Re: [ilugd] Sendmail Relaying

2012-12-18 Thread Naresh Narang


I have a local mail server on MX for my domain. Sendmail configured as MTA.
Users are able to send mails to each other. For relaying mails to outside
domains, I'm using SMARTHOST for my hosting. Now I'm trying to send the
mails directly to the outside domains, I've created the SPF records for my
domains with all the ip's sending mails for my server and the reverse DNS
entries for the IP also. But still i'm getting mail bounce error from many
domains stating

1. This message has been blocked because the HELO/EHLO domain is invalid.
2. host mta6.am0.yahoodns.net [98.138.112.38]: 554 Message not allowed -
[299]

And many other. Please guide what more I've to configure to make my
internal server relay mails to outside domains,



Test your sendmail with:

sendmail -bt -d12.21
>$m

and see what domain it thinks it knows about.

OK, please start a campaign to "educate" the millions of users who

Alternately, or mandate the vendors of such devices to put such rules
by default into their devices.

Check routing table to confirm, even so, RFC 1918 should be null routed on the

Two ways:

1.  Use "dd" to copy entire hard drive.
2.  If disks are in a mirror, take one disk out and use it, new disk in

Re: [ilugd] Question about iptable rules for SMTP

2012-02-04 Thread Naresh Narang


Sorry, I was not clear in my description.

I am setting up iptables rules for the server that is the MTA.
What I wanted to have was SMTP input packets routed only to
the server, and SMTP output packets routed only from the server. I
know how to do that, but as the server IP is dynamic, it would
make life easier if there were no security issues, and I could
ignore source/destination packet routing.

---

1.  Server talks to outside world using SMTP (or ESMTP) - so SMTP rules apply 
there.
2.  Clients (or users) talk to server using POP3 or IMAP or whatever else.
3.  Server outside (public) IP cannot change and so server's private IP should 
also be fixed. This because you wouldn't want DNS MX record to be dynamic or 
you'll have problems receiving mail from outside world.
4.  Server is able to communicate with pop3 clients unrestricted - with secure 
communication enabled.
5.  Server is able to talk SMTP to any other MTA but is not open relay (meaning 
that it can send and receive emails for its own domain only). Can use TLS but 
not all MTAs may support it.
6.  Email spam is controlled by having email go through a spam filter software 
(kind of a proxy to receive mail from outside world), that filters spam and 
suspected virus emails etc and then forwards to your MTA.
7.  Routing to or from SMTP server should work as such but plays no part in 
security.


Hope it helps.

I would think each of these topics are at about 3 - 4 days class on average. 
The cost of SAN is huge so it makes me wonder if anyone can provide this 
training without charging a ton of money. Also, I think one needs to be clear 
about what you want from this training and what you will get. Have at least 
some idea of what is a SAN environment that you can expect and get to work on 
(if any). SAN is more than just a "drive".

Yes then printer becomes part of VLAN A and works, in which case it goes out of 
VLAN B. What would users in VLAN B do if they were using this printer already? 

There is no need to move any switch ports out of their current VLAN or change 
any IP addresses as long as routing between VLANs work and ports (not physical 
switch ports) are open between them.

If VLANs A and B can route traffic to each other, it should just work after you 
configure - no different than how you would do if they were in same VLAN. If 
there is a firewall between them, then you allow ports that CUPs needs.

Things to check -

1.A firewall or iptables not allowing port 25 to this server from outside.

2.   Qmail not listening on public IP or private IP Natted to public IP but 
listens only on localhost.

3.   Any tcpwrappers not allowing access.

4.   SELinux active and not allowing access.

Postfix has nothing to do with this. Public IP of sender needs to reverse 
resolve to a valid domain to avoid being sent to spam.




Did you meant RDNS it is already set to the hostname of the server i am sending 
emails from, 

-

Well, if your server has a FQDN and resolves to reverse DNS then it has to be 
unblocked from the sites that marked it spam. SPF is good to have for those 
servers that recognize it.

1. Blacklisting in RBL/DNSBLs Server (use robtex.com to check)
2. Absence of PTR Record.
3. Wrong SMTP Banner.
4. Subnet may be in a pool which has mail server as open relay server (very

5. SPF Record.
6. The Server may be a real source of SPAM (quite possible that you are really 
spamming).
7. Proper CNAME if A Record is something else.

