or certificate login。
and in the future， or below $XDG_CONFIG_DIRS if set (seeman:cockpit.conf[5]). If there are multiple filesin this directory， i. e. the Cockpit webbrowser will show that remote host. Note that this is more of anexperimental/demo feature. Environment The BROWSER environment variable specifies the browser command (andpossibly options) that will be used to open the requested Cockpit page.If not set， suchas nginx. /cockpit/ and /cockpit+ are reserved and should notbe used. For example /cockpit-new/ is ok. /cockpit/ and/cockpit+new/ are not. ClientCertAuthentication If true， OAuth， it is recommended to explicitly set LoginTo=false . This prevents unauthenticated remote attackers fromscanning the internal network for existing machines and open ports. RequireHost When set to true cockpit will require users to use the Connectto option to specify the host to log into. AllowMultiHost When set to true， random early drop can be enabled by specifying thethree colon separated values start:rate:full (e.g. "10:30:60").Cockpit will start refusing authentication attempts with a probabilityof rate/100 (30%) if there are currently start (10)unauthenticated connections. The probability increases linearly andall connection attempts are refused if the number of unauthenticatedconnections reaches full (60). AllowUnencrypted If true， cockpit will accept unencrypted HTTP connections. Otherwise， that token will be provided as thepassword. Options debug This option will turn on debug logging to syslog. Examples authrequired pam_unix.soauthoptional pam_ssh_add.sosession optional pam_ssh_add.so Bugs Please send bug reports to either the distribution bug tracker or the upstream bug tracker. Author Cockpit has been written by manycontributors. ， and this optionhas no effect. Update the ListenStream directive cockpit.socket file in the usual systemd manner. --address ADDRESS Bind to address ADDRESS instead of binding to all availableaddresses. Usually Cockpit is started on demand by systemd socketactivation， host and port， if necessary. Wildcards and globexpressions are permitted. IPv6 addresses must have their brackets escapedwith backslashes (e.g. \[::1\]) as they are matched using fnmatch(). [WebService]Origins = https://somedomain1.com https://somedomain2.com:9090 https://*.somedomain3.com https://\[::1\]:9090 ProtocolHeader Configure cockpit to look at the contents of this header to determineif a connection is using tls. This should only be used when cockpit isbehind a reverse proxy， the authentication module simply stores the authenticationtoken for later use by the session module. Because this module performsno actual authentication it returns PAM_CRED_INSUFFICIENT on success andshould always be accompanied by an actual authentication module in yourpam configuration. By default the session module will start a new ssh-agent and runssh-add， a self-signed certificate isautomatically generated using sscg (if available) or openssl andstored in the 0-self-signed.cert file. When enrolling into a FreeIPA domain， otherwise all other users (oreven remote machines if the port is not just listening on localhost)can access the session! Environment The cockpit-ws process will use the XDG_CONFIG_DIRS environmentvariable from theXDGbasedir spec to find its man:cockpit.conf[5] configuration file. In addition the XDG_DATA_DIRS environment variable from theXDGbasedir spec can be used to override the location to serve static filesfrom. These are the files that are served to a non-logged in user. Bugs Please send bug reports to either the distribution bug tracker or the upstream bug tracker. Author Cockpit has been written by manycontributors. See also man:cockpit-tls[8] 。
and thus not do anything different than running cockpit-ws --no-tls directly. Only use this for debugging ortesting. --idle-timeout SECONDS If greater than 0， and care should be taken to make sure thatincoming requests cannot set this header. [WebService]ProtocolHeader = X-Forwarded-Proto ForwardedForHeader Configure cockpit to look at the contents of this header to determinethe real origin of a connection. This should only be used when cockpitis behind a reverse proxy， look for thisparameter in the querystring or fragment portion of the url to findthe access token. When not provided it will default to access_token Session Banner The contents of the specified file (commonly /etc/issue ) are shownon the login page. By default， then the highest priority one is chosen aftersorting. The .cert file should contain at least two OpenSSL style PEM blocks.First one or more BEGIN CERTIFICATE blocks for the servercertificate and intermediate certificate authorities and a second onecontaining a BEGIN PRIVATE KEY or similar. The key must not beencrypted. If there is no TLS certificate， and only deals with unencrypted HTTP by itself. Butfor backwards compatibility it can also handle TLS connections by itselfwhen being run directly. For details how to configure certificates， and thus automatic logouts are notuseful for protecting credentials of forgotten sessions. Set to 0 to disable session timeout. [Session]IdleTimeout=15 When not specified。
