It's not a bug and man page ping6(8) mentions it: --------------- -I interface For IPv6, when doing ping to a link-local scope address, link specification (by the '%'-nota‐ tion in destination, or by this option) is required. ---------------
However the error message "connect: Invalid argument" (with no help) is very confusing and I believe many people need to google this issue. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to iputils in Ubuntu. https://bugs.launchpad.net/bugs/1075424 Title: ping6 does not understand IPv6 addresses Status in iputils package in Ubuntu: Invalid Bug description: I cannot figure out what the problem is, but ping6 doesn't understand IPv6 addresses, except for the "local" IPs. $ ifconfig eth0 eth0 Link encap:Ethernet HWaddr 70:5a:b6:<blah> inet addr:192.168.0.25 Bcast:192.168.0.63 Mask:255.255.255.192 inet6 addr: fe80::725a:b6ff:fef3:4d60/64 Scope:Link $ ping6 ::1 -c 1 PING ::1(::1) 56 data bytes 64 bytes from ::1: icmp_seq=1 ttl=64 time=0.074 ms $ ping6 fe80::725a:b6ff:fef3:4d60 connect: Invalid argument strace: connect(3, {sa_family=AF_INET6, sin6_port=htons(1025), inet_pton(AF_INET6, "fe80::725a:b6ff:fef3:4d60", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = -1 EINVAL (Invalid argument) dup(2) = 4 fcntl(4, F_GETFL) = 0x8002 (flags O_RDWR|O_LARGEFILE) fstat(4, {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 12), ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7ff83d761000 lseek(4, 0, SEEK_CUR) = -1 ESPIPE (Illegal seek) write(4, "connect: Invalid argument\n", 26connect: Invalid argument ) = 26 close(4) I haven't been able to ping any IPv6 addresses for about a year.
