I'm having trouble getting connected to my TP-Link Deco 5 WiFi mesh network from Mint Cinnamon. I can connect to my other WiFi networks and am able to connect to the mesh network from any of my other devices, I'm only having problems with Mint and the mesh network. I appreciate any help you guys can give, I've Googled and tried several things but, nothing has worked.

[lubuntu] 18.04 LTS x64: for approx. a minute after boot, cannot connect to server on same LAN

September 16, 2019, 1:09 pm

I'm reasonably new to Lubuntu, I've been using it since June last year (the same version the whole time). I have a server on my own network that hosts my mail and websites. I have Thunderbird to check for mail. No problems until the last couple of weeks I'd say, then I started noticing in the mornings that Thunderbird could complain of the connection being refused to two mail accounts hosted on my server even though it could connect to say my gmail accounts during the same startup mail accounts check.

Today I looked into it a bit more thoroughly. My first check was to see whether the issue was limited to TB. It wasn't: If I telnet'd to the mail server's mail port, it would time out. Repeated attempts would time out for a minute or two then inexplicably it would be able to connect.

This evening I booted Lubuntu, left it on the login screen (without logging in at all) for about 30 minutes then signed in: same problem.

dmesg has this at the end of the output:
Code:
[  130.354226] [UFW BLOCK] IN=eno1 OUT= MAC=01:00:5e:00:00:01:1c:74:0d:7a:be:08:08:00 SRC=192.168.0.1 DST=224.0.0.1 LEN=36 TOS=0x00 PREC=0x00 TTL=1 ID=0 DF PROTO=2
But then it commonly has that in the output even when I haven't had this kind of problem, and I've had the firewall enabled for at least a year.
Side note: I'd like to know what that entry is actually trying to tell me.

I tried another test: Log out then back in again: No problem.

I'm pretty sure the problem isn't intermittent: Cold boot or reboot, sign in, problem occurs.

[all variants] Monitoring network traffic by process/program name

I've been searching for a tool that does it and couldn't find any yet.

I'm using YAmon on my OpenWRT router, with it I'm able to monitor internet traffic for each device on my LAN. It happens that 99% of my traffic comes from my Ubuntu server, as I have Transmission and CrashPlan on it.

I'm looking then to a tool to run on this server, that allows me to monitor traffic by program (full path) name. If possible, include too parameter it received when executed, as they all run as daemon.

I'd need to exclude inbound and outbound connections on LAN, as this server does a lot of traffic with my NAS too.

Could anybody suggest me? Or is it that hard to monitor traffic by process?

[server] IPv6 ordered allocation & Dynamic Hosting

September 17, 2019, 1:02 am

Hello friends,

I have a complex situation here, to which I partly found a solution, but let's just say I want to view all the possible angles, so I am asking for your opinions, so this e-mail is a looooong e-mail, so bare with me :)

I want to ask only experts to help me ! Please ! If you are unsure of what is being said here, please do not try to offer solutions.
I want help of professionals, who _DO_ understand these things. Thank you !

So, here goes:

I have a Linux router&services server (PC) at my home. This PC runs Linux (Ubuntu Server) and routes my Internet access and also hosts websites, e-mail, VPN, and so on...

My ISP provides Fiber connection with PPPoE connection, Dynamic IP address, up to 1 Gb/s bandwidth. It also provides dual-stack IPv4 and IPv6 and Prefix Delegation.

Having said this, the following scenario occurs:

1. IPv4:
--------
My ISP provides me 1 public IPv4 address which is Dynamic, so it changes at every new connection (powerloss, intentional disconnect, server restart, and so on...)
Naturally, behind the Server (Router) I will use Private Addresses (192.168...) and Iptables->NAT->Masquerade them to the current Public IPv4 of the PPP Interface (ppp0) or whatever is called, when I successfully dial-out.
I would have used SNAT, but for SNAT I need a fix IP address. So I use MASQUERADE.
(Q0: Is it possible to SNAT to a dynamic IP address ? to spare MASQUERADE an extra lookup of the dynamic ip on ppp0)

So no problem here, so far.


2. IPv6:
--------
Here is a little bit of problem, as my ISP provides Prefix Delegation with a dynamic class.
Let's call this example class: "2001:db8:a:b::/64".

