Is there a way to open a new terminal tab in GNOME-Terminal when working on a remote machine that is connected via ssh?

tmux (or screen, the older alternative) are great for this.

tmux lets you do both horizontal and vertical splits.

You'll probably want to customize tmux, e.g. most people like cmd-a over cmd-b as the 'prefix' key.

I use the following ~/.tmuf.conf file settings to make it work better for me:

# mdd tmux settings
bind r source-file ~/.tmux.conf \; display "Reloaded!"  # Reload with ctrl-r
set -g prefix C-a         # prefix from ctrl-b to ctrl-a
unbind C-b                # allow ctrl-b for other things
set -sg escape-time 1     # quicker responses
bind C-a send-prefix      # Pass on ctrl-a for other apps
set -g base-index 1        # Numbering of windows
setw -g pane-base-index 1  # Numbering of Panes
# bind | split-window -h    # Split panes horizontal
bind \ split-window -h    # Split panes horizontal
bind - split-window -v    # Split panes vertically
bind h select-pane -L     # Switch to Pane Left
bind j select-pane -D     # Switch to Pane Down
bind k select-pane -U     # Switch to Pane Up
bind l select-pane -R     # Switch to Pane Right
bind -r C-h select-window -t :-  # Quick Pane Selection
bind -r C-l select-window -t :+  # Quick Pane Selection
bind -r H resize-pane -L 5       # Switch to Pane Left
bind -r J resize-pane -D 5       # Switch to Pane Down
bind -r K resize-pane -U 5       # Switch to Pane Up
bind -r L resize-pane -R 5       # Switch to Pane Right
setw -g mode-mouse off           # Mouse Off
set -g mouse-select-pane off     # Mouse Off  
set -g mouse-resize-pane off     # Mouse Off
set -g mouse-select-window off   # Mouse Off
#set -g  default-terminal "screen-256color"
setw -g monitor-activity on      # Activity Alerts
set -g visual-activity on
set -g status-fg white           # Status line Colors
set -g status-bg black
setw -g window-status-fg cyan    # Window list color
setw -g window-status-bg default
setw -g window-status-attr dim
setw -g window-status-current-fg white     # Active Window Color
setw -g window-status-current-bg red
setw -g window-status-current-attr bright
set -g pane-border-fg green      # Pane colors
set -g pane-border-bg black 
set -g pane-active-border-fg white 
set -g pane-active-border-bg yellow
set -g message-fg white          # Command/Message Line.
set -g message-bg black
set -g message-attr bright
set -g status-left-length 40     # Status Line, left side
set -g status-left "#[fg=white]Session: #S #[fg=yellow]#I #[fg=cyan]#P"
set -g status-utf8 on            # Status Line, right side
set -g status-right "-------"
set -g status-interval 60        # frequency of status line updates
set -g status-justify centre     # center window list
setw -g mode-keys vi             # vi keys to move 
unbind v                         # Open panes in same directory as tmux-panes script
unbind n
bind v send-keys " ~/tmux-panes -h" C-m
bind n send-keys " ~/tmux-panes -v" C-m
unbind Up                        # Maximizing and Minimizing...
bind Up new-window -d -n tmp \; swap-pane -s tmp.1 \; select-window -t tmp
unbind Down
bind Down last-window \; swap-pane -s tmp.1 \; kill-window -t tmp
bind P pipe-pane -o "cat >>~/#W.log" \; display "Toggled logging to ~/#W.log"
# Make keys for copy mode be like vi
unbind [
bind Escape copy-mode
unbind p
bind p paste-buffer
bind -t vi-copy 'v' begin-selection
bind -t vi-copy 'y' copy-selection

I also set the following aliases (in my ~/.bash_aliases file) to let me switch between scrolling and being able to copy text:

alias tof='tmux set -g mode-mouse off'
alias ton='tmux set -g mode-mouse on'
