which is why I mentioned 'mkfs+tar' otherwise with dd you need to resize2fs
(or equivalent filesystem resize tool).

SystemImager looks closer to what you're looking and has more functionality.

> Regards,

I don't know of anything already available with such functionality but it
would be cool to build one:

1. On PXE server side, setup a webserver with images

2. Compile a kernel (with all drivers for your target hardware) + an initrd
   with /sbin/init which sets up network, fdisk/mkfs's the filesystem, "wget
   -O - http:///image.tar.xz|xzcat |tar xv" everything as per kernel
   parameters. Or if you're using 'disk images', then "wget -O - |xzcat|dd
   if=/dev/stdin of=/dev/$device".

3. Create per client pxelinux.cfg configuration (in case client's settings
   differ from defaults), with something like:

   linux /vmlinuz
   append initrd=/initrd.gz network=eth0;static;172.16.0.3/27 img=gentoo-x64 
drive=sda

It would be really cool to build something like that yourself :).

Yes, that but AFAIK, you'll get version numbers as part of installed software
name in "hrSWInstalled" table, there's no separate version number field.

not sure about NSClient++/OpenNMS, but if these programs support SNMP, then
you can enable SNMP service in Windows (not remember how), and get all stats
- From Windows in same way, as you've done from any other free OS.

Probably you need to add manual-feed printing option, which requires

Right. And after enabling greylisting, please do notify your email service

If you're planning to block, then maybe temporarily block or tarpit the IP
address in firewall. Usually, MTAs won't do this kind of thing, only abusers.

Or you can also use greylisting daemon, esp. spamd[1] (only works on *BSD) or
postgrey/policyd (or other greylisting software) for postfix.

Anyways, I'll prefer to block them in firewall instead of blocking them in
application.

You need to setup data replication from master database server to slave
servers. And, then in your application logic you've to send database reads
(SELECTs) to slaves and writes (UPDATE, INSERT, etc.) to master.

In case your master goes down, you need to promote some slave as new master,
and update your application configuration, database slaves configuration to
reflect the change.

And, there is also multi-master replication[1] where you can setup multiple
master hosts.

The exact implementation details are specific to the database/application
stack you're planning to use.

I guess by "secure authentication" you probably mean forcing use of TLS, and
requiring SMTP authentication (something like permit_sasl_authentication
after/without-preceding permit_mynetworks), then probably yes. To be sure, you
can try to test your host as open relay from outside your network (something
not listed in mynetworks).

Do you mean something like:


[internet] <---> [router] <> [server]

with router having public IP address, and iptables rules.
 server having dynamic private IP address (like assigned through DHCP),
     and running MTA

Is this how your setup looks like?

If you've placed no access control/restrictions on SMTP server, then only it
can be (ab)used as Open SMTP relay.

Access Control settings are specific to mail server, e.g. for Postfix, refer
to SMTPD_ACCESS_README[1] which ships with its documentation.

I'm not a Thunderbird user, and message hints what the problem is and how to
fix it.

You probably have to clear your "Sent" folder OR check if you're out of disk
space/inodes assuming that thunderbird is talking about local "Sent" folder on
disk. If there is free disk space/inodes (where your thunderbird profile is
located), then you need to bump your disk quota, you'll be needing
admininstrator access for this. Or, if your Sent IMAP folder is full, then ask
your email administrator to bump your email quota.

Are you sure your RTC (real-time clock) battery is not discharged ? Maybe try
replacing the battery.

I used to experience these issues (has nothing to do with RTC) some years ago,
mostly due to crappy SMPS, bad power/data cable which got fixed after I
replaced its SMPS.

And what's that error message you get from BIOS ?

For extended troubleshooting, you can get a POST card[1] (or Debug card), a
PCI card which displays progress made by BIOS by emitting various codes as it
progresses to the I/O port which POST cards hooks itself to, and used to sell
for INR 100-150 few years ago. You'll need your motherboard manual (or a copy
of Upgrading and Repairing PCs[2]), which contains a table to interpret the
codes.

Maybe start with replacing RTC battery, if you've not already done that.

Unless you really intend to learn RPM packaging, I recommend searching for RPM
or SRPM for your corresponding distribution from rpmfind.net (a good RPM
mirror).