Q1: Upon connecting with "pon isp" (pppoeconf), how does my IPv4 and IPv6 addresses get assigned to my PPP interface ? Is there some internal mechanism or using DHCP ?

Also, my ISP provides the prefix delegation, so that every IPv6-enabled device on my internal LAN will try to get the Prefix Delegation and try to form its own IPv6 address using EUI-64 Mechanism. (Stateless (SLAAC)).

Q2: I want to use an ORDERED Ip address assignment mechanism. So, instead of "2001:db8:a:b:1234:12FF:FE34:5678" (SLAAC generated address), I want the following:
"2001:db8:a:b::1/64", "2001:db8:a:b::2/64", "2001:db8:a:b::3/64".
So, similar to "192.168.0.1", "192.168.0.2", "192.168.0.3", I want to ORDERLY assign addresses, but using the dynamic prefix given by my ISP.

So, if the ISP changes the class to: "2001:db8:a0:b1::/64" for example, I want to be able to address my devices like this: "2001:db8:a0:b1::1/64", "2001:db8:a0:b1::2/64" and so on...

So, regardless of what dynamic IP (IPv4) and Class (IPv6) I obtain from my ISP, on my local side I want to use fixed addresses (In IPv4 is easy by using fixed private addresses, but in IPv6 I don't know how to allocate fix host-side addresses)


I hope I made myself clear until now :)
Okay, let's say I resolve the addressing part. Every device has it's private IPv4 address (using MAC-based DHCP) and every device has it's IPv6 address derived from the dynamic network part and the stable host part, so everything is OK, we go to the next chapter:


3. Dynamic DNS Hosting:
-----------------------
My server also hosts some websites, e-mail, vpn and so on...
Yeah, I know, having a Dynamic IP does not really help the hosting business... :(
And no, I do not want to pay twice (double price) for my Internet subscription to get a static IP, both IPv4 and IPv6....

My ISP offers me a Dynamic DNS service on-the-fly, without software clients needed, but only for their dynamic IPv4 address assigned. They left out IPv6 :(

So, I need to get a real dynamic DNS service which operates on both IPv4 and IPv6.

I heard of some major players in this field: dynu.com, he.net, dyndns, afraid.org, no-ip, etc...

Q3: Which is your recommendation, what experience do you have with the above DDNS providers ? Which one is the best ? The best meaning instant update of new addresses, the lowest possible TTL for lowest possible downtimes.

P.S. I do NOT want to host my DNS zone at some other provider. I have my own BIND DNS Server so I want to personally host my domains. I only want a FREE DDNS HOSTNAME acting as an intermediary between my dynamic IPs and my domains.


4. Technical workaround to avoid CNAME. DNS records for dynamic IP:
-------------------------------------------------------------------
To describe the technical path a DNS query takes is beyond the scope of this thread.
Simply put: I have some domains. At my registrar, I declare the nameservers for those domains as being the free dynamic dns host.

For example, I register "username" at the "ddns.provider" (which can be any of the above providers) and I get a hostname "username.ddns.provider" which automatically points to my Dynamic IPs (both IPv4 and IPv6) and it gets instantly updated with my IPs via a software client called "ddclient" or some other means....

How can I instruct my BIND DNS Server to update A & AAAA records automatically with the new addresses of the PPP0 interface ?

I want a BIND configuration similar to the below one (a very simplified example):

"
SOA {...}
NS username.ddns.provider
MX 10 mail.domain.suffix
domain.suffix IN A {PPP0_IPv4ADDR}
domain.suffix IN AAAA {PPP0_IPv6ADDR}
mail.domain.suffix IN A {PPP0_IPv4ADDR}
mail.domain.suffix IN AAAA {PPP0_IPv6ADDR}
"

I do NOT want to use CNAME. I know that the easy way is to use like this:

"
domain IN CNAME username.ddns.provider
"

But this causes extra recursive lookups and may cause some problem with MX and Mail Hosting.

I want to update the Zone file automatically with the current IPs of the PPP0 interface (both Ipv4 and Ipv6) so that the client recieves a clear A or AAAA record to connet to further down the road, and no CNAME (aliases) are involved.

Q4: How can I do that ? :) How can I bridge somehow the "pppoe" and BIND to update my zones with the new IPs from ppp0 interface ?


