Moreover if you want to write portable code, you probably should not depend on the LDAP server being able to return unlimited entries. . . . → Read More: Using LDAP Paged Controls with Python I had never heard of this until I ran into working on a recent project. In “bash” you can open sockets: exec file-descriptor<>/dev/tcp/IP-or-hostname-here/port so for example: exec 3<>/dev/tcp/192.168.1.100/23 would open port 23 (telnet) to IP “192.168.1.100” for read and write (the “<>”) on file descriptor “3” (remember descriptors 0, 1, and . . . → Read More: Bash TCP programming hack!? |
