OpenSUSE :: Lifecycle Management Server - Setting Appliance As Client?
Mar 1, 2011
I have downloaded and setup the SUSE Lifecycle Management Server on vmware using the Live CD Distribution. I have connected it to Susestudio.com as my repository and setup a user account via the backend on pg 96 using the slms-admin-ui-user -o to create my administrator account since I lost the password for the initial login. I created a customer and have the following:
Mirroring Credentials - User Name: (random character)
Mirroring Credentials - Password: (random character)
Also I have a test box for installing the Live CD of our application. Do all appliance created on suse studio have the client to connect to the SLMS server or do need to install a client? If there is no client how do I obtain and add it to the appliance on susestudio.com ? How do I setup appliance as a client?

I setup a server with vmware esxi 4. I installed opensuse 11.2 and I have successfully setup an internet gateway and I manually configured (static) my client IP. My question is, is there any software or commands that I could use to manage the bandwidth usage for each client? eg. only 5Mbps for 192.168.1.5, 10Mbps for 192.168.1.10, etc

I have been messing around with freenx to see if I can support my customer via remote desktop... I have installed the server on Ubuntu Karmic and the client on Windows 7. I love linux but need the windows computer for customer work and that is why I chose to install the client on windows. I setup the server the best I could and created custom keys which I then copied to windows and imported them to the freenx client. I am looking for security for my customer and that is why I chose custom keys... There are several issues to deal with but I want to just get started to see where it takes me. I added the test server computers ip address to the freenx client configuration and tried to connect to Ubuntu... I have left the port as 22 at the moment
Desktop setting on the client...I chose vnc which seems to be a good choice according to all the material I have been reading....Other settings I have left alone at the moment to see how things work.... All that said - I have the login window asking for information... I have the password asking for information....and I have the session wanting information....? Obviously I understand that login info can be set on the server and the password...but I haven't seen how to set up that? Of course I am testing the server from a client on my home network at the moment - but the customer has his own router as do I so those settings will need to be looked at as well.

I want to practice setting up of NFS server and NFS client on Redhat using virtual machine on my laptop. I dont think setting up NFS should not be a problem but how do I replicate a NFS client. I just have one laptop. Is it possible to replicate both server and client using the same laptop? If so, can anyone tell what tools i can use to perform the above for practicing.

I currently have 4 Linux Servers installed in a test lab that I have built for my job. I am in the process of trying to get FTP to work (vsftpd is installed). I don't need an FTP GUI or anything, I can use terminal (and I don't have an internet connection, so I probably can't get one anyway). I bring up the terminal and I type FTP and I am presented with a few problems:
1. If I try to FTP to one of the other Linux Servers on the network, I get "No route to host" error.
2. If I try to FTP to the Server I am sitting on, then I am able to successfully connect, obviously. But when I do an "ls," I don't see any available files.
I am assuming this is because I have not yet set up a folder for it (i.e. Windows uses "ftproot" folder). I am running Ubuntu Gnome 9.04 Jaunty Jackalope for a GUI, and I am running Ubuntu Server underneath (Yes I need a GUI for what I am using the server for).

I got a system with RHEL 5.3 Server with dovecot, sendmail, and thunderbird. I have found tons of stuff online about configuring a mail server, but little of it tells me how to get mail from a client to the server. I've tried to work with Postfix, Pine, Sendmail, Thunderbird, and the list goes on. I'm probably so confused now that I'm not even going to convey this properly, but let me try...... I got a system called wks90 which I decided would be my mail server. I installed dovecot, sendmail, and thunderbird. Then did some basic configuration via stuff I found online. Now the test, from the command line I use the simple "mail" command which succeeds. I bring up thunderbird and eureka!!! there is a message in /var/spool/mail/george.
Now here is where I get confused and things fall apart. I go to another system named wks50. I try some similar setup in sendmail trying to point it to wks90 as the server, I assumed dovecot was not needed, made and entry in /etc/aliases, and will use my thunderbird on wks90. So at the wks50 command line I mail -v to george@mydomain.priv. The message seems to work ok, but still goes to wks50's /var/spool/mail. How in the name of sanity do I get the mail to go to /var/spool/mail on wks90? OR somewhere that is centrally located. I tried to mount /var/spool/mail to wks50, but then wks50's mail to root started queueing up and going nowhere.
I guess I got the whole concept of mail wrong somewhere in my thinking. I just want the mail from any client to wind up at one server (wks90) and in a central location on wks90 so that any client like wks50, wks60, and wks70, using thunderbird, can read the mail from that central location. To me this sounds like I need to mount that central location to each client, but how do I then deal with the queuing root mail? Or is sounds like a need something like that old "movemail" command to take it and move it. I have another server that is the HOME server (server1). The physical location of all $HOMEs is here i.e. /home/george.

