The current (1.7.x) cygwin ssh/rsync are OK, but there is a long history 
of earlier versions randomly hanging when rsync was running under sshd 
(i.e. started remotely).  It always worked with rsync configured as a 
standalone daemon or when executed from the windows side using ssh to a 
unix/linux target.

This used to be a problem when using backuppc to back up windows files 
with rsync.

[CentOS] necessary/unused rpm packages

2010-09-24 Thread Alice Anderson

Is there a way to identify if an rpm package is unused, or how much it is
used?

I would like to reduce my load time by removing unused packages in my
kickstart, but do not want to cause problems for users on active systems by
guessing which ones are not necessary (I load everything with kickstart
now).  If I could find the packages are not used I could start by excluding
them from a load and be fairly certain my users would not be impacted.

 If you want to keep it simple, I would not try to install at the same

 If you don't care much about control (in the free software sense) on
 your Java installation and just need the plugin, I guess you should go
 for the Sun RPM after uninstalling the base OpenJdk packages.

 Maybe some people on the list have other opinions / tips.

Well, other than that openjdk has not supplied/supported the java browser

 Have you tried using dos2unix against the downloaded file?

Thanks for jumping in, but I doubt that would resolve the issue.

First, the file (from java.com) is specifically for Linux RPM... or so
it's labeled on the website.  So I'd strongly doubt that would be the
problem.

Secondly (and more definitively), the script contains a sum command
(containing something like a CRC, I'm guessing) which checks its own
contents and then bails if it detects that it's been altered.  So unless
I want to do some pretty serious hacking, I can't alter the script.

It was funny, but it would have been more efficient to use tar over netcat

steady data stream to the network and wouldn't beat up on the file system as 
bad as rsync would.

Good read none the less. :)

[CentOS] Configuring BIND to answer to two domain names (four IP addresses)

On a CentOS 5 server, I am having a hard time configuring BIND to
answer to 4 IP addresses for 2 domain names.

Currently, I have four IP addresses, for sake of discussion they are:
1.1.1.1
1.1.1.2
1.1.1.3
1.1.1.4

Additionally, I have two domain names. For sake of discussion:
exampleA.com
exampleB.com

My goal is to have 1.1.1.1  1.1.1.2 as the nameservers for
exampleA.com, and 1.1.1.3  1.1.1.4 as the nameservers for
exampleB.com. Apache is running on this machine, and should of course
serve pages for the sites.

I think that I've got the apache configuration down, but the BIND
configuration is eluding me. I've read the following fine manual, but
I am still stuck:
http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-bind.html

Additionally, I have googled for how to configure bind for multiple
domain names and the like, but I see no mention of the IP addresses
configuration. Can I simply configure any IP address that the server
answers to as the nameservers? What am I missing?

Thank you in advance!

rpm -q --whatrequires will show what packages depend on a given package:

Unless you ask your users, you won't know what packages/programs they

There are some separately packaged components like deltacopy and cwrsync

  All you really need is the one dll and an executable, but it is pretty 
hard to get that from the cygwin installer.

 IMO, a windows system with Cygwin and Cygwin tools isn't really a

I'd call it 'enhanced' rather than crippled, since the point of using 
the tools is normally to make windows act like a more sensible unix box, 
but it is still sort of an ugly hybrid.

But in any case it is really hard to beat rsync and ssh for moving files 
around.

Have a read for the listen on directive for BIND which tells BIND what

You are making it much more complicated than necessary. I'd configure 
apache to use named virtual hosts and listen on all addresses (but you 
might want to tie https to specific addresses so you can tie connections 
to the right certificates), and bind to listen on all addresses and

So, then, the association of a FQDN with any particular IP address is

BIND has listen on directives as well, but if this is a single box 
configuration it's not necessarily required as it will listen on all interfaces.