9. For complete consultancy and solution, user needs to pay me [Commercial].




Great, please explain these items being the reasons for being dumped as SPAM -

Blacklisting in RBL/DNSBLs Server (why did it end up in spam was the question 
to begin with, chicken or the egg first.)

Wrong SMTP Banner. What significance does it have except legal.

SPF Record (20% utilization as of 2008).

The Server may be a real source of SPAM (how do you determine this in absence 
of other facts mentioned.)

Proper CNAME if A Record is something else. Whose CNAME and A records, please 
elaborate.

Opt In and Opt Out options. - Really? I get dumped in SPAM because SMTP server 
didn't find Opt-in, Opt-out in my email body? Now that's scary I think. How 
does SMTP server determine if my email was a marketing email or not. Your email 
didn't go in SPAM either though there was no Opt-out mentioned.


Others are pretty obvious. Correct configuration of Postfix assumes that it is 
not open relay, which mostly are not by default. Pay you, yeah that's the 
reason.

Postfix has nothing to do with this. Public IP of sender needs to reverse

I think "Domain Controller" is specific to Windows. You can probably use LDAP 
server and do authentication but I'm not sure it supports or if there is 
something else that comes with all the bells and whistles of a Domain 
controller.

Yes it is possible. Samba can act as domain controller. There is documentation 
on Samba web site.

No, don't need both, Secondary is a backup of primary in case primary became 
unavailable for some reason.

I have used Winbind (part of Samba) and Kerberos encryption to authenticate 
Linux box with Windows AD server (documents on Samba web site) but should be 
possible to do it with OpenLDAP.

Cache is usually small and kernel is supposed to handle that part, I don't 
think it can be increased. To me it looks like there is a problem with paging

See if you have disk cache turned off. If so turning ON disk write cache should 
alleviate this problem but you better have your box on UPS.

When I first saw my AMD CPU temp at 70 C I was alarmed too but I think it is 
"normal" for CPUs to have temp this high, since CPU is the hottest thing in the

Depends on the budget, ideally you want to have a dedicated server for each

I was talking about removing the disk completely, you
cannot remove it and leave it there, you have to replace it.
If it was the hot spare you removed, sure you can but you
lost the hot spare function. 

Yes you can remove disk replace it if server supports hot
swap. Number of disks you can remove depends on what Raid
level you are on e.g. you cannot remove more than one drive
out of Raid 1 and 5.

My

Ok good explanation on expanding a Raid 0, expanding the
LVM and hence VG. I suspect this does not mean data that was
on the first drive ever got moved or distributed into
second. You didn't say if you pulled the drive out of
the bay after this expansion. I think pulling a drive out of
Raid 0 will be disastrous right away if data was distributed
on both drives. A single disk in Raid 0 has all the data on
it and hence may be functional even after you pull out the
newly added drive that did not contain any data.

LVM cannot protect you from disk failures. LVM is good
strategy if you want to dynamically expand or contract file
systems. It does not and cannot change the basic principles
of Raid levels and their meaning. No file system can protect
you if you lost 2 drives in a Raid 1 or Raid 5 system for
example.

Once array has been created, you cannot remove disk. Removing one disk from 
Raid 5 set will cause array to become degraded, removing 2 disks will fail the 
virtual drive with loss of data. If array is not in use or you don't care about 
data you can break the raid set and create new. Sun's ZFS file system is more 
fault tolerant.

Besides the security issues (unless it uses VPN), I
suspect, even if it works, may be unreliable. I would
do rsync using ssh or tar + gzip can be used to move
files.

A while back I spent much time struggling with ATI

Various options -

2.   Dedicated T1 line.
3.   IPSec VPN.

Connection speed will depend on available bandwidth in

Intel's FSB architecture is a bottleneck but they may
have overcome this with dual core etc. AMD does seem
slower when compared with same clock speed Intel,
cache definitely plays a significant role. Intel has
come up with low power CPUs that can be considered.
AMD may be better where 64 bit processing is required.

Don't give them root password, give them sudo access.
You can either restrict them to only use commands that
they need or give them full access. You should be able
to see who ran what command but this is not guranteed.
You may want to run Tripwire or something similar for

Hi there,

1.   Why are we scared of Microsoft being there in the
event?

2.   BTW as for the reason, Microsoft have their Linux
infrastructure in house to work on and do research.
They are taking on things that work in Linux and make
changes to their own products.

