 Posted: Sat Sep 28, 2024 7:30 am Post subject: [partially SOLVED] Samba won't bind to network at boot |
 |
|
I recently setup a new Gentoo installation. On this I wanted samba to be available after boot to share data with a windows PC.
Thus on the Gentoo machine, samba is installed and added to the default runlevel. But it does not bind to the network (enp3s0) at boot. The network is using dhcpcd.
For debugging I enabled samba log level 3.
At first I tried using "net-online" in addition in the default runlevel and let samba need it: rc_need="net-online". But this did no change in observed behaviour, so I removed net-online.
The info I found in the log.smbd with net-online in use and without:
| Code: | [2024/09/28 09:00:56.690164, 3] ../../lib/util/util_net.c:255(interpret_string_addr_internal)
interpret_string_addr_internal: getaddrinfo failed for name enp3s0 (flags 32) [Temporary failure in name resolution]
[2024/09/28 09:00:56.690201, 2] ../../source3/lib/interface.c:500(interpret_interface)
interpret_interface: Can't find address for enp3s0 |
Then I moved from the interfaces via "interfaces = lo enp3s0" to "interfaces = 192.168.1.0/24". This made it more critical, but I do not have an idea where to look next:
| Code: | [2024/09/28 09:08:15.394647, 2] ../../source3/lib/interface.c:603(interpret_interface)
interpret_interface: Can't determine ip for broadcast address 192.168.1.0/24
[2024/09/28 09:08:15.394688, 0] ../../source3/lib/interface.c:685(load_interfaces)
WARNING: no network interfaces found
[2024/09/28 09:08:15.438420, 0] ../../source3/smbd/server.c:1258(open_sockets_smbd)
open_sockets_smbd: No sockets available to bind to.
|
When I do a
| Code: | | /etc/init.d/samba restart |
after boot, then samba starts as expected is accessible via network.
Do you have an idea where I could look next to solve this?

I found that using the "bind interfaces only" as active setting causes the issue.
I now disabled it and samba works as expected:
| Code: | [global]
workgroup = Arbeitsgruppe
server string = Samba Server
# Logging, max 1MB log
log file = /var/log/samba/log.%m
max log size = 1024
log level = 3
interfaces = lo enp3s0
hosts allow = 127.0.0.1 192.168.1.0/24
hosts deny = 0.0.0.0/0
server min protocol = SMB3_11
server max protocol = SMB3_11
security = user
guest ok = no
[homes]
browsable = yes
valid users=%S
writeable = no
create mode = 0600
directory mode = 0700 |
I did not find a hint in the man pages or somewhere else, why this would happen.
At least for my use case it is solved  |

I think the issue in your original config is that you have the wrong address in the "interfaces" section. In my config I have the actual IP address in the 'interfaces' part. You have a generic .0 address.
| Code: | interfaces = 192.168.1.81/24 127.0.0.1/8
bind interfaces only = yes
|
Which matches:
| Code: | 2: end0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether d8:3a:dd:xx:xx:xx brd ff:ff:ff:ff:ff:ff
inet 192.168.1.81/24 brd 192.168.1.255 scope global dynamic noprefixroute end0
valid_lft 61571sec preferred_lft 47928sec