5. Reverse DNS & Outbound mails:
--------------------------------
Yeah, this is a tough one...
I am afraid that my ISP does not offer me a custom reverse DNS for my IPs as my IPs are changing constantly...

Do you know of other methods to secure or improve my e-mail server in order for my mail to get delivered corectly ?

Blacklisting the ISP IP range is not so common these days because my ISP blocks port 25 and only allows it based on a formal request by a client.

DNSSEC doesn't seem to help, SPF records, domainkeys ?... I only want to be able to send e-mails from my server (using ISP dynamic IPs) and get delivered corectly.


So, basically, these are my concerns.

Please, if anyone can help, offer some suggestions, it would be greatly appreciated !

[all variants] Getting 1GB/s ethernet over powerline connectors

September 17, 2019, 11:26 am

My router and motherboard support 1gb/s connections and I've just checked I'm using CAT5e cables out of my computer and into a TP link powerline adapter (like this: https://www.tp-link.com/uk/home-netw...tl-pa4010-kit/ ), and from the adapter the other end into the router. This connection is running at 100Mb/s.
I note from the text of the hyperlink that it says 100MBps on the manufacturer's website, but then the photo of the box clearly says 600MBps and the model number is AV600. When I changed the connection speed manually by editing the network settings for "Wired Connection 1" to 1Gbps it wouldn't connect, so my quest is to discover the reason why it wouldn't connect as I don't know much about these powerline adapters; my two queries:

1. Is 600Mbps even a possible connection speed - i.e. does it have to be the discrete 10/100/1000MBps rather than the obscure 600Mbps?
2. If 1) is "yes, it is possible", has anyone achieved 1Gbps or anything > 100Mbps with these powerline adapters?
3. If 1 and 2 are "yes", does anyone know if this particular model will do 600Mbps?

Any help or guidance appreciated.

[ubuntu] Clustering two ubuntu servers

Hi,

I have very CPU intensive tasks that take forever and I would like to spread the tasks among several machines. I read about Beowulf, but it seems there is little activity or new posts for "Ubuntu Beowulf". Is there some Ubuntu package to offload some of CPU intensive tasks to another server? Most of the tasks are executed from shell, so for now I am torturing rsh, but there must be better ways to do it.

Does anyone know of an easy to install package that would allow me to offload some of shell executed commands to another Ubuntu server?

Thank you!

Wifi Adaptor Dongle Drivers 8198 Realtek Semiconductor Corp.RTL8187B (FokTech AC600)

Hello!

I have a wifi dongle from Amazon (see link: https://www.amazon.co.uk/Foktech-802.../dp/B06XZ5B5G9) and wondered if it could be made to work with ubuntu.

I am running xubuntu 18.04.

I know it is not working as I am unable to get a wifi signal from a distance that was possible while on a windows system.

lsusb returns this:

Bus 002 Device 003: ID 0bda:c811 Realtek Semiconductor Corp.

Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

I have had a little look around and while I have a very vague idea of what to look for it seems there isn't much visible support for this hardware on linux.

I saw in amazon comments for this product that someone had managed to get it working. Here's that comment:

"It does not work out of the box - driver software needs to be installed. This can be fiddly to make it work so don't buy if you are looking for something that plugs in and works. The box includes a CD-ROM with Linux driver software, which did not work for me [I bought this a while ago so can't recall it coming with a disk]. The following commands worked for me on Mint 18.2 which is based on Ubuntu 16.04:

$ sudo apt install linux-headers-generic build-essential git
$ cd software-builds
$ git clone https://github.com/abperiasamy/rtl8812AU_8821AU_linux
$ cd rtl8812AU_8821AU_linux
$ make
$ sudo make install
$ sudo modprobe rtl8812au "

I followed these command instructions, but got stuck on "cd software-builds" as the directory was not present in my home folders. I gave my disk a quick search to see if the directory was present elsewhere, but it returned no results. I then decided to create the software-build folder in the home directory and continue the instructions. It seemed to progress smoothly with no errors but after I got the the end the adaptor still didn't work or appear on "sudo lshw -c network". I restarted the computer, and once I confirmed it wasn't working I ran that commands again: still nothing. Was there anything I was supposed to do after reaching the end of the instructions? Was I supposed to put the "software-builds" folder in a specific place? Are these instructions unlikely to work to begin with?

