[SLUG] Project Management in Open Source

[Raphael Kraus]

G'day all,

I'm currently researching how open source projects are project managed. 
Texts, papers, and other resources that deal directly with this topic 
seem to be scant at best.


Can anyone provide any pointers? (Yes, this is for my Masters degree!) :)

All the best,

Raphael Kraus

Re: [SLUG] DODO

[Raphael Kraus]

I'd want steer clear of Dodo if you want adequate support. There is a
practical side on how they manage to keep bargain basement prices.

Personally, I have to recommend Internode. They tend to deliver on their
promises. FWIW, no ISP (or other organisation) is perfect IMHO.

All the best,

Raphael

Re: [SLUG] Prefered video card for Linux dual-head?

[Raphael Kraus]

G'day...

I remember days when nVidia setup was not so easy. In fact it was often 
down right frustrating with conflicting instructions. (From memory there 
was a nv as well as nvidia driver, and sometimes neither of which worked!)


The stellar efforts of the Linux developers figuring out nVidia cards, 
and distributions like Ubuntu have really taken the sting out of using 
the cards.


Dean Pittman makes a number of excellent points in this regard, and his 
advice should be well heeded.


Too bad if you need to use a kernel that can't run the pre-built driver. 
Also, just because the current models of nVidia work with current 
setups, doesn't mean you're not going to be disappointed in the near 
future.


There are /very/ pragmatic (not just idealistic) reasons for buying 
hardware products with open source drivers for use on open source platforms.


All the  best,

Raphael

I totally disagree, but I'm pragmatic not idealistic.

nvidia-settings let you setup 2 monitors, specify master monitor, and get it 
working in seconds, all in an easy GUI and IMHO setting up dual monitors IS a 
GUI task.

[SLUG] Removing ability to delete files from vsftpd (or other ftpd)

[Raphael Kraus]

G'day all,

I've got vsftpd setup so that only specific users can log-in. I have
permissions worked so that users can log-in, upload files but not read
or download them.

What I would like to do is remove the ability of users to delete files,
even though they can upload them.

I'm suspecting that maybe this isn't possible using vsftpd, but maybe
I'm just getting it wrong! (As vsftpd uses unix file permissions where
write permission on a directory means you can create or delete a file
irregardless of the permissions on the file itself.)

TIA and all the best,

Personally I find mysqldump to be great. How humanly readable it is does
depend on how well the database has been designed. (Having said that, if
the implementation is confusing, it doesn't matter how well you try to
present the raw data.) The proviso here is that it would be helpful if
you understood at least some SQL, as after all you are wanting to look
at table structure. (It's really not that complicated though, if you
take a look at it.)

You can get a dump of the database from the command line, or via a web
interface if you are using phpmyadmin.

HTH - all the best,

Raphael

[SLUG] KVM/QEMU behaviour under (Debian or) Ubuntu Desktop AMD64

[Raphael Kraus]

G'day all,

Working with the above, I'm finding some problems. (AMD2 socket.)

First, I find excessive:

printk: 249 messages supressed.
rtc: lost some interrupts at 1024Hz.

messages in /var/log/messages.

This happens for both QEMU and KVM. However, in KVM I can specify 
-no-rtc. (QEMU has the KQEMU enhancement enabled.)


The virtual machines also seem to have periods of slow-downs and 
no-responsiveness under KVM. I'm not sure if this is the case under QEMU 
(I'm trying it now).


I also find that I can install Ubuntu  under QEMU, but I'm unable to do 
so under KVM. I can install Ubuntu 6 under QEMU, and it will run then 
under KVM however if I upgrade to Feisty it will fall over at bootup 
under KVM  but not QEMU.


The hpet emulation arguments are set to yes (as recommended by the KVM 
webpage) by the Ubuntu defaults for KVM. I think the problem must lie 
with QEMU somewhere, and is carried by KVM.


I'm wanting to keep the system fairly standard so may need to submit a 
bug report to Ubuntu/Debian.


Have others experienced this behaviour? I'm very keen to hear from you.

All the best,

Raphael

Re: [SLUG] removing duplicate files

[Raphael Kraus]

G'day...




In that circumstance, there's a way to do it with just ls:

spindle:~/tmp polleyj$ ls -lR */somefile somefile
-rw-r--r--   1 polleyj  polleyj  0 Jul  4 21:20 hello/somefile
-rw-r--r--   1 polleyj  polleyj  0 Jul  4 21:20 somefile

it doesn't scale though; for the general case, find is more useful, as
you've said.



Whilst we're being pedantic...

$ find . -type d -name ""

Yes, you're right find is very useful... ;)

All the best!

I'm trying to transfer a large file from computer A to computer B 
using a null modem cable. The file is a compressed file which, when 
transferred, will allow me to install on computer B the distribution 
called Delilinux. I have no other way of getting the file onto 
computer B than via the cable.


Preparatory to such a transfer, I've run a couple of installation 
floppy disks on computer B. They're supposed, among other things, to 
install pppd on computer B. In order to make it easy to transfer the 
file using pppd, you're prompted to do certain things after the 
installation on computer B of pppd.