3.  By similar argument, why can't we take Linux in a
.NET event to just show anything that works?

It doesn't do much good, if we can't show TCO will be
less with Linux. Be realistic, why many people are
afraid to take on Linux ;)

   Most laptops will look similar on their advertised
features - like number and speed of processors, amount
of memory etc. 

While choosing a laptop, I would look at -

1.   What warranty they offer for parts and labor.
2.   Their memory speed and whether they offer DDR or
DDR2 type. Hardware goes obsolete in less than 6
months.
3.   What is their "Front Side Bus" speed (in case 
Intel), makes a huge difference in performance when
compared between same kind of CPUs.
4.   Need high performance graphics only if I need to
play games / watch movies or other scientific
computation involving images.
5.   Does it have a DVD ROM or DVD RAM and what
formats of DVD it supports.
6.   Does it have a DVI video output as it is going to
replace VGA standard.
7.   A security chip is nice to have.

1   Does it get detected?
2.  Do you have drivers to enable it?

  If yes to both, it should just get attached to a com
port like any other modem.

   Depends on what you did during install but from
this description most likely this is what happened -


C: 10 GB - Primary NTFS = Win NT/XP
D: 4 GB - Primary VFAT = Win Xp Home

   You booted with the label "Win Xp Home" (the
recovery section) and it tried to recover your laptop
to factory default settings and rewrote the MBR.
Apparently it seems like the rewriting didn't go very
well as it should have just booted into Windows
without giving you any prompt for Grub. Now I wonder
if the Windows partition is still intact and available
to you.

Try this -

   Your local mail server is xyz.com and [EMAIL PROTECTED]
lives on ISP. 

Create a user x11 on your local and in his home
directory create a .forward file 

In this file, use mail address with ip address of your
ISP's mail exchanger like so 

[EMAIL PROTECTED]

What you are trying will NOT work. You can't tell
your mail server that he is xyz.com and at the same
time there is another xyz.com sitting out there
somewhere. You should change your local domain to say
abc.com and users can use "xyz.com" in their "From"
address to achieve what you are trying to.

I think the question is not "Why doesn't Govt.
adopt?". the question is "How will Govt. adopt?"

Consider this -

-  What is computer literacy of people governing?
-  Even if some of them are aware, they probably want
a turn key solution that they don't have to mess with
because there may not be enough people to manage it
and people get transferred. Therefore they find it
convenient to go for already established brands and
names.
-  How many people in Govt. have vested interests in
going for a particular brand.
-  How many computer engineering graduates would
actually like to work for Govt. (leave alone few that
go from IITs to join IAS). Even if some of them do,
they find it difficult to continue due to various
factors like reservation policy, corruption etc.
-  Shouldn't Govt invite fresh graduates from collages
and seek their opinion?



and so on...

Security - This is a big subject. With either, you can
never say that you are entirely secure. There may
always be bugs and there may always be security
vulnerabilities. To me, you should start with looking
at what do you want to secure, and then secure that.
There is a trade off between security and convenience.

2.  Bugs - Every once in a while bugs come out. I am
not sure I saw any company giving out software with a
label "Bug free". There may be performance bench marks
available to look at what will work better in a given
environment than other. I have seen various flavors of
Linux (commercial and non commercial) being used in
production. You may also want to look at if there may
be any compatibility issues with other hardware / OS
or availability of certain drivers if you need them.

3. Frequency of updates - depends if you have security
issue or performance issue or no issue, just wanting
to apply updates as soon as they come out?

4.  Apache - I have not seen too many security issues
coming out with 2.x recently, but you never know.
Given a choice, I would go for 2.x version.

Re: [ilugd] data recovery

2006-02-05 Thread Naresh Narang

   Data is logically deleted. If nothing has been
written to the disk after delete operation, most
likely it is still there. You may need to use some
disk tools to recover data from those cylinders that
may be showing as free space now.

Compare L2 cache. It makes difference depending on
use. If you are just surfing web and checking Emails,
it doesn't matter.

Cost.

If you are going to or able to use 64 bit feature then
yes, its good to go for Turion-64 otherwise bells and
whistles.

Some Lenovo R series have security chip in them that I

could create your encrypted file system with it.

Toshiba and Lenovo are reliable. I've heard bad

Everyone has its own pros and cons, your choice may

On a side note, if you are going to buy wireless, you
should buy the one that is 802.11g compatible. 802.11b
is old and slow and may not work all the time due to

Try kppp. Set modem to /dev/ttyS0. Check if you have