Thanks for all your help in advance.

[xubuntu] trying to get DNS caching working right

at this point i am unable to get the "unbound" DNS caching server to run. it ran when it was first installed but after a reboot it would never start up. it is complaining about an invalid key for the control port.

i hear that systemd has a resolver, but it seems to be missing on my system while the rest of systemd is running. systemd is just all too confusing.

all this came about because 2 programs were ignoring the /etc/resolv.conf file (which directed queries to 3 particular IP addresses offsite) and sending queries to 127.0.0.1. so the idea has been to get a DNS cache running that would listen on 127.0.0.1 (only) and forward all queries to any of the IP addresses i configure it to forward to. local caching is fine, but i do not want it to directly do recursive resolving. it must send all DNS queries to one of those addresses.

i was just reading about dnsmasq. i does DHCP and TFTP, too. but i could not find how to turn those off. i do not want either of those to be run, just DNS caching and forwarding only.

a program that does just DNS forwarding and (optionally) caching, only, would be great. high performance is not needed.

is there anyone around that knows about today's DNS software? or do i need to accept local resolving and run BIND? also, does anyone know why ntpd ignores /etc/resolv.conf?

hi guys,

same problem as everyone regarding realtek drivers, i've updated the kernel and wifi stop working.

Wireless-info.txt: https://pastebin.com/j9b64ufp

i tried to compile the driver from github but some concepts are new to me, like "blacklist" a module (how to do it?) and possible symbolic link error that could lead to "modprobe: error: could not insert 'r8822be': exec format error".

can someone please help me to figure out?

my actual status now is: i have rtlwifi_new compiled and (i supposed) installed in my system, i'm booting insecure (to running non-official modules, right?), but i really don't know if i handled modprobe correctly (the Wirelless-info shows rtl8822be module, not r8822be)..

ps: my smartphone can see a wi-fi hotspot created by notebook, but can't login.

best regards,

Hi, I installed the new version of ubuntu (18.04) in an external hard drive and I run it in my macbook pro 2018.
Since the installation I wasn't able to connect to internet (I authenticated myself and it looped, my credentials were okay, but the connection was never established, and also the wifi bars appear to be very weak) and so i've been trying in different forums to fix this, but I've come to a point in which not even the wifi icon appears.
I didn't had the wl, when I used modprobe it returned FATAL error, but I was able to include it and excecute the modprobe command.
I found a wireless script and I executed it, I'm attaching it hoping someone can help me with this issue.

[ubuntu_budgie] Wifi hardware not supported by kernal

Have a 2019 Dell XPS 15 that has a Killer 1650 Wireless-AC adapter. Running with Ubuntu Budgie 19.04, the kernel does not support his adapter and I need to build it manually and copy to the /lib/firmware/ folder.

I would assume that the 2019 XPS 13 that Dell sells with Ubuntu installed has the same driver. So, why doesn't the kernel support this wifi hardware?

Need IPTABLES rules explanation about OpenVPN set up

Hello!
I've got Ubuntu 16.04 and OpenVPN installed and seems to be working fine. But when I check firewall rules using "sudo ufw status", then I see this:

Code:

Port 1194 isn't mentioned at all! But I use netstat command "root@mail:~# netstat -anlp |grep 1194" I get this:

Code:
udp        0      0 0.0.0.0:1194            0.0.0.0:*                          1142/openvpn
Also I have this file, created by the OpenVPN script here /etc/systemd/system/openvpn-iptables.service and I see this in it:

Code:
[Unit]
Before=network.target
[Service]
Type=oneshot
ExecStart=/sbin/iptables -t nat -A POSTROUTING -s 10.8.0.0/24 ! -d 10.8.0.0/24 -j SNAT --to xx.249.16.253
ExecStart=/sbin/iptables -I INPUT -p udp --dport 1194 -j ACCEPT
ExecStart=/sbin/iptables -I FORWARD -s 10.8.0.0/24 -j ACCEPT
ExecStart=/sbin/iptables -I FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT
ExecStop=/sbin/iptables -t nat -D POSTROUTING -s 10.8.0.0/24 ! -d 10.8.0.0/24 -j SNAT --to xx.249.16.253
ExecStop=/sbin/iptables -D INPUT -p udp --dport 1194 -j ACCEPT
ExecStop=/sbin/iptables -D FORWARD -s 10.8.0.0/24 -j ACCEPT
ExecStop=/sbin/iptables -D FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT
RemainAfterExit=yes
[Install]
WantedBy=multi-user.target

So my question is... if port 1194 is open (is it?) with these IPTABLES rules, then why I don't see it in ufw status?

