i'm not sure which info page you're looking at, but as far as i know, 'shutdown' will not discar data currently found in the socket's buffer. it'll emit the EOF only after it send all pending data. on redhat 7.3, as well as on fedora core 2, the man pages state nothing about such data throwing. you can also look at the source code of apache (for example) to see how they use shutdown (on some platforms...). -- guy "For world domination - press 1, or dial 0, and please hold, for the creator." -- nob o. dy ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
