vncviewer--unable connect to socket: No route to host (113)

[v-jaden]

Hi ,everyone

I am new to linux world.
I had built up two linux server , one FC15 ,and other is RHEL 6, these two machines are in the same subnet.

I can SSH to FC 15 with no problem ,but vncviewer ,i type the FC15's IP ,and they ,i got the error "vncviewer--unable connect to socket: No route to host (113)" ,why ?

On FC15, i had enabled Remote Desktop , and created a VNC configuration file.

Thanks

Firewall? Try telneting to the VNC port on the FC15 box or nmap the FC15 box from the RHEL6 box and see if the port is open. If it's not, try checking out the iptables config on the RHEL6 box.

i do a iptables -F ,and then problem resolved

By the way ,another question. Don't know why vsftpd service can't start

i do a "/etc/init.d/vsftpd start -->500 OOPS cannot read the config file: start

but the vsftpd.conf file exist under /etc/vsftpd/ folder and i tired this
"chkconfig --level 35 vsftpd on
service vsftpd start"

still fail to start the service

How to resolve this problem

thanks

Word of warning - iptables -F flushes all rules. Depending on the default chain policies (which I'm assuming are set to accept as you can now connect), that could leave you boxes wide open.

I use vsftpd myself, albeit on debian servers and I think the set up is slightly different in terms of config file locations etc...

But - are you trying to start as root? Check permissions on the config file. Try copying vsftpd.conf to /etc/ (debian default - not sure about RH)

You could try (as root)

strace /etc/init.d/vsftpd start

and look for information about the config file it is *trying* to load.

Thanks for your information .. Because all these two machines are test purpose ,so i use the -F option in iptables

And for the vsftpd service .. i resolved by enter the "/etc/init.d/" folder ,and run command "./vsftpd start "

can anyone tell me why i should need to add the "./"

Thanks

re the OOPS error, are you sure you did not do /usr/sbin/vsftpd start? That's the only way I could replicate your error.

as to why the "./", that just tells bash that the file you are running is in the current directory (/etc/init.d/). If the file were in your path (say in /bin), then you would not need the "./". But you should not have to start it that way, I think something else is wrong.

Make sure your initscript is not a symlink:

ls -l /etc/init.d/vsftpd

Confirm the state of your vsftp package:

rpm -qV vsftpd

As a side not, you can enable the vsftp daemon to auto-start upon reboot, so that you don't have to manually run it:

chkconfig vsftpd on

EDIT: Sorry, didn't see your comments about already trying chkconfig. Which box is this, the F15 or the RHEL6? What is the exact error that you get after 'service vsftpd start'?
