Description Pekka Pietikäinen 1999-04-11 05:28:53 EDT

connecting (pp):~ >telnet evil.netppl.fi
Trying 0.0.0.0...
Connected to evil.netppl.fi.
Escape character is '^]'.

Red Hat Linux release 5.9.7 (Starbuck)

(so it connects to localhost instead, works fine when
using a IP address)

here's the ltrace output
inet_aton("evil", 0xbffff65c)                     = 0
gethostbyname("evil")                             =
0x40145ab0
strncpy(0x08057a40, "evil.netppl.fi", 64)         =
0x08057a40
__bzero(0xbffff658, 16, 0xbffff6f8, 1, 0)         = 0
getservbyname(0x0805433e, 0x08054324, 0xbffff6f8, 1, 0) =
0x40145bd0
inet_ntoa(NULL)                                   =
"0.0.0.0"
printf("Trying %s...\r\n", "0.0.0.0"Trying 0.0.0.0...
