CentOS 5 :: Openldap Client Won't Bind To Server

Jul 2, 2011

I can't get the client server to authenticate to the openldap server. I can authenticate on the server itself though. I can su to, login and shh into the openldap server and become a ldap user. I just can't become an ldap user on the client.I didn't setup TLS/SSL. I can do that after I have it working. I'm using hashed passwords though. I don't have replication setup. I'm am tying to setup the most basic openldap environment then build from there. I have read the openldap section in the admin guide.

My setup at home.

Openldap server � light.deathnote.net -- 10.0.1.21
client server � vm-centos01.deathnote.net � 10.0.1.7 -- VM on virtualbox
Virtualbox host � L (OS MAC) � 10.0.1.2
router (apple airport extreme) / default gatway � 10.0.1.1

All computer can reach the internet and ping each other. When I installed centos I disabled SELinux.I used these guids to setup my openldap.

[URL]

Below I have included some output from the files I'm using with openldap.

[root@vm-centos01 ~]# tail /var/log/messages
Jul 2 09:25:33 vm-centos01 xfs: nss_ldap: reconnecting to LDAP server (sleeping 16 seconds)...

OpenSUSE :: FIrewall Setup / Client Computer Cannot See NFS Server When Scanning For Server - OSE 11.2?

Apr 21, 2010

I have a small home-office network. On that network I have two linux computers, one is a client the other a server.

On the server I have NFS Server setup and mount some NFS exports on the client computer.

On the server I have the firewall on and here it becomes a little tricky.

Since both the server and the client connect to the router the interface (eth1) is theoretically both an internal & external zone.

The router is commercial grade and therefore has a good firewall on it which is also setup. Therefore the firewall on the server is really more of a backup than a necessity. But that's fine, and by having the server's firewall on 'fail2ban' is able to work which I like to have working so I don't want to just turn off the server firewall even though I have good security from the router.

However, when I turn on the server's firewall, the client computer cannot see the NFS server when scanning for server -- done by: clicking on "Choose" next to "NFS Server Hostname" when adding an NFS share in the NFS Client in YaST. Clearly something is being blocked even though I have both "NFS Client" and "NFS Server Service" allowed in the server firewall. The Firewall config. files for these are below.

The Firewall configuration is pretty much "out of the box". That is I have the services I need opened up for the external zone, the other zones are left at their default which means the internal zone, although not used (i.e.: attached to any interface), is completely open.

The perfect solution I guess would be to setup my client computer to connect through a different NIC (perhaps eth0), make that the "Internal Zone" and therefore allow all traffic through to it while still blocking the server from the external zone. However, I cannot make that physical change to my network for now so I am looking for an in between (non-perfect) solution.

In this case I am guessing that means opening up extra NFS ports to the external zone so I have full NFS functionality. I don't mind this because like I said, the router firewall is the main line of defense anyway.

So, given all of the above could someone tell me what I would need to additionally open up in the server firewall to make the NFS server detection work on the client while the firewall was on. Or, if you have a cleverer/better solution without me changing my physical network that would be great.

Hopefully I have written this in enough detail and clearly enough so that all the parameters are clear but if not, feel free to ask me what you like and I'll try to make it clear.

Code:
## Description: Firewall Configuration for NFS kernel server.
#
# Only the variables TCP, UDP, RPC, IP and BROADCAST are allowed.
# More may be supported in the future.

Server :: Set Up A Program Or Application Online To Be Used From A Client Computer?

Apr 20, 2010

Is there a way I can install a windows program to webspace and run it from a linux client computer? To specify, I'm a student at the University of Minnesota. I have access to linux machines running Ubuntu, however, the space allocated to us is too small for the program I would like to run on these computers. I do have webspace I can use though. The thing I'd like to be running on the linux computers is a windows application requiring installation. So is there a way to put/install/(whatever else it might be called) this program onto my webspace and be able to run it from the linux computers? I know it's probably unlikely, but maybe?

Server :: BIND Server Test Not Answering Authoritatively?

Jun 14, 2010

I have a BIND server that I'm setting up with different views. There is another server out on the public Internet that currently handles all inquiries for this domain. I had installed the Yum packages, chroot, etc. and edited the config files by hand. When that didn't work, I erased the server and started over using Webmin to build everything for me. Same result. I want to setup and verify everything is working on this new server before I take it into production.This is in /var/log/messagesQuote:

Server :: BIND Server No Longer Working

Jun 8, 2011

I am still quite new to all this but I guess we were all beginners once, this forum seems very helpful.Here is my situation, I will give as much detail as I can.I have a dedicated server which is running CentOS release 5.5.Initially I had Plesk installed, but when I upgraded PHP I damaged the Plesk configuration, and so I installed Webmin instead.

All seems to be fine with this, apart from the DNS configuration / BIND server.I know this because I have one site which uses an external DNS server and this works fine (i.e I can access it from a browser). All the others don't resolve - i.e the ones I set up in Plesk.I've done a bit of investigating to see what is going on, but I'm stabbing in the dark a little.

Server :: Calling Remote Apps On Windows Server From 'buntu' Client

Apr 23, 2010

My desktop is running 'buntu 9.10 and I have recently aquired a couple of half decent servers running Windows server 2003. I have a few windows app's that I use regularly for work that I have had limited success in running with wine or in vm's. I stumbled upon a how to to call apps in a vm to run seamlessly on the host desktop and did some playing and have succeeded in calling app's on my servers from my 'buntu desktop, the command I have set in my launcher for one of them (DIALux)

My question is, can I change the default application/file association in 'buntu with a custom command so I can double click on a file and have it open in one of these remote app's??If I can, what is the correct custom command to be using as using the above doesn't work at all, it just tries to open the file with rdesktop not the remote app.

Server :: Run An Openvpn Server On A Openvz VPS - Packets Doesn't Reach The Client

Oct 23, 2010

I'm trying hard to run an openvpn server on a openvz VPS, the problem is packets sent from openvpn server process, doesnt reach the client, so connection is never stablished (I run tcpdump on server and wireshark on client to carefully investigate whats wrong), the first guess is that a kind of firewall is blocking traffic (I tried connecting to server through different ISP's but it's possible the national network provider applied some filtering but it cant be on IP,src port or dst port as I'd tried different configuration.

what about deep packet inspection technics, is it possible to block my traffic?) but at exactly the same time I can transmit UDP packets using netcat from server to the guest. there is no firewall enabled in between, I had tried, tcp and udp, tried both open vpn and openvpnAS and tried any thing one can imagine! the VPN is configured as a routed (TUN) type on debian

Ubuntu :: Terminal Server Client And Server 2008?

May 18, 2010

I love Ubuntu and last night I wiped crappy windows 7 off my laptop and installed and customised a beautiful Ubuntu 9 OS ( I tried the new 10.04 first but it had some issues for me ). Now, up here at work we got a Domain Controller that is running windows server 2008, I need to be able to RDP into it and mess with it, I tried to use the Terminal Server Client that comes with Ubuntu, and I can see the login screen just fine, but when I try to log in it says incorrect password and wont go through.

Just to make sure it was not my account that was the issue, I went to my boss and used his computer (a MAC running OSX) and I was able to get into the same server with the same credentials, so it has something to do with my computer not my account. Do any of you have any ideas on what the problem could be?
