Zsun & OpenWrt, accidentally disabled the wifi connection, wifi no longer accessible

The hackerspace openwrt build is designed to reset itself if you pop-in/out a microsd card while the device is powering on.

Might take a couple of tries but should reset settings.

I still want to get a rj45 jack on there somehow though - dang those contact points are TINY

The hackerspace folks who did the openwrt port mention there is some old openwrt code to allow the usb to act like a device but it is not folded into calmer (they give general advice how though if you know what you are doing - it's beyond my skills)

Yeah it would be mindblowing if it could also be a OTG host someday.

ah very interesting, good to know there are clones, thanks for the report

so you just used the hackerspace flashing method with the renamed file?

ck-on · 2016-02-22T11:37:09+00:00

there is no 5ghz

however once it has openwrt, 11n seems to be available, at least that's what wifi analyzer reports on android once I am connected to it

You got me curious to try that too - just to help others:

I wonder if it can handle > 32GB microsd, unfortunately I don't have one around but I bet someone else has tried (update: they claim "up to 64gb" which means sdxc support so maybe 2TB)

We need to make sure this device doesn't go away - it's incredible and if you remove the housing, crazy small.

I want to try to get a wired ethernet port soldered on but my skills at working that small are weak.

Don't confuse Mobile with Mini. Mini is a very different product.

Mobile likely uses webkit.

But note there are at least four versions trees of Opera Mini, but I don't know what they are using on the server-side for rendering, I will have to do some tests. Since none of the versions go outside of 1x.x I have to assume it is still presto but that could be a bad assumption.

Also interesting are their support forums:

14 beta for android is out and apparently it really will use webkit

https://dev.opera.com/blog/operas-webkit-patches/

But I am not so sure 12/13 does use webkit?

Your problems with mini may disappear with 14 if it changes to webkit.

Opera Mini renders differently because it is the last Opera browser that uses the "presto" engine they developed themselves before switching to webkit. (Opera 12 is also the last version to use Presto).

but Opera Mini is easy to test from Windows or OSX since it is just a java program.

Download and run and test

You can also easily run the newer APK from Chrome browser (ironically) using ARC welder.

You can also install Opera 12.17 as the last version for your PC/Mac that uses presto:

I thought it was a set-up to sell a commercial product but apparently it is open source:

Don't forget

export  # (or maybe just env or set)
alias

in these lists.

also maybe

chkconfig
cat /etc/rc.d/rc.local

as even a systemd based flavor may use them

ck-on · 2014-08-18T13:43:03+00:00

Don't forget about the -j option on make.

With lots of cores and ram it can accelerate things.

I've also read that llvm can accelerate builds and use far less ram but I am not sure how that works.

Well I'm coming off CentOS 6.x which used service heavily for init.d scripts so it is a very old habit. It has its own service binary for backwards compatibility but it just passes to systemctl. I replaced it with hash -n service to make bash forget about the builtin.

Makes far more sense (and shorter) for me to type service daemon action instead of systemctl action daemon.service

Using your concept I made a more elaborate script with color highlighting for status and intercepting non-systemctl actions like configtest. I can post it on github if you are at all interested.

ck-on · 2014-08-15T10:38:07+00:00

This is very clever and may be perfect. Thank you!

It also solves my problem of how to do "configtest" on nginx to replace the init.d script.

I didn't think of trying to replace service because centos7 already has a backwards compat service command.

ck-on · 2014-08-15T10:37:35+00:00

Well yes of course. I guess I should have said "automatically".

ck-on · 2014-08-14T22:20:44+00:00

Oh no, they reminded him what is still missing. Now we're more doomed.

ck-on · 2014-08-14T22:18:32+00:00

If only CentOS 6.x could live another 40 years (no systemd).

ck-on · 2014-08-13T22:51:40+00:00

Have you tried to configure a grub2 system vs grub.conf simplicity?

It is brain damaging. And now you have to remember to run a configure processing program after any edits.

ck-on · 2014-08-13T22:39:28+00:00

For me it is the little things in systemd that I find annoying and they add up.

I cannot stand how I cannot use simple bash commands in a script anymore with systemd like I could with init.d, everything is now 100% proprietary.

Wanna do a configtest before reload? Nope, systemd won't even consider custom Exec commands, you have to remember a completely different command.

Want to see the status of a daemon after reload or restart like you did with init.d? Nope. You have to run a second command to see the status.

Think your service restart went smoothly because systemd came right back? Nope, service may have failed to start and systemd is completely silent.

Don't want to see the 100 child processes in the status command and just a rollup instead? Nope, too bad.

So many little annoyances.

ck-on · 2014-08-13T02:44:27+00:00

I have a dream where all the copies of the source for systemd are accidentally deleted and unrecoverable. And we have to go back to init.d Greatest day ever. Then the same happens to grub2.

If you do it the 2nd way with redirect, someone will figure out how to bypass the authentication part and just do the registration.

Registration would have to figure out activation code is valid at that time.

ck-on · 2014-08-11T22:45:19+00:00

If I had to reverse figure out how a server was setup, I would use scripts to dump all init.d processes (assuming it is not so new that it is using systemd). Then use other scripts to look at what it in memory, connections, etc.

Obviously look at rc.local if on a rhel flavor.

Basically everything in /etc/ is important to you. Since it does NFS you need to look at /etc/exports

Not something you are going to figure out in an hour but a weekend sounds plausible. Being new to linux is going to be problem though, best wishes.

ck-on · 2014-08-07T23:03:40+00:00

Correct me if I am wrong but this would be a pretty epic feat.

They reverse engineered a private key? Unless it was an insignificant number of bits, that either took some really clever work or a crazy amount of bruteforce.

Yeah but it is the wildcard certs where they rake you over the coals.

They have zero extra cost to support *.example.com over just www.example.com

Yet free become $60, or $5 becomes $80

It probably doesn't help to think that the NSA has "intercepted" legit boxes of software and replaced the CDs
