I would be wary of letting the apache user control iptables...
Better have another independent script to read the list of IPs file, filter it, 
and then call iptables.

[CentOS] Does anyone know if I can reconfigure a PERC H700 without rebooting?

2011-08-22 Thread Kevin Thorpe 
Hi all,
 I have a server which is really difficult to restart because
of usage requirements
and the fact that it's in a co-lo rack so miles away. I've added a
couple of drives which
I'd like to bring up and add to LVM but the config I know is in the
PERC BIOS and
requires a reboot.

Can the config be changed in the openmanage suite and if so can someone point me
in the right direction?

thanks

I assume that the hard drives are hot pluggable, but the point is to add 
them to the Perc Raid volume group. I doubt it is possible without a 
reboot, but you it should be asked to Linux-PowerEdge mailing list...

Well there certainly might be better ways, but if iotop for example indicates a

[CentOS] Not receiving root mail

2011-08-22 Thread Anne Wilson 
Although I have the alias defined in /etc/aliases and /etc/postfix/aliases, 
I'm not receiving root mail.  Following the previous thread about unreceived 
logwatch mail, I tested with a manual run of logwatch, and found that my ISP 
is rejecting the mail because it is seeing an envelope carrying my local 
address.  My suspicion is that the mail is going out via sendmail instead of 
postfix-sendmail.  IIRC there used to be system-switch-mail or a similarly 
named package.  I can't find any such package - and can't remember which file 
it edited.  Can someone please point me to that file?

It looks like your outgoing mail from your local user(s) needs to be

Once your email is out on the Internet is needs a genuine Internet email
address. xxx.lan is known only to your internal system and it is not an
Internet email address.

Care to show the headers of your outgoing email ? (cover-up the bits you
want to keep private)

I think Barry has it right here.

Also, if you're using postfix, you should "yum remove sendmail" to
avoid any possible conflicts.  There's no reason to have sendmail,
postfix implements its own 'sendmail' command.

If you're running postfix, you might want to also edit /etc/aliases.
The last line or so has a commented line, person who should get root's
mail.  (The name is marc, probably the person who first wrote it.)

After changing that, run newaliases /etc/alias to rebuild the
/etc/alias.db.

To answer your other question, alternatives is the command you asked
about in an earlier post

alternatives  --config mta

This will show you if you're using postfix or sendmail.

Not sure where I can find the outgoing mail but I can give more info that might 
help.

It's a long story, but probably relevant, so -

We first set up a family LAN around 12 years ago, and called it xxx.net.  
Eventually I realised that xxx.net was actually a TLD name, so not a good 
idea.  Actually I now own both xxx.org and xxx.net, but I decided that with 
this install I'd correct what had long been our practice.

On the new CentOS install I set the server name to borg.xxx.lan.  I then 
changed every reference to xxx.net in /etc/hosts, and set about changing the 
Postfix config files.  (I know now that it is using postfix.sendmail,)  
Somewhere 
I either have some other file still pointing to the old name, or, more likely, 
postfix is still using it somewhere.

I have been careful to re-map transports and restart postfix after any changes 
to the config files.  The following from maillog may shed some light as to 
where 
the problem lies:

The old transport read:

*   smtp:[mailhost.zen.co.uk]
.*  smtp:[mailhost.zen.co.uk]

Those lines have been left and 

xxx.lan local:
.xxx.lanlocal:

added in.

A more likely suspect, I think, is main.cf - the relevant lines in the old one 
being 

mydestination = $myhostname, localhost.$mydomain, $mydomain, xxx.lan
myhostname = borg.xxx.net
mydomain = xxx.net
myorigin = $mydomain
masquerade_domains = $mydomain
#masquerade_domains = |borg.xxx.net
mynetworks = 192.168.0.0/24,127.0.0.0/8

and the latest version (after many thrashing edits)


mydestination = $myhostname, localhost.$mydomain, $mydomain, xxx.lan
myhostname = borg
mydomain = xxx.org
myorigin = $mydomain
# masquerade_domains = $mydomain
mynetworks = 192.168.0.0/24,127.0.0.0/8

Sorry this was so long, but it seemed important to give you as much info as I 
could.

