I tried the command George Bonser suggested: echo 0 >/proc/sys/net/ipv4/tcp_timestamps but that had no effect.
He also suggested turning off all ppp header compression, but I could not find where that is specified. Does the /etc/ppp/options file get read before each dialup, or only once for each login? I tried some editing of the file, but nothing I did made any difference. Here is a copy of the options file without any comments: asyncmap 0 auth crtscts lock modem mru 542 proxyarp lcp-echo-interval 30 lcp-echo-failure 4 noipx Are any of the other files in /etc/ppp important? Keith Murphy mentioned modem init strings. Kppp in Corel Linux uses only ATZ, but I see that wvdial, which I'm using in Debian, has the following strings: Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 S11=55 +FCLASS=0 Well, I hope the above suggests something, or that you can provide me with some other tests or how I can get information that may be useful. -- Lane ---- Lane Lester / Madison County, Georgia USA ---- Getting where I want to be with Linux...
