Server (Centos)(Firewall with 2 nic), which makes access to the net, with only 196MB RAM (PIII500Mhz), so I do not want a solution based on proxy or what resources it uses large I want a solution with a script that runs at login on windows this check series HDD and to communicate with Linux server that's open accessor another simple solutionNow just use only MAC filtering on

This is the script I use at boot
Code:
#FOR SHARED INTERNET
/sbin/iptables -P FORWARD ACCEPT
/sbin/iptables --table nat -A POSTROUTING -o eth2 -j MASQUERADE

I haven't test it with windows xp station but I have use the same code in the past with no problems, and since this is my first time joining windows 7 station i belive there must be some other port that need fowarding.
Samba up and running on my pc. pc runs FC12 with kde. A laptop has win vista. The pc can access the shares on the laptop but the laptop has authentication issues to access the pc. Note that windows doesnt enforce authentication forincoming network connections.Using the system-config-samba util i tried to map a windows user to the unix user "feduser". The laptop (named LAPPY) has a user (lapuser) which has on windows no password.What should I tell samba config what the windows username should be? lapuser or LAPPYlapuser doesnt work because when accessing the pc via the laptop, the authentication fails. The only auth that is successful is when choosing the same winusername as the unix username.
Secondary, id like to setup the laptop so that the user doesnt have to provide a name and password, or at least not more then once in the lifetime of the laptop. Note that you cant provide an empty password to system-config-samba. How is that possible?
Strange but not really on issue imho:the samba - KDE control module(kcmshall4) (and the smb.conf) shows 2 shares: the homedirs and the data dir the samba server configurator (system-config-samba) shows only the datadir.
I'm establishing a server that runs DHCP server, NAT gateway and VPN server. It have two physical interfaces, one for intranet and one for internet. The NAT gateway will give internet access for intranet. Another site will connect to this server by VPN. I need the server to assign a different subnet for that site other than the local site. Do anyone know how to config the DHCP server? Should I config the client classing, and how to do it?

View 5 Replies View RelatedI work as an system administrator for AIX and Linux servers. We have an FTP server running in Linux which has shared folders to Windows domain using Samba. The new requirement is to map users created to Linux machine to Windows users in such a way that, when a user logins into Windows machine with an ID say "X123" in domain "TEST", his access control to the samba shares should reflect based on the same user ID created in Linux machine.(FYI. Both the Windows and LINUX machines are in same network and domain). Please let me know the step by step procedure to configure Linux machine (smb.conf entries or any new file to be created for user mapping) to identify Windows user Login and provide access restrictions accordingly.

View 10 Replies View RelatedIn other Linux distros I've used, new users are assigned to their own group (i.e. user 'joe', group 'joe') by default. To my surprise, when I create new users with my openSUSE 11.4, they are all assigned to the 'users' shared group by default.To test this, I created a new user called 'friends'. From my terminal, I can see how the new user files look like:
joe@linux:~> ls -l /home/friends/
total 40

View 1 Replies View RelatedI have inherited a RedHat 5.4 server that is having an odd issue. Root and all of the user accounts can log in via SSH. Not a single account can log in via the console (sitting in front of the server). If I bring it up in single user made, I can log in with root all day long.
I want to say that this has something to do with PAM, but this is when I play my "Noob" card. Could anyone possibly steer me in the right direction to figure out what is going on?
Im not getting able to neither add new users using command useradd nor delete existing users using command userdel. And even Im not getting able to login into any existing users except root. It was ok before. Im having this problem very recently on my linux server. Im using RHEL5.
View 9 Replies View RelatedIm trying to config my intranet to be accessible from inside the network (lan) without need of password and ask for a passwd for those who are viewing from Wan ....
Today my intranet can only be accessed from Lan, external access give me an Unauthorized message, I took look around, try #irc and still can get the appropriated help, I hope that someone here could help me on that...
A piece of my config:
Code:
Let's say I have a directory called dir1. In it, I have these files: A1, A2, A3 belong to user "userA", files B1 and B2 belong to "userB". Both users are in group "groupNO", but the files are in group "groupYES".What I want is this: if someone tries to mount the folder by NFS (or could it be done withSamba?), as userA, they can only see (or read) files A1, A2, A3,as userB, they can only see (or read) files B1 and B2,as a user in groupYES, they can see and open all the files.This is just the principle. If I need to sort them into directories or use another program on the server-side, that's fine with me. I just want the user to just have to mount the folder over the LAN with a user name and password. I'm fairly sure I can do it by SFTP, but, again, I want the client to be able to MOUNT the folder on their local machine over the LAN no to user a special client.Is that possible? Do I need LDAP? (From what I understand, LDAP is separate from the OS-level mounting process, which is not what I want.)

View 3 Replies View RelatedI have an Openldap server and many 9.10 servers using it to check for possible ssh users. No problems there. Just brought up my first 10.04 server and went through the same procedure to allow ldap users to ssh in, works great. The problem is that ldap users cannot su to root on the 10.04 server. Only locally defined users can su to root, though they cannot su to ldap users. The local root user can su to anyone. Quick overview of how I installed ldap login:
Code:
# apt-get install libnss-ldap
# echo "session required pam_mkhomedir.so skel=/etc/skel/" >> /etc/pam.d/common-session
And added ldap to the end of these lines in /etc/nsswitch.conf:
Code:
passwd: compat ldap
group: compat ldap
shadow: compat ldap
This process has worked without a hitch on 9.10 dozens of times. So my question is, why are ldap and local users now incapable of using su across authentication mechanisms? For reference these are the error messages in /var/log/auth.log when trying to su to root from an ldap user:
Code:
Jun 14 16:17:07 server unix_chkpwd[6560]: check pass; user unknownJun 14 16:17:07 server unix_chkpwd[6560]: password check failed for user (root)

Jun 14 16:17:09 server su[6559]: pam_authenticate: Authentication failure
Jun 14 16:17:09 server su[6559]: FAILED su for root by ldapuser
And the auth.log for trying to su to an ldap user from a local one:
Code:

Ubuntu 9.10 So I have four boxes. One has all the users on it and it is the nfs-server. The other 3 are nfs-clients. I need to be able to share all users between the boxes. I have mounted the /home directory from the server onto the three clients as well as the /usr/local folder, however I am still unable to log in as anybody but the root on the clients.
I am not even sure how to search for this (I keep getting results on how to mount the home directory, and information about adding multiple users to a single box).
I would like to block downloading for my LAN users through squid or other.
