Networking :: Client Tools For Testing And Configuring Boot Server
May 12, 2009
I am trying to set up to serve Linux kernels and filesystems disklessly, and find the startup and test procedure a bit tedious.Can anyone point to a tool or tools to allow me to see what is going on with my DHCP/TFTP/PXE setup, which I'm trying to get working? Ideally, I'd like a tool that can do something like grab an IP from a DHCP/BOOTP server, tell me all about all that it found, and then if it was told to download a file, it could do that and tell me about how that went, and so on. Between the information reported by the tool and the droppings left in logfiles on the server side, I would hope to simplify the configuration process, as well as let me experiment with various options, etc. Even a PXE client tool that I can use to exercise my tftp PXE server configuration from a shell commandline would be extremely useful.If no such tool already exists, would anyone else find something like this useful?

I've been busy with configuring Samba with the 389-Directory Server (former Fedora Directory Server) for the past weeks and I almost have everything working. The last thing (I hope) that I haven working are the smbldap-tools which I'd like to use for adding computers and users to the domain. The part where I'm stuck is with the security certificates. I don know how to get the client certificates out of my installation.
My smbldap.conf file contains this:
Code:
# $Source: $
# $Id: smbldap.conf,v 1.18 2005/05/27 14:28:47 jtournier Exp $
#
# smbldap-tools.conf : Q & D configuration file for smbldap-tools
# Purpose :
# . be the configuration file for all smbldap-tools scripts .....
I used the setupssl2.sh script to setup ssl for my 389-ds, which seemed to have worked fine. I however simply have no clou how to get client certificates out of this.

how to make a new Ubuntu 9.10 box use our LDAP/Samba server for user authentication. Our Red Hat and Windows machines all use it just fine. I've been trying to use the auth-client-config and libnss-ldap packages for this purpose, but I must be missing something. I'm pretty green with LDAP, so this is my first time diving in... Is there a good How-To or step-by-step read on this? All of my searches lead me to setting up Ubuntu as the server, and that isn't what I want. I've also tried the steps listed in [URL] for the LDAP Authentication section.

I would like to test network performance, to get statistic information. Is there any tools where I could specify partikular message size send as a constant for many times and in an output I could get time for each transaction? There is a tool called ApacheBench, it is for webserver testing, but I would like to find something similar for network testing. I have also tried Netpipe, Netperf, Iperf, but they do not show information in an output, which I would like to see.

I am looking for tools for static/dynamic code analysis for embedded Linux system development (both device driver and user space apps) with ARM-based processor. We use Eclipse IDE and C++ lanuage for development. Does anybody have recommendation for tools to analyze code complexity? The tools is better to support McCabe complexity metric, however, we may also consider others. Does anybody have recommendation for unit testing?

I'd like configuring NTP service on my Lenny Debian client to retrieve time from my local NTP server, so I thought to configure /etc/ntp.conf and to insert into crontab this command 'ntpd -qg', which is indicated in man. Can I run ntpd service to synchronize time for my client, avoiding to listen on port 123, beacuse my scope is to alignment time on client and to not give service to others, for this scope there is ntp server !

I'd like to configure Evolution (or Thunderbird) to delete Gmail messages. When I select messages and hit "Delete", the messages go to my local trash and they loose their Inbox label in Gmail. I would like that in Gmail, they loose their Inbox label and go to [Gmail]/Trash so that they'll be deleted after a month.
Could I configure the "delete" key of my keyboard to move msg to [Gmail]/Trash ? Could I configure another key to move msg to [Gmail]/Trash ?
What other solution ? Because moving to the trash is not convenient, it takes a lot of time without a key shortcut.
[Code]..

