The printer is a Lexmark c532dn and I'm runninf Gutsy G on a laptop.
I'd like to connent it to a network, but the installation programs I've

Someone suggested CUPS.
Has anyone any experience with this model?
Looking at the specs it is a fairly standard PostScript
printer with a ethernet port.
ATTACH THE PRINTER, GIVE IT A NAME AND ADDRESS
The first thing to do is to plug it into the ethernet.
Your DHCP server will give it an address and print its
ethernet MAC address in the log file.
DHCPDISCOVER from 00:12:34:12:34:56 via eth0
Since it's useful for printers to have a fixed name
enter one in /etc/dhcpd.conf
host lexmark-c523dn-1 {
hardware ethernet 00:12:34:12:34:56;
option host-name lexmark-c523dn-1;
option domain-name printers.example.edu.au;
ddns-hostname lexmark-c523dn-1;
ddns-domainname printers.example.edu.au;
}
If you don't run Dynamic DNS then do it the old fashioned
way by giving it a fixed IP address in DHCP
host lexmark-c523dn-1 {
hardware ethernet 00:12:34:12:34:56;
option host-name lexmark-c523dn-1;
option domain-name printers.example.edu.au;
fixed-address 1.2.3.4;
}
and manually updating your DNS zones
lexmark-c523dn-1.printers.example.edu.au. IN A 1.2.3.4
in-addr.arpa.4.3.2.1. IN PTR lexmark-c523dn-1.printers.example.edu.au.
You might want to add
option ntp-servers 1.2.3.1;
option log-servers 1.2.3.2;
as this will put the right time on the printer and send any messages
to your site's syslog server so you can see what happened when things
go wrong.
Now restart the printer and it will pick up its new address
and name.
Although this is a lot of messing about, avoiding configuring the
IP address onto the printer manually is well worth the hassle.
Using DHCP as widely as possible makes network changes later
on much more simple. Using DHCP with DDNS makes life very,
very simple.
CONFIGURE PRINT QUEUE
Configure the printer into CUPS. There's some nice GUIs for
this. I really recommend using the GUI interface, then
checking the configuration file afterwards. You see
something like this in /etc/cups/printers.conf
DefaultPrinter lexmark-c523dn-1
Info Lexmark C532dn colour laser printer
Location Room 101
DeviceURI ipp://lexmark-c523dn-1.printers.example.edu.au/ipp/port1
...
/Printer
I really recommend using the GUI interface, then checking the
configuration file afterwards.
If the printer isn't in the GUI then select the Generic Postscript
option and say you have a .PPD file. A PPD is a printer description
file and it tells CUPS and other programs about the printer's
capabilities.
Look on linuxprinting.org for a PPD file. If there isn't one then
look on the CD that came with the printer and look for a .PPD file
there. You may need to use cabextract or unshield to explode
installer data files. Some Windows PostScript drivers use PPD
files, so there will be one somewhere.
Linux has excellent support for PostScript printers. You'll be
very pleased with the results.
PRINTERS FOR SMALL BUSINESS
If you have an office, rather than just one computer, then set
up a VLAN just for printers, say VLAN 10 with addresses 10.10.10.*/24.
Put an interface of the CUPS server on this VLAN and another interface
of that server on the routed network of your office. Now users
can only see the CUPS queues -- this is a good thing.
The CUPS server will advertise all the printers it knows of, and
Linux and MacOS X users need no configuration to use the printer.
You can gateway CUPS into Samba. Do this at the CUPS server.
The Samba server can contain the Windows printer drivers too,
so visitors with Windows machines can easily use your printer
too.
The printers cannot be contacted directly from the office network
or from the Internet. This means you don't need to worry if
the printer software has a vulnerability (and a lot of then do).
The CUPS server is acting as an application-specific firewall
for the printers.

[SLUG] ClamAV user interface on Ubuntu 7.10 - how to access GUI?
Hi. I am not familiar with Ubuntu, but a friend recently upgraded from Ubuntu 6 to 7 and I helped him after the upgrade. (He got a new system with Ubuntu 7 on it, so it was a fresh install.) One of the things I did was run apt-get install clamav to install anti-virus on it, per his request, I want to have anti-virus and I used to have ClamAV. Now he says, In my previous computer I was able to check that the security was up to date by going into Applications Clamav but I do not see any means to do that on this computer. How do I get ClamAV to show up under his applications, please? Should I have installed it a different way?

[SLUG] Ubuntu 7.10 looses printer settings
Hi all, Sorry to bother you all again. I am using Ubuntu 7.10 and using an HP 5150 to print onto. The problem is, is that Ubuntu 7.10 looses the printer drivers as when you want to print something nothing happens until you remove the old printer driver and then reinstall the printer driver. Is there a way to fix the above or is there something that I am doing wrong as this did not happen in the previous release of Ubuntu.

Re: [SLUG] ClamAV user interface on Ubuntu 7.10 - how to access GUI?
G'day Aleksey, I've never used ClamAV before, but I did apt-cache search clamav to get a list of clamav-related packages and noticed that there's a package called avscan which provides a GTK frontend for ClamAV. So you probably want to do sudo apt-get install avscan. Another one you might want to try is clamtk. - James Foster On Thu, Feb 21, 2008 at 9:35 PM, Aleksey Tsalolikhin [EMAIL PROTECTED] wrote: Hi.

A normal Linux system does not need anti-virus software. The main reason to run such software is to clean Windows viruses before they can get to Windows machines (e.g. on an e-mail server).

Going for about $450 at JB Hifi and less on eBay. I picked one up about a month ago, while they were still pretty much exclusive to Myer. The installed operating system is Xandros with icewm and a custom desktop interface. I can't comment on it too much because getting what I wanted out of it seemed too much effort so I installed xubuntu over the top of it in short order. But my one other (non-technical) friend who has one absolutely loves the OS. It's small and light and fairly awesome. The keyboard feels slightly cramped (the right shift key irritates me no end). The screen resolution is 1024x600. Again, a little getting used to (the wiki over at eeeuser.com has a lot of tips for small themes and trimming a lot of vertical space from firefox and the like), but I personally think it's pretty good for things like web browsing. For the price, I think it's a great machine. If anybody wants to have a poke at it, I'm planning on turning up at the next SLUG meeting. -- Pete -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Re: [SLUG] Asus Eee 4G 7 Micro Laptop
There were dozens at LCA last month - geek envy abounded. They seem very solid.

It seems this form factor (and capability) is neatly filling the gap between regular notebooks and PDAs that tablets and UMPC have failed to fill.
