OpenWRT on WNDR3800 home router - my install thoughts

by joel d

Decided to try OpenWRT after Jim Getty's talk and strong recommendation last month for improved security and reduced local buffer bloat. What follows is my experience / thoughts from this process. I would happily bring the hardware to demo at a future meeting if there is interest. Likely wouldn't be a full meeting but a 10-15 minute filler. More likely Q&A than anything else. I decided to go with different router/firewall hardware so I bought a Netgear WNDR3800 which Jim mentioned and is also a favorite of the OpenWRT crowd. Mine was used and $50 shipped from e-bay. This model is one model old and no longer available new. FYI: Netgear website lists it as "out of support". My WNDR3800 was used prior, so I needed to do a hard firmware reset on the bottom of router with a paperclip (didn't know the prior IP used or the admin password). Once reset and rebooted, router worked fine and could login to the "default" Netgear firmware and configuration. Default username & password is printed under the router. Downloaded the recommended OpenWRT firmware for this model. Needs to be full "factory" (instead of partial upgrade) and squashfs is recommended. Netgear WNDR3800 Firmware download link gets you OpenWRT version 10.X version which is not latest OpenWRT. Web browser login to Netgear webpage/firmware and followed "upgrade firmware" link while pointing to OpenWRT download file on local disk. The upgrade/re-flash took around 4 minutes and after a reboot worked fine. Set password and reconfigured router and WIFI with my specifics. Was up and working on OpenWRT v 10.x. Next day realized I had OpenWRT, but not latest stable version. Upgrade firmware link does not go to Internet directly, so first download OpenWRT v 12.4 with "upgrade" and "squashfs" and save to local disk. Second apply this via upgrade button in OpenWRT web link. I could likely have saved a step by grabbing the OpenWRT v12.4 for WNDR3800 with factory and squashfs. I bet this would have worked had I tried it (and saved a step). General thoughts after use for a week: OpenWRT does not have an "update direct to mother ship" feature best I can tell that downloads file and updates it from web interface. Not a show stopper for me. Instead need to know your version of OpenWRT and download an "upgrade" file and apply as two steps. This would only matter if router was used/maintained by a non-geek. Prior problem occurred with similar hardware WNDR3700 with latest Netgear firmware (happened with prior Linksys also). A few embedded WIFI devices in home would disconnect and fail randomly and at least weekly. Thus far these device annoyances have not occured since swap to WNDR3800 and OpenWRT. No idea why, but definitely A win! OpenWRT has transmit power level settings for the WIFI radio transmit. Can decide to bump up the WIFI radio settings if user chooses. Even if you melt/destroy them, a cool option if needed & tested. Firmware update for OpenWRT works from a laptop on WIFI, which in my experience Netgear & Linksys and other vendors do not support flash without a cabled ethernet port. So the OpenWRT update scripts the 1) copy file 2) apply file 3) reboot device. My Next Steps: In another week will likely repurpose the WNDR3700 likely as a WIFI gateway for the "cheap WIFI radio" devices, (mainly TV, roku, DVD, etc.). Not yet sure if I will use OpenWRT for this. Look into the option of external antennas for the WNDR3800. I live out in the country and have few neighbors to notice/know/care. If I can get there... improved & reliable WIFI signal at my mailbox would rock.

With Fedora Core 3 there have been vast improvements in the area of hardware hotplugging, detection, and configuration integrated with the desktop. There is still more work to do, but it is getting better all the time. I'm not aware specifically of which USB adapters work best.

Re: Improving WLUG outreach

by Dennis Payne

The NatickFOSS group uses gettogether.community instead of meetup.com. I don't know that it has gotten us any visibility but the software is open source. I've been tempted to join meetup to go to Boston Indie Game Developer meetings but have so far held off. The NatickFOSS group also gets a booth at the Science on State Street event at Framingham State. It is a free STEM activity fair for kids. My job at the event is to generally occupy the time of the kids so the other members talk to the parents. First year I had a playstation controller hooked up to my laptop and held it out to any kid that walked by. Last year I brought the arcade machine assembled by my son's cub scout den. Any idea if WPI does any thing similar? Even if it is something only for WPI students it might be useful to alert people to the group's existence. -- Dennis Payne dulsi(a)identicalsoftware.com https://social.freegamedev.net/channel/dulsi

Followup [Re: Follow-Up to Key Signing Party]

by Jamie Guinan

Ok, so I did, gpg --recv-keys ... [everyone's ID from the meeting ] gpg --fingerprint ... [ confirm fingerprints ] for key in ... ; do gpg --sign-key $key; done for key in ... ; do gpg --send-key $key; done Now "gpg --list-keys" shows all the keys I expected to see. And just now I did a "gpg --recv-keys <my ID>" and it said I had 6 new signatures, gpg: requesting key 103BA0B0 from hkp server pgp.mit.edu gpg: key 103BA0B0: "Jamie Guinan <guinan(a)bluebutton.com>" 6 new signatures gpg: 3 marginal(s) needed, 1 complete(s) needed, PGP trust model gpg: depth: 0 valid: 1 signed: 12 trust: 0-, 0q, 0n, 0m, 0f, 1u gpg: depth: 1 valid: 12 signed: 1 trust: 12-, 0q, 0n, 0m, 0f, 0u gpg: next trustdb check due at 2009-04-16 gpg: Total number processed: 1 gpg: new signatures: 6 I think that looks good. At some point I'll look into using it for email and other things, but at least the basics are there. -Jamie

Yes food and drink are allowed. The class room has lots of plugs along the walls, although bringing out some extra power strips can also happen. We support back to Cambrian era, so Mezozoic is no problem ;). Precambrian however you are going to need to bring your own microscope.