One is obviously to run pppd on computer A. However, computer B tells 
you, in effect, that computer A must have the address 192.168.0.1. 
I've run on computer A the command I'm told to, but no connection 
between the two computers is created.


Computer A is behind a modem/router and already has the address 10.1.1.1.

Is that likely to be the reason why no connection is created?

If so, is there a way to give 10.1.1.1 the alias of 192.168.0.2?

If not, it seems that computer B has on it Telnet. Can I use that to 
transfer the file instead?


Thanks for reading this,

Re: [SLUG] Postfix question

[Raphael Kraus]

Howard,

I think you have the wrong idea about relayhost. The relayhost parameter 
in main.cf of postfix is for you to specify an external SMTP server to 
send through (aka a smarthost).


Don't specify an internal host for this (unless you insist on sending 
through that host). Usually the parameter would be set to your ISP's 
SMTP server, or the SMTP server specified by your SPF records.


What you want to do is set up the relay_domains and transport parameters:

Something like:

relay_domains = yourdomainname.com.au
transport_maps = hash:/etc/postfix/transport

in main.cf and put in /etc/postfix/transport

yourdomainname.com.au smtp:[192.168.0.143]

Again, remember to run postmap /etc/postfix/transport

Obviously you'll also have to adjust domain names and IP addresses as 
needed.


http://www.postfix.org/ has wonderful documentation available. There are 
also a lot of examples that you can learn from.


All the best.

Raphael

Howard Lowndes wrote:
I have a Linux/Postfix server that accepts email from the Internet,

The Postfix checks are all being done by LDAP so I am able to see what 
is happening on the Linux/Postfix server.


Postfix has the relayhost parameter set in main.cf to point to the 
Linux/Domino server so that emails are correctly forwarded on.


I can see the Linux/Postfix server doing all the checks that I have 
specified in main.cf.  These include:

smtpd_client_restrictions
smtpd_helo_restrictions
smtpd_sender_restrictions
smtpd_recipient_restrictions

However, the smtpd_recipient_restrictions appear to be failing safe 
with a default DUNNO result rather than a default REJECT result.  The 
same checks, when not used in conjunction with a relayhost setting 
appear to default fail as REJECT rather than DUNNO.


Am I right in assuming that the use of the relayhost parameter is 
causing this change in default behaviour, and how is the best way to 
fix it?

Re: [SLUG] Hotmail blocking emails

[Raphael Kraus]

G'day Stu,


We just got 40 bounces (550s) from hotmail.com. Nothing's changed
here.  We've checked all the usual suspects (dns/mta) but mail is
going everywhere else OK. As usual the bounce-reply is non-specific
and points to a general, vague support page.

Q: If you start getting bounces from a particular mob, what MTA/spam
list checkers to you use to see if you've broken some rule?


Does your outgoing mail server have a reverse DNS PTR record set for its 
IP address?


(Note that it doesn't need to match your domain, just so long as its a 
hostname that will revert back to the IP.)



You can always check the IP address of your mail servers from 
http://www.dnsstuff.com/ - There's a broad ranging SPAM database check 
there.


All the best!

RE: [SLUG] Problems backing up a server to SMBFS

Just wanted to thank Marty Richards, Tuxta, Penedo, Sonia Hamilton and
Michael Fox for assisting me on this one a short while ago.

It turns out that using cifs rather than smbfs resolves this.

I have to say I'm surprised at this, as it is Samba 3 and also that cifs

wget -nc will stop it downloading an existing file in the same
directory, but to do what you're suggesting - if you then move or delete
said file you would probably need to do something clever like output to
a logfile (-o  initially, then -a  to append to the same
file), then pipe that file back in using an 'exclude' to ignore those
files. You'd probably need to wrap that in a script to get it to work
correctly though.

HTH,
Craig

wget -nc will stop it downloading an existing file in the same
directory, but to do what you're suggesting - if you then move or delete
said file you would probably need to do something clever like output to
a logfile (-o  initially, then -a  to append to the same
file), then pipe that file back in using an 'exclude' to ignore those
files. You'd probably need to wrap that in a script to get it to work
correctly though.

[SLUG] wget remembering previous downloads

[Raphael Kraus]

G'day all...
 
I'm 
doing some man'ning to no avail here...
 
Is 
there a way to have wget (downloading via ftp) to remember what it has 
successfully downloaded, and not to download the same file again - even if the 
file is deleted from disk?
 
If 
not, has anyone else had to face this problem before?

[SLUG] qmail relay queue

RE: [SLUG] Poor Gb network performance

[Raphael Kraus]

> Also, I've seen problems with the Realteks in 2.6.9 kernels, that
seemed to go away with later 2.6 kernels (around 2.6.13, from memory).
> Given the debian box is 2.6.8, that might be an issue, so you might

That may be a good point, however as the machine is off-site, rather
critical, uses some compiled software and eth0 is less important (i.e.
it's our internal network - I'm more worried about large backups not
taking forever to transfer), I'm not too keen to upgrade the kernel just
at the moment  :^/

I'll discuss this with my colleage and we'll see if we can organise to
give it a crack...