I am trying to setup a HP blade (BL460) server with 2 nics on sles10sp3. I want one nic to connect to a management vlan and and second to connect to the standard network. It should be possible for a desktop in the standard network to connect to either nic by providing the correct ip address.use this server as our first virtualisation hosts server using Xen. I dont want traffic used to upload / download images to the server through nic1 to effect the users traffic on the standard network on nic2. However any attempt at routing (which Im not good at) has led to the tx traffic all going out the default route (users subnet).
Each time I setup the nics via yast2 lan I can get the standard lan nic working ok. but cannot get the management nic working correctly. The server can ping a workstation on another vlan, but the workstation cannot ping the management nic. The default route appears to be forcing all traffic on the host out through this route, which I presume is normal behaviour. Using tcpdump I can see the ping packets received by the server, the server then responds through the default gateway, which the workstation does not see.
However, this normal behaviour will result in extra traffic on the users network when image downloads are initiated from the management interface.If I use a 172.24.1.0 network routed through 172.24.1.1 router setup as our management vlan , and 200.200.1.0 with router 200.200.1.1 as our lan for general users. Where server ips are nic1 10.1.1.10 and nic2 200.200.1.10 My workstation would be 200.200.1.10. If I ping the server at 10.1.1.10
I get no response. If I ping the server at 200.200.1.20 no problem.
Basically I used the network setup recommended by vmware to manage a virtual server. I actually have 4 nics, I thought by just talking about 2 nics the problem would be easier to explain. vmware specify that two nics should be used for management and two for the Lan. This is what I am trying to achieve, but both subnets must operate independently.

I am trying to install and configure LTSP on a server for a HP thin client to boot off. The version of Ubuntu that I am using is 11.04 x86 and it is a fresh install on a dual core system with 2GB RAM. I followed a guide which comprised of these commands.
sudo apt-get install ltsp-server-standalone openssh-server sudo ltsp-build-client or if your on a 64-bit system with 32-bit machines do sudo ltsp-build-client arch i386 for editing the servers IP values use /etc/ltsp/dhcpd.conf after that you need to restart DHCP server sudo /etc/init.d/dhcp3-server restart
and update sshkeys -sudo ltsp-update-sshkeys and if you updated dhcpd.conf then you need to update you image also by typing in terminal ltsp-update-image
Everything seemed to install as it should but when I try to boot from the thin client it just times out and says no DHCP or proxy invites received. I turned DHCP off on the router and even tried another router, but I still get nothing. I am at a bit of a loose end and I hope someone on here can point me in the right direction of where I am going wrong.

I have a wireless router situated in another room. I am able to access this router (and consequently the internet) through a Windows laptop that has a wireless card in it. However, my other laptop that has Ubuntu 10.10 installed on it, doesn't seem to have a wireless card in it, and I have confirmed this by running the commands
Code:
lspci
and
Code:
iwlist scan
I briefly was able to share a folder in my Windows machine, and access it through my Ubuntu machine, after connecting both laptops with a cross-over cable. However, I can't even ping the Windows machine from my Ubuntu machine anymore, after trying to configure the IP addresses. I think I screwed it up.
Also, although this is not an Ubuntu issue, I have a weird Windows problem, where I can't access the Internet when both wireless and wired ethernet controllers are active at the same time. It would be a bonus if you could solve this problem too for me. I was surfing online for a solution to this problem for quite some time, but I was unable to comprehensively understand and implement what I browsed through. Also, some of the guides, like for example, that on configuring Samba, seem to be outdated, as the terminal tells me something like the package (that was required to be installed by the guides through sudo apt-get install) has been superceded. Hence I post here for clear, concise and easy-to-understand help from you gurus. It would be great if I could achieve the end result of being able to access the internet on my Ubuntu machine (through the Windows one).

I'm trying to setup a linux box to act as just a DNS server. Its something I'd like to use just for WAN type requests and leave other domain related things to the Server running WIndows.At this point on my Linux box, I can run queries and nslookups from it. I can not however, from a Windows box, run a NSLOOKUP command from the Linux box which is telling me to check the permissions from Linux to enable that for the clients. It's enabled.From a C: I type in nslookup - *ip of Linux box* and it tells me -- Can't find server name for address.
