I have just installed Ubuntu 10.04 and it works fine. Next, I attempted to install Apache 2.2.16 server on the machine. I was able to get Apache installed but I cant't get it to start. The command I used to get it to start is "apachectl -k start" and got the response "command not found". Then I used the absolute path which is "/home/Administrator/Downloads/apache/bin/apachectl -k start" and got the response"httpd: could not reliably determine ther server's fully qualified domain name, using 127.0.1.1 for ServerName(13)Permission denied: make_sock: could not bind to address 0.0.0.0:80.no listening to sockets available, shutting down". Please advise me on what to do. My eyes hurt from looking at the screen for so long trying different options and reading almost all the apache install instructions that exists. Just ready to have it up and running.

I am very new (since yesterday) to Linux also new to web server setup. I have installed all LAMP components, including SSL as described here: [URL]. I have added LISTEN 443 Wanted to restart the apache server -> no success ! stopped it, now doesn't start at all:
Warning msg=>
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:44 no listening sockets available, shutting down . .
Failed
I tested Apache and my PHP earlier and it worked. Now after SSL and FTP installation it doesn't work anymore! Also I am wondering about my server name, it is the set IP of the web server, surly i should change that? Only used link for SSL set-up, used diff links for apache php etc (also have java JRE installed as I will need that later for my app) also have GNOME available, but prefer command line.

I was logged in as root, made some changes to my users and think I may have inadvertently changed root somehow. Ever since then, my machine runs just fine, I can sudo, Yast, etc without any issues. (Root password is fine) but when I try to log in as root, the system changes the screen display, as if it's going to login, then returns me back to the login prompt without error. If I "ctl+alt+F1", I drop out to the console and can login as root, but cannot startx because the display is already in use.... So, I removed the .X0-lock, but still cannot get the GUI to load. (after running rm /tmp/./X0-lock, I get a fatal error, "can't establish any listening sockets..." "Ctl+Alt+F7" brings me back to the GUI where I am logged in as myself in Gnome) if I login with my user account, everything runs fine and all is well.

I am trying to get SQL-Ledger installed and running on my computer, which needs PostgreSQL installed to run.Currently, I am having trouble with it starting at boot-up. How can I access the appropriate log files in order to figure out what's wrong?
Also, I need to know what httpd is, and who the owner and groups using that might be on my system.

The problem started when I noticed I couldn't upload to people using a torrent downloading program, the program listened on port X and when I sniffed on the same port I saw that syn's are forwarded correctly from my nat to that port but the program doesn't relate to those packets. Then I listened with NC, and even on another port nothing is being answered to those syns packets.

I run various manual checks on my system to see if there's anything I can't account for and just one such instance just got thrown up here. I reproduce the output from netstat below. I see there is something called "microsoft-ds" shown as listening. What on earth is this doing on my PCLinuxOS box? I have googled it and there does appear to be some security issues related to it for Windows users and all the advice relating to it that I could find is for Windows users, but I am just baffled as to what this is doing on my Linux system.

I have a C program which does.
1. Creates a UDP socket
2. Send the UDP Request packet to the TFTP server.
3. If the TFTP server is not listening in the 69 port, the remote machine send an ICMP ("Port Unreachable") message.
Is there a way to receive a notification from the Linux kernel on receipt of an ICMP packet to the created UDP socket.

In emule p2p filesharing there's this thing called the id that is low if you do not configure your router for certain ports to be listening for incoming connections, forwarded by the router to ports on your pc. When the id is low, your downloads take longer or something like that. But if you have no listening port, how can a peer download from you?

I wrote an application that receives packets on one interface and sends them to another interface after it added a vlan header. Both the sending and the receiving is done using raw sockets. Everything seems to work fine until I get TCP packets that are of size 1514 (MTU). Once I add a vlan header to the packet, its size becomes 1518 and when I try to send it I get the returned value -1 and errno=90 (message too long). I tried to change the MTU of the NIC to a value that is bigger than 1500 but that fails. If I create a bridge using brctl and vconfig between the NICs I can see that my NIC does sends packets of size 1518. What do I need to in order to make my NIC to send packets of size 1518?

I am writing a code in Python where a socket client changes data with the server. That works nice if the connection is up. However it is also supposed to work offline. So I need to be able to detect if the connection is up before sending data, but I was not able to do so. A summary of the code is like that:
Code:
try:
socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socket.connect( (self.host, self.port) )
connected = True
except:
connected = False
if connected:
data = "some data byte"
try:
socket.send(data)
except:
connected=False
socket.close()
If I unplug the cable after the connection is ready then the socket sends data and does not detect the connection failure. What is amazing is that the client detects the connection failure just after the cable has been plugged again. Of course there is a loop in the code above and always that connected==False a new connection is made. How could the program detect the connection failure before sending data and then lead the code to an exception?

During the development of a java application appearantly found that cannot bind more than 500 UDP sockets at the same time.
The developed java application is running on Fedora Core (x64)
Is there some procedure to check how many sockets I can bind at the same time on that linux distribution?
In case the limit exists, can it be increased easily?
$ uname -a result is :

I am learning about net filters and I am practicing some sample programs on it. I am very new to this and I have a general query. I got the packet to a desired function using PRE_ROUTING hook. Now how do I frame a packet from this point? I am just trying to simulate a echo client server program in the kernel level using these hooks. Any useful info on sockets in the kernel level?

Looking for a test tool where I can fire up any number of ports (TCP and / or UDP) to listen on.
I am currently getting my using nc but its only 1 port at a time (i know I can open up multiple sessions but thats cumbersome), it can't do UDP, and it closes at the end of the session.
A friend has suggested socat but it looks pretty much the same except it can do UDP, but also cumbersome, I have to manually output to a different file per port, etc.
Basically its so I can quickly test firewall and NAT rules.

We are using this url on our testing box and this ip is reverse proxy IP ( 10.192.64.52)
Without reverse proxy:- URL is working fine.
http://10.192.16.77/akc-qa/arsys/ser...TS000000001430
But with reverse proxy its putting escape [%25] in between %3a
[url]
Is it possible to write a rewrite rule to bypass escape [NE] for this particular URL?
