Re: [Samba] samba and fail2ban
Hello, to stop bruteforce logins to samba i want to create a fail2ban-rule which blocks IPs with to many login-errors. unfortunately used logins and IPs in samba log are scattered to multiple lines so i cant find a relation. i use samba for wan and cant reduce to internal IPs. What ist best in my case to get better logs or stop abusing? nobody has an idea? is there no possibility to get logs which show which ip is doing too much false logins?

Re: [Samba] samba and fail2ban
Hello, Maybe have a script running in the background, parsing samba log file to create and alternative log file with all related info on the same line for fail2ban...? but problem will still be the same. How to find lines which belonging together? may be in log we have connect from 3 IPs a, b, c and following 1 successful login and 2 false. which ip belongs to the false logins? Every other server i know sends this important messages in one line.

Re: [Samba] samba not knowing new users
Hello, Is this server a PDC or standalone server? this is a standalone server Ubuntu 10.04 lts, simple samba-setup for inetusers. What is the backend for samba accounts? passdb backend = smbpasswd Do you create unix accounts first as well, or are you using winbind/idmap backend to allocate unix id's for the samba accounts. Do accounts show up with wbinfo -u ? we create the unix-accounts and after this we add the user to samba by smbpasswd -sa i can see all users in the smbpasswd file. hmm, i installed winwind, we dont use it but wbinfo -u shows all users incl. the users which wont work (NT_STATUS_NO_SUCH_USER) this is a mircale to me, only restart helps to get users to work.

Re: [Samba] samba not knowing new users
When you say restart do you mean the server or samba. i mean only samba, server remains untouched. Thanks, Hajo -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
Re: [Samba] samba not knowing new users
What do you mean users are in smb.conf? ok, this was wrong. i meant there are the correct sections for my users. How are you creating the users? Can you see the user or users with pdbedit? i can see the users in my smbpasswd, but if i use pdbedit -L there are only a few users listed. i have to ask my buddy for errors when creating the users because this is done by script. after restarting service smbd my missing users are immediately able to log in but with pdbedit -L they are still not shown. so iam in doubt if there is an error when creating the user, but i will try to get further information.

Re: [Samba] samba not knowing new users
so iam in doubt if there is an error when creating the user, but i will try to get further information. so, getting back with this information: script is adding sections to smbd.conf, creates systemuser by useradd and finally it is creating the samba-user by smbpasswd -sa my buddy tells there is no error etc. what could be the problem that some new users only work after restarting smbd service? it happens not every time...