There are some problems with .spec file:

> ##

1. You should not be using 'root' user to build RPMs.

2. I assume you want to install in /usr (as you define it in "Prefix" above)
   but default ./configure (i.e. without explicit --prefix argument)
   configures it for installation in /usr/local.

Without seeing rpmbuild output it's difficult to say what went wrong. Please
provide the distribution you're doing this on, and your rpmbuild output.

If by any chance, you're packaging for Red Hat or its derivatives, there is an
RPM packaging related document[1] on FedoraProject.org wiki.

AFAIK, you can't. Usually the way people deal with this, is to setup
everything (= data, usually) on /mnt or mount additional volume elsewhere.

OR may be

if you can mount both volumes on another machine, then you can put setup PV on
both volumes, and create a VG from both PVs, and then a LV of maximum size in
that VG. And after installing everything on LV, with help of LVM enabled
initrd, you can boot from it as well.

[ilugd] [FSF] Stand up for your freedom to install free software

2011-10-17 Thread Ashish SHUKLA

From: "Free Software Foundation"
Subject: [FSF] Stand up for your freedom to install free software
Date: Mon, 17 Oct 2011 19:31:56 -0400 (2 hours, 15 minutes, 29 seconds ago)

Dear Supporters, 

 * Please join us in signing the statement: *Stand up for your freedom
   to install free software*
   <http://www.fsf.org/campaigns/secure-boot-vs-restricted-boot/statement>

The free software movement has come a long way over the past 25+
years. While we still face many challenges ahead for us to create a
world in which it is normal and expected for computer users to have
freedom, we have made steady progress. Right now, however, there is a
potential threat that could put us back years. Microsoft has announced
that if computer makers wish to distribute machines with the Windows 8
compatibility logo, they will have to implement a measure called
"Secure Boot."

When done correctly, "Secure Boot" is designed to protect against
malware by preventing computers from loading unauthorized binary
programs when booting. In practice, this means that computers
implementing it won't boot unauthorized or modified operating systems.
This could be a feature deserving of the name, as long as the *user*
is able to authorize the programs she wants to use, so she can run
free software written and modified by herself or people she trusts.

However, we are concerned that Microsoft and hardware manufacturers
will implement these boot restrictions in a way that will prevent
users from booting anything other than unmodified Windows. In this
case, a better name for the technology would be Restricted Boot, since
such a requirement would be a severe restriction on computer users and
not a security feature at all.

We're looking at a world in which it could become impossible for the
average user to install GNU/Linux on any new computer, so too much is
at stake for us to wait and see if computer manufacturers will do the
right thing. "Secure Boot" could all too easily become a euphemism for
restriction and control by computer makers and Microsoft -- freedom
and security necessitate users being in charge of their own computers.

So please, join us in signing this statement against Restricted Boot,
and consider encouraging your friends, family, and colleagues to do
the same.

If you are part of an organization or company that would like to
prominently show their support, please contact us at
.

For your convenience, here is a list of additional articles and
resources related to this statement:

If that covers "photography", "post-processing", etc. using FOSS of-course,

I forward this query to a friend (not subscribed to ilugd list) who has
experience in this domain, and following is his reply:

- --8<---cut here---start->8---
As for as my knowledge and exposure is concerned none of the Indian
and, or foreign brokers provide a native Linux based trading client;
though there are some based java VM, but I tested and, or used TWS
(Trade WorkStation) from Interactive Brokers only, which is too
primitive or does not have even the very basic features a modern
traders needs.

Nothing is perfect in this world, not even the God, hence I had been
struggling with whatever the brokers provide. I sent requests to many
Indian brokers join hands for developing a F/OSS TC (Trading Client)
based in an industry standard FIX protocol around 3-4 years ago, but
none bothered to care and, or provide information or API (Application
Programming Interface) for their servers.

If we leave aside, trading terminal part, we have a nice native
Technical Analysis platform developed on and for Linux and Unix-like
systems, please check http://qtstalker.sourceforge.net/ for further
details.

You need to explicitly build an initrd (or initramfs), and it's not mandatory
to have an initrd.

Did you look in kernel config ?

[ilugd] Dovecot2 mdbox issues, and mailbox synchronization between hosts

2011-10-10 Thread Ashish SHUKLA
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA512

Hi,

Has anyone tried copying Dovecot's mdbox mailboxen (in Dovecot2) from one host
to another which might/might not run same minor version of Dovecot, or a
different operating system platform together? Is that even recommended?

