Samba failed (Error NT_STATUS_HOST_UNREACHABLE) [Solved]

Post by nomorelogic » Mon Feb 20, 2017 15:31

hi all

I've some problems when working with samba.
smbd and nmbd are started but I'm unable to connect with smb server.

e.g. using smbclient, I get this error

Code: Select all

# smbclient -L //10.4.4.87
WARNING: Ignoring invalid value 'share' for parameter 'security'
smbclient: Can't load /etc/samba/smb.conf - run testparm to debug it

Connection to 10.4.4.87 failed (Error NT_STATUS_HOST_UNREACHABLE)

Have you turned your firewall off to check if that is the cause?

If you are using Samba on a home network and it has around 15 or less devices, you don't need to use WINS at all; broadcast NetBIOS name resolution works fine on a home network: A correct method of configuring Samba for browsing SMB shares in a home network

about firewall: It's a fresh installed sabayon with kde, I never enabled a firewall, how I can check if firewall is on? :oops:

I'll read your link for home share.

thanks
