Ubuntu :: Web Server - Setup Model And Need To Give Computer Some Capability To Act As A Server
May 19, 2010
I want to set up moodle and need to give my computer some capability to act as a server. I am following the steps at [URL] although my question is not really related to moodle. Here is the problem: setting everything up to make my computer accessible from outside has worked so far. I got myself a static IP address using a dynamic dns server and can ssh into my computer from any other computer connected to the www. So,

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'm going to start a new thread because previous searches have not totally satisfied my question. I've read all day about doing this but each inquiry leads to discussion of configuring the router. I am also not network savy. I would like to set up an FTP server on my home computer (presently Ubuntu 8.10). I have only one computer. I am using DSL with my telephone line for internet connection. I do not use a router.
Is it possible to do this with no router and only a DSL ISP connection?

I'm trying to setup a vpn server so I can use my computer via phone. My phone only supports pptp, l2tp and l2tp/ipsec psk. I would like to surf the web, browse files etc. I've been using this guide [URL] but get stuck on the part.
Finally, disable and re-enable ufw to apply the changes:
sudo ufw disable && sudo ufw enable
I get the error:
ERROR: problem running ufw-init
So is there any simple way to get a vpn working on this thing? Or at the very least an in-depth guide that covers what would happen if something goes wrong.

What is a good MTA (e.g. Postfix or something else) setup for a home computer behind a NAT, or a laptop that is not always online? I've read a lot of Postfix tutorials on how to set it up this way or that, but they are usually geared towards computers that are servers ie they
have a static IP
have a domain name
are always connected to the same network
My requirements are, I guess: Ability to redirect mail for local users to another server of my choosing. No listening for incoming SMTP connections - outgoing only Ability to route outgoing mail via an external SMTP server with authentication (and perhaps encryption) If not Postfix, I need an MTA which can queue up mails in case it temporarily has no internet connection.

for christmas my parents got both my younger sister and i acer mini computers, model d250-1958. my sister was trying to change her password that lets herself as a particular user log in. somehpw she messed up the password and its not what she thought it was and now she doesn't have any way of accessing anything. i thought that there might be an ovveride system or a reseting trick. i've looked in the manual but cant find anything of the sort for either of the two options.

I'm trying to setup an Apache server on my computer which will allow browsing of files in a specific directory and subdirectories, without needing any sort of authentication.
I've got the Apache2 server up and running through yast, and everything works fine as long as I try to point it to the /www/htdocs folder. However, I want to point it at another folder, which is on another partition. This partition is formatted as NTFS, if that matters at all (here's some background on some permissions issues I had with the NTFS partitions recently).
When I change the "Directory" setting in the Yast http server configuration utility to the directory on the NTFS partition I wish to use, attempting to access the server results in the following error:
Code: Access Forbidden: You don't have permission to access the requested directory. There is either no index document or the directory is read-protected. If you think this is a server error, please contact the webmaster.
Error 403

We are trying to set up a NIS server on a CentOS system. We need to have a NIS server which can provide NIS authentication to a couple of clients. We are practically new to all this stuff.
Just googled to find some ideas about installing ypserv and ypbind and portmapper. We did all that and also started them successfully. But now the clients are not able to join to the NIS domain . The error log states "YP_DOMAIN NOT BOUND".
I guess we have not entered the /etc/yp.conf, /etc/hosts files properly. Please let us know the detailed steps to setup a NIS server .
Also, please let us know what entries should go into the different /etc/<file_names>? What is meant by HOSTNAME in the /etc/hosts file?
Is there any other files which need to be changed? Are we missing any steps?
Also to add-on, while executing the ypinit command we faced the following error:
At this point, we have to construct a list of the hosts which will run NIS servers. localhost.localdomain is in the list of NIS server hosts. Please cont inue to add the names for the other hosts, one per line. When you are done with the list, type a <control D>. next host to add: localhost.localdomain next host to add:
The current list of NIS servers looks like this:
Is this correct? [y/n: y] y
Error running Makefile.

