POLIPO(1) General Commands Manual POLIPO(1) NAME
polipo - a caching web proxy SYNOPSIS
polipo [ -h | -v | -x ] [ -c config ] [ var=val ]... DESCRIPTION
Polipo is a caching HTTP proxy. It listens to requests for web pages from your browser and forwards them to web servers, and forwards the servers' replies to your browser. In the process, it optimises and cleans up the network traffic. By default, Polipo listens on TCP port 8123. Please configure your web browser to use the proxy on localhost port 8123. OPTIONS
-h Display help and exit. -v Display the list of configuration variables and exit. -x Purge the on-disk cache and exit. -c Select an alternate configuration file. var=val Change the value of a configuration variable. FILES
/etc/polipo/config The default location of Polipo's configuration file. /etc/polipo/forbidden The default location of the list of forbidden URLs. /var/cache/polipo/ The default location of the on-disk cache. /usr/share/polipo/www/ The default root of the local web space. SIGNALS
SIGUSR1 write out all in-memory objects to disk and reload the forbidden URLs file. SIGUSR2 write out all in-memory objects to disk, discard all in-memory objects, and reload the forbidden URLs file. SIGTERM, SIGINT, SIGHUP write out all in-memory objects to disk and quit. SECURITY
The internal web server will follow symbolic links that point outside the local document tree. You should run Polipo in a chroot jail if that is a problem. There is no reason to run Polipo as root. FULL DOCUMENTATION
The full manual for Polipo is maintained in a texinfo file, and is normally available through a web server internal to Polipo. Please make sure that Polipo is running, and point your favourite web browser at http://localhost:8123/ Alternatively, you may type $ info polipo at a shell prompt, or C-h i m polipo RET in Emacs.

polipo_session_selinux - Security Enhanced Linux Policy for the polipo_session processes DESCRIPTION
Security-Enhanced Linux secures the polipo_session processes via flexible mandatory access control. The polipo_session processes execute with the polipo_session_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier. For example: ps -eZ | grep polipo_session_t ENTRYPOINTS
The polipo_session_t SELinux type can be entered via the polipo_exec_t file type. The default entrypoint paths for the polipo_session_t domain are the following: /usr/bin/polipo PROCESS TYPES
SELinux defines process types (domains) for each process running on the system You can see the context of a process using the -Z option to ps Policy governs the access confined processes have to files. SELinux polipo_session policy is very flexible allowing users to setup their polipo_session processes in as secure a method as possible. The following process types are defined for polipo_session: polipo_session_t Note: semanage permissive -a polipo_session_t can be used to make the process type polipo_session_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. BOOLEANS
SELinux policy is customizable based on least access required. polipo_session policy is extremely flexible and has several booleans that allow you to manipulate the policy and run polipo_session with the tightest access possible. If you want to determine whether Polipo session daemon can bind tcp sockets to all unreserved ports, you must turn on the polipo_ses- sion_bind_all_unreserved_ports boolean. Disabled by default. setsebool -P polipo_session_bind_all_unreserved_ports 1 If you want to determine whether calling user domains can execute Polipo daemon in the polipo_session_t domain, you must turn on the polipo_session_users boolean. Disabled by default. setsebool -P polipo_session_users 1 If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlo- gin_nsswitch_use_ldap boolean. Disabled by default. setsebool -P authlogin_nsswitch_use_ldap 1 If you want to deny any process from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by default. setsebool -P deny_ptrace 1 If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default. setsebool -P domain_fd_use 1 If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by default. setsebool -P domain_kernel_load_modules 1 If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default. setsebool -P fips_mode 1 If you want to enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default. setsebool -P global_ssp 1 If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default. setsebool -P kerberos_enabled 1 If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default. setsebool -P nis_enabled 1 If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Disabled by default. setsebool -P nscd_use_shm 1 If you want to support ecryptfs home directories, you must turn on the use_ecryptfs_home_dirs boolean. Disabled by default. setsebool -P use_ecryptfs_home_dirs 1 If you want to support fusefs home directories, you must turn on the use_fusefs_home_dirs boolean. Disabled by default. setsebool -P use_fusefs_home_dirs 1 If you want to support NFS home directories, you must turn on the use_nfs_home_dirs boolean. Disabled by default. setsebool -P use_nfs_home_dirs 1 If you want to support SAMBA home directories, you must turn on the use_samba_home_dirs boolean. Disabled by default. setsebool -P use_samba_home_dirs 1 NSSWITCH DOMAIN
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server for the polipo_session_t, you must turn on the authlogin_nsswitch_use_ldap boolean. setsebool -P authlogin_nsswitch_use_ldap 1 If you want to allow confined applications to run with kerberos for the polipo_session_t, you must turn on the kerberos_enabled boolean. setsebool -P kerberos_enabled 1 MANAGED FILES
The SELinux process type polipo_session_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions. cifs_t ecryptfs_t /home/[^/]*/.Private(/.*)? /home/[^/]*/.ecryptfs(/.*)? fusefs_t /var/run/[^/]*/gvfs nfs_t polipo_cache_home_t /home/[^/]*/.polipo-cache(/.*)? COMMANDS
semanage fcontext can also be used to manipulate default file context mappings. semanage permissive can also be used to manipulate whether or not a process type is permissive. semanage module can also be used to enable/disable/install/remove policy modules. semanage boolean can also be used to manipulate the booleans system-config-selinux is a GUI tool available to customize SELinux policy settings.