Thank you peter for the input...I don't think its the motherboard as I
have 5 of these boxes and they all experiencing the same problem
(running the latest bios). I tried switching the RAM around and did
manual timing at 667 in the BIOS, hope this fixes the problem. Kingston
won't be too happy if I tell them that there memory is not working in my
systems specially when we talking about 512GB of memory. Let's see what
happens, I will report back as I monitor this situation.

I think you also need to rewrite your envelop address.

I had the same problem years ago, so the way to solve it has probably
changed, hopefully not too much :

- edit (create if necessary) /etc/postfix/sender_cannonical
a...@borg.xxx.lan  some.addr...@some.real.server.for.the.bounces

- edit main.cf :
sender_canonical_maps = hash:/etc/postfix/sender_cannonical

- rehash /etc/postfix/sender_cannonical and reload postfix

Good luck,

Actually, the "main suspect" is the program or person that is sending out 
mail with an unqualified sender, e.g. just "user". Change it to a 
qualified sender (e.g. with a resolvable FQDN).

With sendmail you can set 'MASQUERADE_AS' in sendmail.mc to the FQDN 
that you would like to have added to unqualified senders.  And if you 
want mail from root to be included in this treatment you have to change 
the default 'EXPOSED_USER' setting which assumes that root mail will be 
kept local or sent to an internal hub where you will want to see the 
real sending host.

Yes. d/l the LSI MegaRAID software, and you can do pretty much the same

[CentOS] Mount --bind source / mountpoint out of sync

2011-08-22 Thread Trey Dockendorf 
I have a shared web server that users can SSH / SFTP into to access their
web content.  Each users home directory is in a change root, and I use
"mount -o bind" to put their respective webpage's document root into their
home directory.  Recently I was made aware that the contents of the mount's
source are not the same as the mount point's, which I don't see how that is
possible.

The file system is 3 virtual disks...each part of the same volume group.  I
have three LVMs, "/" , "/chroot" , and "/var".

Here's the entry in /etc/fstab...

/var/www/example.com   /chroot/home/user1/example.com   none
 defaults,bind   0   0

The mount is active, yet running a recursive diff between "/var/www/
example.com" and "/chroot/home/user1/example.com" shows numerous
differences.

Here's "mount" output
--
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sda1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
/dev/mapper/VolGroup00-lv_chroot on /chroot type ext3 (rw)
/var/www/example.com on /chroot/home/user1/example.com type none (rw,bind)
/dev/mapper/VolGroup00-lv_var on /var type ext3 (rw)


I honestly have no idea how this is possible.  Is using "mount -o bind" not
the best method to give a chrooted user access to a single directory outside
the chroot?  Would it be better to leave the web root in the chroot and have
Apache (outside chroot) reference that location?

Thanks
- Trey

It is obvious you run both Sendmail and Postfix, ending in trouble. The
sendmail binary (which is a symlink) still points to Sendmail, though you
seem to have configured Postfix as you system's MTA.

What kind of differences does the diff show? Missing files, corruption in 
the files, do modifications that you make in one directory not show up in 
the other?

This is a bit of a shot in the dark perhaps but in which order was the
bind mount and httpd restarted last happen? Is it possible that httpd
has a file handle to the inode where the underlying directory for the
place being mounted too rather than the directory that is being bound?
If you unmount the binding do you see any files there? Which location
has the most recent files? These are the questions that first time to
my mind for troubleshooting purposes.

@Dennis,

The differences were basically any changes made by the user , but for how
long I'm unsure.  It was reported today but that could be that he wasn't
using the files until today.  The differences between the the mount point
and source were a wide range of things from small file changes or entire
directories...nothing corrupt, but it seemed like there was a point in which
changes made to the mount point (within the chroot) no longer appeared at
the mount source.

@James

When I unmounted the directory there were indeed files in the mount point's
folder.  It seemed that the mount point (in chroot) was the only thing
effected by changes, not the source (out of chroot).  I don't understand the
question about httpd and the file handle inode.  Could you explain?

What was strange (and maybe this is expected while still mounted), rsync did
not have an effect when run in an attempt to update the source with the
mount point.  I ended up having to restore from last night's backup to
resolve this, but am extremely puzzled as to why this happened, and a bit
worried as this was going to be my new method for allowing access to hosted
web services via SSH / SFTP.