I'm asking because I copied my mailboxen from one host (GNU/Linux) to another
host (FreeBSD) and all email folders seems to be messed up, as in some older
emails are showing in all email folders. Since I migrated to Dovecot2 from
Archiveopteryx in a bit ugly fashion, and I didn't notice this problem then,
I'm not sure whom (in addition to myself) to blame for this. But has anyone
experienced any similar problem?

Also, what's the recommended way to synchronize mdbox mailboxen between hosts?
My desktop which I regularly use runs FreeBSD and Dovecot 2.0.14, and my
notebook which I only use when I'm traveling, runs Arch GNU/Linux and Dovecot
2.0.15. I would like to synchronize my emails (keeping email read/unread
status) from desktop to notebook and vice versa. Should I just perform an
rsync (or nc+tar, in worst case) OR should I use some IMAP aware mailbox
synchronization program (like imapsync) ?

Sorry I forgot to mention that parameter is specific to ATI/Intel
hardware. There is a page[1] on Debian Wiki related to this. Although Debian
keeps that disabled but since you're running Vanilla, it's probably enabled.

Also just curious why are you running custom kernel? And if you've to run it
on Debian hardware, may be compile it with minimum options i.e. based on the
2.6.18 .config you're running. You will encounter that couple of options
aren't present in 3.0, but you've something good to base upon. And since,
you're running Debian, build/install your kernel the Debian way[3], which will
also build an initrd for you as well. I'm not sure but I think you'll probably
need one to boot Debian's init. IMHO, being able to package custom kernel
using built-in tools is one of the cool things about Debian.

AFAIK, there is no Debian 4.1, you're probably running Debian Etch 4.0.1 or
similar.

No, kernel-mode-setting here refers to enabling graphics mode from
kernel[1]. The problem here _seems_ to be that kernel you're trying to run
supports kernel-mode-setting, and has probably that enabled by default, but
userland (Debian Etch) isn't expecting kernel-mode-setting, as
kernel-mode-setting functionality only got introduced after Debian Lenny,
i.e. 2.6.28 and later. So, try booting with "nomodeset" kernel command-line
option, not sure if that will work.

What's your kernel command-line ? And is your kernel gets stuck in graphics
mode, or text mode ? And what happens with your keyboard LEDs (assuming you've
one of those keyboards which come with Caps/Num/Scroll Lock LEDs) when this
happens ? Which distribution are you using ?

My guess is something with kernel-mode-setting is fscked.

Looks like some process (maybe httpd) is already listening on port 80. You can
see that using:

# netstat -pant |fgrep :80

> 2. Also service command is not installed

> root@ip /]# service httpd start
> bash: service: command not found

Try using "/sbin/service". Are you sure /sbin is in PATH and you're not
running something like "sudo su" or "sudo bash" to get root shell. It's
provided by "initscripts" package (which is usually installed as part of base
system, IIRC) whose existence you can confirm using:

% rpm -q initscripts

If it's not installed then you're probably missing the Base group as well,
which you can install using:

# yum install -y Base

I assume you meant connected to the server, and started screen, i.e. screen
should be running on remote shell, not locally. Otherwise it won't help with
the problem you're facing. And, if you decide to go for "tmux", then it also
needs to be used in a similar manner, i.e. started at server end.

If you've never used screen, then I recommend using tmux[1], it's a BSD
licensed superset of GNU screen. Users of GNU screen might find it bit odd.

You probably mean to run "screen" in "ssh", i.e. screen on remote end?
Otherwise with "screen to run your ssh in", instead of using GNOME terminal's
pty, you're using screen's pty, with nothing changed at the network interface
level.

Do you get the same IP address on both interfaces?

I don't own a i3 desktop, but an i3 notebook (Lenovo Z560) which has a Realtek
NIC, and a Atheros 802.11 bgn NIC. And it works fine with Linux, DragonFlyBSD,
and FreeBSD.

May I ask what problem are you facing with those mobos?

