I tried with novnc and tigervnc from a fedora 17 laptop.

Let me know how to test further in case.

Did you make sure that the mentioned port was open in the host firewall?

Just for the note and for others not doing the same "stupid" things like me.... I used this command vncviewer 192.168.1.102 ::5902 note the space between ip and ::5902 This way it seems the ip is totally ignored without returning any syntax error and so it implicitly tries localhost So clearly any client that tries to connect fails (if it is not a vnc server on that port itself, obviously...) And carefully reading the man page helps too: vncviewer [options] [host][::port] Instead if for example I install vncviewer and run the same command from the node itself it succeeds.... ;-) The correct command without the space vncviewer 192.168.1.102::5902 completes correctly I understood this noticing the "127.0.0.1" when prepending the "strace" command from the client and the wrong syntax: open("/etc/host.conf", O_RDONLY|O_CLOEXEC) = 3 fstat(3, {st_mode=S_IFREG|0644, st_size=9, ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fa457040000 read(3, "multi on\n", 4096) = 9 read(3, "", 4096) = 0 close(3) = 0 munmap(0x7fa457040000, 4096) = 0 futex(0x38785b5ae0, FUTEX_WAKE_PRIVATE, 2147483647) = 0 open("/etc/hosts", O_RDONLY|O_CLOEXEC) = 3 fstat(3, {st_mode=S_IFREG|0644, st_size=250, ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fa457040000 read(3, "127.0.0.1 localhost localhost."..., 4096) = 250 read(3, "", 4096) = 0 close(3) = 0 munmap(0x7fa457040000, 4096) = 0 socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 3 connect(3, {sa_family=AF_INET, sin_port=htons(5902), sin_addr=inet_addr("127.0.0.1")}, 16) = -1 ECONNREFUSED (Connection refused) close(3) = 0 ALso because connecting from the node itself with the wronh syntax I got the ESTABLISHED on localhost ip.....