As far as configuring the domains, well that's pretty simple. In your DNS 
records for each domain you would define NS records such as this

$TTL 1d
@   IN  SOA ns1.exampleA.com. hostmaster.exampleA.com. (
2010092401  ; PUT SEQUENCE NUMBER HERE 
(/MM/DAY/CHANGE #)
3600; Refresh every hour
600 ; Retry   - every ten minutes

[CentOS] grep contents of file on remote server

2010-09-24 Thread Tim Dunphy

Hello,

 I am attempting to grep the contents of a key file I have SCP'd to a
remote server. I am able to cat it:

[code]
[bluethu...@lbsd2:~]$:ssh r...@sum1 cat /root/id_rsa.pub
r...@lcent01.summitnjhome.com's password:
ssh-rsa 
B3NzaC1yc2EBIwAAAQEApnUSYyrM96qIBZKjwSNYycgeSv/FAKE-KEY-DATA--KEY-DATA-PWReyVuOn9Fb/uH/FAKE-KEY-DATA-+ttLzUELGrfn/n+FAKE-KEY-DATA-/FAKE-KEY-DATA-/FAKE-KEY-DATA-/FAKE-KEY-DATA-==
bluethu...@lbsd8-2.summitnjhome.com
[/code]

But I cannot cat / grep it in order to determine if this key is
already in the authorized_hosts file of the remote host.

[code]
[bluethu...@lbsd2:~]$:ssh r...@sum1 grep `cat /root/id_rsa.pub`
/root/.ssh/id_rsa.pub
r...@lcent01.summitnjhome.com's password:
/root/.ssh/id_rsa.pub:ssh-rsa ssh-rsa
B3NzaC1yc2EBIwAAAQEApnUSYyrM96qIBZKjwSNYycgeSv/FAKE-KEY-DATA--KEY-DATA-PWReyVuOn9Fb/uH/FAKE-KEY-DATA-+ttLzUELGrfn/n+FAKE-KEY-DATA-/FAKE-KEY-DATA-/FAKE-KEY-DATA-/FAKE-KEY-DATA-==
bluethu...@lbsd8-2.summitnjhome.com==: No such file or directory
grep: r...@bt-laptop: No such file or directory
[/code]

Ultimately, what I would like to do is script this in order to
automate this process:

[code]
#!/bin/sh
HOSTS=sum1 sum2 virt1 virt2 virt3 virt4 virt5 virt6 virt7
SSHDIR=~/.ssh
RSYNC=/usr/local/bin/rsync
KEYFILE=/home/bluethundr/.ssh/id_rsa.pub
CAT='/bin/cat'
GREP='/bin/grep'

for h in $HOSTS ; do
 scp $KEYFILE r...@$h:~/
 if   [ $? = 0 ]; then
  echo ;  echo ;  echo
  echo KEY TRANSFERRED TO $h
 else
   echo KEY Transfer To $h has FAILED
   exit 1
 fi
 ssh r...@$h $CAT /root/id_rsa.pub | $GREP -i /root/.ssh/authorized_keys
 if [ $? = 1 ]; then
  ssh r...@$h $CAT /root/id_rsa.pub  /root/.ssh/authorized_keys
  if   [ $? = 0 ]; then
  echo ;  echo ;  echo
  echo KEY APPENDED TO $h Authorized Hosts
 else
   echo KEY APPEND FAILED
 fi
 exit 1
fi
done
[/code]

This is what results from the above script:

[code]
[bluethu...@lbsd2:~/bin]$:./key-export.sh
r...@lcent01.summitnjhome.com's password:
id_rsa.pub
100%  417
0.4KB/s   00:00



KEY TRANSFERRED TO sum1
./key-export.sh: /bin/grep: not found
r...@lcent01.summitnjhome.com's password:
[/code]

And I'm pretty sure I have those variables set correctly in order to
execute those commands:

[code]
[bluethu...@lbsd2:~/bin]$:ssh r...@sum1
r...@lcent01.summitnjhome.com's password:

 So, then, the association of a FQDN with any particular IP address is
 only done in the domain name's control panel where the nameservers are

What's a control panel?  Bind is going to want a zone file for each 
domain where it is the primary nameserver and an A record for each host 
in that domain.  You may have some GUI tool to manage them.  But any 
instance of bind can be primary for any number of domains.  The

Yes, I actually do want it to listen on all addresses (only one NIC),
I don't know why I thought that it had to be explicitly configured.