I never used Oracle software, so assuming that its SQL client works something
like "oracle ${USER} ${PASSWORD} ${SQLSCRIPT}" and you have all your scripts
in same directory ending with .sql extension, then with Bourne (or compatible)
shells you can do:

$ for i in *.sql; do oracle ${USER} ${PASSWORD} $i ; done

OR if you like to concatenate all .sql files, then:

$ cat file1.sql file2.sql  >>../big.sql

Thanks for mentioning. I never thought about the person behind this effort

With hexacore CPUs, fast memories, SSDs, NICs available for desktops, I guess
the gap is getting narrower. And IIRC, the article is about desktop class
hardware ;)

Could you please explain, what you mean by that?

Not anymore. Thanks to paravirt_ops[1] kernel support which was present in
Linux kernel since 2.6.23, you can use same kernel to boot as dom0, domU, or
without Xen. I've never used VMware ESX (nor I intend to), but from what I
heard it's more like a virtualization OS made to run on bare metal, unlike Xen
which doesn't restrict you in this way, so you can use dom0 for different
purpose.

- From the abstract, an article about Virtualization stack, that excludes Xen
seems incomplete. You can run Xen on your X11 GUI enabled GNU/Linux box which
you use daily for watching pr0n, hanging out on social networks, writing code,
etc., and run VMs, and get better performance with VMs (paravirtualized). Not
sure, why you think Xen is enterprise only.

And also to read that article one needs to subscribe to the magazine, but
they're mising the  tag around "click here".

As I see, you're the author of the article and hoping for some feedback, you
can probably make it easily accessible i.e. without requiring LFY subscription
as well, thought I'm not sure if that's allowed.

It seems something is not fine between you or server, either your server is
sending the RST or some intermediate router. Best way to find this is to
tcpdump. Also did you recently changed anything on server, like upgraded git,
tried to secure it with some ACLs around some PAM module ?

Also can you scp the working directory to the host, and then try pushing from
there to confirm that git-push works?

And try creating a new git repo (for testing) and push some test commits to
there (from your local box), and see if that works? Make sure your new repo is
under the same user as previous repo.

Yes, UseDNS is only useful in ideal internet where reverse DNS exists for
every IP address, and when it exists it matches forward DNS entry. Also adding
"UseDNS no" avoids the extra delay one has to go through during SSH login when
SSH tries to perform reverse lookup for your IP address, and weird thoughts
which comes with SSH connection taking time to login...

Did you try booting in "recovery mode" from GRUB menu, or old kernel versions
(iff they're available) ? You probably need to press "Esc" during booting to
see the GRUB menu options.

And were you using KVM before this? And upgraded/changed BIOS settings
recently ?

You're probably missing some Init strings from what I've seen on other data
cards. A Google search pointed me to a PDF[1], which contains additional
connection string(s) you're missing above. If that doesn't work, and you can
get a Windows box for sometime, then you can turn on Modem logging[2] and
figure out precisely what strings what their dialer sends to the modem.

I've MTNL 3G, I use it with datacard provided by them. The datacard driver
works fine in GNU/Linux, and FreeBSD. The only problem I face is 3G latency (+
~30ms), and highly unreliable MTNL routing which most of the times takes you
to .de/.us in ~150/250ms, but sometimes takes +150ms.

The speed (200-230 KiB/s to mirrors.cse.iitk.ac.in) is good, and with
unlimited plan, you can download great amount of pr0n (but if you're on high
latency place, you'll end up shooting yourself in foot with 100s of
connections in SYN_SENT). Roaming is free all over India and actually works
with same experience (at least in Kanpur), courtesy: Bhagwan Se Nahi Lagta.

Other than being yet another IRC network for Indian users, and ofcourse hosted
outside India ;), is there any special point of joining it. IMHO, a better
thing would be to create a .IN hosted IRCd node to existing popular networks
like Freenode, or EFnet. I don't see any nodes in Asia of both of these

It seems you're missing "kernel-devel" package, please install it.

And you don't need "root" user to compile the driver (i.e. "make"
above), only for "make install" (if there is any such step).

Also did you try the "uvcvideo" driver which ships with kernel ?

In most of the SMTP servers I encountered, SMTP authentication part is
delegated to external SASL authentication backend, Cyrus or Dovecot
commonly.

