A hack to get logging information from Alcatel ADSL Modem/router
(I know this is mostly-Linux unrelated, but some people here
who use Alcatel moedm as a router, with Linux, can find it useful)
While doing a routine telnet to my modem, I've discovered that
you can get a remarkable amount of information regarding the
activity of your modem, on the fly.
This is important especially for those of us who need to
update their dynamic IP on a dynamic DNS host server
every time it is changed.
I've proviously written a script that pulls the IP from the
modem by running telnet, and let it run every 5 minutes (BTW,
I also solved the problem with identd). But now, after discovering
the logging information, I can write a daemon that waits for the
modem to report the IP change.
The logging is activated by connecting using TCP/IP to
the modem (usually 10.0.0.138), and sending the 0x11 byte:
#include
#include
#include
#include
#include
int main()
{
int sock, rc;
struct sockaddr_in sin = {0,};
char buf;
sock = socket(AF_INET, SOCK_STREAM, 0);
if (sock == -1) {
perror("sock");
return -1;
}
sin.sin_family = AF_INET;
sin.sin_port = htons(23);
sin.sin_addr.s_addr = inet_addr("10.0.0.138");
rc = connect(sock, (struct sockaddr *)&sin, sizeof(sin));
if (rc != 0) {
perror("connect");
return -1;
}
sleep(1);
recv(sock, buf, sizeof(buf), 0);
buf = 0x11;
send(sock, &buf, 1, 0);
dup2(sock, 0);
execl("/bin/cat", "/bin/cat", NULL);
return 0;
}
Running this while connecting to my ISP, I get on my side:

The D-Link DWL-650+ (CardBus and PCI versions) works on Linux, with the reversed-enginereed open source driver. It had in fact, matured greatly in the last month. http://acx100.sourceforge.net It started working only two weeks ago, when I had a few E-Mail exchanges with the lead developer of the OSS driver, Andreas Mohr <[EMAIL PROTECTED]>. We have managed to find and debug an initialization problem in the driver (which also plagued the binary version) with my CardBus card. After doing a guided change suggested by Andreas, I finally got it to work. Although it seems to work OK, I am really not satisfied with my WiFi setup. Using a D-Link DWL-900AP+ access point, it seems that the wireless connection gets completely disconnected from 20 meters away, and at a 1 meter range - the link doesn't get any faster than 6Mbit/sec. What's the point of WiFi if I can't get upstairs to my room without losing the link? -- Dan Aloni [EMAIL PROTECTED] = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

Regarding Windows drivers on Linux, I'd also like to recommend another great piece of work named ndiswrapper [1]. I ended up using ndiswrapper because the 3Com PCMCIA card 802.11g card that I ordered turned out to be a "WinModem"-like piece of hardware. And how did I let that happen? Well, it's not that I didn't check the compatibility list on the web [2], it just happens to be that the same product model ID could have two completely different versions. Just something you need to be very aware about when ordering wireless equipment, I fell on this twice. * [1] http://ndiswrapper.sourceforge.net/ * [2] http://www.linux-wlan.org/ -- Dan Aloni [EMAIL PROTECTED] = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

Oh, the "2^31 seconds are enough time for everybody",
brought to you by one or more careless UNIX designers
who might be lucky enough to be alive and 100+ years
old when this bug actually manifests.
In GNU/Linux, time_t is typedef'ed from __time_t, that
is typedef'ed from __TIME_T, that in turn typedef'ed
from __SLONGWORD_TYPE, that is defined from 'long int'.
Even today 64 bit architectures define 'long int' as
64 bit on some cases. Hopefully most 32-bit architectures
will perish until 2038. Nowadays, AMD64 slowly becomes
commodoty hardware, so I'm optimistic.
