Tigervnc viewer - save password for remote machine?


A recent update to Tigervnc on CentOS 7 server broke my connections from vinagre on my old CentOS 6 machine to the CentOS 7 machines. It has to do with the encryption of the connection I believe. I CAN connect from 6 to 7 using Tigervnc Client on CentOS 6 so that is a possible solution. However...

Vinagre allowed me to create bookmarks for the various remote machines to which I routinely connected. Tigervnc Client, as far as I can tell, does not have a similar feature. I can achieve part of this functionality by creating launchers for each remote machine e.g.
Code:
/usr/bin/vncviewer taylor16:1
to connect to machine taylor16 with my desktop (:1). Problem is, I am prompted for the password each time. I am looking for a way to save the password or use a key file or something like that to eliminate the need to enter a password each time. Any ideas?

TIA,

Ken

I'm not a VNC user, so I might be just throwing ideas here. CentOS 7 update related to encryption makes vinagre unable to connect. That is a likely cause as vinagre might still be using deprecated ciphers or SSLv3.

- Any custom vinagre configs, or did you check its global config for any reference to deprecated protocols and ciphers?
- try to run a verbose vinagre from a terminal
- or you can strace it.
- I used KDE's vnc client which I can't remember the name long time ago and I kinda liked it.

Thanks c0wb0y,

I have nothing custom configured in vinagre, nor do I see where I can configure much of anything. The version of vinagre on Ubuntu Mate 16.04 (vinagre 2.28.1) connects to the CentOS 7 machines just fine.

At the moment I am experimenting with rolling back the last tigervnc update. For my purposes - occasional use on a home LAN - I can probably get along with a patch out of date. All of this might motivate me to setup tigervnc to work across an ssh tunnel.

Or X over SSH, maybe?

For the time being I have restored the machines from a Clonezilla snapshot of the OS partition from a couple months back, excluded tigervnc from updates and then updated everything else. I am also playing with tigervnc client. I have a "drawer" menu created on my CentOS 6 machine with an icon for each remote machine. I still have to enter the pasword to connect but I guess that is not too bad of a plan B. Some day I need to upgrade my main PC to CentOS 7. That will be a lot of work so I am waiting until I get a new machine - someday.
