I'd like to open this to discuss server administration, server setup, and server maintenance. However, I have a pretty good start on all of those but serving a domain name to my static ip. Here my static ip is 24.10.202.144. I registered a domain through [URL]... It appears that I have the domain working to forward to my ip. However, I am still getting this output file from apache.

I have tested the domain name across a few different computers on different ips. It works appropriately. I just want to make sure I have it set correctly on the (apache) server side of things. Then I can get more into Zone Editing etc.
I am doing a project where 2 clients connect to server and communicate (chat) and transfer data one after other using sockets. I have working code for this in C language. Now our main aim is to create a communication link where two clients transfer multiple streams data parallely. To be more precise i want to transfer images files and audio files parallel at same time, so is it possible to send data parallel using one socket connection?

This new QSocket is passed to the connect () function which connects it to a SLOT 'xyz' with SIGNAL 'readyRead()'. Now in the SLOT 'xyz' how I am supposed to automate the monitoring of ALL connected sockets to see whether some data is available on them? One pathetic way would be to run all the sockets through a for loop and check each one of them for the data. Secondly, I read up on QSocketNotifier() here: [URL]. But I am not sure if that is the correct thing.

char info [256];
bzero(info, 256);
//memset(&info,0,sizeof(info));
read(socket, info, 255);
write(socket, HTTP, 255);
FILE *fl= fopen(info,"rb");

printf("largo: %ld", len);
unsigned char *ret = (char*) malloc(len);
fseek(fl, 0, SEEK_SET);
fread(ret, 1, len, fl);
However, it's supposed to be shown in Mozilla Firefox (as the client). But it is not doing it, so.. It's just not getting the complete file.
I would like to send a data using one thread and receive a data using other thread by using a same socket connection using USD sockets. The calls i am using for sending and receiving are send(), recv(). let me know is it possible to send and receive the data parallel (Full duplex communication)?
View 2 Replies View RelatedI 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?
Faced with disk-bound issues on a FTP server with high traffic. Would like to set up multiple FTP server nodes with dedicated storage for each node where all FTP access is managed by a master FTP server. So, a user would FTP to a single externally visible IP address for the master FTP server and then get routed to the appropriate FTP node. Are the mutiple FTP nodes required or is there a better way of doing this? Perhaps only one FTP server is required and then each node would serve as a separate file server

We purchased a new database system at work last October, ditching the old system because of a lack of support from the vendor. This is a retail Point of Sale and Backoffice database system. I am not sure what system the new one runs on, but the system we replaced was a Firebird data base. The reason I am posting is because we are now in need of the information contained in the old database which was not completely imported into the new system.
Basically the problem is this: The database in on a Windows XP system and I found a copy of SQL Manager Lite 2008 on the system, which after quite a bit of studying, I figured out how to extract the database into a removable file. I have this file (178MB) on a USB stick in a file called Backoffice.fbd.
My studying suggests to me that I can get into this database with MySQL. I have never used this and have no clue how to do this. All I want to be able to do get into the database and create tab deliminated spreadsheet files for each of the database sections (Customers, Repairs, Sales History, stock files, etc.) Is it possible to do this with Ubuntu and MySQL and if so, can expert suggest one or two things to get me started. While a guided tutorial would be nice because I am not an expert, I am willing to learn on my own if someone could point me in the right direction.
Where apart from ~/.kde4/share/apps/kmail does kmail keep account data, such as login data/names of pop/smtp servers? I wanted to install an entirely clean version of kmail, so I uninstalled/re-installed kmail via YAST. I manually deleted ~/.kde4/share/apps/kmail. After installing kmail I found that the account data of my Yahoo account were still listed in the kmail configuration panel. Shall I delete the Yahoo account within kmail prior to uninstalling the kmail package?
View 4 Replies View RelatedI am trying to setup a web-based secure ftp client that can handle not only file transfers to and from one of my company's servers, but also allow new clients of ours to visit our site, create an account of their own and use it to log in and begin transferring files. This way, the users can manage their own accounts.
I don't know a lot about exactly what is running on our server, though I am almost positive it is debian based. I really only have access via ssh and ftp. I may be able to do more in the server room, but haven't tried. I thought about using net2ftp, but that doesn't seem to work with sftp, and also doesn't allow the creation of new users on the server.
Is there anything out there for me??You will undoubtedly require more information from me, so please let me know what it is and where I can find it and I'll get back to you as quickly as I can.
I should preface this by saying I'm pretty much new to ubuntu. I was a nerd back when I used windows, so I'm fairly knowledgeable about it, but I lost interest right before switching to linux, so I haven't learned much past basic navigation.
I bought a WPN311 wireless card for my homebuilt machine a while back and still can't seem to get it to work.

I have very little linux experience. And need some help with a bash script. I need to a script I can set cron to run to sort files out of a holding folder into final folders. It doesn't necessarily have to be bash, but I think it would be sufficient for this. File names are formatted as such when created: Dest-Date-Time-CID-Destination# I want the files to be moved from a all in one holding folder to a folder structure like this.
.../storage/year/month/day/Destination#/VarX(type)/hour/CID/'File'
I would need an if/else if/else statement to say if Dest = A set VarX = B If for example the file name was
infinity-20100927-17:00-1112223333-4445556666.wav
I would like the above file to end up moved from
.../holding
to
.../storage/2010/09/27/4445556666/Inbound/17/1112223333/infinity-20100927-17:00-1112223333-4445556666.wav
So the script will need to make directories based on information in the file name which is delimited by single dashes. Then move files from the holding folder to the newly created "sorted" folders.
I ended up setting up a basic linux file server as a pdc for that office. Our main office is a windows 2000 ads domain. The two offices are connected with a vpn. I only have two users at the new location so I simply have the linux and samba usernames/passwords setup manually. I would like to know if it is possible to setup a domain trust between the two sites so I don't have to create a username/password in the remote site for every user at the main office to access. I did some searching but came up empty.

View 1 Replies View RelatedI am moving some websites from a shared host to a newly configured Xen based VPS with Ubuntu 10.04. A steep learning curve but I am getting there! I have a couple of sites installed on the new server and want to test them out, from what I understand I should be able to edit /etc/hosts on my desktop computer (running Ubuntu 10.04) which should automatically redirect my browser to the new server. But it doesn't seem to work.
This is what I appended to the /etc/hosts file:
12.34.56.78 www.xxxx.com
I thought that this should send any requests for www.xxxx.com to 12.34.56.78? Some googling indicated that the browsers I am using may be using DNS caching, ignoring the hosts file. I've tried clearing the cache with Chromium 7.0.517.44 (64615) and Firefox 3.6.12, and even installed a plugin in Firefox to block DNS caching.
how do I tell grub to stop trying to boot based on UUIDs? I've been dealing with this for about two years now. I have this one system, a PowerEdge 1550, that for some reason WILL NOT boot using a UUID, and will only boot if I edit the first entry in grub, remove everything to do with UUIDs (completely delete the search line, replace root=uuid=[uuid] with root=/dev/sda1). I can't seem to make these settings stick and now with 10.10 there's no longer a menu.lst to edit. So, in short, I need grub to stop trying to boot based on a UUID. Absolute paths, baby. That's what I need.
