conserver is a centralized serial server that keeps a persistent serial session open and allows multiple users to access the same console at a time. See http://www.conserver.com/
The service is running on a VM in RHEV on conserver.front.sepia.ceph.com. It is configured to allow passwordless access to any IP on the 172.21.0.0/20 network. (This includes VPN clients since they are routed through gw.front.sepia.ceph.com)
Fedora and Ubuntu have pre-built packages available. yum/apt-get install conserver-client
CentOS and RHEL users will need to install the epel repo. Then, yum install conserver-client --enablerepo=epel
MacOS users can use http://brew.sh/ to install via: brew install conserver
After installing the client package, copy and paste the following into a terminal on your workstation.
cat <<EOF > ~/.consolerc
config * {
master conserver.front.sepia.ceph.com;
port 3109;
}
EOF
To access a serial console, run, for example, console smithi001
Conserver clients can control serial sessions using a combination of Ctrl+e c commands.
For Example: To take over write access of a console, enter Ctrl+e, then c, then f. Do not hold Ctrl!
Here's a list of the available commands:
[Enter `^Ec?' for help] [help] . disconnect ; move to another console a attach read/write b send broadcast message c toggle flow control d down a console e change escape sequence f force attach read/write g group info i information dump L toggle logging on/off l? break sequence list l0 send break per config file l1-9 send specific break sequence m display the message of the day n write a note to the logfile o (re)open the tty and log file p playback the last 60 lines P set number of playback lines r replay the last 20 lines R set number of replay lines s spy mode (read only) u show host status v show version info w who is on this console x show console baud info z suspend the connection | attach local command ? print this message <cr> ignore/abort command ^R replay the last line \ooo send character by octal code