As far as configuring the domains, well that's pretty simple. In your DNS
records for each
domain you would define NS records such as this

$TTL 1d
@ IN SOA ns1.exampleA.com. hostmaster.exampleA.com. (
2010092401 ; PUT SEQUENCE NUMBER HERE

IN NS ns2.exampleA.com.

ns1 IN A 1.1.1.1
ns2 IN A 1.1.1.2

www 1.1.1.4

Notice that the NS records point to ns1 and ns2.exampleA.com.

That is quite the point: I need the nameservers for exampleA.com and
exampleB.com to be different!

Notice the A records for www.example{A,B} which should match your
Apache instances if you are doing IP based hosting. If you are doing
name based hosting you *could* DNS round robin the requests.

If the nameservers are for specific addresses, and Apache serves based
on FQDN as opposed to based on address, then I think that Apache can
answer on all addresses.

Master and Secondary DNS configurations are defined in your
named.conf file. This doesn't matter in your necessarily for your

On the master

zone examplea.com {

Thanks. I will do another for exampleB.com as well, to keep them separate.

Put single quotes around the whole command you want to send to the

an update backed out the change in a couple of days.  So overall, I'd

 NO but be aware of what your doing as to not starve out Kernel Threads.
 Whats the kernel? It want hurt to give them priority either. Gbit and

 Example:

I know. The domain names _are_ in fact registered to different

Ok, we've got a new machine that's throwing ECC errors. I've gotten new
memory overnighted to me from the manufacturer, and replaced it, oops, not
that end of the bank, as their support told me, this end of the bank, as
the mobo manual I found online shows (Supermicro).

Still throwing errors. Ok, try to get more info Last week, I moved
/var/log/mcelog to /var/log/mcelog.1, and touched /var/log/mcelog. This
week, I tried running mcelog manually, and via /etc/cron.hourly/mcelog,
and get *nothing* at all. /var/log/message only screams that there are ECC

My take on things is that java and a lot of other things are really 
intended to work with several versions concurrently available - and 
perhaps running concurrently, where RPM wants to only have one and even 
with alternatives can only make one the default.  So any time you don't

[CentOS] Question on installing .run file

2010-09-24 Thread Jerry Geis

I am trying to automate the install of the ati driver package.
Basically all I do is hit return about 6 times and take all the defaults.

I tried to do this in a file that I then made executable with 744:

sh ati-driver-installer-10-8-x86.x86_64.run  EOF









EOF



but then it starts like its doing something but never does anything.

How might I automate such an install script. Again all I do is hit 
return 6 times
and accept all the defaults.

Thanks,

Jerry

Re: [CentOS] Configuring BIND to answer to two domain names (four IP addresses)

Thank you for all the help so far. To conclude:
I have one physical server that answers to the following IP addresses:
1.1.1.1
1.1.1.2
1.1.1.3
1.1.1.4

I need 1.1.1.1  1.1.1.2 to be the name servers for exampleA.com, and
1.1.1.3  1.1.1.4 to be the nameservers for exampleB.com. I have these
files:

# cat /etc/named.conf

options {
directory /etc;
pid-file /var/run/named/named.pid;
listen-on {
any;
};
};

zone . {
type hint;
file /etc/db.cache;
};

zone exampleA.com {
type master;
file /var/named/exampleA.com.hosts;
};
zone exampleB.com {
type master;
file /var/named/exampleB.com.hosts;
};



# cat /var/named/exampleA.com.hosts

$ORIGIN exampleA.com.

