Server :: Setup A Simple File Server With Mandrake 10.0?
Jul 19, 2010Gentlemen/Ladies; I checked the existing information on this site and found that it is pretty widespread and confusing to me. I am a Linux Newbie so please be patient. I use Mandriva Linux 10.0 and want to setup a simple file server. I also want to connect a Windows XP computer to access files on the Linux server. I have a spare router I can use. My ultimate goal is to learn MySQL and PHP programming; I am pursuing a Web Development curriculum at a local University but am just starting out.
Am I making sense and can I do it with the equipment I have? Can you point me to some resources,documents, etc. I can use to accomplish this?
General :: Manually Closing A Port From Commandline?
Apr 6, 2010I want to close an open port which is in listening mode between my client and server application. Is there any manual command line option in Linux to close a port ??NOTE: I came to know that "only the application which owns the connected socket should close it, which will happen when the application terminates."I dont understand why it is only possible by the application which opens it ... But still eager to know if there is any another way to do it ??

Jul 17, 2010I just installed Mandriva 2010 and set up the interactive firewall via the MLCC. I set it up not to allow any services to connect (didn't check any boxes). However, when I check my system using a port scanner (shields up at www.grc.com) it says that port 23 is open. Does anyone know why this would be and how I can close it When I look at the daemons running I notice that iptables and ip6tables are 'stopped' although shorewall is running - is this correct? I (perhaps wrongly) thought that iptables needed to be running in order for the firewall to work properly.

Server :: Telnet To Smtp Server Is Closing Immediately?
Apr 18, 2011I've configured postfix on my linux server. For the most part, I got everything working (IMAP, apache, etc) but for some reason, I can't get postfix to work remotely. Postfix works locally to send mail. E.g. when I telnet locally to port 25. However, when I try to telnet from outside, the connection closes almost immediately. I've looked at various configuration options and tuning enhancements but found nothing helpful. Here is my config:
Code:

General :: SFTP Server Port Blocked On Uni Network / Need To Change Listening Port
Oct 21, 2010VERY new to linux, erm but I have an issue that needs solving!I recently moved to university, where their network blocks sftp port 22, this means that I cannot connect to my FTP server which is running a version of linux.Now I've got this ftp server connected to a seedbox and it was created using the following walk through..Code:I have written this guide for a friend, but I though it would be useful for others as well.
There are several guides floating around, but I found that most always cock up in some way. This one is tried and tested to work on Debian Etch (on an OVH rps, but should apply to most servers).If there is a new stable release of rtorrent/libtorrent then I will update this guide to show you how to update it (without reinstalling the whole server).
At the bottom there are also instructions to install ftp access & some network monitoring software.Basically, I would really like someone to be able to construct the commands on how to change the listen port for sftp connection on linux or add another port to the list that Linux would use so that I could put in through putty.

After entereing: $ tar xvjf firefox-3.6.tar.bz2 on my linux box: [GCC 3.4.1 (Mandrakelinux 10.1 3.4.1-4mdk)] on linux2 the end result comes to nothing.

General :: Installed Mandrake \ Can't Connect To Internet?
Apr 6, 2011I have just installed Mandrake Linux and everything seems OK apart from the fact that I can't connect to the internet. I presume it's because I have not got the relevant driver (or have not configured it if it's there)y machine was previously running Windows and all the disks I have are for Windows.I have looked in my manual and it says I have a K8NBP GRAND (I think that's the motherboard, you'll see that I don't really know a lot!!) The manual also says Gigabit Ethernet LAN : NVIDIA Gigabit MAC + VITESSE Gigabit PHY - Supports 10/100/1000Base- T Ethernet/Fast Ethernet/Gigabit Ethernet.When I was running Windows I just had a network cable running out of the back of the PC connected to one of the LAN sockets on my routerI am currently having to use my wife's laptop (which runs on yet another OS but at least it connects to the internet or I'd be really stuffed).