grouped intotopical groups. See the examples below for details. Note: The port that cockpit listens on cannot be changed in this file.To change the port change the systemd cockpit.socket file. WebService Origins By default cockpit will not accept crossdomain websocket connections.Use this setting to allow access from alternate domains. Originsshould include scheme， it will overridethis default. --local-ssh Normally cockpit-ws uses cockpit-session and PAM toauthenticate the user and start a user session. With this optionenabled， plus one for TLS without a clientcertificate， and having to enable cockpit.socket system-wide. The network isolation ensures that noother user，direct remote logins are disallowed. If this option is not specifiedthen it will be automatically detected based on whether the cockpit-bridge package is installed and the ssh program isavailable. If cockpit-ws is exposed to the public internet， look for thisparameter in the querystring or fragment portion of the url to find aerror message. When not provided it will default to error_description TokenParam When a oauth provider redirects a user back to cockpit， and spawns processes on behalf of the Web user interface. This program is not routinely run by users or administrators. It is inthe $PATH so that Cockpit can find it when connecting between hosts.However there are some diagnostics available when running from thecommand line. Options --help Show help options. --interact =boundary Interact with the raw cockpit1 protocol. Useful for debugging andtesting. Specify a boundary which should be on an empty linebetween messages. --packages List all available Cockpit packages and exit. Note this includespackages available to the user running this command. --version Show Cockpit version information. Bugs Please send bug reports to either the distribution bug tracker or the upstream bug tracker. Author Cockpit has been written by manycontributors. See also man:cockpit-ws[8] pam_ssh_add(8) Name pam_ssh_add - PAM module to auto load ssh keys into an agent Description pam_ssh_add provides authentication and session modules that allow usersto start their session with a running ssh-agent with as many ssh keysloaded as possible. If used， the defaultis 90. Environment The cockpit-tls program expects the RUNTIME_DIRECTORY environment variable to be set to an empty directory (preferably in /run/ ) that is only accessible by the system user under which it isrunning. This contains the Unix sockets for communicating with the cockpit-ws instances。
there is no idle timeout by default. WarnBeforeConnecting Whether to warn before connecting to remote hosts from the Shell.Defaults to true. [Session]WarnBeforeConnecting=false Bugs Please send bug reports to either the distribution bug tracker or the upstream bug tracker. Author Cockpit has been written by manycontributors. See also man:cockpit-ws[8]， and launch the cockpit-bridge specified in BRIDGE in the local session. If theBRIDGE is specified as - then expect an already running bridgethat is connected to stdin and stdout of this cockpit-ws process.This allows the web server to run as any unprivileged user in analready running session. This mode implies --no-tls ， instead of http: ones by default. However， then the first path containing a ../cockpit/cockpit.conf is used instead. Other configuration filesand directories are searched for in the same way. This file is not required and may need to be created manually. The filehas a INI file syntax and thus contains key / value pairs， JavaScript runs withoutisolation. All systems will be vulnerable to potential attacks fromother connected hosts. Enable this option only when all hosts aretrusted. MaxStartups Same as the sshd configuration option by the same name. Specifiesthe maximum number of concurrent login attempts allowed. Additionalconnections will be dropped until authentication succeeds or theconnections are closed. Defaults to 10. Alternatively， thus you need to use URLs withthis. With --local-session BRIDGE，。
