I would first verify that Xvnc is not only listening on localhost.
Two ways, From euripide (the "remote", ie: the server)
1. nmap
nmap -v -n -Pn -p5900-5906 euripide
Starting Nmap 7.70 (
https://nmap.org ) at 2020-02-16 11:46 CET
Initiating Connect Scan at 11:46
Scanning euripide (193.52.235.60) [7 ports]
Discovered open port 5901/tcp on 193.52.235.60
Completed Connect Scan at 11:46, 0.00s elapsed (7 total ports)
Nmap scan report for euripide (193.52.235.60)
Host is up (0.00037s latency).
Other addresses for euripide (not scanned): fe80::de89:7b2c:9cf1:d1c9
PORT STATE SERVICE
5900/tcp closed vnc
5901/tcp open vnc-1
5902/tcp closed vnc-2
5903/tcp closed vnc-3
5904/tcp closed unknown
5905/tcp closed unknown
5906/tcp closed unknown
Read data files from: /usr/bin/../share/nmap
Nmap done: 1 IP address (1 host up) scanned in 0.03 seconds
2. or lsof
lsof -p $(pidof Xvnc) | grep LISTEN
Xvnc 5308 pdupre 6u IPv4 145831 0t0 TCP *:5901 (LISTEN)
Xvnc 5308 pdupre 7u IPv6 145832 0t0 TCP *:5901 (LISTEN)
Should give something like
Xvnc <snip> TCP *:5901 (LISTEN)
and not:
Xvnc <snip> TCP localhost:5901 (LISTEN)
You can also check the arguments given to Xvnc by vncserver:
ps -wp $(pidof Xvnc)
PID TTY TIME CMD
5308 ? 00:00:00 Xvnc
PS: If you have SSH access, I suggest to restrict Xvnc to localhost
and use:
vncviewer -via euripide :1
vncviewer -via euripide :1 vncviewer -via
euripide :0
donne le meme resultat:
ssh: Could not resolve hostname euripide.u-bourgogne.fr:1: Name or service not known
ssh: Could not resolve hostname euripide.u-bourgogne.fr:0: Name or service not known
