i am new in tcp/ip.i want to write a program using c for file transfer where FTP client and FTP server will be used.and also this program should work for ipv4 as well as ipv6.and muiltple client can be connect simultaneously.i dont know how to start program.should i use shell script or socket programming for file transfer?can we use FTP client and FTP server in socket programming?
View 2 RepliesI need help to do a program that emulates the following shell command line:"sort </etc/passwd | less".Using a socket in a connection-oriented setup.First the contents of the file /etc/password are being fed into the sort program. The sort program is then sorting the contents of the file and sending it to another programm called less. Less is paging the results so that you can see one page of the results at a time.I know that i can solve the problem this way:
1. Create a server program that will stream the contents of a file to any client that connects to it
2. Create a client application that will connect to the server and download the contents of the file. The program should then sort the file. After sorting the file the client should connect to the "less" program and send the sorted results
3. Create a server program that will listen for connections and download whatever is sent to it. It will then display that data one page at a time.

I am trying to write a chat program with sockets as part of my project. I made a socket server, using fork ,I tried to connect it with different clients.Each client will send messages to others through server.So server has a shared memory storing every clients username and client id. But the problem facing is first client is able to sent messages to every other client formed after that.But second client onwards it is not able to sent message to previously connected ones. Server is not able to write on those client id's.
View 4 Replies View RelatedWhen accessing an NFS mount for a large (200MB+) file transfer, the transfer starts rapidly, then becomes slower and slower until it hangs. On several occasions, it has frozen the client machine. Both client and server are set to default to nfs version 3. Slowdown and hang also occur when connecting to FreeBSD NFS mounts.
Presumably (I hope), there is some sort of configuration for the client that needs to be set. what should be changed in the configuration? This worked out of the box in OpenSUSE 11.0.

View 7 Replies View RelatedI'm carrying out a project for my university (CIT in Cork, Ireland) and I'm using CentOS running over WMware. I have a server and a client. The server has no GUI (command line UI) while the client has a UI. I need to install a Simple Forum Machine application and I'm told to FTP the files into the server. I figured out that the best option is to load the files in the client via the GUI and then ftp them in the server. How do I transfer the files from a the client t o the server using FTP? I'm totally new to Linux so the more details the better. Also I'm trying to mount a USB key on the server but have had no luck.

Having a bit of a issue with Debian Squeeze and transferring files to the Sony PSP..Hook up PSP to USB port and Debian mounts it..I go to drag a 125 meg mp4 to video folder..Copy windows takes about 10 seconds to transfer it..Exit USB mode and there is no video there. Go back into USB mode and look at video folder on the PSP memory stick and there is no video..It vanished. From another after copy progress closed I right clicked PSP and unmounted it..
It error-ed saying device was busy and could not unmount..Looking at light on PSP i see memory stick is still being written to..i wait for light to stop flashing..About a minute or so..Then am able to unmount it..Go to PSP video and theres the video ready to be watched. Debian isnt accurately showing the copy progress...Its showing complete when it isnt..I have to watch the light on PSP to know when it is truly finished.

View 1 Replies View RelatedIs there a way I can install a windows program to webspace and run it from a linux client computer? To specify, I'm a student at the University of Minnesota. I have access to linux machines running Ubuntu, however, the space allocated to us is too small for the program I would like to run on these computers. I do have webspace I can use though. The thing I'd like to be running on the linux computers is a windows application requiring installation. So is there a way to put/install/(whatever else it might be called) this program onto my webspace and be able to run it from the linux computers? I know it's probably unlikely, but maybe?

View 2 Replies View Relatedsetting up a basic apache webpage that would allow users to view files and folders on a server and transfer it from one directory to another? I know it doesn't sound very secure but this is an internal server so security is not a big issue as it is pretty secured in its network already. We have users that need to move files from one directory to another and we'd like to give them some intuitive interface to do this rather than having them log in to the linux system and run mv/cp commands. They are not very linux saavy.
PS: The system is running CENTOS 5.4.
I'm trying to transfer a large .tgz file from a CentOS dedicated server to a linux webhost (unknown OS). The problem is the webhost will not allow a 1.1gb file to be uploaded, however it will allow the upload in 149MB chunks. I used the split command to segment my tgz into 7 segments under 150mb. I then uploaded all segments via FTP which worked. Then I tried to join the segments to create the original tgz. The join appears to work with no issues. However, when I try to extract the tgz it appears there is a problem, most, but not all files are extracted and there is this error message:
Code: gzip: stdin: Input/output error
tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now It appears the join did not work and the tgz is slightly corrupt. What am I doing wrong? Here's the commands I'm using:
1. Create the original tgz on the dedicated server
Code: tar -czf mysite.tgz ./myfolder
2. Split the tgz into segments
Code: split -b 149m -d mysite.tgz seg
# using the -d switch so the segment files use a numerical suffix
# I now have these files:
seg00
seg01
seg02
seg03
seg04
seg05
seg06
seg07
3. Transfer segments to the other webhost using FTP
Code: # hand typing (not a script)
ftp ftp.mysite.com
myusername
mypassword
binary
cd somefolder
put seg00
put seg01
put seg02
# through to seg07
4. Join up the segments on the new webhost
Code: # this is in a .sh script file
cd /full/path/to/somefolder
cat seg* > mysite.tgz 5. Extract the new tgz
Code: # this is in a .sh script file
cd /full/path/to/somefolder
tar -xzf mysite.tgz
# the above error is now thrown.
That's it. What am I doing wrong that's causing the above error?
if connecting to my server for file transfer using gFtp is secure. I told gFtp to connect to the server using SSH2 and it works. It says it uses this command "ssh -e none -l wordpress -p 1883 IPADDRESS -s sftp." Is this more or less secure then using ftpes or ftps? What I thought was weird was that I could shutdown vsftpd and still connect. Does SSH2 SFTP use its own ftp server?

Network is fine, samba share to the media direction works, until I try to upload a large file to it from my desktop system. Then it downloads a couple of percents at a really nice speed, but then it stalls and the box becomes unpingable (Destination Host Unreachable), even after canceling the transfer, requiring a restart of the network.
Same thing when I scp the file from my desktop system to the htpc, same thing when I ssh into the htpc, and scp the file from there. Occasionally (rarely) the file does pass through, but most of the time the problem repeats itself. Transfer of small text files causes no problems, and the same goes for the fanart downloads done by xbmc. I tried the solution proposed in this thread, and set mtu to 800 in the interfaces file, but the problem persists.

View 2 Replies View RelatedI am transferring a file from a linux pc going to a windows ftp server using "ftp put". My file is a zip file that includes .txt files inside it. Here is what's happening when I transferred this file :I used ftp put for transferring and found that my transferred zip file was corrupted and couldn't be opened on the ftp server.I found the solution for this on the internet. I needed to use 'binary' to make it right.
I transferred again using binary and then ftp put the zip file onto the other end. Yes, it worked. My zip file wasn't corrupted anymore and I could already opened it on the ftp server. But the problem remains on the .txt files inside it. Converting the file into binary made my .txt files to be distorted and unreadable. I read from the internet that .txt files need to use Ascii instead of Binary to be readable, but if I use ascii it would cause my zip file to be corrupted again. I need to successfully transfer a zip file that contains .txt files using ftp put.
