[SOLVED] systemd + lost networking

After the last update I seem to have lost my network. Systemd complains it cannot find the network.service file.
The systemd package only contains network.target and not network.service
How can i manually start the network ( simple eth0 + dhcp).
And how can i fix my system?

[Solved] systemd - network-online.target inactive dead

Still trying to get familiar with systemd after years with Ubuntu.
I have Crashplan installed and it's systemd service unit has the following line to wait until the network comes online.
After=network-online.target
However, this doesn't seem to be working. While trying to investigate this, I noticed that the target shows as 'inactive' and 'dead'. Not entirely sure what that means.
➜ ~ systemctl list-units --type=target --all | grep network-online
network-online.target loaded inactive dead Network is Online
Where can I go from here to make sure my Crashplan service only starts after the network is online?
Thanks.

Do you actually have a working connection?
Well, I'm connected to the internet via Wifi by the time I get past my lightdm greeter. Not sure if systemd wants something else.

[SOLVED] systemd-udevd renames network interfaces

During install I enabled dhcpcd service like this:
systemctl enable [email protected]
Seems perfectly valid, eh? But after reboot network I've got the following messages:
[ TIME ] Timed out waiting for device sys-subsystem-net-devices-eth0.device.
[DEPEND] Dependency failed for dhcpcd on eth0.
dmesg | less
systemd-udevd[111]: renamed network interface eth0 to enp0s3
It appears systemd changes network interface names. But then I suppose [email protected] is to be removed:
[Unit]
Description=dhcpcd on %I

Before=network.target
BindsTo=sys-subsystem-net-devices-%i.device

old to Linux new to archLinux
jasonwryan -thanks!
Your post helped me figure it out why my Ethernet interface name was changed to enp0s3 and why - I like the old naming convention ethx easier for me to remember. So went the route with custom rules in /etc/udev/rules.d
Here is what I used.
70-my-net-names.rules
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="08:00:27:3b:f3:cd", NAME="eth0"

App says "Lost network connection, restart app"

my banking app comes up with "Lost network connection. Please tap home below and restart app"
I've tapped home twice, slide up the app and tried again - no luck.
Please help.

This issue can most likely be solved by contacting the developer of the app. That information in is the information about the app in the App Store.

How to solve this problem?

Hi, I discovered in (Win 7 & 8 I assume) that if you go into your network adapter settings and click 'Configure' then go to the 'Power Management' menu there is an option to 'Allow the computer to turn off this device to save power'. I unchecked this and now no more crashing with the network connection lost error. Not sure it will work for everyone but might be the solution for some.

Lost Network Link

Maybe a power failure and than a reboot?!
Or after an updat of the system software and if you've edit the hostconfig file and changed the HOSTNAME=-AUTOMATIC_ to HOSTNAME=FQDN? Than the automatic lookup doesn't work as it should.

[SOLVED] systemd+wpa_supplicant, but the name of interfaces changes

Hello,
I'm following instructions here for having the wireless connection ready at boot on my machine.
I needed to setup two different daemons since sometimes my wireless interfaces is wlp3s0 and sometimes is wlan0.
When the name of the interface is wlp3s0 everything works fine and I'm correctly given an IP address.
It doesn't happen the same when the name is wlan0.
Here's some output

Check your journal for messages relating to wlan0 and wlp3s0. I think you may find some kind of error message -- maybe having to do with firmware. I've seen thing like that break predicatible device names
If you've just one wlan interface, you could turn off predicable device names and just go with wlan0

Systemd-nspawn Network

This post talks about systemd-networkd NAT for systemd-nspawn but doesn't explain on how to set it up. I current have virbr0 created by Libvirtd which I can get a NAT address inside the container with LXC and systemd-nspawn --network-bridge=virbr0 --port 80:80 -jbM ubuntu-nginx but port 80 is not forwarded on the host unlike if I ran docker run -d -p 80:80 nginx. How can I create a virbr0 like NAT interface using systemd-networkd instead of Libvirtd and get systemd-nspawn port forwarding to work?

