[ubuntu] Resuming from hibernation deactivates wifi

Hi,
I recently activated the hibernation feature (in Ubuntu 14.04) and while it works well, I realized that upon resuming the session, cannot access internet
through the wifi connection. It appears that no networks are available and that actually the wireless mechanisms appears deactivated, so there is apparently no way that I can reopen the connection to internet.
Has anyone experienced this? Any ideas on how to fix this?
Best regards

Hello, i've installed 16.04lts gnome on two machines from the same source. On one of my machines the network manager does not display a wired option and ethernet is not recognized when plugged in. I've attached a screen shot of the network manager. I'd greatly appreciate any advice on resolving this issue. Thanks!

[ubuntu] Network card does not working : systemctrl status networking.service

I am new to Ubuntu. In my office, There is a system with Ubuntu 16.04 64 bit connected with DNS server with enp2s0 card. Now it was suddenly disabled. I tried to restart network after give # (hash) to all lines in /etc/network/interfaces.
It is:
Code:
auto lo 
iface auto inet loopback 

auto enp2s0 
iface enp2s0 inet static 
address 192.168.0.50 
netmask 255.255.255.0 
gateway 192.168.0.1 
dns-nameservers 192.168.0.100 
dns-search xxx.com
except first two lines, which I entered after normal installation. Then restart the network using /etc/init.d/networking stop, then /etc/init.d/networking start/restart Then the system shows:
Code:
starting networking (via systemctrl): networking.serviceJob for networking.Service failed because the control process exited with error code.
See "systemctrl status networking.service" and "journalctrl - xe" for details**.
I don't know how to check. I think somebody played with. in ifconfig, only lo shows.
network card is OK. (I tried system with another HDD with same OS installed).

I'm on Ubuntu 16.04 and the ethernet port is not working. Something is recognized as being there, but it does nothing, doesn't even light up when I plug in an internet connection. I have a usb ethernet dongle that i have been using that works fine though.

I know the lan is realtek, but I can't find info about specifically what kind besides 10/100/1000.

Does anyone know how to get thees working?

My wired connection sometimes stops working, then it comes back by itself. If I use a USB ethernet adapter when it's down I can get a connection; if I boot the live USB I can get a connection, but for some reason my 2 PCI network adapters stop working sometimes.

[ubuntu] Two interfaces, both auto, second won't come up on reboot

October 16, 2017, 6:20 pm

Running Ubuntu 16.04 server and having an issue with my network interfaces. The system pretty much works great but when I reboot the second interface won't automatically come up. For context I have a WAN interface (enp1s0, DHCP, works perfectly) and a LAN interface (enp2s0, static, not so perfect). The LAN interface shows down after a reboot and stays that way until i run "sudu ifup enp2s0". After that all is well...

Here's the contents of /etc/network/interface -

Code:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).


source /etc/network/interfaces.d/*


# The loopback network interface
auto lo
iface lo inet loopback


# The primary network interface
# WAN interface port labeled 1
auto enp1s0
iface enp1s0 inet dhcp


# LAN interface port labeled 4
auto enp2s0
iface enp2s0 inet static
    address 10.0.0.1
    netmask 255.255.255.0
#    broadcast 10.0.0.255
#    network 10.0.0.0


# Port labeled 3
#auto enp4s0
#iface enp4s0 inet dhcp


# Port labeled 2
#auto enp3s0
#iface enp3s0 inet dhcp
Any ideas on what to look for? I added the broadcast and network statements based on another post. Didn't make a difference in the issue so I commented them out.

Network is delayed at startup

Hi

I had an ubuntu server running Plex Media Server for some time and it worked just fine. When I recently tried to update the server to a new version, it somehow crashed and I had to do a clean re-install. That went fairly smooth and it is up and running again.

Although now I have a small problem that comes up after each reboot. Plex server apparently can't log in as the network service is not yet fully up and running. So I always have to do that manually. Below are some of the errors from the Plex log file.

Code:

This shows the LAN interface was not visible

It was only at this point that the LAN interface became visible

Code:

Then at this time - it started to work

Code:

Is there a way to ensure that the network is up and running as it should before it proceeds with booting up?

Or as an alternative, can I somehow delay the startup of Plex to wait till the network is fully up?

I have the following installed:

Code:
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.3 LTS
Release:        16.04
Codename:    xenial

The machine is connected with a cable to the router which provides a static IP address (192.168.0.6).

