I am failing to log in on a NIS client server. I input the login name and takes long to bring password prompt. It then gives an error :Login timed out after 60 seconds. A boot message also appears : No NIS server found when it attempts to start ypbind.
I am stuck since I need to correct the NIS configuration on the server. How do I login then into the server.

I have recently discovered the following: when I attempt to connect to any of our machines that are OpenSSH 5.x (Ubuntu 10 or OpenSuSE 11.x in our case) as one of the users defined in the NIS domain that fails. For instance, me (user bepstein) can SSH into all those machines but not SFTP.I can SFTP into those machines on the network that are OpenSSH 4.x, however (CentOS 5.3 - 5.4, OpenSUSE 10.3).As a user defined locally on the machine (in /etc/passwd ) I can connect via either SSH or SFTP even if the machine is OpenSSH 5.x.Some further discussion of that issue is available here: http:[url]....

New ubuntu desktop user here. I've been working with Ubuntu servers for over 3 yrs, using Windows as clients. I have OpenVPN running on an ubuntu 10.04 server, and it has worked well with Windows OpenVPN clients connecting. I took those same settings and applied them to this new install of Ubuntu 10.04 Desktop, and now openvpn seems to be failing when we get to the routes (I wrestled with the network-manager "secrets" issue for hours, but that works now).
I performed the following:
sudo openvpn --config fogbank-ny1.ovpn
--all is well, we're connecting/yay then *screech* FAIL--

I am using the suggested openvpn routes. If I connect from Windows (actually the .ovpn file is taken directly from the working windows machine).. all is well, routes work fine all traffic is routed thru the VPN -- same way it's worked for over a yar. I assume that this is what is causing networkmanager to fail as well. those logs indicate that it has connected to the vpn, but is probably stopping when it gets to routes.
I tried installing Ubuntu LTS 10.04 Server Edition 64 bit on one of my drives today...
The install completed fine until it went to reboot. Then it faills while initializing the graphics. It tries (a purple flash on the screen) then goes to a text based dump on the monitor.
Ubuntu LTS 10.04 Desktop Edition run great on this machine. I'm wondering if the Server Edition confused by multiple instances of a video card? This computer is SLI bridged:
Code:
Is the xorg or whatever video subsystem that the server edition uses different than Desktop Edition?
Now that I have setup a proxy server, as a next step I want to run it in fail-over high availability mode, so that if one proxy is down due to any reason, second proxy should automatically be up and start serving requests.

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.

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.

View 7 Replies View RelatedI'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

View 1 Replies View RelatedI am new to Linux and I am trying to set up a mail server using postfix. I have done all the configurations(hopefully correct) and all the test seems to work except 2 things.
1) Postfix is running but when I try to restart the service it always fails. I checked the /var/log folder and there are no error messages.
2) When I try sending e-mails using outlook, outlook fails to connect to my server.
I am wondering if I have done the configurations properly. I am a little confused in regards to hostname and domain name. When I do a hostname on the terminal I see the hostname that I gave my server. When I do the domainname command however, domain is none. Is it necessary to have a domain to configure postfix? I have myhostname = my.hostname.com what should my domainname = to if there is none. If I do require a domain name how to I create one? I need to be able to access e-mail from external clients.

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?