[ubuntu_mate] NetworkManager does not spoof MAC address after making appropriate configuration

September 20, 2019, 12:52 am
$

not a duplicate, I believe this problem is unique to my system, possibly a configuration issue or missed syntax or step, etc., or perhaps an unreported bug... but I'm uncertain.

I've followed this guide https://wiki.archlinux.org/index.php..._randomization and ​https://blogs.gnome.org/thaller/2016/08/26/mac-address-spoofing-in-networkmanager-1-4-0/ ...

I have a file located in /etc/NetworkManager/conf.d with the configuration of:

Code:
[connection]
wifi.powersave = 3

# 'permanent' uses the hardware mac address, 'preserve' keeps the mac address the same, 'stable' generates a permanent mac address per network, 'random' generates mac per each connection/association
# I presume to assign a specific address you add it at the end of the '=' sign or have an empty space between; e.g., ethernet.cloned-mac-address=00:22:68:1c:59:b1
# OR ethernet.cloned-mac-address 00:22:68:1c:59:b1

# Ethernet setting
ethernet.cloned-mac-address=random
# Generate a random MAC for each WiFi and associate the two permanently.
wifi.cloned-mac-address=random

I attempted to restart NetworkManager in various ways,
Code:
systemctl restart NetworkManager
sudo killall -SIGHUP NetworkManager
sudo nmcli con reload
I have just did this before I did anything of this, today:
Code:
dpkg-reconfigure resolvconf
This is to fix the inability to log-in to a network that prompts for an "Agreement" via webpage.

I have Private Internet Access installed.


After I do all of this and connecting to a network that I have to accept and agreement on a webpage, no changes are found via ifconfig and ip link. The default MAC address still exists. Each time the network reconnects without prompting for an "Agreement page" telling me that I'm using the same MAC address as before.

I previously had a separate configuration file in the conf.d directory. I tried putting the configuration into the NetworkManager.conf file.


My version is 16.04 Ubuntu-MATE

NetworkManager version 1.2.6

I am having some dips in bandwith that cannot be explained by any activity I know about.

I have looked at Nagios but it is more than I need. I don't need an elaborate UI and I don't want to have to install and configure apache.

Hoping for a simple commandline tool.

Anything?

How to remote access from Outside the LAN

September 20, 2019, 6:56 pm

Hi everyone,

Ive been experimenting with remote access. Aside from the obvious team viewer and anydesk, there are other alternatives such as nomachine, VNC viewer, etc...

Doing this over LAN is easy. Just put the IP address of the computer we want to control in the viewer PC and viola! It works. However, when we want to access the computer from outside the LAN, I am confused.

The instructions on sites such as Nomachine says just put in the IP of the machine... some of the VNC viewers say the same thing too. However, my computer's IP is merely the result of what my DHCP server tells it. It is a local IP address and many other computers around the world might have the same local IP.

So I used google to look up "what is my IP", and I get some sort of global IP... However, the computer beside mine also has the same global IP result when I look it up there. And this IP also doesnt work.

So what value should I put so that remote access can work for a computer through the internet? Thank you.

1 Computer 2 Networks 1 IP address

Hi everyone,

I have a computer with 2 LAN ports.

SERVER 1 has 2 LAN ports:
LAN port 1 will connect to LAN "A"
LAN port 2 will connect to LAN "B"

The Computers connected to LAN "A" are different from the computers connected to LAN "B"...

My question:

Can I setup the 2 LAN ports so that they will have the same IP address? In this way if I transfer a computer from LAN "A" to LAN "B", I don't need to change their settings, they will continue looking for the same server address and it should work.

I think this will work but my IT says it will create a conflict so he doesn't want to go with it. However, thanks to your help in previous posts, I was able to disprove him on a few topics regarding our network.

Thanks so much.