So if you're going to setup SMTP authentication, you need to configure SASL
backend. In your SASL backend configuration, you can configure what
authentication methods you want to expose. If you decide to use backends like
PAM in your SASL backend configuration, then LOGIN or PLAIN are the only
backends you can use.

Assuming FS is filesystem, I don't think so. Try repairing table, check
database's error log if it crashed.

Assuming "var/article" is a filesystem object, maybe try DRBD[1] ?

Maybe look at Heartbeat[2], or Wackamole[3]. Keep DB and FS replicated and
make your webserver listen on virtual IPs (aka service IPs), and use Wackamole
or Heartbeat to migrate IP addresses during failover.

I've not worked with OTRS since a long time. Don't remember much of its setup
now.

Maybe try to strace(1) Thunderbird process, it should give you some hint where
it's spending time.

% strace -p $pid

Also check if there is some other process (launched by Thunderbird) causing
that (top(1)). I hope your $HOME or / (root) is not mounted over NFS, is it ?

Thanks for the link. So now that makes it official :).

I'd a similar experience Some years ago when I use to work on Gentoo Hardened,
hoping to port (or better package) couple of SELinux goodies shipped with
Fedora (e.g. setroubleshoot) to Gentoo environment, I was never able to get
source tarballs of the latest RPMs. The tarball versions which were available
on the project site (somewhere on fedorahosted.org) were quite old compared to
what Fedora was shipping. And the only way to get them was to extract them
- From their SRPMs and host them somewhere.

This is just the beginning. To make third-parties to support RHEL harder, I'm
sure there is more obscurity coming up.

Thanks

I'm not sure about this, but ntfs-3g is a FUSE filesystem, and FUSE
filesystems require a user-space daemon, to respond to filesystem requests
- From kernel space, which is probably not available at the time of boot (from
initramfs, I assumed it, as it's not much clear from your post where you get
that message).

Just to verify this conclusion, replace ntfs-3g with ntfs (the read-only and
limited write capabable driver present in kernel), and mount options to
"defaults,ro".

If this evaluates to true, I recommend restoring "ntfs-3g" line, and adding
"noauto" to mount opts, so it only get mounted by mount/HAL/DeviceKit
(whichever in use), when you explicitly try to mount it, or try to browse the
filesystem of the disk in explorer, or remove it from fstab(5) completely and
add it to autofs[1] (not sure if this is going to work at all).

The command is just the name of command, you'll probably need more detail
(e.g. command-line, environment variables, etc.) to be able to precisely point
out, what it's executing.

For command-line:

% cat /proc/$pid/cmdline |tr "\0" " "

For environment:

% cat /proc/$pid/environ |tr "\0" "\n"

ps(1) can also provide this information, e.g. ps auxe

Ofcourse you probably have tried this, but let me mention this:

0. Have you tried passing various values for "model" option[1] corresponding
   to your snd-hda-intel chipset (ALC269).

1. Trying with latest ALSA sources 1.0.23 instead of 1.0.21 ?

2. Not ALSA related, how about ditching ALSA and going with OSSv4[2] stack
   which is also getting fairly good support, work great and its mixer is as
   confusing/complex (or maybe more) as ALSA. And ofcourse it's licensed under
   GPLv2 and BSDL, which makes it free software as well.

Yes, but that's not good in long run, esp. when people figure out your
strategy. ;)

Everyone needs support. Unless your willing to maintain software stack on your
own, you'll need some one to maintain it, that's what support means. Be it in
terms of porting your customizations to new versions, tuning it for
performance, developing addons etc.

How about maintaining a kernel for n years, and backporting new hardware
support to it, while avoiding the bugs which come with new kernels ?

I use torrents from my Airtel connection extensively, and have no problems
with that. I started off with bittorrent's official client, and then ktorrent,
vuze, transmission and finally ended up using rtorrent in a screen.

ktorrent, Vuze, etc. ship with UPnP support in form of plugins which you've to
activate from there menus, and work great.

Slow torrent downloads could be due to several reasons, from low no. of
seeders, to a large ratio of seeders and leechers, to the firewalls, to the
lack of encryption support in your client. These days large number of users
prefer to accept only encrypted connections, so that could also be one of the
reasons. Use a software which also supports various other mechanisms of
sharing peers like PEX, DHT, etc. as well.