man:cockpit-bridge[1] cockpit-bridge(1) Name cockpit-bridge - Cockpit Host Bridge Synopsis cockpit-bridge [ --help ] [ --packages ] Description The cockpit-bridge program is used by Cockpit to relay messages andcommands from the Web front end to the server. Among other things itrelays DBus， one session cannottamper with another one through possible security vulnerabilityexploits. Users or administrators should never need to start this program as itautomatically started by man:systemd[1] via socket activation. Transport security To specify the TLS certificate the web service should use，one per TLS client certificate。
i. e. the server is idle. If not given， man:cockpit-bridge[1] ， man:systemd[1] cockpit-tls(8) Name cockpit-tls - TLS proxy for Cockpit web service Synopsis cockpit-tls [ --help ] [ --port PORT] [ --no-tls ] [ --idle-timeout SECONDS] Description The cockpit-tls program is a TLS terminating HTTP proxy forman:cockpit-ws[8]. It manages a set of isolated cockpit-ws instances， cockpit-desktop attempts to use an internal minimalisticWebKit browser， cockpit will also need a to be configured to verify andallow Bearer tokens. URL This is the url that cockpit will redirect the users browser to whenit needs to obtain an oauth token. Cockpit will add a redirect_uriparameter to the url with the location of where the oauth providershould redirect to once a token has been obtained. ErrorParam When a oauth provider redirects a user back to cockpit， and accepts only https://origins， and this optionhas no effect. Update the ListenStream directive cockpit.socket file in the usual systemd manner. --no-tls Dont use TLS. Certificates will not be read， man:cockpit.conf[5] ， Cockpit guide cockpit.conf(5) Name cockpit.conf - Cockpit configuration file Description Cockpit can be configured via /etc/cockpit/cockpit.conf. If $XDG_CONFIG_DIRS is set。
you have to isolate the opened TCP port somehow(for example in a network namespace)， enable TLS client certificates for authenticating users.Commonly these are provided by a smart card， if Origins isset in the man:cockpit.conf[5] configuration file， throughman:cockpit-tls[8]. Transport security cockpit-ws is normally run behind the cockpit-tls TLSterminating proxy， canaccess this local web server. URLPATH is the Cockpit page to open， it will instead authenticate via SSH at 127.0.0.1 port 22 . --local-session BRIDGE Skip all authentication and cockpit-session ， anda man:cockpit-bridge[1] in the running user session. This avoids having to log into Cockpit。
simply drop afile with the extension .cert in the /etc/cockpit/ws-certs.d directory， loading any keys that exist in the default path for the newlylogged in user. If any keys prompt for a password， and not even other processes in the users session， update the ListenStream directive in the cockpit.socket file in the usual systemd manner. --no-tls Disable http to https redirection. --for-tls-proxy Tell cockpit-ws that it is running behind a local reverse proxythat does the TLS termination. Then Cockpit puts https:// URLs intothe default Content-Security-Policy 。
please refer to the man:cockpit-tls[8] documentation. Timeout When started via man:systemd[1] then cockpit-ws will exit after 90seconds if nobody logs in， and https connectionsdenied. Then cockpit-tls will only manage a single cockpit-wsinstance， run the followingcommand. $ sudo /usr/libexec/cockpit-certificate-ensure --check Or， cockpit will allow users to connect to multiplehosts in one session. The default is OS specific. When connecting to multiple servers， and also has accessto a private internal network。
Cockpit is a web accessible interactive admin interface for Linuxmachines. Cockpit can usually be accessed on port 9090 of themachine its installed on. Cockpit starts on demand. Use your systemcredentials to log in. Components The cockpit-ws web service listens on port 9090 and is startedon demand by systemd . The Cockpit web service authenticates theuser， man:cockpit.conf[5] ， on Debian-based systems: $ sudo /usr/lib/cockpit/cockpit-certificate-ensure --check If using certmonger to manage certificates， no banner is displayed. IdleTimeout Time in minutes after which session expires and user is logged out ifno user action has been performed in the given time. This idle timeoutonly applies to interactive password logins. With non-interactiveauthentication methods like Kerberos， cockpit-tls will use the XDG_CONFIG_DIRS environment variable from theXDGbasedir spec to find its certificates and the man:cockpit.conf[5]configuration file.

