[ubuntu] SFTP access without limitations

June 18, 2020, 10:49 am

Hi guys,

I am tasked with configuring a server for SFTP and rsync access, sounds easy enough... Right?...

The rsync runs over SSH, just like SFTP does. I configured the Ubuntu server (in fully offline environment) for SSH access and rsync and then proceeded by adding the following config that you can retrieve in 99% of the SFTP Ubuntu tutorials:
Code:
Match group sftp
ChrootDirectory /home
X11Forwarding no
AllowTcpForwarding no
ForceCommand internal-sftp
This basically does what it says it does and pay attention to the fact that we are limiting the SSH access to the /home directory and limiting the only SSH based access to SFTP. This works like a charm for SFTP access to the specific directory. It does however limit all SSH access to the specified directory only and to make matters worse it limits all SSH access to the use of SFTP commands only.

Obviously rsync will not be allowed using this configuration and even without the ForceCommand you can still not properly use rsync as it requires access to different directories that are not present in any user's home folder.

So, that's not an issue, let's remove the ForceCommand and ChrootDirectory and continue. Oh wait, SFTP doesn't work anymore?? Okay let's look up other tutorials/guides that explain how to configure Ubtunu for SFTP access, and pick out one that doesn't use the ForceCommand or ChrootDirectory config changes. Oh wait, there are none such guides??

Okay guys, either I am stupid and missing something here? Or There is really no way to configure SFTP and any other type of SSH based access to the same server? Let's hope this is me being stupid.

Any help on this would be very appreciated!


Cheers :popcorn:

[ubuntu] USB Wi-Fi adapter no longer connecting to internet, Realtek 8812au and Panda PAU09

Hi, I'm running Ubuntu 18.04 LTS on my PC and recently my BrosTrend Wifi adapter which uses Realtek 8812au stopped connecting to Wifi, even though it can still detect the nearby networks. I also have windows dual booted on my PC and the Wifi connects perfectly fine there, so it leads me to believe that this is a compatability issue with the Wifi Adapter on Ubuntu, or maybe the driver is no longer compatible with the Linux kernel (even though I have software updates disabled). For the past few months I had been using this driver I found on Github here https://github.com/gnab/rtl8812au and it has worked perfectly fine. I followed the instructions, ran make and insmod and copied the 8812au.ko file into
Code:
/lib/modules/5.3.0-51-generic/kernel/drivers/net/wireless
(I didn't need do any of the dkms stuff, and I don't have the command downloaded, so please don't ask me to do any dkms commands)

But now, it doesn't connect at all to any network. To troubleshoot, I tried deleting the 8812au.ko file, re-running make, and re-running insmod and re-copying it to that folder, rebooting, etc. Nothing worked, so I purchased the Panda Wireless USB Adapter PAU09 since it was advertised as plug n play and supports Ubuntu 18.04, and I didn't want to go through any obscure tutorials anymore or rely on a driver on the internet that isn't regularly maintained which will probably stop working in the future anyway. To my surprise, it also didn't work! It also has the same issue as the other wifi adapter--the wifi settings say "Connecting" after selecting a network only to never connect. What is my issue here? And FYI my PC does not have an internal Wifi card.

sshd keys - still prompting for root passwd

June 20, 2020, 9:48 am

I'm attempting to set up ras keys for ssh to allow remote rsync backups of all users home directory.

I've set up the keys for a normal user and that works as expected
I've generated keys for the root user and copied them to the server.

I edited /etc/ssh/sshd-config to change

Code:
#PasswordAuthentication yes
to
PasswordAuthentication no
and
Code:
PermitRootLogin no
to
PermitRootLogin yes
But I'm still getting a prompt for a root login, which works.
But I don't want to do that with the crontab

I've obviously missed something.

I generated the root keys in a sudo shell I wonder if that makes a difference in the keys generated.

The goal is to allow root to make the backups via a crontab from a designated machine(s) and not be able to login as root using a password.
I ideally a regular user would be able to login using a password in case I need access and haven't been able to provide a key for the machine I'm logging in from.

Intel 3160 wifi not working

The wifi on my intel i3 (3160) suddenly stopped working in 18.04 So I upgraded to 20.04 and it doesn’t work there either.
Were there changes in 18.04 that could have caused this? The command lshw -C network shows the adapter is there.
ANd I loaded the u.code suggested by intel (14). What else do I need to do? Thanks for your help.

Quick general question,
There is a lot of bug reports for isc-dhcp-server for focal (including one where it crashes on launch if in a cluster), but not much activity. Does any one know is this package is still maintained (or how i can find out).
Many Thanks

wpa_supplicant CTRL-EVENT-DISCONNECTED reason=0 and slow with a BCM4360 wireless card

I'm running Ubuntu 19.10 x64 and using the default bcmwl-kernel-source version 6.30.223.271+bdcom-0ubuntu5

I get repeated wifi disconnections and speeds around 90kBps from my Broadcom BCM4360 wireless card.