To die chosing them, that's for the freedom :)

You probably have to manually forward the ports (inbound port, DHT port) in
your ADSL router, if you're using it in PPPoE mode (the default mode)
configured by them.

It also depends on the torrent client you're using, the clients with UPnP
support (e.g. KTorrent, Vuze (IIRC)) automatically forward ports for you.

I hope you're aware that grub (legacy) expects configuration (menu.lst or
grub.conf) to be in /boot/grub, and assuming your /dev/sda1 or (hd0,0) is
mounted as /boot in fstab(5), then I hope you've /boot symlink (pointing to .)

Actually gcalctool has similar feature in form of registers, which in
*Scientific* mode, I can use with '<- R' and '-> R' keys on gcalctool 5.30.2.

Hi

Has anyone any recommendations about ergonomic keyboards available in Delhi ?
I've decided on Microsoft Natural 4000 keyboard, but I'm wondering if anyone
has any better recommendations ?

Please don't recommend Kinesis keyboard unless you know where I can get it in
Delhi.

Thanks in advance

I happily used Jext[1] and jEdit[2] during my M$ days on a box with 256 MiB

[ilugd] [OT] Free IPv6 Certification and Free T-Shirt!!

2010-07-29 Thread Ashish SHUKLA
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA512

Hi everyone,

Happy SysAdmins Day :).

The *Free* mentioned in the subject is free as in free bear (which you see in
free TV channels).

Anyone who wants to try out his IPv6 skills and can try the free online
certification[1], which includes quiz and some practical tests, provided by
Hurricane Electric. You'll need:

* Connectivity to IPv6 internet, native or via tunnel[2][3]. AFAICS, the only
  tunnelbroker in APNIC region catering to .IN is HE at Hong Kong.

* Knowledge of IPv6 protocol.

* A domain name (for which you're able to set WHOIS information) to point to
  IPv6 nameservers for creating IPv6 glue records.

* A box which is capable of running web-server/mail-server on IPv6 sockets.

The certification process is divided in various levels. And after reaching
'Sage' level and confirming your snail mail address, you can get a T-Shirt[4].

The T-Shirt can be seen at following URL:

http://www.tunnelbroker.net/forums/index.php?topic=1069.msg5695

Lets hope Indian ISPs also come with such public trials to ease the
transition.

If you need help, you can post here (unless prohibited by list admins), to me,
or better /join IRC channel #ipv6 on Freenode or EFnet.

[ilugd] Wikileaks To Leak 5000 Open Source Java Projects With All That Private/Final Bullshit Removed

2010-07-29 Thread Ashish SHUKLA
 third-party Java library
vendors can refactor their code to make certain classes more
reusable. Blackburn declined to describe these refactorings, claiming it was
"none of y'all's business."

Guy Faulkner, a 51-year-old Python developer in Seattle, was amused by the
Wikileaks announcement. "When Python developers release Open Source code, they
are saying: Here, I worked hard on this. I hope you like it. Use it however
you think best. Some stuff is documented as being subject to change in the
future, but we're all adults here so use your best judgment."

Faulkner shook his head sadly. "Whereas Java developers who release Open
Source are code are saying: Here, I worked hard on this. I hope you like
it. But use it exactly how I tell you to use it, because fuck you, it's my
code. I'll decide who's the goddamn grown-up around here."

"But why didn't they write that Perl script in Python?" Faulkner asked.

With apt-cacher you need to run a script apt-cacher-import.pl, after copying
the already downloaded packages in 'import' directory, which copies packages
in 'packages' directory and registers in its cache db.

I'm not sure about 'apt-cache-ng', never used it.

I used 'apt-cacher' and 'pkg-cacher' both of which act only when they receive
an HTTP request from one of the clients. They're usually installed as a CGI
binary, or as a standalone web-server. And when they receive a HTTP request
for a file, they perform a cache look-up, and if the file is in cache, they
serve it from cache, otherwise they initiate downloading from the source. The
first time one of your client updates itself, a 'cache miss' will happen and
the packages will be downloaded. And for subsequent updates, the packages are
served from the cache.

The file names of the downloaded packages have architecture mentioned in them,
so you don't have to worry about 32-bit packages getting overwritten by 64-bit
ones. And I used a single repository with apt-cacher and pkg-cacher.