Re: Reminder: WLUG Meeting tonight: Topic ProxMox / Turning Pi 2

by soup

Yep, definitely the case. Need CUDA cores, without them it's doing other and more work. It's funny the apple silicon will probably see faster performance increase than the Radeons just because that's where the people wrenching on this stuff are. I'm still in intel land there for OSX and will be for quite a while (audio software reasons). I'm operating slowly with a 2070RTX and agree, once you've got process, it is a much better value proposition to pay for cloud inferencing. Merging of large checkpoints, building intricate models, aren't possible on consumer hardware until you get into silly money and datacenter boards will always be faster in any case. There's facility and process for separation of elements but were I working professionally in this fashion I would not be expecting final output from inferencing. I would use it as a stock library, at this point in the tech anyway. Even the simplest use of the thing- generating backgrounds, saves so much work and allows for so much different _kind_ of work that if that was all it did it would be a revolution. Separation or direction of elements during inferencing has seen improvement in leaps and bounds, though. Not long ago it was just inpainting (creating masks), and autogeneration of partitions with math, then partition by token/attention and now even automatable manipulation of masking and weights by partition by mask. So it's definitely doable but would require each to build pipeline for their needs. Those tools are still in early stages but the ComfyUI¹ has a 'workflows' conceit for doing a lot of that with visual programming. I haven't moved on from grado library webui yet so no first hand experience with it. Already have pipelines for my purpose in that, the usual, no time to move to the bleeding edge~ For that particular need, the stock featureset of Automatic1111² can do growth, called "outpainting", of a given input. There's extensions to expand on steering capabilities for that but it does a fine job in my experience, as long as the checkpoint and tokens you're using "knows" something of the input. Talking about art is like dancing about architecture so I hope I'm being clear. Also, I should say this is all down at the consumer level, folks building huge base models or using it in enterprise are much more likely to be using pytorch and the diffusers lib. soup ¹ https://github.com/comfyanonymous/ComfyUI ² https://github.com/AUTOMATIC1111/stable-diffusion-webui On Thu, Feb 15, 2024 at 9:52 AM John Stoffel <john(a)stoffel.org> wrote: > > You have to have a recent nVidia CPU to get good results, I was trying > using AMD GPUs and it just wasn't fast at all.

Carlton> I've done software RAID (RAID0 and RAID5) for a long time and Carlton> never had to use an initrd image.

Currently, I don't have that.

Carlton> As far as RAID1 and RAID5, isn't RAID5 strictly better, if Carlton> you have the HD's? I mean, just lose 1/3 of the storage for Carlton> total mirroring and you have to lose 2 HD's to lose your Carlton> data. Why would someone choose RAID1 over RAID5 (just Carlton> curious)? I did have a RAID5 system set up, but decided to Carlton> change it over to RAID0 and use an external Maxtor drive for Carlton> backup (just simple rsync). RAID0 = stripping RAID1 = mirroring RAID5 = parity RAID5 suffers on write performance when compared to RAID1, since if you write a small chunk of data, RAID5 may have to actually READ/COMPUTE PARITY/WRITE to all the drives. With RAID1, it's a simple parallel write to each drive. No READ overhead. RAID5 can generally just lose 1 disk from the set without losing data. RAID1 can lose 1/2 the mirror without losing data. How you implement your RAID1 setup across more than two disks is an issue. I choose RAID1 over RAID5 because I only had space for two drives, and I only had an HPT302 with dual channels, so I put one disk on each channel for maximum peformance. If I had more money and a 3ware controller, I probably would have gone for RAID5 on my data, since it has a size/cost advantage over RAID1. I would NEVER go for RAID0 for my data, too much potential for data loss. Even with backups. Carlton> Personally, I feel if you compile a couple of kernels it Carlton> really becomes old hat, I mean, once you know how to do it Carlton> it's no big deal. Same with RAID systems. But that would be Carlton> an interesting meeting, nonetheless. Exactly, it would be an interesting meeting to show people how easy it is to implement, and hopefully how robust it is as well, esp if you lose your primary harddisk.

What are the benefits of using it? >From what I know, the advantage/requirement of using an initrd is that you can boot off of a funky device, since you first boot into a small OS image with all the tools you need to setup and switch to your main filesystems. In my case, I've got a pair of 9gb SCSI disks, and I currently boot off one. My plan has always been to mirror the two disks so that if I lost one, I could still boot. My data is all on a pair of 120gb IDE drives, which are mirrored, and which have saved me from ugly restores, because I noticed that one disk had dropped out and I was able to just re-mirror without any major impact.