I am currently developing an small program in Python and at a certain point, I need to do some "stuff" depending on the monitors that are connected to the computer. I have an intel vga card with two outputs. I want to do something if one of the screens connected to the output is a "Dell", another something if one of the monitors is a "Nec" and another something if both monitors are connected.
So the question is: Is there any way to get the vendor/model of the monitors currently connected to the computer? I did a little bit testing. I plugged both screens to my vga card (the Nec to the HDMI output and the Dell to the DVI output), and the gnome-display-properties tool properly detected the model, size, resolution... of both screens connected. I would like to know if I can use a command on bash (or a library in python) to get the same information.
The /var/log/Xorg.0.log also shows properly:
(II) intel(0): EDID vendor "NEC", prod id 26345
(II) intel(0): I2C device "HDMIDDC_C:E-EDID segment register" registered at address 0x60.
(II) intel(0): I2C device "HDMIDDC_C:ddc2" registered at address 0xA0.
(II) intel(0): EDID vendor "DEL", prod id 41027
I could always parse that file, but it is not the best solution. I also tried the ddprobe command, but for some reason, it only detects one of the screens (the Dell, connected to a DVI cable). I am currently using Ubuntu 9.04 and Python2.4 (just in case it's relevant).

I have a few friends that have seen me bypass firewalls with a socks proxy (SSH). I explained on how it works and how secure it is for browsing the Internet and checking your email in public places. I had at least 6 asked me if I could set up an account on my server for them and they would pay me! Now what I wanted to know was how I can set this up in a server and website where they can register an account and pay me through PayPal! I don't need help setting up the site! Just on how to set up the server to automate this. What tools are needed (ex. ISPConfig, jailkit.... stuff like that?) I don't mind doing this manually but if I get more people that would like this I don't really want to do every single one.

I'm writing because my ubuntu server has started with troubles .
It's running Linux 2.6.32-29-generic-pae kernel for ubuntu server 10.04 and after the last update it stopped from giving addresses on clients connected.
Dhcp3 server it's running and the conf files are fine, but i can only use static addresses assignation now...
Also MYSQL has stopped working (installed for Bacula purpose) but now the dhcp problem is the biggest issue. I work in an office where dhcp is fundamental, too much clients (about 15) that are personal laptops also (so static assignation for clients is not a good choose).
Please any one could help me? It's two days I'm trying to figure it out without success.
also tried removing and reinstalling dhcp3-serer...no way.
Here are my conf files code...

I set up a ubuntu server 10.04 lts as file server in a network filled with xp, win 2003 and win 2008.
I noticed that if from any bill's SO machine i copy a file (for example a vob file of 1gb, or a lot of doc and pdf files) in the samba server, while the copy is in progress if in another windows I browse other folders shared in Samba, the copy process stops and say ' the name in the network is no more available( or something like this). It seems that samba pay attention on the fact that a user is browsing the share and doing so it seems that Samba forget that in one of its share there was a copy in progress, very annoing. A file server cannot do that, in this way is useless.

If you hadn't guessed it from my last 3000(ish) java-related posts, I'm a Java n00b writing a Java Applet for a work project. I got to the part was I was about to write the applet code that would send HTTP requests to my CGI scripts. But I read some paragraphs in a book praising Java servlets as better that CGI because they are easier to use and give much better performance server side. My server load isn't very big, though, and I was wondering if it would be worth taking the time to learn about Java servlets and how to set up the server side configuration on my Fedora web server.

I wanted to know how can I cross compile SMS SERVER TOOL for an embedded computer and make just one binary file for it or how can I change all of its default files places like its demon and object file and gather all of them to one directory to execute and use and run.let me explain it better for you : I have an embedded computer with Linux OS that its file system is read only and I can not add any file to /usr /lib and ..... and I can just mount a SD memory card to it and copy all of my programs to it and run them from there as you understand I have two choices to choose, first make one big binary file for each program that I am doing it now and it is not a suitable solution and the second is finding the way to change default place of shared object file of my program.now you tell me what can I do to solving this problem.
