I would consider an external backup that's cheap and not really limited in
terms of space - glacier or something similar. Drop a monthly archive there
without --delete and even if some garbage accumulates, it's not a big deal.

It all really depends on the amount of data in question, if it's not
insanely huge, you can simply buy some cheap drives and do the same thing.
Tiered backups aren't anything new, it is best practice to have a set of
fresh hot backups, like your dailies, a weekly or biweekly warm archive in
case you need to pull out something older, and a cold archive that's
essentially a big dump of ancient stuff on very cheap and very slow medium,
used for emergencies.

For this, I would run a seperate infrequent backup without --delete, and
dump it on the cold storage, just in case.

Another option, if you want to save space, would be to drop rsync and
switch to something like backy2 or it's alternatives.

You don't, that's the whole point of venv - you have a separate set of
modules in each environment, specific to it's version.

There's the site-packages argument of course, but it's far from being
best-practice.

Re: Advice on lightweight laptops for Linux (of course)

[Dan Yasny]

The point here is that they sacrifice a lot of the think* series sturdiness
for the lack of weight and thickness. And you can't upgrade the thing, it's
all a single block you can't take apart. There's also a problem with later
kernels getting mces and panics on overheating because of a bug in the way
the kernel manages pstates - dynamic turbo  mode or whatever intel call it.
The only way around I found is to disable pstates altogether.

Re: Advice on lightweight laptops for Linux (of course)

[Dan Yasny]

I've been carrying an X1 around for a couple of years now. The battery life
is great, Fedora support is great, weight and convenience is quite good,
except the keyboard is a bit on the weird side when it comes to the
function keys and the missing insert key, but I've learned to live with
that.

The downside however is the reliability. In this time I've had the screen
replaced, the keyboard replaced and the motherboard/cpu/ram/etc (it's all a
single block) replaced. Each time it takes a week at the lab (I don't have
the onsite warranty, and I am in Canada, so YMMV). So if you intend to use
it somewhere where warranty isn't available, or if you intend to use it
longer than the warranty period - stay away. It's expensive enough to be
expected to last, but it's quite flimsy.

Re: LPI Certification

[Dan Yasny]

The problem with trivia based certification is that it's so easy to get
without actually knowing anything. Download braindumps, go over them a few
dozen times, and you can pass any exam that is based on standard questions.
In Europe and the US, high-end IT shops know this full well, and they would
only look at certifications that are more implementational than trivial, or
at actual experience, especially because there's a huge, dirt-cheap
workforce out there with MCSEs and CCNAs, and no real world experience.
None of those guys would pass an RHCE exam, because there, you'd have to
actually sit down in front of a machine and do real actions, instead of
memorizing braindumps and redumping them.

So if the goal is to find a job in high-end IT companies, banks and so on,
you have to keep in mind that a trivia based cert with no experience to
back it up will take you nowhere.

 My guess is that Microsoft and Cisco certifications will be worth more as
 it shows that you know how to play well with others and (almost) no one
 has a 100% linux shop.

mark your email as offtopic, you know, like everyone in every other LUG

As soon as a list(/community/forum/etc) turns into an offtopic promoting

Nothing is vague here. This is off topic, your stories aren't interesting,
aren't funny and would not belong in a LUG, even if they were.

 For the record, I tolerate things that are of much lower SNR here like job
 offers for which hardly anyone here is qualified or is willing to apply,
 and this is on topic here despite (or even due to) being fiction.


Job offers at least, are related to the tech that this list is there to
discuss. I'm not saying everything has to be about technology, but what you

 Or if it turns out that you were born in Canada, or have a relative that
 was born in Canada, you are a Canadian citizen.

 I was born in Canada, my parents were dual US/Canadian citizens. I moved
 to the US when I was 5, and never went back, so I lost my citizenship.

 About two years ago, the law was changed, and I am now a Canadian citizen,
 so is my wife, my children (who have never been to Canada), and their
 spouses and their children*.

 I think it goes farther than that.