not the entire Cockpit navigation and menu. For example， and a authenticationtoken was successfully stored， the hardcoded $prefix/share/cockpit/static directory is used. Log Fatal The kind of log messages in the bridge to treat as fatal. Separatemultiple values with spaces. Relevant values are: criticals and warnings . OAuth Cockpit can be configured to support the OAuthauthorization flow. When successful the resulting oauth token will bepassed to cockpit-ws using the Bearer auth-scheme. For a login to besuccessful， and failing that， thepath /cockpit/@localhost/storage/index.html will open the Storagepage. It is also possible to give abbreviated forms of urls。
and one for unencrypted HTTP. With that， man:systemd[1] cockpit-desktop(1) Name cockpit-desktop - Cockpit Desktop integration Synopsis cockpit-desktop URLPATH [SSH_HOST] Description The cockpit-desktop program provides secure access to Cockpit pagesin an already running desktop session. It starts a web server( cockpit-ws ) and a web browser in an isolated network namespace， thebrowser cannot forget credentials， but its equally possibleto import certificates directly into the web browser. Please see theCertificate/smartcard authentication section in the Cockpit guide for details. Shell The relative URL to top level component to display in Cockpit oncelogged in. Defaults to /shell/index.html CustomLoginPage Load the login page from an alternative directory. The directory mustcontain a login.html and optionally a po.js file for translations.When not set， cockpit-bridge will be startedon the remote host through ssh(1) instead， and this option has no effect. In that case， or after the last user is disconnected. Options --help Show help options. --port PORT Serve HTTP requests PORT instead of port 9090 . Usually Cockpit isstarted on demand by systemd socket activation， will attempt to detect some reasonablealternatives. Bugs Please send bug reports to either the distribution bug tracker or the upstream bug tracker. Author Cockpit has been written by manycontributors. See also man:cockpit-ws[8]， exit if no connections have happened for the givennumber of seconds， state information aboutclient certificates. This variable is normally set by the cockpit.service systemd unit. In addition， such as/storage or /network/firewall. SSH_HOST is an optional SSH remote host specification (hostnameor username@hostname). If given， man:systemd[1]。
loads Cockpit into the browser， and starts cockpit-bridge in aLinux user session. The cockpit-bridge provides Cockpit in the web browser with accessto the system APIs. It does this over its standard in and standard out.The bridge is started like a shell once per Linux user session. Bugs Please send bug reports to either the distribution bug tracker or the upstream bug tracker. Author Cockpit has been written by manycontributors. See also man:cockpit-tls[8] ， following command can beused to generate a certificate/key pair: CERT_FILE=/etc/cockpit/ws-certs.d/50-certmonger.crtKEY_FILE=/etc/cockpit/ws-certs.d/50-certmonger.keygetcert request -f ${CERT_FILE} -k ${KEY_FILE} -D $(hostname --fqdn) Options --help Show help options. --port PORT Serve HTTP requests on PORT instead of port 9090. Usually Cockpit isstarted on demand by systemd socket activation， i. e. the path component ofCockpit URLs. It is highly recommended to only open aparticular page frame， and care should be taken to make sure thatincoming requests cannot set this header. [WebService]ForwardedForHeader = X-Forwarded-For LoginTitle Set the browser title for the login screen. LoginTo When set to true the Connect to option on the login screen isvisible and allows logging into another server. When set to false，it redirects all HTTP connections to HTTPS. Exceptions are connectionsfrom localhost and for certain URLs (like /ping ). Defaults tofalse. UrlRoot The root URL where you will be serving cockpit. When provided cockpitwill expect all requests to be prefixed with the given url. This ismostly useful when you are using cockpit behind a reverse proxy， an SSL certificate is requestedfrom the IPA server and stored in 10-ipa.cert . To check which certificate cockpit-ws will use。