Can you suggest how to fix this? TIA.

Internet no longer working after upgrading from Ubuntu 18.04 to 20.04

June 21, 2020, 10:56 am

Let's cut to the chase... TL;DR I'm a long time Windows user and am new to Linux. I do not really think highly of Linux because of its complexities and hard to use/repair situations such as these ones. I upgraded from Ubuntu 18.04 to 20.04 using `do-release-upgrade`, and it went quite smoothly, preserving my GRUB boot menu and software settings, but the upgrade has rendered my system completely unable to use the Internet. How bad is it? The network activity lights next to my LAN port don't light up at all, as if the network wire was disconnected... I actually initially thought the network adapter on my laptop got fried or something, but it works perfectly fine on other OS's (I am currently triplebooting 3 OS's, Internet works fine on the other two)


Here is the inxi output for some hardware info: Keep in mind this was done back when I still had Linux Mint(which I don't have anymore),so some information, especially software-related, maybe wrong but hardware info should be pretty much the same.

So my suspicions are that the Ubuntu upgrade somehow removed some of the drivers for the hardware in the system, and the Ethernet controller was one of them. Without it, the system is unable to dial a PPPOE connection, and hence I can't use the internet.

I ask the Ubuntu experts for help on this matter...
Thanks in Advance!

[ubuntu] Two Ethernet Ports - Swap/Disappear

June 22, 2020, 5:48 am

Hi All

I'm running Ubuntu 20.04 LTS on a old server board S1200BTL as a home server. The motherboard has two ethernet ports. I connect to my LAN via a B525 Huawei wireless router. The home server is hard wired to the wireless router via the ethernet port.

My problem is that after a restart or startup the ethernet port sometimes disappears so that to get it to re-appear I must then unplug the ethernet cable from the one port on the server and plug it into the other. Then the network re-appears. This manual swapping of the ports is a real pain as the PC is not super accessible.

Any ideas as to why it swaps or how if it does keep swapping I can get both to be automatically enabled?

Forgot to say I have eth0 and eno1 showing and ethernet controllers are Intel 82579LM and 82574L.

Thanks in advance.

Hello.
I hope someone can help me here...
As the topic says. a message before "login as:"

I have edited sshd_config with Banner /etc/issue.net and as I understand it it works like this


(I would like my massage here)
Login as:
(issue.net is shown)
Password:
(motd is shown)

I have done this many years ago but i don't remember how? I have an idea it had something to do with a file that was overwritten everytime the machine was rebooted, and another idea i have is that it was a file to edit that begun with a dot (.) that you had to edit.

If someone could help me with this my head will have much more hair on it in the future.

Regards Christian.

hi

im trying configuring vlan interface that assign to vrf on a 20.04 ubuntu desktop machine.
ive used iproute2 for that.
ip link add link ens160 name ens160.105 type vlan id 105
ip link add 105 type vrf table 5
ip link set dev 105 up
ip rule add iif 105 table 5
ip rule add oif 105 table 5
ip link set ens160.105 master 105
ip link set ens160.105 up
ip addr add 10.1.5.3/24 dev ens160.105
ip route add 0.0.0.0/0 via 10.1.5.1 table 5
at this point the vlan int works and i can ping through the vrf.
but when im resetting the machine all config disappear.
another issue is that i cant configure dhcp and i cant configure dns (name servers) for that vrf.

ive tried using netplan but it didn't work.

any ideas?
ill appreciate any help

thanks all

[SOLVED] Installing Lubuntu on HP Stream Notebook 13 using Broadcom Network Adapter - NO Inter

I was installing Lubuntu 20.04 LTS onto an HP Stream Notebook 13 and I couldn't get the Broadcom Network Adapter to function.

I found under Preferences -> Additional Drivers that it saw the drivers I needed and it wanted to download them. Unfortunately it was giving the error that it couldn't proceed without an internet connection. This Notebook does not have an ethernet port so I tried a USB Wifi Adapter but had trouble getting the correct drivers to get it to work as well. I tried to download drivers from my other laptop onto a USB Flash Drive and install them manually but they kept failing with "needing additional dependencies" and those dependencies needed more dependencies. So it seemed as it would be a never ending trail. I'm guessing there is a better way but I am not well versed on how to do that.

I also saw online some people were able to connect by tethering their cell phones. So I finally tried plugging my Iphone into the Notebook and turning on my hot spot and Voila! It connected immediately letting me download the Broadcom Drivers. Then I proceeded to install Lubuntu.

Please feel free to add anything that could help with people that the cell phone tethering doesn't work for.

Thank you,

Apache2 no permission to save files in /var/www/html

As topic says. I have installed apache2 and it works and I see the index.html that says ”It works!” That file is located in /var/www/html. But I don’t have permission change any file in that folder? Why is it like this?
