 Posted: Thu Jul 26, 2018 2:09 pm Post subject: Iptables virtual service warning... |
 |
|
OK, I googled for this but did not find anything helpful, so I am going to ask here. For over a year I have been getting the following upon boot and upon restarting certain services.
| Code: |
Error: iptables is the name of a real and virtual service.
Error: ip6tables is the name of a real and virtual service.
Error: ebtables is the name of a real and virtual service.
|
What is this, how do I fix it, or how do I silence it? I believe my firewall is working just fine.

Run this:
| Code: | | egrep -r '\bprovide ' /etc/init.d/ |
If you see any files that mention iptables in the list, check that they're owned by some package. Things in /etc/init.d/ sometimes don't get uninstalled automatically but openrc still picks up on them. |

I ran the script you posted and got the results as follows.
| Code: |
~ $ sudo egrep -r '\bprovide ' /etc/init.d/
Password:
/etc/init.d/net.lo: provide net
/etc/init.d/net.lo: for dep in need use before after provide keyword; do
/etc/init.d/opentmpfiles-setup: provide tmpfiles-setup tmpfiles.setup
/etc/init.d/swclock: provide clock
/etc/init.d/devfs: provide dev-mount
/etc/init.d/udev-trigger: provide dev
/etc/init.d/osclock: provide clock
/etc/init.d/hwclock: provide clock
/etc/init.d/net-online: provide network-online
/etc/init.d/udev-settle: provide dev-settle
/etc/init.d/opentmpfiles-dev: provide tmpfiles-dev tmpfiles.dev
/etc/init.d/sysklogd: provide logger
/etc/init.d/lircd: provide lirc
/etc/init.d/busybox-syslogd: provide logger
/etc/init.d/ipsec: provide ipsec
/etc/init.d/cronie: provide cron
/etc/init.d/NetworkManager: provide net
/etc/init.d/dmcrypt: # This is ugly as s**t. But POSIX doesn't provide `read -t`, so
/etc/init.d/firewalld: provide iptables ip6tables ebtables
|
Everything there is owned by something on the system. For example, I use firewalld for firewall zones in NetworkManager in Plasma. Obviously net.lo is needed, NetworkManager is used, as is cronie, sysklogd, etc. The only thing I am not sure of is "net-online". I did not explicitly install it, but it is there.
| Code: |
~ $ sudo equery depends net-online
* These packages depend on net-online:
|
Nothing appears to need it. Should I remove it?
*EDIT*
It doesn't seem to be a package at all.
| Code: |
~ $ sudo emerge --search net-online
[ Results for search key : net-online ]
Searching...
[ Applications found : 0 ]

| As you discovered, /etc/init.d/net-online is owned by a package with a name other than net-online, so you cannot use equery depends net-online to check whether it is needed. Instead, use equery belongs /etc/init.d/net-online to find the owning package, then use equery depends or emerge --pretend --verbose --depclean on that package. |

The_Great_Sephiroth ... net-online is owned by sys-apps/openrc, and "delays until the network is online or a specific timeout".

Thanks for the information. As soon as firewalld fixes the issue I will mark this as solved.
