Re: ZFS on Linux (Was: Corrupt file system)

[Baruch Shpirer]

ZFS is ok, i had over 100tb on it on supermicro storage servers
You can optimize read/write using zil/l2arc
But didn't find it 100% stable (lost pools twice) thus only used to
archive/cold storage
The usage was pretty intensive (over 40 million files, sub 200k) though
But a lot could have changed since than (2011)...
That's my 2 cents

RE: ot: multiple wifi AP for covarage

[Baruch Shpirer]

If not using roaming under WDS or repeater/expander you can use AP with same 
SSID and configure roaming aggressiveness to medium/high

 

See example:

i tried to put all APs with same ESSID, but that no help

 

I think that it's not enough that all the APs have the same ESSID. You also 
have to verify that the security settings are exactly the same on all of the 
access points, and that each access point is using a different channel.

 

 

using a repeater if i understand correctly will not help either (and i get 
worse throughput)



any idea ?

Too many ways to do this but if you consider the data you are going to put
on this nas valueable and the hw you are talking about is 2+yrs old then
you better off buying new

With old hw you can never be sure its going to come up next time and
basicly nothing is promised, but for sure stuff can still work for ever

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:

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

Thanks. That is unfortunately nothing that I want. :-(  I already have  
a similar adapter with a US line. It works perfectly fine without port  
5060 redirect to it. I also do have an asterisk system, but it uses a  
different SIP port. IMHO having port 5060 open to asterisk is a way of  
finding the security holes in your asterisk system when you get your  
monthly phone bill.

As for the phone number, I've had this 02 number for 14 years and  
would like to keep it.

It's interesting that it works for faxes. Most VoIP won't unless you  
have t.38 fax machines at both ends and t.38 fax support all along the  
way. I think it will work with standard fax machines with ulaw or alaw  
codecs, but they use a lot of bandwidth.

RE: asterisk and bezeq

[Baruch Shpirer]

They have a voip service for home (076) in which they give you an MP202
adapter with 2 FXS ports
And also a hardcoded softphone but both need port 5060 UDP redirected inside
to used computer/mp202 lan interface
 
I just got it for faxes as it cost 7.99/month without calls but calling from
it isnt more expensive then bezeq
Ill get it checked with asterisk soon enough

Hi, 

Following your question, I tried to find information about the service you
asked about on Bezeq's Web Site in English - astonishingly: there is't a
word in English on the site!

When I click on English at the top I get to the Inverters Relations page

The service is called Bphone. It seems to be a VOB line that you can access
by installing an app called Phone Dialer on your cellular phone. I couldn't
find what's the software for the PC...

You could call 199 and ask for an English speaking representative and ask
about Bphone.

RE: CPU & RAM in a storage box

[Baruch Shpirer]

I am using a dual core machine with 1GB ram just for the OS even though its
not scratching the 50% usage
My raid controller is 3ware 9550SX-12LP 64-bit/133MHz PCI-X with 256 MB DDR2
400 memory with ECC protection supporting all raid types and with RISC
PowerPC cpu to provide real HW raid
This host is handling more then 8TB in Raid1 and Raid5 units easy and you
can leave hot spare drives and setup fast rebuild
Notifications both in snmp and mail will provide you alerts once a unit is
degraded or drive is giving errors (pre-fail)
I do recomment using real 64-bit interface and well... this card is old, you
can get newer and better similar cards.. so do the math

Subject: CPU & RAM in a storage box


Hi people,
I'm planning to add some big storage solution to my VPS business
 . I did some checking and calculated the costs, and
figured out that if I want to have a decent 12TB solution NAS box, it would
be best if I would roll my own. (12 TB before all the RAID stuff, after that
it would lot less). All other solutions are very expensive (example: IBM EXP
3000 costs here 6K nis without a single hard disk). 

I'm planning to use hardware based RAID card, minimal Linux distribution and
have some offers like iSCSI, NFS, CIFS - the usual suspects.


My question is: since I'll use hardware RAID card, which processor and how
much RAM should I put in such a machine? Xeon is overkill IIRC.

What do you suggest?

