numbers look okay? I'm fewer than 4 city blocks away from the [LOCATION] CO, so less than 1,000 ft of copper between here and there.

Also, curiously, the new modem seems to lock in the 7168kbps download speed without difficulty, whereas the 678 would sometimes struggle to maintain full rate; on the other hand, this one seems to refuse to train the upload side at any rate above 640k. Uh, has CenturyLink screwed with my provisioning? That should be a wee bit closer to 896k, should it not? The "capacity used" percentages imply that maybe there's a little more headroom available for upload... would it help if I changed "dsl operating-mode auto" to something better matched to the Redback on your end?

mc-gw(config-if)#dsl operating-mode ?
adsl2 ITU G.992.3 Annex A and L
adsl2+ ITU G.992.5 Annex A
ansi-dmt ANSI T1.413
auto auto detect mode
itu-dmt ITU G.992.1 Annex A

The 678 always seemed to negotiate (or was fixed at) ANSI T1.413, but the 877W's default is to try ITU first. That's a simple config option easily reversed without locking in a particular mode, assuming you guys prefer to let things negotiate rather than hardwire the settings. Will ANSI mode perhaps give me a titch higher upload rate? I suppose I could just bo... whoops. I suppose I could _schedule_ a time to bounce the interface and see if there's a difference? Don't want to be experimenting though if it'll impact other customers in 69.30.73/24 or making weird alarm bells go off on your management consoles. :-)

Any hints or feedback would be appreciated, and thanks again for taking the time to humor an old dinosaur,

I tried to explain how it's generally a good idea to stay on your infrastructure group's good side and that, while I wouldn't get fired over it, I could very easily have my rights to our InfoBlox (necessary to whitelist devices so that they can receive DHCP addresses) revoked.