 Well yes, it does work OK. The point being though it's an

 I'm in the middle of moving now, but when the dust settles I
 will put my 'Installing Eclipse Helios 3.6.0 for PHP
 developers' on Centos 5.5 on my site. It covers Java,
 Xdebug, PDT, necessary repos, and starting to use the PDT
 plugin for debugging local and remote PHP scripts. I might
 even throw in a few screencasts. But that's another story
 getting OT now.

 My take on things is that java and a lot of other things are really
 intended to work with several versions concurrently available - and
 perhaps running concurrently, where RPM wants to only have one and even
 with alternatives can only make one the default.  So any time you don't
 want the defaults, you have some design decisions to make.  Still, I'm
 surprised that Sun and RH didn't make nice and have a publicly available
 RPM that puts things in RH-style places.

Granted. My workaround is to just point apps to the 
particular version of the JVM I want to use to run it, 
without trying to uninstall the default Java package. For 
example, running Eclipse with Sun's (Oracle's) Java:

To run Eclipse with an alternate Java runtime environment, 
the path to the Java virtual machine's binary must be 
identified.

Once the path to the virtual machine's binary has been 
identified, try running Eclipse with the following command:

  ./eclipse -vm /path/to/jre/bin/java

For an actual example, it might look something like the 
following:

./eclipse -vm /usr/lib/jvm/sun-java-6/bin/java
./eclipse -vm /opt/sun-jdk-1.6.0.02/bin/java

That is a good source to read up about bind configuration.

As a sidenote please be aware, that if someone directly queries your

answers. If you would need to prevent this for any reason you would need
a extended bind config design using views.

 Hello,
 
  I am attempting to grep the contents of a key file I have SCP'd to a

 But I cannot cat / grep it in order to determine if this key is
 already in the authorized_hosts file of the remote host.
 
 [code]
 [bluethu...@lbsd2:~]$:ssh r...@sum1 grep `cat /root/id_rsa.pub`
   ^^
Why the backticks around cat? The above evaluates the *local*
/root/id_rsa.pub, and then passes the result lines as arguments
(filenames) to grep on the remote machine, which of course makes no
sense...

What does the output of 

ssh r...@sum1 grep `hostname` /root/id_rsa.pub

display?  You don't need to cat the file to grep it.  Grep does
understand how to use fopen() all by itself, it does not need any help
from cat... :-)


 /root/.ssh/id_rsa.pub
 r...@lcent01.summitnjhome.com's password:
 /root/.ssh/id_rsa.pub:ssh-rsa ssh-rsa

 bluethu...@lbsd8-2.summitnjhome.com==: No such file or directory
 grep: r...@bt-laptop: No such file or directory
 [/code]
 
 Ultimately, what I would like to do is script this in order to
 automate this process:
 
 [code]
 #!/bin/sh
 HOSTS=sum1 sum2 virt1 virt2 virt3 virt4 virt5 virt6 virt7
 SSHDIR=~/.ssh
 RSYNC=/usr/local/bin/rsync
 KEYFILE=/home/bluethundr/.ssh/id_rsa.pub
 CAT='/bin/cat'
 GREP='/bin/grep'
 
 for h in $HOSTS ; do
  scp $KEYFILE r...@$h:~/
  if   [ $? = 0 ]; then
   echo ;  echo ;  echo
   echo KEY TRANSFERRED TO $h
  else
echo KEY Transfer To $h has FAILED
exit 1
  fi
  ssh r...@$h $CAT /root/id_rsa.pub | $GREP -i /root/.ssh/authorized_keys
  if [ $? = 1 ]; then
   ssh r...@$h $CAT /root/id_rsa.pub  /root/.ssh/authorized_keys
   if   [ $? = 0 ]; then
   echo ;  echo ;  echo
   echo KEY APPENDED TO $h Authorized Hosts
  else
echo KEY APPEND FAILED
  fi
  exit 1
 fi
 done
 [/code]
 