Thanks and Shana Tova

Re: Hacked server

[Baruch Shpirer]

1. run it behind a decent firewall ( even pf,iptables logs should give you
some idea about who's accessing your computer and using which service )

2. dont run anything with root

3. run chrooted env's if possible

4. reinstall using something more updated system and dont install anything
you dont need, skin it down

5. configure firewall and services ACL to allow remote access (SSH) or
service level (BIND) access from known ips/networks

6. honeypots and monitoring scripts

7. rootkits

8. IDS can come in handy to alert you on hazardus actions on the server
(snort?)

9. hide all information about application names and versions, same goes
for OS, search for OS hardening guides

RE: Linux NAS like Solution

[Baruch Shpirer]

Well... Even with the ppl I have read that had loss of data due to the
use of such
Systems, most of it comes from racklessness & no backup.

With hot swap and hot spare and I a nightly tape backup iam not that
afraid from loss
Of data.

SATA raid has a lot of problems, a lot of BAD microcodes for HD
controllers cause problems
With the raid controllers. There is a none official list of those HDs in
storage forums all Over. 
But still, I have read user comments for systems used in SMB With HW
controllers such as 
LSI MegaRAID  and 3Ware 8xxx which are working fine.

The lowest good NAS solution I found was 4.5K$ , how can you compare
that with a 1800$ solution with
350GB Neto ( After raid and snapshot deduction ) and I don't get
University discounts 
Snapshots
Hot spare
Hot swap
Power redundant

And you can even spend another 250-600$ for external disk enclosure so
it will be DAS like :)
( http://www.cwol.com/serial-ata/4-bay-hot-swap-raid-kit.htm )

You also have NAS os solutions like Darma OS if you dare to try

Or you can just compile your kernel and tune it for Network I/O and

Linux NAS like Solution

[Baruch Shpirer]

Title: Linux NAS like Solution






Hi,

I have been fiddling for the last 2 weeks with idea of saving my company more then 2000$ and making my own kind of NAS like solution via linux.

My considerations were highly to maintain the list of standard features NAS solution hold today including snapshots (lvm2) and hotswap disk rebuild.

Before I eleborate my findings if anyone has done this already I would be happy to hear his/hers ideas about this subject, I will have to close this solution

pretty soon.

Hotswap can be done both in SATA and SCSI

SATA would be the cheap and risky solution where as SCSI is more expensive and reliable

Most SATA raid solutions are Soft Silicon - Software based and use the system main cpu for the raid operations , there are some HW based like 3ware

Which seem on paper to be very good.

Next is can I trust the SATA Raid controller to do real reliable Raid 5 ? Cause going for SCSI comes to a price that I rather pay for NAS

Did anyone see or hear about a SATA Raid controller do hotswap in linux ?

Iam using gentoo and gentoo forum pretty much covered the software issues, I just need to know my HW fits.

Re: pam question

In sshd_conf

AllowUsers alex ref

Allow only certain users to have access via ssh to this machine.

AllowGroups wheel admin

Allow only certain group members to have access via ssh to this machine.
AllowGroups and AllowUsers have equivalent directives for denying access to
a machine. Not surprisingly they are called "DenyUsers" and "DenyGroups".

PasswordAuthentication yes

It is completely your choice what you want to do. It is more secure only to
allow access to machine from users with ssh-keys placed in the

I think you have some misunderstanding. The cable modem gets its IP (I think
it is internal for cable network, its in the 172.25.0.0 subnet) by DHCP. It
passes that address to dialing device (computer, router), also by DHCP. The
dialing device connect to the ISP gateway by L2TP (or
PPTP) creating a VPN (see also Geoff and Michael Sternberg mails).

My experience is different.

As mentioned above I chose Barak as the ISP. I intended to use a
switch-router (to connect 3/4 computers CONSTANTLY) so when I talked to the
cable guys I assured I get an Ethernet modem (It turned out that their modem
has both Ethernet and USB connections).

I had a router to play with, this one did not have L2TP protocol dialer, so
I called Barak and IMMEDIATELY they switched me to PPTP.
That did not help because when the router dialed with PPTP it needed a
static IP. I went and replaced it with switch-router that had L2TP (BTW,
there are at least 2 switch-routers under 300 NIS that have both L2TP and
PPTP dialers, and can get their IP by DHCP). I called Barak again and asked
to return me to the L2TP protocol, the support guy convinced me that PPTP is
better and helped me configure it (on a Windoz XP, just to be sure that it
works). After that I configured the router and now everything works fine.