Software :: Corrupt GUI - KDE - Only On Cold Boot - Mandrake 10 - Weird ?
Apr 14, 2011Summary: Video fault on boot when KDE starts, but only after being shut down properly and turned off. Rebooting yields a perfect boot, removing power while running yields a perfect boot.
I'm working on a very strange problem for a client and I think I've hit a brick wall. In a nutshell, when the system is booted up all indications are normal until the GUI starts. I briefly get an hourglass on a black background (it's normally blue) and then just a black screen with a corrupt line of randomness across the top of the screen. The weird part is that this ONLY happens after the system is shut down and turned off.
If I kill power after I get the corrupt desktop, it will boot into KDE just fine. Also, if I reboot instead of shutdown it will boot correctly.
For now, I've told them to boot up until it freezes/corrupts video and then perform an alt+SysRq+REISUB to reboot into a usable system. After that it works as expected, so they basically just have to start up and then reboot if they ever turn the equipment off.
The equipment rack has an identical redundant computer drawer as a ready spare, complete with a seperate hard disk and all. One hard drive came pre-loaded from the manufacturer and the other was loaded with the same software by the client from media provided by the manufacturer. I've swapped hard drives with no change and the client has reported swapping the entire computer with the ready spare with the same result.
The problem reportedly only surfaced a few weeks ago, but of course they can't think of anything that "happened" a few weeks ago. This is all new equipment less than a year old, but it may have been sitting in a warehouse for a few years before being installed.
Programming :: Closing Multiple Client Sockets In Server ?
Nov 30, 2010I have written a server application which has select for both incoming new client connection requests and incoming data from client. I am able to process incoming connection requests and client data.
For example, server has 8 clients connected to it. If client 3 disconnects from server, how will server come to know this client has disconnected and to close its client socket fd gracefully? Does server's select get data on that client socket fd as 'close' data or any error code in recv() function that notifies server to close this client socket fd? Also if client disconnects abruptly without sending close request to server, how should server handle this? Does server get "EPIPE" error?

Server :: Redirect Local DNS Query To Remote DNS Server On Non Standard Port?
Feb 19, 2010The issue is that my CentOS workstation is in a vlan from where the Intranet's DNS servers are unreachable. For browsing the web there is an ISA proxy server, which I presume resolves DNS for my firefox. However, wget, host, ping and aria2c fail to get any sort of DNS resolution since they're being run from command line.I have exported HTTP_PROXY value, which provides me internet access on console, but,only when I connect using IP address. It fails on name resolution.
My question is:May I redirect the DNS queries to my home PC which would be running a DNS server on a non standard port?I was thinking of putting nameserver 127.0.0.1 in /etc/resolv.conf and then put iptables rule to redirect 127.0.0.1:53 UDP to a.public.ip.address:3535 UDP..I don't know if I am shooting blanks or what, I am not very much aware of this kind of setup.My main need is to provide DNS resolution to console apps.I want to utilize my company's idle bandwidth for bulk downloads, so, using proxy, SSH tunneling through my Home PC is out of question.
Server :: Setup Reverse Proxy With Proxy_mod To Port 443 On IIS Server
Aug 30, 2010We currently have a SUSE Apache2 reverse proxy server setup to reverse proxy (proxy_mod) our GroupWise Web Access server. Our SUSE box is located at www.domain.com. Our GroupWise Web Access server is located internally and is called GWMail. We are in the process of migrating from Novell to Windows, so we will have an exchange server with OWA access running on a Windows Server 2008 IIS7 box. That one will be called EXMail internally. Right now when someone goes to www.domain.com/gw/webacc it goes to the GWMail internal server from the outside world. This was all set up by previous techs who used Linux more.
We would like to set up reverse proxy to be able to reverse proxy to the Exchange Server from the outside world. Unfortunately the snag we are running into is that Exchange needs to run on port 443, and forwarding to port 443 has been a little tricky. I've read elsewhere we need to implement a generic TCP proxy, such as IPtables. what we need to do to get our SUSU Apache2 server to be able to reverse proxy to our Exchange server on port 443. For the save of argument lets call our SUSE server ExtranetServer. Below is our default-configuration.conf file's configuration:

Networking :: Port Forwarding 80 To LAN (Web Server)
Feb 3, 2010I have two PC's, one with slackware and one with arch, and I am trying to access the web server from the archlinux machine but i haven't manage to do that. The archlinux machine is connect to the internet via the slackware machine via a crossover cable:
internet > eth0 (pc1) and ppp0 (the PPPoE connection, pc1) > eth1 (pc1) > eth0 (pc2)
PC1:
ifconfig eth1 192.168.0.1 netmask 255.255.255.0
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
iptables -A FORWARD -i ppp0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i eth1 -o ppp0 -j ACCEPT
pc2:
ifconfig eth0 192.168.0.2 netmask 255.255.255.0
ifconfig eth0 up
route add default gw 192.168.0.1 eth0
/etc/resolv.conf (The same DNS as the first PC)
And now the internet is working and on the archlinux machine, but I am not able to access the web server from LAN with a public IP. I tried many iptables port forwarding commands but none worked.