 In order to claim your free citizenship, you fill out a form and send them
 $75, which gets you a citizen's ID card (similar to a tehudat zehut). Once
 you have one of those you can apply for a passport.

 Since the citizenship was bestowed upon you, and not requested it does not
 affect your other (e.g. US or Israeli citizenship) you may have, nor does
 it incur any tax liability.

 * My oldest son is the only one who is married and it turns out his wife's
 father was born in Canada, so he would also be a citizen, and so would his

Re: Computer recommendation for Linux server.

[Dima (Dan) Yasny]

any brandname machine with the right specs will do. a word of warning
though - don't hope to scale the specs, purchase the max set of
hardware you'll need right away - upgrades can be more expensive than
the machine itself.

If you expect to need more than a single server, maybe a beefy machine
that can carry multiple VMs would be preferable.

 I searched the archives and only found a few answers to the

 The server needs a good RAID 5 card and, if possible, a dual

 The budget is up to 10,000 shekels.
 The computer should be able to serve  80 - 100 client computers.

Re: mail issues questions

[Dima (Dan) Yasny]

I've had problems sending to yahoo, until I set up DKIM. Never tried
hotmail, though none of the mailbox holders ever complained, so I guess it's
fine there.

Can you post a smtp transcript, done manually?

2011/2/28 Hetz Ben Hamo het...@gmail.com

 Hi,

 There used to be a time that in order to setup a mail server, all you had
 to do is the mail server itself, MX records, PTR and you're done.
 These days you'll need to also have SPF and DKIM.

 I did all the things for a mail server for my business, tested few emails
 to gmail, walla and other places, and I got it correctly without going to
 spam.
 Yahoo and Hotmail is another story: Yahoo moves the mail I send to SPAM
 while in Hotmail the email simply doesn't show up anywhere.

 I looked at the logs (I'm using postfix) and I don't see any error message
 at all. Here's an example:

 Feb 28 02:02:03 mail postfix/smtp[5758]: 256081900B2: to=
 heuni...@yahoo.com, relay=127.0.0.1[127.0.0.1]:10024, delay=1.6,
 delays=0.04/0.01/0.01/1.6, dsn=2.0.0, status=sent (250 2.0.0 Ok,
 id=08689-09, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as
 B79C11900C2)
 Feb 28 02:02:03 mail postfix/smtpd[5764]: disconnect from
 mail.hetzbiz.info[127.0.0.1]
 Feb 28 02:02:03 mail postfix/qmgr[12019]: 256081900B2: removed
 Feb 28 02:02:03 mail postfix/qmgr[12019]: B79C11900C2: from=
 h...@hetzbiz.info, size=1508, nrcpt=1 (queue active)
 Feb 28 02:02:05 mail postfix/smtp[5765]: B79C11900C2: to=
 heuni...@yahoo.com, relay=g.mx.mail.yahoo.com[98.137.54.238]:25,
 delay=2.2, delays=0.03/0.01/0.75/1.4, dsn=2.0.0, status=sent (250 ok dirdel)

 Same for hotmail, Code 250 (which means it send OK).

 I tried to contact Hotmail support, only to find some that I need to
 register to their Sender ID (did it, successfully) and the SPAM protection
 program (which I failed since I don't have any opt out - go tell them that
 all the customers in this business are paying, and if someone leaves, he
 won't get any service/emails, I already replied that to them).

 Any tips what can be done about these 2? (hotmail and yahoo)

 Thanks,
 Hetz

Re: mail issues questions

[Dima (Dan) Yasny]

DKIM is a method of publishing a public key in a txt DNS record, with which
the subject line of every email sent, is signed. When yahoo MTA's receive an
email, they don't just check the PTR record, they also check the subject
line signature, with the public key available in the DNS records. If the
signatures match - email goes through, otherwise it's dropped.

And as for SPF: http://en.wikipedia.org/wiki/Sender_Policy_Framework

 Hi,

 I'm getting some really weird error, even though the network on the machine
 works well.
 When I'm doing: service network restart or ifup eth0, I'm getting a
 message: RTNETLINK answers: Network is unreachable.