I have some conclusions:
1. Call the support at about 8:00 in the morning, at that hour they
   are not busy and have all the time to be with you.
   NEVER, NEVER call in the evening if you can.
2. Ask/request from the support only what they SURLY knows (how to
   use PPTP from the Windows machine, not how to configure the router
   or a Mac/Linux)
3. Don't abandon your old connection to the Internet until the new one
   works (I had both Cable and phone ADSL for a week).
4. Sometimes (may be most of the time) It is cheaper to work around a
   problem than to solve it in its original framework (in this case -
   an external dialer for Linux instead of an internal software dialer,
   although I KNOW there are L2TP/PPTP dialers for Linux - just google
   for "PPTP linux" and "L2TP linux").
5. As Yehoram Ben-Yaacov said - "Don't waste time on getting mad on ...

I have noticed this weird fact too and switched back to ver 8.0

Also... I wanna recommend people who plan to buy laptops to run linux , some
of them are optimized to run XP and its not a joke
The "Designed to run run Windows XP" label means that even if you optimize
ur kernel for hours , the XP will still run faster ( unless you install
Office and and another 24 random applications and then its back to square

Subject: Redhat 9 slowness - continued

A few days ago, somebody complained about KDE being slower on Redhat 9 than
it was in earlier versions. I don't know if my experience is related, but it
confirms something bizarre is going on in Redhat 9.

I just switched from a Pentium 500Mhz running Redhat 8, to a Pentium 1500
running Redhat 9.

Remember how Hspell 0.5 took ages to run, and Hspell 0.6 is much much faster
to start up? Well, being in love with that fact ( ;)) I wanted to see just
how quickly it runs on my new fast machine. On my old machine, it took it
0.3 seconds to start up (hspell /dev/null). I expected it to take 0.1
seconds (CPU time) to start on the new computer, but... It still took 0.3
seconds!

I started cursing the fake CPU I probably have on the new machine, and the
bugs I probably have in Hspell, before I had an epiphany: what if some
dynamic-linking issues slowed hspell's running, and it wasn't hspell itself
which is slow?

So I recomiled hspell staticly (-static, i.e., without shared libraries) on
both machines. Lo and behold, Hspell now takes just 0.23 seconds on the old
machine, and 0.095 seconds on the new machine.

So, apparently, on Redhat 8 the dynamic linking added 21% to "hspell
/dev/null"'s static running time, while on Redhat 9, the dynamic linking
added 200% (!!!) to the running time of the static program. In absolute
terms, 0.2 extra CPU seconds were wasted on Redhat 9, and this is on my new
fast machine - on an old machine the added time would have been enormous.

But why is this happening? And why does it effect hspell, and not, say "cat
/dev/null"?

One thing I noticed is that when I do "ldd" to hspell (or cat, or anything),
I don't get /lib/i686/... like I got in Redhat 8 - instead I get some
/lib/tls/ What is that? setting LD_LIBRARY_PATH to /lib/i686 made hspell
very speedy again - 0.12 seconds - back to the acceptable 20% overhead for
dynamic linking.

Does anybody know what these "tls" version of the C library are? Why are
they so much slower to load? Or is there another explanation to the problems
I'm seeing?

Thanks for any insights,
Nadav.

But is that a Linux specific problem? Will another OS under the same

Since Intel's have been RISC chips under the hood ever since P2 (and
maybe 
before that), maybe it wasn't that harder.

I see a smc-ultra.c file in the kernel sources (drivers/net/) -- I think
you could simply compile the file from the kernel sources as a module
and insmod it. If the version supplied with RH8 kernel does not work
(since it's not the latest & greatest) try replacing the file in the
kernel sources with the one you downloaded and compile it as a module.

Well, as much as I know, all IBM notebooks are supported on Linux. Dell
- 
ditto. Sony is more problematic with some of their components (those
little 
cams, etc). Toshiba worked to me pretty well...

Most of the hardware will work for you. Remember to check which winmodem

you'll get (and you'll get winmodem) - lots of them have Linux support,
but 
some (like Motorola Winmodem) lacks support..

Good Luck,

I own an IBM Thinkpad T21. I installed Red Hat 7.3, Red Hat 8.0 & SuSE
8.0 on it -- all three installations were the easiest Linux
installations I did -- the only thing I had to do was press "next"
"next" "next" and that's it. All the hardware was auto-detected,
everything works great -- video, sound, DVD, network, modem. Everything.
The only thing I never did was make the Ultrabay work (the DVD is hot
swappable with a floppy drive, and I think a module needs to be
installed for the hot swapping to work correctly), but I think it's
supported, as IBM is a supporter of Linux. All Thinkpads come with
bundled Microsoft OSs (W2K/WinXP) and an installation CD containing the
OS and drivers.
