I'm not getting any errors and the file is being created client side however it always seems to fall short of the total file size. I have tried many different options in regards to input streams and buffer sizes but I have had no luck.

We have connected two systems with ethernet cables and have configured the two systems with ipv6 addresses. The IP of one system is 2001:0db8:0:f101::1 (let's say X::1) (This system runs OS Fedora 10) and the other is 2001:0db8:0:f101::2. (Let's say X::2) (This system runs OpenSuSE 10.3) We are able to ping from both systems to the other. We are able to ssh into the one with IP X::2 from the one with IP X::1, but not vice versa.
We have disabled iptables on both systems by using the following commands: /etc/init.d/iptables save /etc/init.d/iptables stop on the fedora 10 system and # iptables -X # iptables -t nat -F # iptables -t nat -X # iptables -t mangle -F # iptables -t mangle -X # iptables -P INPUT ACCEPT # iptables -P FORWARD ACCEPT # iptables -P OUTPUT ACCEPT on the openSuse system.
The error we get in trying to ssh from the openSuse system to the fedora system is: ssh: connect to host 2001:0db8:0:f101::1 port 22: Connection refused
We're trying to write server and client code to send data from one system to the other using SOCK_DGRAM. The code works fine when we run both the client and server on the same system. However, we are not able to send data from one system to another when we use the IPv6 addresses to run the client and server programs.
The error we get is: sendto(): Operation not permitted
The codes we are using for the server and client programs can be found here in beej's guide here : [URL]. We've only substituted the appropriate addresses in the right places... We've disabled the iptables...
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)?
One of our postfix servers is for sending/receiving internal emails only. When a user entered a wrong recipient address, it will take almost an hour for the user to get the "Recipient address rejected" email. What can be done to let the user get the "Recipient address rejected" email quickier.
We use mutt to send out emails.mutt -s "Test" -e "Content-Type: text/html" firstname.lastname@example.org < message.htmlWe send out our email updates in HTML format. We would like to send emails as multi-part containing both a text version and an html version. How do we create such a multipart message in Linux when the email subject, and HTML and text versions of the email body are given?Can we use mutt to send the multipart email created in step 1, from the linux prompt?
here is a fragment of a bash that i have to send an email when a back Up is made. basically a usr runs the sh - it asks for the job num and I read that from standard in . I do a tar of the drv to tape and I wish to send an email that job such and such has happened. My problem is : the subject of the email. I can set it - but if i try to use a var ( as in the $jobNum ) that Does work in the mail body - the subject comes out blank. I have also tried to buld a text file and shove that in the SUBJECT. my Q is how can I use a var in the subject.
# email subject ### so I have tried bulding and reading a tmp file -no works EMAILSUBJECT="/tmp/emailsubject.txt" echo "backup job" $jobNum >$EMAILSUBJECT
I cannot send an email link in Namoroka. I go to file-send link and nothing happens. I tried to find the problem by about:config in Namoroka. I just found /usr/bin/mozilla-thunderbird. With my limited knowledge I do not know what else to look for.
I have sendmail setup and it works fine sending emails to outside email addresses. When I try and send email to our internal groupwise server the mail never gets there and I get an error message in the log user unknown.
I have a desklet that, occasionally after toying with network stuff, will tell me that large amounts of data are being sent/received. What's a good way to determine what processes are occupying these resources?!
I have a server which is used by number of client Apps. Now when a client initiates a sendto request to a server it has to respond(after recvfrom) by sending a message using sendto back to client and this should be done back and forth.
What I dont understand is, does the client have to open a new port to receive packets from client? If yes, then how will server know to what port of the client(assuming server ports are well-known to clients)?
I had given up on sending messages back and forth using UDP and switched to TCP. I could send a read and write message back and forth. But the trouble comes when I have more than one client wanting to talk to server using SOCK_STREAM. The first one gets through but the second client seems to get blocked forever(but I got no error upon socket creation or upon connect with the server on the same port as the previous client)..
I am looking for free and well known fax command line tools for receiving and sending faxes I wan it to save receive faxes in pdf format with file name included with caller phone number and date of receive:

I come from more of a programming background but have been giving the task of sending backup results from a linux box in an email to external email addresses, I have spent days looking trough google for info but cant seem to find anything simple, I have looked at postfix but because I don't understand networks, hosts, nameservers etc. What I need to do to allow mail get sent from the linux box to external mail address. I have outlook connected to an exchange server on windows and I can ping the linux box from my windows command so surely it cant be to much involved.
I checked task manager the other day and I discovered that on the network history monitor some bits and bites were transfered in a repeating pattern (like a beacon). The transfer rate (when active) is about 149b/s receiving. And about 70b/s sending. What is this?
No Internet-related program was running from my part...In an attempt to pinpoint what was causing this, I occidentally removed the tools located left and right on the time and date. I've rebooted since but still no tools. The 0/I button is also gone.
