sendto

I am experiencing some unexplained behavior with an app that is writing UDP data with sendto() to multiple ports (all opened with socket(PF_INET, SOCK_DGRAM, 0) ) for the benefit of a set of client reading processes. These sendto()s occasionally and unpredictably trigger ECONNREFUSED errors. This is happening on a macOS Sierra (10.12) system whose sendto(2) manual page does not even list ECONNREFUSED as a possible error. Interestingly, I have a CentOS7 system (where these errors never occur) whose sendto(2) manual page references additional sendto() errors documented on the udp(7) manual page,

7z a -mx9 -sfx %1.exe %1 This is what i have so far as a batch file, which if i drag and drop a file or folder onto the batch file i get a 7zip SFX on Ultra Compression under the same name as the original file. but this only works if the file is in the same folder as the batch file. What im trying to achieve is, putting this batch file into the sendto folder so i can convert any file anywhere into a highly compressed exe, which appear in the folder of the original directory. Any help would be greatly appreciated, im sure its simple but i haven't a clue. Edit 29 May @ 16:50 [HKEY_CLASSES_ROOT*

I'm going to start of by noting that I have next to no python experience. alt text http://www.aquate.us/u/9986423875612301299.jpg As you may know, by simply dropping a shortcut in the Send To folder on your Windows PC, you can allow a program to take a file as an argument. How would I write a python program that takes this file as an argument? And, as a bonus if anyone gets a chance -- How would I integrate that with a urllib2 to POST the file to a PHP script on my server? Thanks in advance. Edit-- also, how do I make something show up in the Sendto menu? I was under the impression that you

This is a slightly obscure question, but I'm stumped and I thought maybe somebody out there might have more of a clue on the issue. My co-worker has been successfully running an in-house application that uses IPv6 multicasting on his MacBook Pro for several months, but today the Mac decided to stop routing the multicast packets. In particular, the program prints this error: SendDataUDP(ff02::bead:cede:deed:feed@4) failed on Network interface [Name=[en0] Description=[] IP=[fe80::222:41ff:fe21:dfd4@4] Netmask=[ffff:ffff:ffff:ffff::] Broadcast=[::]] (errno=65/No route to host). ... which pretty

I am using C language which is a common platform for both the server and the client. I have a structure of a particular type which I want to send to the client from the server. For e.g. SERVER CODE //necessary declarations struct hostent *hp; hp=gethostbyname("www.google.com"); sendto(sockDes,&hp,sizeof(hp),0,(struct sockaddr *)&cli_addr,sizeof(cli_addr)); CLIENT CODE struct hostent *hp; msg=recvfrom(mysock,&hp,sizeof(hp),0,(struct sockaddr)&serv_addr,&size_len); So , basically I want to send a structure from the server to the client. But from the above pieces of code I am getting segmentation

Server should, based on the client input calculate client's network byte order, and send it back to client. I've been trying to fix this error for whole day now. Any help would be apprecciated. Here is the server start and output: ./udpserver.out 4545 from.sin_family: 12079 Little Endian ERROR UDP_SRV_004 - can not send message to client: Address family not supported by protocol Client start: ./udpclient.out localhost 4545 Server code: #include <stdio.h> #include <sys/types.h> #include

At first you're going to think "Wait, this question is a duplicate!". Read on. I'm trying to use the Intent ACTION_SENDTO (with an Email URI as data) in order to have just email apps respond. (Using ACTION_SEND launches a standard "SEND" chooser with no data URI meaning that non email apps, such as Google Drive, also respond). My problem is that the attachment works with ACTION_SEND on all devices, however - when using ACTION_SENDTO only some devices correctly attach the files. Nexus 7 works but Samsung Galaxy Tab and Acer Iconia don't . You can see below the different methods side by side:
