Internet Security

Putting a computer on the Internet attaches it to millions of computers worldwide. In most cases, this is good, but it also opens your computer to remote attacks. The standard load of Linux or Windows is not very secure. Linux and Windows both tend to load every background program available, which opens up avenues of attack for hostile crackers. Turning off unneeded services is a good first step in Internet security. There are 65,535 ports on a UNIX machine. etc services is a list of most ports...

Name resolve order G

This option is used by the programs in the Samba suite to determine what naming services and in what order to resolve host names to IP addresses. The option takes a space separated string of different name resolution options. The options are lmhosts , host , wins and bcast . They cause names to be resolved as follows lmhosts Lookup an IP address in the Samba lmhosts file. host Do a standard host name to IP address resolution, using the system etc hosts, NIS, or DNS lookups. This method of name...

Samba as a Primary Domain Controller

As mentioned earlier, Samba can act as a PDC, but the full functions are not yet complete. The functions that work include The ability to act as a PDC for Windows NT 3.51 Service Pack 5 and 4.0 Service Pack 4 clients. This includes adding NT machines to the domain and authenticating users logging into the domain. The domain account can be viewed using the User Manager for Domains. Viewing resources on the Samba PDC via the Server Manager for Domains of the NT client. Windows 95 clients will...

Setting up an NIS Server on Linux

As mentioned above, NIS is a way of centrally managing usernames, passwords, and groups. It is used by all flavors of UNIX, including Linux. Since most Linux distributions don't come with NIS, the first thing that needs to be done is to download it. The current version can be downloaded at ftp ftp.keme . org pub linux utils net NIS. There are also binary RPM (Red Hat Package Manager) files available at http rpmfind.net linux RPM. Just search for nis-server and choose the one with the highest...

Mounting Windows Partitions with Linux

Fortunately, most Windows filesystems are supported by the Linux kernel. The mount command can be used to mount the partition For example, to mount the first partition on the first drive into the directory Now, changing the directory to mnt drivec (cd mnt drivec) will show the contents of the first partition, which would be the C drive in Windows. The mount command will usually detect the filesystem type on the partition. If not, use the -t option to specify the filesystem type. The supported...

Adding a Partition to the fstab

The file etc fstab is a text file that stores information on mountable drive systems. Adding an entry to this file will save having to enter long command lines every time you need to mount a partition. A typical fstab file would look something like this dev hda1 boot ext2 defaults 1 2 dev hda5 ext2 defaults 1 1 dev hda6 swap_upgrade swap defaults 0 0 mnt floppy mnt floppy supermount fs vfat,dev dev fd0 0 0 mnt cdrom mnt cdrom supermount fs iso9660,dev dev cdrom 0 This entry is broken down into...

Hard and Soft Mounts

The way NFS handles a lost connection is also important. There are hard and soft mounts. A soft mount will send an error to the programs that are accessing the NFS volume. Some programs can handle this, but most can't. A hard mount is a better option in most cases. It will suspend any programs that are accessing the NFS mount. It is added with the intr option, which will stop the program that is using the NFS mount. A hard intr is the best option in most cases. Once the optimum values are...

Streaming Video

Right now, the only complete video streaming package for Linux is Real Networks Real offers encoding tools (Real Producer and Real Presenter), streaming servers (Real Server), and players (Real Player). Real Producer Basic is available for Linux, Macintosh, and Windows. It takes live video or audio and converts it to Real Media format. This can then be streamed or downloaded and played with the Real Player. Real Producer Plus has additional features that allow better optimization...

Open Source Office Suites

Both KDE and Gnome have open source office suites under development. While neither is production-quality yet, they are already feature-rich and complete. Koffice is KDE's office suite. It comes with a word processor (Kword), spreadsheet (Kspread), presentation software (Kpresenter), a charting program (Kchart), a vector-based drawing tool (Killustrator), an imaging program (Kimage), a layer-based image creation program (KimageShop), and a database front-end (katabase). Koffice is still in...

Graphics Programs

The ability to use graphics is increasing in importance in business. All the office suites have a varying ability to manipulate graphics, but sometimes you need to do more. Stand-alone graphics programs come it two types photo editors and drawing programs. Photo editors allow you to manipulate photographs and images. These programs imitate many of the tools familiar to artists, including a paintbrush, pen, and airbrush. The most popular of these programs is Adobe Photoshop. The open source...

Web Server Compatibility

Let's start with the Web since it seems to be getting the most press lately. Web servers are relatively simple. They take text files (HTML files) and transfer them using the HTTP protocol. These text files tell the Internet browser how to display a page and where to download the graphics, sounds, programs, and other files needed to render the page. The three most popular Web servers are Apache, Internet Information Server (IIS), and Netscape, which together make up about 85 of the server...

Using MS Office Documents with Star Office

Star Office has very good support for MS Word and Excel files. Although it may lose some of the formatting, you can almost always get a readable file by opening a Word or Excel document in Star Office. On the other hand, PowerPoint is listed as one of the supported formats, but Star Office is not always able to open PowerPoint files. To open an Excel or Word file, simply choose File - Open from the menu. Word files will appear with the familiar Word icon and Excel files will have the Excel icon...

Tuning VMware

Many of the tuning parameters are mentioned in the installation and configuration discussions above. If the host or guest OS is sluggish, check the configuration parameters first. Make sure that there is enough memory and disk space allocated to each OS. If an OS doesn't have enough memory or disk space, reconfiguring your system may help. If there still isn't enough disk space or memory to run both operating systems properly, consider upgrading your PC. Other than that, installing the VMware...

System Error 1240

System error 1240 means that the client is refusing to talk to a non-encrypting server. Microsoft changed WinNT in service pack 3 to refuse to connect to servers that do not support SMB password encryption. There are two main solutions 1. enable SMB password encryption in Samba. See ENCRYPTION.txt in the Samba docs 2. disable this new behaviour in NT. See WinNT.txt in the Samba docs This is not a helpdesk The address samba-bugs samba.org is meant for reporting bugs or for obtaining help where...

SMB Clients and Servers Currently Available

There are a few SMB clients available today and a relatively large number of servers available from a range of vendors. The main clients are from Microsoft, and are included in Windows for WorkGroups 3.x, Windows 95, and Windows NT. They are most evident when you use the File Manager or the Windows 95 Explorer, as these allow you to connect to servers across the network. However they are also used when you open files using a UNC (universal naming convention). Some other clients that I am aware...

Smbclient Command Line Options

The general form of the smbclient command line is The servicename is the name of the Windows service you are attaching to. It is in the form of server share. The password is the password for the share or user logging into the service. This depends on whether Windows is using shared or user-level security. The options are covered below. -s smb.conf This points to the location of the smb.conf. Like the rest of the Samba suite, smbclient gets its settings from the smb.conf. -B ip address This...