 It is reachable. route's output is perfectly ok, the machine can access the
 net and I can access it from outside. DNS works, ping works etc..

 Looking at /var/log/messages, all I see is:

 Feb 14 13:23:00 testing23 kernel: eth0: intr type 2, mode 0, 1 vectors
 allocated
 Feb 14 13:23:00 testing23  kernel: eth0: NIC Link is Up 1 Mbps

 Here is my ifcfg-eth0 (it's a virtual machine, so the check_link stuff is
 what vmware added)

 DEVICE=eth0
 ONBOOT=yes
 USERCTL=no
 BOOTPROTO=none
 NETMASK=255.255.255.224
 IPADDR=82.XXX.XXX.203
 PEERDNS=no

 check_link_down() {
 return 1;
 }
 HWADDR=00:50:56:a3:00:18
 GATEWAY=82.XXX.XXX.193
 TYPE=Ethernet

 Any suggestions?

 Thanks,
 Hetz

Re: weird network issue

[Dima (Dan) Yasny]

If you remove the check link parts, do you keep seeing the issue? Would also
be nice to try with a different NIC type (e1000 or virtio)

 Hello Hetz,
 1. Does the virtual machine have additional network cards (eth1, eth2,
 etc.)?  If yes, you may be accessing the network via those cards rather
 than via eth0. (Statement about proper routing withstanding.)


 Nada. eth0, lo - nothing more.


 2. Which Linux distribution is running in the virtual machine?


 Centos 5.5 64 bit + updates.



 Google search (rtnetlink answers network is unreachable) yielded the
 following possibilities:
 - Misconfigured IP address in firewall script.


 No new IP addresses were added. Default firewall configuration.


 - Network card does not exist (as far as the virtual machine is
 concerned).


 exists, I'm ssh'ed to this machine as I write this mail :)


 - Misconfigured network card.


 I posted the configuration here. Looks OK to me.



 Two of the URLs I got from the above Google search:

 http://www.linuxquestions.org/questions/linux-networking-3/server-ifup-rtnetlink-answers-network-is-unreachable-problem-340915/
 https://bugzilla.redhat.com/show_bug.cgi?id=155299

 Looked at both of them. Didn't see anything special which could help.

Advice on where and what to study

[Dima (Dan) Yasny]

Hi all,

I'm looking for some advice on which courses and where to take, in the
Central area.

What I'm looking at is getting some more formal and proper programming
background, something around
Intro to C - Advanced C - intro to C++ - Advanced C++ - Linux
specifics maybe...

I tend to mostly work with Python, but I keep running into dead ends
because I lack proper education more and more recently

I am aware of proper BSc/BA programs, but I'd like to do this in under
a year overall, and stay away from the extra math/physics/etc courses.

Background - 15 years sysadmin, bash, python, powershell scripting
Highschool pascal, prolog, magic, assembly etc - long forgotten mostly

So if anyone is aware of a college of institution that provides such
courses, preferrably as a set up program, I'll be very happy to hear
about it


Cheers,
D.

 You could try looking at the open university, but the question is what do you 
 expect to get out of these courses.

I don't get anything out of those I'm afraid - books I can get and
read on my own, but I'm looking for something more structured, and
with more exercise...


 University courses I know don't teach you much about actual programming. I 
 would take at least one course about software engineering, preferably both 
 functional and object oriented, including uml and testing methodologies. Also 
 an object oriented course with emphasis on object oriented methodologies and 
 design. These have proven more invaluable to me than actual programing 
 courses. Computer structure and operating systems have also been very good, 
 but you have to read between the lines, as sometimes the interesting part of 
 the syllabus is hiding behind lecturers who are not even aware of it (initial 
 course in lisp in tau for example)

Computer structure you say? I'll keep that in mind. In general, I'd
like to get a hold of at least a list of courses to look for and their
ordering.