I have a fast computer in my office and I want the person using the slow computer in the same office to boot up and see the login window (gdm) and log-in from there into the fast computer and be able to use their session on the fast computer the same time I am locally logged in to the fast computer as a different user and session.Is this best done through XDMCP? Where is a good tutorial on how to set this up?

In 11.3, if in "/etc/sysconfig/network/ifcfg-eth0" i set DHCLIENT_SET_DEFAULT_ROUTE="no" this seems to have no effect. If i start my box, the routing table has the "default route"-entry offered by a remote DHCP-Server. More Info: My Susebox has eth0 and eth1 and both network devices should use DHCP4. But from DHCP-offer on eth0 i want to use
* "offered IP-Adress for eth0"
* "offered NTP-Server"
* "offered Host-Name"
From DHCP-offer on the eth1 i want to use
* "offered IP-Adress for eth1"
* "offered DNS-Servers"
* "offered Default Route"

I know there are ways to change the login of a linux box (runlevel 3) so that you don't see the regular login prompt but that you get a list with options. You see this with appliances.
My goal is to create a login like some of those appliances have. Instead of just getting a login prompt you can select several options like login, change network configuration, change password, stuff like that. How can I do this? Is there an Open Source tool to configure this?

I'm looking to setup pulp for patch/update managment. I've managed to install it OK, along with the many dependencies. I'm using CentOS 5.5 on a VMWare virtual machine.
When I try to start it for the first time, I get the following...
# service pulp-server start
Pulp database not initialized, please run: /etc/init.d/pulp-server init
...so I start it with the init parameter...
# service pulp-server init
Starting mongod: [ OK ]
[Code]....
...so it looks like it tries to start, and then gets a segmentation fault and shuts down.

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.

I am regularly keeping watch on kernel releases like 2.6.36-rcX and compiling the upcoming kernel releases on Fedora 13.I came across STP [URL] and PLM testing and seems like it is relevant tool for compiling, testing the kernel components in very precise way. I am unable to find the documents which can help in how to implement or run the tool. I have just downloaded the Test-suit tar and dont see any README or steps to test or run the tool.

until 2 weeks ago I had o.S11.3 on both my Siemens and Asus laptops. I have installed NX No Machine. ( I know it's not open source,I am using the free version). With commandline ( root) /usr/NX/bin/nxclient I was able to connect to the other machines. I got Qt: Locales not supported on X server, the NX menu popped up and I was able to connect by inserting resp codes. After fresh install of o.S.11.4 on the ASUS the commandline (root) answers:
xlib: connection to":0.0" refused by server
xlib: No protocol specified
nxclient: cannot connect to X server:0.0
The ASUS can still be reached from the other machines (one with o.S.11.3,the third one with o.S.11.2 ) SSH ( Lan)connections are all working forth and back between the machines, even to and from Win XP, however only from Win 7 on the ASUS, but that's a Win7problem. Comparing the installed xorg-x11- server-extra : on o.S. 11.3 Additional X servers ( Xmdx,Xephir,Xnest,Xvfb ) ,on o.S.11.4 the Xvfb is missing, might that be the reason?