Thanks
- Trey

[CentOS] cant login remotely proftpd

2011-08-22 Thread Tim Dunphy 
Hello list!

 Well I have delved back into my proftpd config in the hopes of resolving my 
issues and having a working server. :)

  I believe I have the passive mode issue that I was expereriencing last time 
mostly worked out. But there are still a couple of things going on with this 
config that I was hoping to run by you in hopes of finding a solution. 

  If I execute an ftp session on localhost from the ftp server itself, I can 
log in and the ftp client does not complain when I try to list a directory. 

[root@VIRTCENT29:~] #/usr/bin/ftp localhost
Connected to localhost (127.0.0.1).
220 FTP Server ready.
Name (localhost:root): bluethundr
331 Password required for bluethundr
Password:
230 User bluethundr logged in
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> ls
227 Entering Passive Mode (127,0,0,1,183,201).
150 Opening ASCII mode data connection for file list
226 Transfer complete
ftp> quit
221 Goodbye.


However if I log into the external address of the FTP server the login fails.

Name (snjh.net:root): bluethundr
331 Password required for bluethundr
Password:
530 Login incorrect.
Login failed.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> quit
221 Goodbye.

There is no activity in the logs when I log in remotely. I dont believe it to 
be a firewall issue because iptables on the local ftp server has been disabled 
by stopping the service and the router has been configured to open port 21 and 
the passive ports I have selected (6-65535).

I have verified that port 21 is open with nmap:

[root@VIRTCENT29:~] #nmap -p 21 snjh.net

Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2011-08-22 20:39 EDT
Interesting ports on pool-71-187-203-194.nwrknj.fios.verizon.net 
(71.187.203.194):
PORT   STATE SERVICE
21/tcp open  ftp

Nmap finished: 1 IP address (1 host up) scanned in 0.371 seconds


And it looks like the system is prompting for a password, but authentication 
fails. But why it only fails when I attempt this remotely and it works when I 
do this locally is a bit puzzling. 


And if I mount an NFS directory login fails on localhost too:

[root@VIRTCENT29:~] #mount nas2:/mnt/home /home

[root@VIRTCENT29:~] #/usr/bin/ftp localhost
Connected to localhost (127.0.0.1).
220 FTP Server ready.
Name (localhost:root): bluethundr
331 Password required for bluethundr
Password:
530 Login incorrect.
Login failed.
421 Service not available, remote server has closed connection
ftp>

This is what happens in the extended log when I have the NFS partition mounted:


[root@VIRTCENT29:~] #tail -f /var/log/proftpd/pftpd-extended.log
:::127.0.0.1 UNKNOWN nobody [22/Aug/2011:20:42:49 -0400] "USER bluethundr" 
331 -


And if I unmount the NFS partition, I am able to log in again:

[root@VIRTCENT29:~] #umount /home


[root@VIRTCENT29:~] #/usr/bin/ftp localhost
Connected to localhost (127.0.0.1).
220 FTP Server ready.

ftp> ls
227 Entering Passive Mode (127,0,0,1,205,137).

And this is what happens in the logs once I am able to log in again

[root@VIRTCENT29:~] #tail -f /var/log/proftpd/pftpd-extended.log
:::127.0.0.1 UNKNOWN nobody [22/Aug/2011:20:45:31 -0400] "USER bluethundr"

:::127.0.0.1 UNKNOWN bluethundr [22/Aug/2011:19:45:37 -0500] "QUIT" 221 -



Im including my config below.. I was hoping someone could provide a clue as to 
why this is hapening! thank you very much in advance and best regards!

Thanks - that's what I was looking for.

alternatives --display mta
mta - status is manual.
link currently points to /usr/sbin/sendmail.postfix
/usr/sbin/sendmail.postfix - priority 30

slave mta-sendmailman: /usr/share/man/man8/sendmail.sendmail.8.gz
Current `best' version is /usr/sbin/sendmail.sendmail.

I assume this means that sendmail.postfix will be used as preference,
but that last line confuses me.  Is it safe to remove sendmail now, or
does that imply that some things will still need it?