SFTP = file transfer protocol (not FTP) over SSH. You can create SFTP-only

The reason I suggested is because entering a username/password in a dialog box
looks straightforward to me, and SFTP url will be the same. You can configure
OpenSSH in chroot mode[1] preventing users from exploring the server 
file-system.

And also if '/$un/' share requires authentication, you're entering same
username twice, one at your script and other in the user/password dialog box
which nautilus pops up. SFTP offers secure access and is well integrated with
Nautilus and GNOME VFS.

Instead of putting up an SMB server, why not use an SFTP server and an NFS
server ?

NFS server for anonymous mounts. And SFTP for authenticated mounts.

And instead of having this script, why not initialize the ~guest with a

What you need is a kiosk setup. There are lots of links about that on the
Internet, including one by jwz[1]. Or a modern (and of course recommended)
way, using pam_namespace[2]. Fedora used this in Fedora Kiosk spin[3], IIRC.

I also used apt-cacher in past and it worked but recent versions had some
issues, so I kept the old version pinned on my Debian box.

I also tried pkg-cacher[1] because I needed to cache for 'yum' (fedora/centos)
also and it worked great since it can cache both 'yum' and 'apt'.

There are guidelines by Gmail[1], Y![2][3], and maybe others. Try figuring out
what they're and comply with them.

Usually, they include an opt-out link, DKIM signatures, SPF, etc.

AFAICS, sysvinit[1] is not packaged for latest version, so either you've to
re-package it for newer version yourself or get it from Debian which has
recently introduced parallel booting[2], or ask in #ubuntu for some switch or
some reconfiguration to reduce the impact of upstart, or try packaging
systemd[3] and playing with it.

I think we need zero restriction on freedom of speech and more respect for
preamble of the constitution, both of which require tolerance from the people,
and other things will follow.

Maybe you should think about how to distribute 1984, and other Orwellian
thoughts in their naked uncensored form, like Gideon's Bible.

FYI, Facebook is not a platform developed by techies for common people to
share ideas, it is just another man's dream of becoming a Big Brother, by
employing techies, like Google.

And the worst part, Governments uses that to communicate with people for which
they're not even sure is happening behind the scenes. We need more public
domain work by Govt., and no copyright by Govt. We need institutions like
C-DAC to be shut down for acting as a Govt. funded for-profit organization.

We need sources for all of the work (including websites operated by govt.) in
standard format (read as: !OOXML or encumbered by patents) in a freely
downloadable fashion, and zero security by obscurity.

And for that we don't need another constitution, just n amendments will do,
but there are very less chances for that happening now unless everyone goes in
M-x paranoid-mode.

What I can see from your essay is that you're trying to make a career in
creative writing and wanted to make your résumé look better:

  * Lead team of n people and drafted a constitution, under CC-by-SA, not
*public domain*, available from Lulu.com :)

I wish I could write something like that on my blog :( .

You probably mean CLASSPATH for Java applications, which you can set by
passing '-cp' argument to the 'java' command-line. For details, RTFM java(1)
OR the documentation of the Servlet container, if you're looking for
configuration of your servlet container.

1. Install OpenJDK, IcedTea or Sun JDK, whatever your GNU/Linux distribution
   provides through its package repository. Download JDK from Sun iff your
   distribution doesn't provide packages.

2. Install a servlet container (e.g. Apache Tomcat[1]), by downloading and
   extracting the tarball in your $HOME. This is preferred, even when
   distribution provides a package for the same in their repository, as most
   of the distributions tend to split the package according to their file
   system hierarchy conventions, which conflicts with the paths you encounter
   in the documentation, which you might find difficult. Other than this there
   is no harm in distribution packages, on the contrary for production use,
   always go with distribution's packages whenever available, OR package it
   yourself, if packages aren't available.

3. The rest of the steps (like starting/stopping) should be same as
   Windows. The configuration should also be the same with just the difference
   in path conventions.

tcp_wrappers only comes into picture after accept(), but here connection is
timing out, which hints at packets being dropped.

Yes, I'm able to telnet to port 25.

thats because you're using traceroute6 which is looking for  records. Use
tcptraceroute[1] to figure out which host drops the packet.

Looks like firewall is dropping packets.

But, since I can connect to it from here, so I think your ISP might be
dropping packets destined to port 25. Try tcptraceroute-ing.
