Good day list!
I've found out the real problem...(when a client on my lan tries to
connect, the first
connection try is dropped, and the user has to retry)
taken from : http://www.redhat.com/mirrors/LDP/HOWTO/mini/IP-Masquerade-4.html
4.6 IP Masquerade and Demand-Dial-Up
(...)
4.Diald will detect the incoming request, then dial up your ISP and
establish the connection.
5.There is a timeout that will occur with the first connection. This is
inevitable if you are using analog modems. The time taken to establish the
modem link and the PPP connections will cause your client program to timeout.
This can be avoided if you are using an ISDN connection. All you need to do
is to terminate the current process
on the client and restart it.
Second, if after lengthening nameserver timeouts you are still having
problems,
then you probably want increase the timeout for starting new TCP
connections. This can be done by
increasing the value of TCP_SYN_RETRIES in net/inet/tcp.h, and recompiling
the kernel.
Note that increasing this value by one will double the timeout.
Ok, I said, this is the problem...so I've tried to change the kernel
parameters, but had no luck!!!
I'm using RH 6.0, kernel 2.2.5.....is it so different from the version to
which that doc refers ?
or perhaps should I lengthen some parameter on the bind options ?
did anyone had my same problem ? possible ? everybody has at least an ISDN
connection on the lan ?
what should I really change in the kernel headers ?
Best Regards!!
