Hi everybody !

I'm using gentoo with I3 wm in a relatively new laptop , I well remember that when I use my previous laptop I had insert a line for exec on startup a networking tool
that automatically connect the system to the ethernet dhcpcd or to a known wireless that I had already used remembering its password ..

Now I don't want know which was this tools .. but I would like to know how can I obtain this behavior ...
Thanks in advance

Hi,

Nowadays, dhcpcd + wpa_supplicant can do that trick. You just have to start both services and dhcpcd will manage your networks.

I've used wpa_supplicant+dhcpcd for years but lately I caved in and finally decided to install net-misc/networkmanager. Its fingerprint is nothing compared to the usual beasts that I need to recompile everyone and then and having a curses interface (nmtui) is useful when in places that I need to search for a network (instead of running wpa-cli look for search results and hope that the screen doesn't scroll fast, go and edit the .conf file and so forth)

EDIT: It seems NM adds a service:
Code:
$ equery files networkmanager  | grep init
/etc/init.d
/etc/init.d/NetworkManager

the systemd service reads as follows:
Code:
 $ cat /lib/systemd/system/NetworkManager.service | grep Exec
ExecReload=/usr/bin/dbus-send --print-reply --system --type=method_call --dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.Reload uint32:0
#ExecReload=/bin/kill -HUP $MAINPID
ExecStart=/usr/sbin/NetworkManager --no-daemon


So I suppose adding a hook to those should work.

I suppose reading the Gentoo Wiki would help. No?

Agreed. I like nmcli and nmtui, particularly nmtui. The latter has made life easier when a DE won't start for whatever reason and I need to connect to a network in order to install/re-install some package or other to fix something. Had to use it again just last week.
