Hi all,
Yesterday i sent this message to the list.
Sometime (not everytime that's what make me crazy) it seems that pppd does
not recognize that clients close the connection.
Infact if i make a ps ax| grep ttyD i can see pppd process running even if
nobody is dialing in. Killing the process everything restart to function
well for a period and then it appens again.
I added the debug and kdebug options in the options file and i discovered
that pppd sometime (I repeat, not everytime that's what make me crazy)
doesn't recive [LCP TermReq] even if the connection is closed and the modem
is hanged up (i can say this because the OH led on the modem is off).
I added the
lcp-echo-interval 15
and the
lcp-echo-failure 2
in the options file, so, even if pppd doesn't recive [LCP TermReq], after 2
[LCP EchoReq] without any [LCP EchoRep] pppd close itself.
Things seem to work, but now I gess
1) why this appens?
2) Is this the right solution or simply I'm going round the problem?
3) Sending an [LCP EchoReq] every 15 secs how much overhead i add to the
trasmissim?
4) Is it possible that a client doesn't send an [LCP EchoRep] after 2 [LCP
EchoReq] even if the connection is up?
Help, suggestions or comments are very very welcome.
Thank in advance.
Best Regards
Accursio.