I want to get some proper studies done because I've been touching some
topics here and there, and ended up at a point where I can write a
heavy recursive function in C or Python, but reading a bit of code
where instead of int I see unsigned int puzzles me.

Re: OT: Suggestion for good KVM Over IP?

[Dima (Dan) Yasny]

The native ones are quite OK nowadays - Dell DRAC/IBM IMM/HP iLO...

Anything Avocent should be OK as well

2010/11/29 Hetz Ben Hamo het...@gmail.com:
 Hi,
 I was wondering if someone could recommend a good KVM switch which I can
 connect to servers and control them through the net.
 I have seen few KVM's which gave some crappy display results, others which
 have some issues that when you press a key, it repeats it dozen times (try
 to type an IP like that).
 Any suggestions?

 DRAC/IMM/iLO are great - and I have them on my servers.

 Hetz

Then look at Avocent's line of products - IMM/RSA/DRAC are an Avocent
rebrand really, and I suspect iLO has a lot from there as well

BTW, If you sell fat VPS, based on KVM for example, you can simply
provide VNC access to the VMs.

 *Subject:* Web based file exchange portal

 Hi all,

 I am looking for an OSS solution to the following:
 - Linux (RHEL based) frontend, running on Apache
 - Windows backend and filer, with AD auth
 - Users are able to upload/download files using a web interface (and
 hopefully a windows/OSX/Linux client)
 - File versioning is nice to have
 - Quotas for users
 - FTP access is also nice to have

 The idea is to have a Linux server in DMZ for file exchange control of
 files that are actually in a network that holds the windows infrastructure
 I have checked iFolder (mostly Suse oriented, mono/dotnet based, so I
 probably can't use it). SparkleShare is too raw for production.

 Either way, I don't really need the dropbox-like functionality, just the
 basic file upload/download and permission management, maybe someone can
 advise on an appropriate piece of software I could use


 Thanks

Hi
  
   What about SVN over apache?
 
  That would provide versioning, but large file support would be pretty
 lame.
  All I need is a centralised place to which users from different offices
 can
  upload files, assign permissions for other users from other offices, so
  that the others can download those files from there.
 
  Something like rapidshare, but with access control, or like dropbox, but
  without the file sync abilities (which are nice, but quite redundant in
 my
  case)
 

 Maybe try http://owncloud.org/ .

Wouldn't this be a bit of an overkill? This is a large collaboration portal
with a huge feature set, not a webexchanger

Web based file exchange portal

[Dima (Dan) Yasny]

Hi all,

I am looking for an OSS solution to the following:
- Linux (RHEL based) frontend, running on Apache
- Windows backend and filer, with AD auth
- Users are able to upload/download files using a web interface (and
hopefully a windows/OSX/Linux client)
- File versioning is nice to have
- Quotas for users
- FTP access is also nice to have

The idea is to have a Linux server in DMZ for file exchange control of files
that are actually in a network that holds the windows infrastructure
I have checked iFolder (mostly Suse oriented, mono/dotnet based, so I
probably can't use it). SparkleShare is too raw for production.

Either way, I don't really need the dropbox-like functionality, just the
basic file upload/download and permission management, maybe someone can
advise on an appropriate piece of software I could use


Thanks
D.

Re: official way to load aoe module?

[Dima (Dan) Yasny]

Thinking about it, in this case there doesn't seem to be any gain in using
AoE or iSCSI over NFS. NFS is far from being perfect, but it takes care of
the shared FS, and since the network spped is the bottleneck here...

 I think you should be *very* concerned about the situation where 2
 guests mount an ext3 partition and start to manipulate files
 *sequentially*. It looks like you *are* concerned (rightly), since you
 wrote that only one client *mounts* the partition at a time.

  Another option was to allow all guests to mount the file
  system read/write but carefully configure each guest to own
  different files or directories of sqlite files on the FS.

 What if one starts, e.g., creating files or appending content to
 existing files (and allocating new blocks, etc., in the process)? The
 other clients won't be aware of it.

 I admit I have not thought long and hard about it, but it sounds
 dangerous to me.
