This is re canon printer Bjc 250

Every time I want it to print using the canon printer bjc 250 it sends out a mostly blank piece of paper with some unreadable symbols at the topand then the second sheet it will print as directed I have shut my scanner off and it still does the same thing Thanks for your help in advance

Bessie, I'd say at first glance that the init string for the printer is not quite right, but whatever it does between pages is, and needs to be applied. Unfortunately without knowing which Linux based print setup you're using, we can't go farther with that.

There's decent stuff out there for actually just getting the drivers in (The Printing Howto at https://www.linuxprinting.org/howto/how.html being canonical) - but they are a tiny bit technical, mentioning buzzwords and kernel parameters and so on. She seems to have gotten that far, anyway. If you have a lively tale of your adventures in printer setup and success, that you think would educate your fellow readers, especially the newbies among us, then we'd love to see your artIcle. -- Heather

Sendmail + Courier IMAP

Hi! Good day.

I've been looking for a good documentation on configuring Sendmail + Courier IMAP (with MailDir) but I can't find one. My server's specs:


Mandrake 8.2
Sendmail 8.12
Procmail 3.22

Currently, I'm using the IMAP and POP server distributed with Mandrake. Im using Postfix as my MTA before, but when I needed to use MailScanner (https://www.mailscanner.info) I have no choice but to use Sendmail. I want to switch to Courier IMAP and make use of their MailDir feature and MySQL auth, but I can't find a good tutorial or howto. I believe you can help me with this one.

Thanks and more power

Postfix ?

Hi,

I have installed the Mandrake-Linux 8 and Postfix , all the thing run smoothly on Linux machine but whenever I try to get Email from my windows computer (Outlook Express) . I get ther error message

Your server has unexpectedly terminated the connection. Possible causes for
this include server problems, network problems, or a long period of
inactivity. Account: 'Root', Server: '192.0.0.2', Protocol: POP3, Port: 110,
Secure(SSL): No, Error Number: 0x800CCC0F

The NIC both of PC is working and also ping to eachother.

Please help me in this regard how to collect email from my Linux machine in OutLook Express (win98 ) .

Thanks & best regards.
Shahid Ahmad.

Ethernet errors, possible conflict?

I have been searching everywhere for a possible cause to this little problem. I have two LNE100tx Ethernet adapters in a Redhat Linux 7.1 machine with kernel version 2.4.9-34smp. Eth0 is hooked to a 100tx switch and Eth1 to a Toshiba cable modem, both using cat5e cable with very short runs. I use an iptables based firewall rule set to allow for ip-masquerading. The inside interface works perfectly, and so far as I've seen the outside interface actually works perfectly in spite of the fact that ifconfig shows that I have 0 tx packets on that interface and tons of errors. My real question is if these are true readings how can I still ping this machine and receive responses without it transmitting packets to the cable modem? I have included some relevant output from ifconfig, iptables -L as I'm not sure that it's not a conflict in my rule set, and ping output from another location. Any information on this problem (even if it's just that the output of ifconfig is wrong) would be greatly appreciated.

Ifconfig output:

See attached bradbury.ifconfig.txt

iptables -L output:

See attached bradbury.iptables.txt

ping output:

See attached bradbury.ping.txt

Thanks in advance,
Matt Bradbury

It used to be that you could be sure not to be able to ping from behind IP masquerades. There's some sign this has changed in 2.4. If anyone knows the gory details, let us know how you do it. -- Heather

Step by step multilink ppp dual modems?

I have no problems finding references that multilink ppp dual modems are possible in linux but for the life of me I can't find a step by step guide how to set this up. I am a newbe using Mandrake 8.2 and would really appreciate info on how to actually set my computer up for multilink 56k modems. My ISP does provide this service.

You will most likely need to re-configure and compile your kernel - you will need to install the source pkg from your Mandrake installation CD's if it's not already installed. I don't believe that that most distro supplied kernels are configured for that. From the kernel confg help:

Re: article idea - making the minidistro

How to make a minimal Linux system with uClibc and Busybox is described in an article on my home page "Getting Linux into Small Machines". See https://www.xs4all.nl/~lennartb/linux.html

Not a complete mini distro, but maybe a good starting point.

One of our Answer Gang members is also plotting to write a bit of an article about the LNX-BBC rescue minidisc. The rest of us are encouraging him, so maybe you'll see something on that one at some point too -- Heather

Nigeria scam

A followup to the continuing Nigeria business scam spams we receive every day (which are lampooned on the Back Page this issue as in most other issues): 15 Nigerians were arrested in South Africa on money scam charges.

PS. The Gazette mailbox is still getting 10-20 of those critters a day, often including several copies of the same e-mail.

Sweet...

As a long time self-taught user of Linux/Unix/Ultrix (and several other flavours), I've become addicted to such handy tools as vi, grep, sed, awk, ctags, and the bazillion other little utilities that can be so artisticly chained together to produce the desired results. I've stumbled across your LG archives, and all I can say is "WOAH!" I'm going to have to find myself a text-to-speech translator so I can read/listen-to all of this good stuff whilst at work, because there's just so much in here. Thanks for such a fabulous (and fun!) resource...

Glad you're enjoying it, Tim. Given that you do have this broad range of experience, you might want to give a thought to joining The Answer Gang; as far as I'm concerned, it's the most fun part of LG. You don't have to have all the answers... as long as you have a few, you can contribute. Take a look at:

Mxxxxx@xxxxxxxx.com is not on any of our mailing lists.

The unusual Subject: line and From: line suggest you received a message from a Klez worm/virus. Klez operates by choosing a To: address and a From: address randomly from the user's Microsoft Outlook address book. In other words, it comes from someplace completely different than where it claims to have come from. If you know anybody who uses Outlook and has both your address and LG's in their addressbook, you can warn them. Or if you have the original message, you can tell from its Received: headers which domain it came from. If you want to send me the headers, I can show you how to verify whether it's Klez and what the originating domain is.

Usually Klez messages come with a binary attachment, but sometimes the program goofs and sends only a one-liner. Of course, you don't ever want to run -- or let your computer automatically run -- a binary attachment from somebody you don't know, because that's how viruses and worms spread. Klez in particular also tries to disguise the attachment so it looks like a different type than it is. For instance, it can disguise an executable program as a sound file, which tricks certain versions of Windows into executing it.

mailbag question

In the 'mailbag' of the 'linux gazette' there was someone (without e-mailadress) who had a question about running a Linux server behind a w2k ICS server (Linux terminal services server can't connect to internet via network) Now I was wondering, should whoever reads this and know a solution or more details then he/she does e-mail to this adress so it'll come in the next mailbag? Is that how this works? If so, I'd like to reply (very much)

I'm not entirely sure of that... but they're the same crew, (of people mangling the replies) so if you know something, I'd say shoot.

Cheers, -- jra

If you have an answer to someone who requested anonymity, you can always send your message to tag@lists.linuxgazette.net with a subject indicating which issue and question it's for, and we'll publish it in 2 Cent Tips or The Answer Gang if appropriate. Probably we'll forward it, but it's possible we'd just let the reader find it in the next issue. -- Heather
