HUAWEI Router tries to manipulate HTTPS connections?

At home I use a HUAWEI Router (Huawei B528s-23a), the default device which my provider recommends.

In last days I got often a certificate error when opening a website which was obviously not the routers page.

In Safari for example:

Safari: certificate is not trusted

It’s seems that the router answers the SSL-Connection instead of the page I wanted to open. Is there any explanation for this strange behaviour?

ps: I’m not a native English speaker; Please forgive for my potentially mistakes.

If my computer system is on, but none of my network connections are active, can someone work on hacking into my OS?

I thought I read that if my network connections, both wifi/ethernet, are NOT on, that if someone wanted to try and work on hacking my OS, that they would have to wait until the network connection is active, even if my computer and everything connected to it is powered on (firewall, switch, router, etc).

How do I connect to WPA2 Enterprise wireless networks on 18.04 without breaking regular wireless connections?

I’m running 18.04 and need to connect my laptop to a WPA2 Enterprise network at my school that I’m fairly sure uses MSCHAPV2 with PEAP and no CA certificate. When I connect with the credentials that work fine with Windows and on my iPhone, it fails to authenticate as if my password is wrong. I’ve tried adding my ID to anonymous ID, which failed. I’ve tried no PEAP as well as a couple other security types, no dice. I’ve seen some old solutions but they seem to break compatibility with regular wpa2 networks, which is a deal breaker for me as I need seamless switching to my home network. Compounding my issues, I don’t have access to gnome settings as I run the deepin desktop. lshw shows my wireless card as being an Intel Dual-Band Wireless AC 3168NGW [Stone Peak], whatever that means. Any help is welcome!

How to deliberately slow internet connection to better understand UX on slower connections?

I would like to better understand UX on slower connections.

Is there a set of tools or instructions on how to achieve this on mac/windows?

FYI my software isn’t a website or app, it’s desktop software that runs on mac and windows.

Perhaps there are tools available to help? (I don’t mind a DIY solution though)

Identification of Unknown Potential MITM/Malware involving SSL Connections

On my server one of the services is a Discord bot. It was down which prompted me to look into why.

In my syslogs I noticed three increasingly concerning items:

do-agent[1066]: 2019/08/25 08:50:21  Sending metrics to DigitalOcean: Post https://sfo2.sonar.digitalocean.com/v1/metrics/droplet_id:  x509: certificate is valid for *.com.com, com.com, not sfo2.sonar.digitalocean.com  discord-botd[26673]: 2019/08/25 09:03:50 [DG0] wsapi.go:827:reconnect() error reconnecting to gateway, Get https://discordapp.com/api/v6/gateway:  x509: certificate is valid for *.com.com, com.com,  not discordapp.com  discord-botd[26673]: 2019/08/25 09:04:59 [DG0] wsapi.go:827:reconnect() error reconnecting to gateway,  x509: certificate is valid for www.chinanetcenter.com, oir.6rooms.com, upload.v.6.cn, pic.v.6.cn, uploadmp3.v.6.cn, *.1z123.com, ulink.6.cn,  passport.6.cn, shrek.6.cn, www.huanpeng.com, img.huanpeng.com, mlog.chinanetcenter.com, mauth.chinanetcenter.com, i.g-fox.cn, s1.chunboimg.com, s2.chunboimg.com, s3.chunboimg.com, sstatic.chunboimg.com, s0.chunboimg.com, app.showcai.com.cn, auth.microfun.cn, ss.sysad.cn, ss.sysair.cn, sso.kongzhong.com, stc2.kongzhong.com, passport.kongzhong.com, auth-live.kongzhong.com, api.kongzhong.com, i.zhulang.com, m.zhulang.com, s.zhulang.com, app5.zhulang.com, www.cmyynet.com, start.crestdrop.net, load.ginamind.com, fast.sireech.com, play.homesava.net,  qfcnc.calaprilia.net, mobcdn.znoopbag.net, start88.trackeast.com, play88.trackeast.net, amengsk.haitangbase.net, *.1zhe.com, res.samsungshop.com.cn, mobcdn.clerkin.net, h5cont.trueleffy.net, marsara.nidajudo.com, *.app.meitudata.com, *.meitu.com, *.meipai.com, *.meitubase.com, *.img4399.com, *.converse.com.cn, apk-ssl.tancdn.com, m.wywna.cn, media-qtil.licdn.com, media-exp1.licdn.com, media-exp2.licdn.com, media-exp3.licdn.com, media.licdn.com, platform-qtil.linkedin.com, platform.linkedin.com, static-qtil.licdn.com, static-exp1.licdn.com, static-exp2.licdn.com, static-exp3.licdn.com, static.licdn.com, m.staff.tcl.com, *.ourdvsss.com, cdn.zj96596.com, addons.cdn.mozilla.net, *.tcl.com, *.mall.tcl.com, www.17un.com, m.li0gx.cn, korhal8.clerkin.net, start88.nidajudo.com, usercenter-stage.ewfresh.com, pay-stage.ewfresh.com, mall-stage.ewfresh.com, order-stage.ewfresh.com, settle-stage.ewfresh.com, m.leinue.cn, m.aonanp.cn, m.nbuic.cn, m.xrhen.cn, m.zosue.cn, m.bustz.cn, m.yuwxe.cn, m.bxuwg.cn, m.ykdsbsc.cn, m.rushour.cn, m.nlpzzd.cn, *.xunsd.cn, m.mmgdfr.cn, m.kigoxhz.cn, m.xxqysj.cn, m.mmzdjq.cn, m.ybwbmk.cn, *.zhangyixun.cn, m.i2d1kc.cn, m.hr00.cn, m.ubmhu.cn, fsdext.fshares.com, fscant.fshares.com, www.fshares.io, fscan.fshares.io, fsdex.fshares.io, manage.fsdex.fshares.io, api.fshares.io, dex.api.fshares.io, manage.dex.api.fshares.io, chain.api.fshares.io, manage.chain.api.fshares.io, jpa.api.fshares.io, jpa.node.fshares.io, hka.api.fshares.io, hka.node.fshares.io, fs.fshares.io, guide.fshares.io, browser.api.fshares.io, wallet.api.fshares.io, wss.api.fshares.io, wss.dex.api.fshares.io, back.dex.api.fshares.io, back.chain.api.fshares.io, gate.dex.api.fshares.io, *.sg2046.cn,  not gateway.discord.gg 

After a reboot this went away.

openssl s_client -showcerts -connect <url> showed nothing unusual (though I wish I had done this before a reboot).

Some background:

  • Server is an up-to-date Fedora 28 server.
  • The non-default services that I run are:
    • a Golang based webserver (HTTP REST API)
    • a Golang based Discord bot
    • Digital Ocean’s stats agent
  • SSH is password-less and firewall restricted to certain IP addresses.

I haven’t run into this before nor am I able to find similar results on google.

Is it possible to identify how this happened or if it is even of concern?

Should I nuke the server?

Thanks!

hardware airplane switch on supposedly causing wireless connections to not work

I have been having this issue when I updated to linux ubuntu 19.04 on my very old Dell latitude D830, one error I’ve been having is the internet connection not working, because wifi doesnt connect. I’ve tried every solution in here so far with NONE changing anything.

My original problem is that tge internet connection, wifi, is disabled, and it says UNAVAILABLE, tryinf to enable it doesnt work. I cant use tethering or usb or bluetooth because the only way I get internet is wifi and those options turn it off from my phone.

output of sudo rfkill list:

Again, every other solution i saw over here by googling didnt work, I typed more than a million commands for this problem to go, I actually encountered it earlier when i installed ubuntu 19.04, but I fixed it, but then after that by some months, i think around 2/3, it came back. and I have no way whatsoever to fix it, i even tried going back to what originally fixed it.

Multiple arduino connections problem

I have 2 arduino mega 2560 connected via USB to my Ubuntu 18.04 machine. When I boot one connects to /dev/ttyACM0 and the other connects to /dev/ttyACM1. Communication works perfectly. However, randomly on boot the arduino boards connect to the opposite the port then what is coded into the script. I use python 3.6 to communicate. Is there any way to force these boards to always connect to the same port? Or is there a way python can detect the board its talking to?
