System Requirements

 Top  Previous  Next

You can use Dr.Web for Linux on a computer that meets the following requirements:

Component

Requirement

Platform

CPU with the Intel/AMD architecture and command system are supported: 32-bit (IA-32, x86); 64-bit (x86-64, x64, amd64).

Space on
hard disk

At least 512 MB of free disk space on a volume where the Dr.Web for Linux directories are located.

Operating
system

Linux for Intel x86/amd64 platform based on kernel ver. 2.6.37 or later, and using PAM and library glibc ver. 2.13 or later.

Tested Linux distributions are listed below.

For systems operating on 64-bit platforms, support of 32-bit applications must be enabled (probably, additional libraries must be installed for this, see below).

 

For the correct operation of SpIDer Gate, OS kernel must be built with inclusion of the following options:

•CONFIG_NETLINK_DIAG, CONFIG_INET_TCP_DIAG;

•CONFIG_NF_CONNTRACK_IPV4, CONFIG_NF_CONNTRACK_IPV6,
CONFIG_NF_CONNTRACK_EVENTS;

•CONFIG_NETFILTER_NETLINK_QUEUE,
CONFIG_NETFILTER_NETLINK_QUEUE_CT, CONFIG_NETFILTER_XT_MARK.

The set of required options from the specified list can depend on the used distribution kit of GNU/Linux.

Other

The following valid network connections:

•An Internet connection to download updates and for sending requests to the Dr.Web Cloud service (only if it is manually authorized by the user).

•When operating in central protection mode, connection to the server on the local network is enough; connection to the Internet is not required.

Dr.Web for Linux is incompatible with other anti-virus software programs. To avoid system errors and data loss that may occur when installing two anti-viruses on one computer, uninstall all other anti-virus programs from the computer before the Dr.Web for Linux installation.

The product was tested on the following Linux distributions:

Other Linux distributions that meet the above-mentioned requirements have not been tested for compatibility with Dr.Web for Linux but may be supported. If a compatibility issue occurs, contact technical support on the official website at https://support.drweb.com/request/.

Required additional components and packages

•For CentOS, Debian, Fedora, Red Hat Enterprise Linux, Ubuntu on the platform x86_64, a package that enables support for 32-bit applications is required (libc6-i386 or glibc.i686 depending on the OS).

•To enable Dr.Web for Linux operation in graphical mode and startup of the program for product installation and uninstallation in graphical mode, X Window System graphic shell and any window manager is required. Moreover, for correct operation of the indicator for Ubuntu Unity desktop environment, the additional library may be required (by default, the library named libappindicator1 is required).

•To start the product installer or uninstaller, designed for the command line, in graphical mode, a terminal emulator (such as xterm, xvt, etc.) is required.

•To enable privileges elevation during installation or uninstallation, one of the following utilities is required: su, sudo, gksu, gksudo, kdesu, kdesudo. For correct operation of the product, PAM must be used in the operating system.

For convenient work with Dr.Web for Linux in the command line, you can enable command auto-completion in the used command shell (if disabled).

 

If you encounter any problem with installation of additional packages and components, refer to manuals for the used distribution of the operating system.

Compatibility with components of operating systems

•By default, SpIDer Guard uses the fanotify system mechanism, while on those operating systems on which the fanotify is not implemented or is unavailable for other reasons, the component uses a special LKM module, which is supplied in pre-built form within the product. The product distribution has LKM modules for all GNU/Linux systems mentioned above. If required, you can build a kernel module independently from the distributed sorce codes for any OS that uses the kernel GNU/Linux of version 2.6.x and later.

Operation of SpIDer Guard via GNU/Linux (LKM module) is not supported for operating systems launched in the Xen hypervisor environment. An attempt to load the LKM module used by SpIDer Guard during the OS operation in the Xen environment can lead to a critical error of the kernel (so called “Kernel panic” error).

•SpIDer Gate may conflict with other with other firewalls installed in your system:

▫Conflict with Shorewall and SuseFirewall2 (for SUSE Linux Enterprise Server). In case of conflict with these firewalls, an error message of SpIDer Gate with a code x109 is displayed. A way to resolve this conflict is described in the Appendix "Known Errors".

▫Conflict with FirewallD (for Fedora, CentOS, Red Hat Enterprise Linux). In case of conflict with these firewall, the SpIDer Gate error message with a code x102 is displayed. A way to resolve this conflict is described in the Appendix "Known Errors".

•In case if the used OS includes the version of NetFilter less than 1.4.15, SpIDer Gate may operate incorrectly. This problem is related to the internal error of the NetFilter, and looks like as follows: after disabling SpIDer Gate, the network connections are broken and cannot be re-established. If you run into this problem, it is recommended to upgrade your OS to version that includes NetFilter 1.4.15 or above. How to resolve the problem, is described in the Appendix "Known Errors".

•Under normal operation, SpIDer Gate is compatible with all user applications that use network, including web browsers and mail clients. For the correct scanning of secured connections, it is necessary to add the certificate Dr.Web for Linux to the list of trusted certificates of those applications that use the secured connections (for example, web browsers and mail clients).

•After changing operation of SpIDer Gate (enabling of the previously disabled monitor, change of the scanning mode of secured connections), it is necessary to restart mail clients that use the IMAP protocol to receive email messages from the mail server.

Compatibility with Security Subsystems

By default, Dr.Web for Linux does not support SELinux. In addition, Dr.Web for Linux operates in reduced functionality mode in the GNU/Linux systems that use mandatory access models (for example, in systems supplied with the PARSEC mandatory access subsystem that appends different privilege levels to users and files).

If installation of Dr.Web for Linux is required for systems with SELinux, as well as for systems that use mandatory access models, it is necessary to execute additional settings of security subsystems so that Dr.Web for Linux operates in full functionality mode. For details, refer to the section Configuring Security Systems.
