I got an error Unable to Connect to Host :lynx.org and the program terminated . This is inspite of the fact that my internet connection was fine and dandy I spent a weekend tracing the bug and luckily found it. Therefore this mail for all those facing the same problem and for the maintainers of the package to hopefully fix it in the standard distribution. (specifically Corinna Vinschen of cygwin) (i was told that u are maintaining it in cygwin). Following is a piece of the log file generated from lynx -tlog -trace (the whole file was too long and irrelevant to post here) (I also had to edit this portion a little bit because it had control characters and my email editor got confused) start_curses: done.

Following is the piece of HTTCP.c file that i changed. 1594 1595 #ifdef _WINDOWS_NSL 1596 timeout.tv_sec = 100; 1597 #else 1598 timeout.tv_sec = 0; 1599 #endif /* _WINDOWS_NSL */ /* line 1600 below read like: timeout.tv_usec = 100000; before I fixed it. I just increased the timeout value from 100000 micro second to 900000 microsecond */ 1600 timeout.tv_usec = 900000; 1601 FD_ZERO(&writefds); 1602 FD_SET((unsigned) *s, &writefds); Hope this helps Let me know if somebody wants me to send a diff patch also send me the instructions on how to create it I am too lazy to find it out and dont exactly remember it Feel free to write to me with any questions.