As I am very inexperienced with Linux, please provide very detailed descriptions as to what I can do to get this working.

Thank you very much in advance.

[ubuntu] Multiple Static IPs on one NIC Ubuntu Server 16.04

Hi
I have been trawling the internet for ages. So far I have not found any info that will allow me to assign multiple Ips to one network card.

My current config runs Public IPs and is set as shown

Quote:
auto lo enp17s0
iface lo inet loopback

iface enp17s0 inet static
address 109.xxx.xxx.xxx/27
gateway 109.xxx.xxx.xxx
broadcast 109.xxx.xxx.xxx
network 109.xxx.xxx.xxx
dns-nameservers 8.8.8.8 109.xxx.xxx.xxx 109.xxx.xxx.xxx
I need to add 4 more IP address's in the same /27 range

Does anyone know how this can be acheived correctly. It was a lot easier in Server 14.04 :)

iptables ping and ssh

I have looked at several online articles on iptables rules and I am getting some conflicting opinions.

Is "-A INPUT -i eth0 -p icmp -j ACCEPT" correct to allow ping's on eth0?

Is "-A INPUT -i eth0 -p tcp -m tcp --dport 22 -j ACCEPT" correct to allow ssh connections?

Below is the full iptable

I'm having issues with making ssh connections. Right after the server is rebooted I get public key errors connecting to that server. If I move a keyboard+monitor and login in directly then remote ssh sessions connect successfully. It only takes one time directly, logout immediately afterwards, and then everything works fine...until the next reboot.

Any ideas?

Configure sftp directory

Hey guys

I'm trying to access a specific (and only this) location on my server. It's running openssh-server and root works fine.

What I already did:
- created a group foo-group
- added user foo to this group
- accessed file system via sftp

What I want to achieve:
- Login to folder /mnt/foo
- Have permission to write on /mnt/foo

I tried to add this to the /etc/ssh/sshd_config
Code:
Subsystem sftp internal-sftp
Match group foo-group
            ChrootDirectory /mnt/foo
            ForceCommand internal-sftp -d /default
When I try to restart ssh, it throws me
Code:
Job for ssh.service failed because the control process exited with error code. See "systemctl status ssh.service" and "journalctl -xe" for details.
Which doesn't help me tho...

Any idea what went wrong?

Thx for help!

PS:
/mnt/foo is obviously not the real directory, but holds for a subdir on a mounted harddisk

[ubuntu] Some pages not beeing loaded in chrome

Hi. I've started to have some issues with google chrome like a week ago. This is in the computer at my office, and some changes I think that have been done in the internal network, I don't know if this is related to this. However, it is weird, because some pages work normally in chrome, and I can open any page without any trouble in firefox. But there are lot of pages that I can't access with chrome.

I have tried to remove and reinstall chrome, and I've also installed chromium, but the problem persists. The configuration for the proxy in firefox and chrome seems to be the same (the one for the system).

Any ideas?

Hi Guys
I have the following config with multiple IPs. However with multiple IPs my DNS is not working correctly. I can ping IP address's but I cannot resolve domain names with ping unless i only have a single IP assigned. Has anyone found a way around this please?

I have tried it with both dns-nameserves added in the interfaces file and with them remmed out.
Code:
                auto lo enp17s0
                iface lo inet loopback

            iface enp17s0 inet static
                address 109.xxx.xxx.xxx/27
                gateway 109.xxx.xxx.xxx
                broadcast 109.xxx.xxx.xxx
                network 109.xxx.xxx.xxx
                #dns-nameservers 8.8.8.8 109.xxx.xxx.xxx 109.xxx.xxx.xxx

        iface enp17s0 inet static
                address 109.xxx.xxx.xxx/27

        iface enp17s0 inet static
                address 109.xxx.xxx.xxx/27

        iface enp17s0 inet static
                address 109.xxx.xxx.xxx/27

Hi,
After DSL-Router Firmware Update (and factory reset) I got this problem with wifi.
To get connection again I have to click each time in the List of available wifi's on my Router.
It happens on Ubuntu notebook only, other wifi devices do not loose connection
The Router is FritzBox 7330

uname -a:
Code:
Linux lenovo-g70-70 4.4.0-97-generic #120-Ubuntu SMP Tue Sep 19 17:28:18 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
Does it have something to do with this:
egrep -i 'net|eth|wlan|firm|reason' /var/log/syslog :
