Hi,
I am trying to install vncserver on a fedora system.
I am wondering how can i get the vncserver rpm to install.
I am not having it in the yum repository. (by the way is vncserver free ?)
How could i download the rpm and install it ?
Please advice me on this.
Thanks in advance!
for example you can search vncserver in this site like below eg fedora 10..
(probably it requires xorg-x11-xauth for x11 forwarding to server)
and you can try it with vnc-client.
http://rpm.pbone.net/index.php3/stat/4/idpl/13677028/dir/fedora_10/com/vnc-server-4.1.3-1.fc10.i386.rpm.html
and then you can look to look Requires : section and then collect another dependencies packages.lastly install all packages and go on 
or
directly install from realvnc.com.this rpm has both server and client.

Hi ygemici, thanks for the reply with link.
I tried free edition of vncserver from realvnc and did following.
downloaded vnc-4_1_3-x86_linux[1].tar.gz from realvnc and winscp'ed to fedora box and untar it with following command
tar -zxvf vnc-4_1_3-x86_linux[1].tar.gz
this created a dir called "vnc-4_1_3-x86_linux[1]"
cd to that dir and
./vncinstall /usr/local/bin
this copied vncserver, vncpasswd,vncconfig etc files to /usr/local/bin
cd to /usr/local/bin and then the following
[root@testbox bin]# ./vncserver
You will require a password to access your desktops.
Password:
Verify:
xauth: creating new authority file /root/.Xauthority
New testbox.local:1 (root)' desktop is testbox.local:1
Creating default startup script /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/testbox.local:1.log
[root@testbox bin]# echo $?
0
But i haven't found /etc/sysconfig/vncservers file to edit.
And rpm -qa |grep vnc doesnt show the installed rpm.
(But it does created .vnc directory in /root )
What went wrong?
you dont see rpm list because of you dont install a rpm package..
i guess that packages comes where from realvnc.com does not includes vncservers file.
you must install vnc-server rpm alternative sources for this.
on the other hand you can resume with this package so.
(you should not use vnc for root user.there is may some securiy vulnerabilitys especially while in auth levels.)
firstly on the server start vncpasswd for create a vnc password for test user in server which connect on desktop.
$ su - test
$ vncpasswd
$ x0vncserver -PasswordFile /home/test/.vnc/passwd
and the on vncclient start vncviewer for example
# vncviewer -FullColour vncserver -ViewOnly -geometry 1024x768

Hi ygemici, thanks again.
I tried this
[vct@console-0124 ~]$ vncpasswd
Password:
Verify:
[vct@console-0124 ~]$ x0vncserver -PasswordFile /home/vct/.vnc/passwd
x0vncserver: unable to open display ""
~ImageCleanup called
[vct@console-0124 ~]$ echo $?
1
[vct@console-0124 ~]$
looks this was not successful.
when i opened vncviewer on windows laptop to connect i got
VNC viewer error: unable to connect to host: A socket operation was attempted to an unreachable host. (10065)
I still dint find /etc/sysconfig/vncservers file to edit and
[vct@console-0124 ~]$ vncserver
New 'console-0124.local:1 (vct)' desktop is console-0124.local:1
Starting applications specified in /home/vct/.vnc/xstartup
Log file is /home/vct/.vnc/console-0124.local:1.log
but
[vct@console-0124 ~]$ service vncserver status
vncserver: unrecognized service
Not sure where is the problem.
Please suggest me a solution to this.
Thanks in advance!
The version of vncserver you installed is not integrated with Fedora 10. it is a standalone version and has to be treated as such. Therefore commands such as
service vncserver status
will not work.
If you want a Fedora 10 enabled version, download and install the appropriate RPMs from /pub/archive/fedora/linux/releases/10. Look under "Everything/i386/os/Packages".
Hi fpmurphy,
Thanks for the reply.
I downloaded & installed vnc-server-4.1.2-35.fc10.x86_64.rpm as root.
and made following change in /etc/sysconfig/vncservers file
VNCSERVERS="1:vct"
VNCSERVERARGS[1]="-geometry 800x600 -nolisten tcp -nohttpd -localhost"
as vct user set vncpasswd
and as root user started vncserver by
service vncserver start
root@console-0124 .vnc]# service vncserver start
Starting VNC server: 1:vct
New 'console-0124.local:1 (vct)' desktop is console-0124.local:1
Starting applications specified in /home/vct/.vnc/xstartup
Log file is /home/vct/.vnc/console-0124.local:1.log
[ OK ]
then started vncviewer and tried to connect as console-0124.local:1
then i got error as
unable to resolve host by name: the requested name is valid and was found in the database, but it does not have the correct associated data being resolved for. (11004)
.
and when i tried to connect via ip address then i got
unable to connect to host: A socket operation was attempted to an ureachable host (10065)
what is wrong.
Is this because of my old incorrect rpm installations ?
xstart file in /home/vct/.vnc is as follows
[vct@console-0124 .vnc]$ more xstartup
#!/bin/sh
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
twm &
here i did not find following lines to uncomment
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc
and xstartup file in roots home dir is also same.
what went wrong.
Thanks in advance!
any help!!!!!!!
x0vncserver: unable to open display ""
you have to a DISPLAY for x11 forwarding to view data.
so you must x11 forward to a X11 source (if you work windows,use xming or xmanager..)
or you must connect a linux console.
for other problem
first remove "-nohttpd" from vncservers file.some versions does not support this.
# grep nohttpd /home/vct/.vnc/console-0124.local:1.log
and then restart (probably this is not the main problem)
# service vncserver restart
after than can you write this log in forum after we can examine this.
# cat /home/vct/.vnc/console-0124.local:1.log
and you can check vnc service is running?
# x=$(sed -n 's/.*vncPort = \([0-9]*\).*/\1/p' /usr/bin/vncserver) ; nc -z `hostname -s` $x-$((x+110)) ; netstat --protocol=inet -lp|grep -i vnc
most importantly you must be sure you have access to vncserver!
..you maybe access to vnc port but following the data transfer is problem because of blocked your 3way hand-shake level while before beginning communication via tcp sockets.therefore appropriate sockets do not pass the establish state and kernel network layer genarates an error message to vnc and vnc convert it to own message and echoes ur tty..
you can check access to vncserver via vncPort that defined above
# telnet vncserver vncPort

hi lramsb4u
can you write this.
# cat /home/vct/.vnc/xstartup
# cat /etc/redhat-release
after that
# vncserver -kill :1
# service vncserver restart
and then let we look again for log file
# cat /home/vct/.vnc/console-0124.local:1.log

FontPath "/usr/share/fonts/X11/Type1/"
FontPath "/usr/share/fonts/X11/75dpi/"
FontPath "/usr/share/fonts/X11/100dpi/"
and
# service xfs restart
if there is not anything in "/usr/share/fonts/X11/, you must install xorg-x11-fonts* rpms.
after all process then retry
on server
# service vncserver restart
on client
# vncviewer :1 -FullScreen
if you get still error
try this with xstartup
#!/bin/sh
# Uncomment the following two lines for normal desktop:
