Configure individual interfaces. Configure individual terminal lines. 2. Refer to the exhibit. Host A attempts to establish a TCP/IP session with host C.

The packet inside the captured frame has an IP source address 192.168.7.5, and the destination IP address is 192.168.219.24. At which point in the network was this packet captured? leaving host A leaving ATL leaving...
Joshua Weinberg's answer is mostly correct, however the Ox prefix is optional when scanning hexadecimal integers. If you have a string in the format #01FFFFAB, you can still use an NSScanner, but you can simply skip the first character.
ReplyDeleteunsigned result = 0;
NSScanner *scanner = [NSScanner scannerWithString:@"#01FFFFAB"];
[scanner setScanLocation:1]; // bypass '#' character
[scanner scanHexInt:&result];
you can use NSScanner for this
ReplyDeleteint outVal;
NSScanner* scanner = [NSScanner scannerWithString:@"0x01FFFFAB];
[scanner scanHexInt:&outVal];
outVal will contain the int you're looking for. The 0x is optional.
strtol() is your friend.
ReplyDeleteIt converts a string to a long, and you can pass the base of the number in. Strip that # sign off first though, or pass to strtol a pointer to the first numerical character.