-p, --port=
If private networking is enabled, maps an IP port on the host onto
an IP port on the container. Takes a protocol specifier (either
"tcp" or "udp"), separated by a colon from a host port number in
the range 1 to 65535, separated by a colon from a container port
number in the range from 1 to 65535. The protocol specifier and its
separating colon may be omitted, in which case "tcp" is assumed.
The container port number and its colon may be ommitted, in which
case the same port as the host port is implied. This option is only
supported if private networking is used, such as --network-veth or
--network-bridge=.
which seems to say valid options are tcp:80:80, 80:80 and 80. I am under the impression --port automatically setups up the necessary routing like Docker but that doesn't seem to be the case. If private networking is enabled with
systemd-nspawn --private-network --port 80:80 -jbM ubuntu-nginx
then only localhost would be available inside but the port should still be forwarded to the host?

[SOLVED] systemd dhcpcd on boot failure

For the past month or so, my systemd service for dhcpcd has been failing to properly start on boot. However, I've noticed that this only occurs on a fresh start after a shutdown. It does not occur after a reboot.
I do not use any sort of connection manager such as: NetworkManager, netctl, connman, etc.. I am only using dhcpcd via systemd.
The command I've always used to create the service is:
# systemctl enable [email protected]
# systemctl start [email protected]
I've found some topics related to the issue from 2-3 years back, but they don't seem to be the exact same case from what I can tell.
Here is the output of systemctl --type=service --all: http://i.imgur.com/hqBZBoP.png
Here is the output of ip link show when the service is running:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
link/ether **:**:**:**:**:** brd ff:ff:ff:ff:ff:ff
Does anything seem off in my service list? This issue is really nagging at me, and I don't know enough about systemd or networking to isolate it.

Removed ip access-list & lost network connectivity

An access-list was removed to edit and replace. Once the access-list was removed we lost network connectivity to the remote router. This list is an extensive one. But when we remove on other remote routers network connectivity remained. Can anyone tell me why? Is this a typical of access-list, and good practice is to wait until after business hours?

No problem.
I am sure that we have all had experiences of looking at things we have written, or questions answered, and realized that what we wrote was not quite what we were thinking as we created it.
Your main point is well taken that it is good practice to remove the access-group before removing and changing the content of access lists.
Sometimes I take a slightly different approach: I will build a new version of the access list using a different number (if I am changing access list 101, I may create list 102) which is the modified version of the list. I then change the access-group to reference the new version of the list. This may have a couple of advantages including the fact that the interface is always protected by some access list. Also it makes backing out changes easier if we discover that there was some flaw in our list modification.

How do you fix Backup Assistant Plus Lost Network

I have a Samsung S4 Mini. It came with Verizon's Backup Assistant Plus installed. I believe it should backup my contacts to a Verizon server somewhere. However, since the day I got the phones, Backup Assistant Plus fails every night with a "Lost Network Connection. Please Try Again". It doesn't matter if it connected by WiFi or Verizon 4g data. The error will happen if the Sync Contacts is checked or un-checked. The only options for this app are a check box for Sync Contacts and the Sync Time. There isn't any option to Remove Account, Disable, or Un-install. I've tried Clear Data and Clear Cache. There is some vague information on Verizon saying the Verizon Cloud replaces Backup Assistant Plus. I enabled Verizon Cloud and it seems to backup my contacts ok. But Backup Assistant Plus continues to attempt and fail.
- I do not want Verizon backing up anything, How do I disable, or remove Backup Assistant Plus?
- If I can't remove Backup Assistant Plus, How do I stop the constant Backup Assistant Plus failures?
- If Verizon Cloud replaces Backup Assistant Plus, why is it still installed and running?
- And the obvious question - - Why does Verizon insist on backing up my contacts whether I want to or not?

I just had a similar problem and tried many of the steps on these Blogs. None of them worked. But I did get it working by turning on my Data. I normally keep Data off and use WiFi as much as possible so the Sync was failing and I was getting the Lost Network notice. But as soon as I turned on Data it started uploading and downloading my contacts. That was all BAP. But I could go to the Cloud and update via WiFi just fine.
So, why did I still work to get BAP working? BAP was stuck in a loop to try and get the Backup done. Since it couldn't it tried repeatedly and I believe it is why my battery was draining more rapidly than normal. Hopefully by turning on DATA the battery may last longer. If not I need to turn BAP to manual backups only. I hope I can find out how to do that.

Lost network connectivity to LOM

Hi,
We lost network connectivity to the LOM interface card. Does someone know if there is any way to restart the LOM remotely? I have access to the server by ssh. Server is a SunFire X4200

Hi.
Not sure that is possible.
Try read docs about ipmitool
