I've juste been scanned for a port assigned to "tcpmux", whatever that is,
and ports 1 through 6... Firewall blocked it, but I find it rather strange.
Someone knows what these ports are used for ?

TCPMUX never received wide use, but some versions of inetd include built-in
support for it.

Thank you. It was certainly a mis-configured process... I doubt anybodyQuote:>TCPMUX was intended to be an alternative to assigning port numbers to

Thanks again !
Ooops... reading logs at 1 pm isn't a good thing to do ;)Quote:>Tcpmux *is* port 1.
as a way to scan for irix >machinesQuote:>Since few inetds do tcpmux but irix inetd does, this has been widely used
Reminds me of something about "bugs" and "features" ;)Quote:>"fostering collaboration"
Thank you for your comments.
More directly, scanning for tcpmux has caused some SGI's inetd to die.

I am porting an application that uses tcpmux from Irix to HP-UX 10.20.
Is tcpmux available on HP-UX? If not, what is involved in porting it?
More generally - how widely implemented is tcpmux? Does anybody know if
it is on other unices, and if so, which ones?
I am also interested in the pro, cons and alternatives to tcpmux. All I
have really found so far is RFC 1078.
Thanks for any help.
