Resolved Error systemctl restart network

Branko

Basic Pleskian
Hello,

When I try to systemctl restart network the following error pops up
Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.

After systemctl status network.service there is

It all happened after trrying to setup IPv6 on my VPS server.

Also tried stoping and starting NetworkManager but there is error
Failed to start NetworkManager.service: Unit not found.

Every response is highly appreciated, thank you ina advance.

Must note that my server is up and running, and network is avaliable. As I can tell everything is functioning good.
 
Hi Branko,

to investigate issues/errors/problems, it is always wise to add:
  • YOUR current used operating system
  • YOUR current used Plesk version ( incl. # MU )

The more information you add, the better might be ( possible ) solutions and work-arounds, to solve your issue.

Unfortunately, you shortened your error - messages, so that we are not able to see the full messages. :(

Can you help something with this, please?
 
Hi Branko,

warning: master_wakeup_timer_event: service pickup(public/pickup): Connection refused
Points to a misconfiguration at your "/etc/postfix/master.cf"

The standard configuration of postfix is based on the unix interface usage, but newer operating system will use fifo for "pickup" and "qmgr". Plesk should have added:
Code:
pickup fifo n - - 60 1 pickup
qmgr fifo n - n 1 1 qmgr
... and you should make sure, that
Code:
pickup unix n - - 60 1 pickup
qmgr unix n - n 300 1 qmgr
... has been commented with a "#" in front of the standart configuration lines.​


For your network issue, it could be a good idea to REREAD the IP(s) over your Plesk Control Panel ( => "Home > Tools & Settings > IP Addresses" - Button "Reread IP" ), or by using the command ( logged in as user "root" over SSH ) over the command line => /usr/local/psa/bin/ipmanage --reread
 
Thank you for fast response, you are really great.

Did already the fix for unix to fifa, checked now again, but it is properly done.
Also, I have done REREAD before, tried it again, but it didn't help.

Restarted server also, but it is the same error.

Could it be some IP clash? It started happening after adding IPv6 addresses to the server.
Is there some safe command for IP flushing that would you recommend?

Thank you very much again, everything you say is helpful.
 
When done # postfix check

postfix/postfix-script: warning: not set-gid or not owner+group+world executable: /usr/sbin/postdrop
postfix/postfix-script: warning: /usr/lib/sendmail and /usr/sbin/sendmail differ

lrwxrwxrwx 1 root root 30 Aug 18 17:20 /usr/lib/sendmail -> /etc/alternatives/mta-sendmail


How to "Replace one by a symbolic link to the other"?
 
Hi Branko,

Is there some safe command for IP flushing
There is no such "feature" or command as your network - configuration is not equivalent to "iptables" for example. ;) But you are still able to remove your whole configuration ( first over the Plesk Control Panel and pls. check afterwards, that there is no leftover at your network - scripts - folder ( => /etc/sysconfig/network-scripts ) on your server ).

Pls check afterwards, that your basic configuration works without issues and only if this is the case, you would try another new IPv6 configuration attempt.

Pls. don't modify any sendmail related links/symlinks/configuration. There are in most cases fine and working as expected and have got nothing to do with your network settings. :). But correct the
not set-gid or not owner+group+world executable: /usr/sbin/postdrop
... issue, with ( logged in user "root" over SSH ):
Code:
postfix set-permissions


If you experience issues with postfix and sendmail, it is most likely the case, that you tried to install the "sendmail" - package with your software package manager ( "yum" / or "apt-get"/"aptitude", depending to your operating system ). Pls. note, that Plesk has it's very own package here ( which comes with the corresponding "plesk-mail-XXX-driver" and any additional packages might conflict here. Pls. remove any additional "sendmail" - packages and correct possible related issues with the example commands:
Code:
plesk installer --select-product-id plesk --select-release-current --install-component qmail
plesk installer --select-product-id plesk --select-release-current --install-component postfix
or/and use the Plesk Repair Utility to correct possible misconfigurations:
Code:
plesk repair mail -y -v
 
For your network issue, it could be a good idea to REREAD the IP(s) over your Plesk Control Panel ( => "Home > Tools & Settings > IP Addresses" - Button "Reread IP" ), or by using the command ( logged in as user "root" over SSH ) over the command line => /usr/local/psa/bin/ipmanage --reread

Even after REREAD from Plesk control panel and server restart the problem remains.
Are there any other options?

I fixed Postfix issues.

Hello, I removed all IPv6 addresses. Server is working great, everything is up.

But network still cannot be restarted.

Can you suggest solution?
 
I am hosting on LeaseWeb. I saw in their docs that they forbid DHCP.

Is it ok to set up BOOTPROTO=static ?

What consequences will it make? Is DHCP default Plesk option? Or is it just in my server settings?

Just for a reminder my system is:
Version: Plesk Onyx v17.5.3_build1705170317.16 os_CentOS 7
OS: CentOS Linux 7.4.1708 (Core)

Ok, I changed BOOTPROTO=none in /etc/sysconfig/network-scripts/ifcfg-eth0
Network restarted without an issue.

My /etc/sysconfig/network-scripts/ifcfg-eth0 now looks like this

DEVICE="eth0"
ONBOOT="yes"
NETBOOT=yes
IPV6INIT=yes
IPV6_DEFAULTGW=fe80::1
IPV6_DEFAULTDEV=eth0

Do you see here something problematic? Is there something missing that I should add? Or something to remove or change?
