Thread: can anyone advise on IPv4 and IPv6 issues

-

i'm having problems slow ssh file transfers on internal network.

i've read hints linux using ipv6 can slow.

1) how can tell protocol being used interface ?
2) how can tell ubunutu not use ipv6 internal addresses.

fwiw using ipv4 address formats connect machines ...

downstairs : 192.168.1.102
upstairs : 192.168.1.98

upstairs machine has 2nd interface, set 192.168.0.2

when connect downstairs upstairs, it's ssh myname@192.168.1.98

from understanding ipv6 isn't being used widespread @ yet.
know ubuntu supports ipv6, won't use unless manually specified.

chances no, not using ipv6.
if want check, use ifconfig in terminal.
if eth0 (or whatever interface use) has ipv4 address, (192.168.1.100 etc) using ipv4

wireshark show protocols used.

salve, prima di installare joomla, vorrei porvi tre semplici domande: 1) l'ultima versione in italiano di joomla, supporta questo template prodotto da gavik? loro scrivono che non è un semplice template, ma una vera e propria suite, ma vorrei una vostra opinione. qui sono descritte le funzioni della suite. 2) per sfruttare gli elementi che si vedono nella pagina, ad esempio quello in alto sinistra dove scorrono le notizie, occorre installare qualche componente aggiuntivo? 3) futuri upgrade alla piattaforma joomla, potranno inficiare il funzionamento o la compatibilità del template? vi ringrazio anticipatamente della disponibilità. 1) non vedo nulla di particolare se non una miriade di posizioni per blocchi 2) è un modulo se non sbaglio pagamento, ma adesso non ricordo bene 3) no. ti ricordo che devi installare joomla  1.0.12 Board index Joomla!

SD Datastring Convention

i wondering if there preferred convention appending data logged?  see standard sd example uses: code: [select] void loop() {   // make string assembling data log:   string datastring = "";   // read 3 sensors , append string:   (int analogpin = 0; analogpin < 3; analogpin++) {     int sensor = analogread(analogpin);     datastring += string(sensor);     if (analogpin < 2) {       datastring += ",";     }   } creating string called datastring, , appending it, have seen in forums string not liked.  around this, code data logging looks this: code: [select] void sdupdate() {   datetime = rtc.now();   unsigned int hour = now.hour();   unsigned int minute = now.minute();   unsigned int second = now.second();   char datastring[100] = "";   char char_current_pay[15] = "";   char char_overall_pay[15] = ""; ...