 This is what results from the above script:
 
 [code]
 [bluethu...@lbsd2:~/bin]$:./key-export.sh
 r...@lcent01.summitnjhome.com's password:
 id_rsa.pub
 100%  417

 KEY TRANSFERRED TO sum1
 ./key-export.sh: /bin/grep: not found
 r...@lcent01.summitnjhome.com's password:
 [/code]
 
 And I'm pretty sure I have those variables set correctly in order to
 execute those commands:

 So, then, the association of a FQDN with any particular IP address is

It is in bind's database (zone files).  In named.conf you associate
domains (all but the leftmost part of the FQDN) with zone files and
zone files map from hostnames (left-most part of the FQDN) to ip
addresses.

Fragment of named.conf:

zone deepsoft.com {
type master;
file deepsoft.com.zone;
// IP addresses of slave servers allowed to transfer
deepsoft.com
allow-transfer { any; };
};

zone wendellfullmoon.org {
type master;
file wendellfullmoon.org.zone;
// IP addresses of slave servers allowed to transfer
deepsoft.com
allow-transfer { any;};
};


In deepsoft.com.zone file are 'IN A' records that bind mumble.deepsoft.com to
some IP address and in wendellfullmoon.org.zone are 'IN A' records that
bind mumble.are 'IN A' records that bind mumble.wendellfullmoon.org to
some IP address.

 I know. The domain names _are_ in fact registered to different
 entities, though. The best hint is that the nameservers are on the
 same C block.

Which is still meaningless.  Some name servers serve *hundreds* of web
sites, many competing with each other.  Often large hosting companies
will serve hundreds of web sites, all with the *same* IP address and
many in competion with each other.  As a line of reasearch, this is
somewhat fruitless.  And it is doubtful anyone would really care --
anyone who is tech savey enough to know how use dig, whois, etc. knows
how BIND and Apache work and know all about virtual hosting, etc.

 many in competion with each other.  As a line of reasearch, this is
 somewhat fruitless.  And it is doubtful anyone would really care --
 anyone who is tech savey enough to know how use dig, whois, etc. knows
 how BIND and Apache work and know all about virtual hosting, etc.


Agreed 100%. But I'm not the only decision-maker and I'm learning in
the process anyway. This seems to be a rite-of-passage that I should
have gone through some time ago.

Thank you. That is quite what I had suspected, and of course the zone

 Thank you for all the help so far. To conclude:
 I have one physical server that answers to the following IP addresses:

 1.1.1.3
 1.1.1.4
 
 I need 1.1.1.1  1.1.1.2 to be the name servers for exampleA.com, and
 1.1.1.3  1.1.1.4 to be the nameservers for exampleB.com. I have these

You need:

ns2.exampleA.com. IN  A   1.1.1.2

And you might also consider:

www.exampleA.com. IN  A   1.1.1.1

With the rest of the IN A records for exampleA.com (and correspondingly

lacking MX records...  And if you have a MX record pointing to
mail.exampleA.com and/or mail.exampleB.com, you will need IN A records
for the mail. hosts as well.  Or you can use CNAME records.

 
 
  Broken! :)

I think that's reasonable - but note that from the rest of the world's

from the upstream DNS that would have been added when you registered the 
servers as primary for the domain.  For anything else, the query gets

I did see mention of the term glue records earlier while googling,
only now am I googling it...

Oh, it looks like I may need to set those too. When I configured
ns1.exampleA.com  ns2.exampleA.com in the registrar's control panel,
I did enter the 1.1.1.1  1.1.1.2 addresses. Should that be enough?

They are the same.  The $ORIGIN is normally appended to names, but not 
when it has a trailing '.' (in which case you include it yourself).

When you have an $ORIGIN statement, it defines a suffix to automatically
add to any name that does not end in a '.'.  You can do either,
depending on how gratiously verbose you want to be.  Of course, being
verbose sort of defeats the whole point of the $ORIGIN statement...
