Dobry den,

 v urcitych verzich distribuce debian a distribuci nad debianem postavenych jsme zaregistrovali obcasne problemy v komunikaci se serverem, pokud byla zapla kontrola timestamps. Vase nastaveni zjistite pomoci "cat /proc/sys/net/ipv4/tcp_timestamps". Pokud vam system vypise jednicku, mate kontrolu zaplou. V tom pripade ji zkuste vypnout prikazem "echo 0 > /proc/sys/net/ipv4/tcp_timestamps".
