(4.3 BSD uses 30, 4.2 used 15). The maximum possible value of this field is 255, and most Unix systems set the TTL field of ICMP ECHO_REQUEST packets to 255. This is why you will find you can ``ping'' some hosts, but not reach them withtelnet(1) orftp(1). In normal ...

find it useful to employ the TCP_CORK option, described in tcp(7), to minimize the number of packets and to tune performance. In Linux 2.4 and earlier, out_fd could also refer to a regular file; this possibility went away in the Linux 2.6.x kernel series, but was ...