So a while back I was able to mount a directory from my OpenSuse server as a NFS on an Esxi server. After restarting the Esxi server, the NFS became inactive and I was unable to remount it. The error given was that the Esxi client was unable to connect to the Suse server. I was looking into the showmount -a command on the Suse server and it showed the mount point on the Esxi server. Could this be causing the Suse server to reject new attempts to mount the directory? What else can I try to fix this problem? Also I should note that both servers can ping each other.

Background:I have a small PC104 running opensuse 11.1. I'm writing a small client/server application for debugging purposes using mono and WCF. All the client does is make a request for information every 100ms.Problem:After about 20 requests the server quits responding to the client. Even if the client is running on the same machine. I've run the exact code on another laptop running opensuse as well as a laptop running windows and everything works great. Hopefully that closes the option that it is a code, mono, or opensuse flaw.Is there a kernel option or a network option that anyone knows about that might cause this sort of behavior?

I setup an ssh server that works fine when using the terminal, but trying to run programs like firefox fails. It will open partially and then simply hang. Less complicated programs can open successfully and run fine, but cause my remote computer to pause every 5 seconds for about a second.

I bought a QNAP 219P NAS as it was Linux "Compatible" what it lacks is the instructions on how to install under Linux. I've set up the NAS on the network, have given it a server name, and can connect to it through my web browser, everything appears to be OK with it. What I can't do, as I'm new to Linux, is get the PC to mount the drive. I have installed nfs-common and portmapper through synaptic package manager and I run Ubuntu 9.10 64 bit. What is the setup so the NAS can be used by multiple clients (PCs) and is always there on logon.

I have a 11.1 NFS server and several 11.1 NFS clients. If for some reason the server shuts down before the clients then the clients become almost frozen, particularly KDE is rendered useless even after cycling back to init 3 then init 5. I would like to make the clients immune to shutdowns on the server.

I have installed a working DNS server on my home network. I have an unique server, devoted to dns, gateway, storage which runs opensuse 11.0 (I known that it is rather old). Two new clients require DHCP. I have installed, using yast, a very simple DHCP server, according to the following config:
option domain-name "XXX.XXX";
option domain-name-servers 192.168.0.1;
option routers 192.168.0.1;
[code]...
(I have tried to add "ddns-update-style none", and to remove the ntp-servers option, since my server is not a time server, without success). Unfortunately, even if the client (a mac running OSX 10.4) receives a right IP and gateway address, it displays neither dns server address nor default domain name. The same mac, on my office network (not managed by me), receives everything.

I'm trying to add the -audit option to X Server. I run ps -ef | grep -v grep | grep "bin/X" and get: root 2511 2506 0 10:35 tty7 00:00:09 /usr/bin/X:0 -br -verbose -auth /var/run/dgm/auth-for-gdm-sScn1P/database -nolisten tcp vt7 So I'm thinking that I need to add -audit to the /usr/bin/X file, but I believe that it's binary and created by something else, but I can't find that "something else". How on earth can I add this option? I have opened up 1,000,000,000,000,000,000,000 files (slight exaggeration) and I've come up empty.

I am trying to connect to an existing VPN server that I have been using for years now. I am moving my develpment environment over to a Ubuntu box and I must have openvpn working in order to access SVN. It has been a few years since I have been setting up linux boxes. And networking is a soft spot for me. But
The server has been running without problem for a LONG time. A windows computer I have been using connects to it fine and I can access the network on this machine. I am setting up a new computer, but when trying to connect openvpn starts the initialization sequence completes but I cannot ping the network I am trying to connect to.
I use a second VPN connection to connect to an alternative network and it works fine. The difference between these two is that the working vpn connection is a routed IP tunnel and the one that is not working is a bridged connection.
The VPN that is working on this box brings up tun0 while the bridged connection connects but does not bring up a network tun device. The server logs look normal, it just looks like the client is not setting itself up to use the network once connected. (The key/cert pair work find when on a windows box) Just not on this new ubuntu build.
My current client config
Quote:
cert eric@home.crt
key eric@home.key
client
dev tap
[Code]....
The server is using tap, as well as the working windows client uses "dev tap"
It has been a long time since I have been maintaining linux boxes but its coming back slowly.
Do I have to bring a device up manually ?
