PPPOE and web

[eaglematt]

hello
i have a "little" problem,
i use a ericsson modem for my adsl connection
the system connect fine but is slow to initialize ppp0 device
the problem is : ping, ftp work fine but http,smtp,pop3 don't work
i have disabled any firewall

have you an idea???
in win32 with enternet software is all ok

thanks for all

does ping resolve hostnames correctly? if websites just don't seem to reply, you might be using a bad MTU value for your connection.

also
ping resolv correctly the url
and any browser send correctly the query (i monitor this with ethereal)
with ftp I have downloaded files
if I'd have bad mtu and mru,
I could retrieve the current mtu/mru from win??
Maybe, do you now how??

thanks for all
Matt

the windows mtu is not that important... just use a smaller value, you should think about the optimal value only if that fixes the problem.

ok
I found a mtu for win32 with sys info but for tcp is 0 and for udp is 64k

in the aftermoon I test the probvlem with various mtu
thanks for all

I have partially solved
I set MTU to 1452 and all works (I continue to testing sys)
but the setting in net.ppp0 don't be in ifconfig output when the connection start
only with manual setting works
when I solve this,I set SOLVED this thread
thanks thanks

Depending on what you use to create the ppp connection, you might be able to set the mtu in the PPP dialin config script, or there is a interface-up/interface-down event (if.up script) where you can put those settings. I'm not using PPP directly anymore, so I don't remember exactly.