RE: [SLUG] Poor Gb network performance

[Raphael Kraus]

Hrmm... Have thought about the cables - may be worth a shot as the
cabinet is so tight, but it is a long shot...

Aah... A Nvidia "softnic" is on-board both of the machines, and a PCI
Realtek. On Debian the Nvidia is eth0 and Realtek eth1 and vice versa on
the Ubuntu.

Not sure on any control utilities - been a while since I've examined nic
drivers (or any other drivers for that matter). I'll check it out.
(Refernces welcome :)

So you've got an Nvidia "softnic" (rather like a softmodem, so kind of
icky if you're looking for performance) and a Realtek, which are not
widely known for their performance. I'm not sure that explains the full
extent of your performance problems, but it's a start.

Are there any control utilities or module parameters for forcedeth?
Perhaps you could switch it between performance modes (to favour CPU or
throughput, pick your poison).

Long shot: Make sure you have a good cable.

[SLUG] Poor Gb network performance

[Raphael Kraus]

G'day all,

We've got Ubuntu and Debian machines connected to our gigabyte networks.

Ubuntu kernel: 2.6.15-26-amd64-server
Debian kernel: 2.6.8.3-k7-smp

(Processors are AMD Athlon64 dual-cores.)

Both machines don't seem to be getting through data throughput across
the network. We're getting 10 ~ 12 MB/s (usu. ~11MB/s).

By my calculations we should be getting around ten times this.  Netgear
switches are being used.

Is anyone aware of any issues that would be causing this?

[SLUG] FTP directory synchronisation

[Raphael Kraus]

G'day all,

I'm wanting to perform FTP synchronisation (similar to rsync) - i.e. a 
local and remote directory are made up to date at a set schedule.


Where two files of the same name exist on both remote and local hosts, 
the older one is overwritten with the newer. Subdirectories are searched 
recursively.


Are there any suggestions on how this can be / should be done?

TIA!

[SLUG] Video conferencing

[Raphael Kraus]

G'day...

I'd like to video conference with my father (Townsville, QLD) and my
brother (Brooklyn, NY, USA). They've both got Mac's (OS X) and surely
have iChat.

I run a Debian box, and a webcam (Logitech Orbit) that works.

Can anyone offer any hints, tips or advice on what software I should use
to do this. Ideally, it'd be great if we each had two to three small
windows (one each of the other two parties and optional third of
ourselves for our own vanity)...

Don't know if this is possible and if gnome-meeting is capable.

All nudges in the right direction appreciated :)

Thanks

[SLUG] MondoRescue via NFS

[Raphael Kraus]

G'day...
 
Has anyone had any experience using MondoRescue over NFS?
 
I'm getting very frustrated with the documentation, as it is sparse in
the spots I'm needing more information. (E.g. "Press enter a few times
and it'll work" - no it doesn't and there's no further descriptions
argh!) 
 
Anyway, I've performed a back-up to an NFS server. How do I restore from
NFS? I've got another box here with which I want to test a bare metal
restore on.

[SLUG] ctrl-alt-left ctrl-alt-right under VNC (OT?)

[Raphael Kraus]

G'day,

(Warning: some readers may consider this mail off-topic for the list!)

I'm sure I used to be able to do this (although I'm wondering now).  
Using gnome desktop, you can ctrl-alt-left and right between desktops. 
However, viewing the desktop via VNC this isn't possible (or at least 
not conveniently possible). (VNC client is running under WinXP.)


Does anyone know a work-around?

Thanks

The words themselves were said with a smile and tounge-in-cheek. :)

I think I did have something constructive to say - having a sense of 
humour and being able to relate to a sense of humour is an important 
part of our profession that is often lacking. (It challenges me when I 
get the grumps with some upstart on a mailing list!) ;) :)


(As an exercise, try smiling and listening to your boss - hard as it may 
be sometimes doing so will often mean he'll listen to you that time when 
you think you need another Linux server.)


Anyway the point is that Paul J Fenwick and Jacinta Richardson make 
/significant/ /unpaid/ and /voluntary/ contributions to the Open Source 
community. (Really, you should follow their movements if you don't 
believe me!)


Paul's presentation was, as per usual, excellent. AFAIR, it is also a 
shorter version of the talk he is giving at the Open Source conference 
later this year.


It's a pity you weren't there to see it.

[SLUG] LVM and software RAID

[Raphael Kraus]

G'day,

We're trying to set-up a host with software RAID (mirroring) and LVM at
work (for a backup server).

Just trying to install Debian with RAID partitions is proving painful.

Anyone done this before? Any recommendations, tips, suggested methods?

I'm thinking I should install to one drive putting a plain boot
partition and then a LVM on it, leaving the second alone. Once install
is complete create the RAID with the second drive marked as failed. (I
can remember doing this a while back, but I think RAID has changed on
Linux now.)

Sorry if I'm answering my own questions here. I've struggled with
Debian's installer and seen my colleague spend longer on it, whilst
being head down in programming. Consciousness seems to have clicked a
bit more since relaxing.

Look forward to seeing you all again on Friday week.
