Have you tried /sbin/grub2-install?  It's installed by grub2-tools.

I corrected that by changing inet_interfaces to localhost from all in

When I try to log in with Roundcube, it just times out.

I'm stuck!

[CentOS] Installing an SSL Cert

[ML]

HI All,

I am considering buying this: 

http://www.godaddy.com/Compare/gdcompare_ssl.aspx?isc=sslqgo003a

Since I have a domain that will be collecting data and processing payments. 

Where can I find instructions on how to install the certificate?

Do I have to run another domain or sub domain for the store? Or can I just run 
the whole domain on https?

Thanks,

[CentOS] SSH slow

Hi All,

All of my systems are running 5.4 x64. The are all AMD x64 processors with at 
least 2gb of RAM in each.

I am running SSH on a non standard port.

When I SSH into ANY of my systems, I get prompted for my password right away, 
but after entering, it takes 30+ seconds to get logged in and get a prompt so I 
can work.

I dont quite know what to look for here

Does anyone have thoughts?

OK, I have a comcast modem as pass through.

I have a firewall and behind it is the mysql server (public IP)

I have an Apple Time Capsule that is NOT behind the firewall, but does have a 
public IP on the same network as the firewall and MySQL Server. The Time 
Capsule nats and give clients behind it a private IP.

[CentOS] Frustrations with MySQL loss, tcpdump, netstat, etc

[ML]

Hi All,

Hi All,

MySQL 5.0.77 on CentOS 5.4

MySQL is running, my Wordpress stuff is working, but I cannot connect to the 
server from my house. This server is in my house, however, but on a public IP, 
behind a firewall, etc.

I checked my hardware firewall (a dedicated UnTangle system) and that is 
successfully allowing the passage. I know this because the firewall shows:

2009-12-22 6:29:41 am passed :35606 :3306

I checked the firewall (system-config-securitylevel-tui) on the server and that 
has 3306:tcp allowed. 

When I try to connect I get an error (4) which when I google says: "Interrupted 
System call"
I have tried using the MySQL Workbench and other client software.

If I look in /var/log/mysqld.log I dont see anything but the fact the server 
started. 

I tried stopping mysql with /etc/init.d/mysqld stop

Then starting with mysqld_safe --init-file=/tmp/code.txt &

Where code.txt contains:

UPDATE mysql.user SET Password=PASSWORD('mypassword') WHERE User='root';
GRANT ALL ON mysql.* to 'root'@'127.0.0.1';
GRANT ALL ON mysql.* TO 'root'@'localhost';
GRANT ALL ON mysql.* TO 'root'@'my home IP';
FLUSH PRIVILEGES;
commit;

and I still cannot connect. But the database starts and this code executes 
because If I go to the console and run /usr/bin/mysql -u root -p and use this 
password from the update statement that password gets me in.

So, on my server I run tcpdump host  and I dont think I see anything 
where 3306 is coming through. 

if I run a test MySQL connection from the MySQL Workbench and they run netstat 
on my server
and I dont see a entry where 3306 is used in what netstat is dumping.

What am I doing wrong? What can I check for? I am stumped!

Well I thought a yum upgrade would get a php update if it was available, but 
there was nothing, so I tried a normal yum upgrade php as it would be nice to 
get to php 5.3.

So must be the mirror I am using doesn't have an upgraded package.

[CentOS] Zimbra help?

[ML]

Hi All,

Is anyone versed in Zimbra? I have most things working except some MTA issue. I 
tried posting on the Zimbra forums after reading the docs, but my post was 
labeled as SPAM and the moderators have not replied to my private message to 
get my post reviewed. Who uses this type of method for getting help anyway? 
Aren't the days of Bulletin Board BBS's gone?

Anyway...

I installed ZCS for the first time today. Most things are running except I 
cannot send or receive mail. I get MTA errors. I assume that it is not running. 
When I send I get unable to connect to MTA.

How do I diagnose the issue?

[CentOS] Zimbra Help

[ML]

I am playing around with Zimbra.

For the install, I selected the Fedora 11 version for x64.

I am running: Linux 2.6.18-164.el5 #1 SMP Thu Sep 3 03:28:30 EDT 2009 x86_64 
x86_64 x86_64 GNU/Linux

When I install I get an error: 

This platform is CentOS5_64
Packages found: F11_64
This may or may not work.

Installation can not continue without manual override.
You can override this safety check with ./install.sh --platform-override

I am not well versed enough to know if I can do the override install and things 
will be fine. 

Did I download the wrong version from:

People went back and forth on the list saying that if a hardware

solution.

It seems that the installer wont let you create two RAID1 with the  
same mount-pount and it looks like you have to specify one. I dont see  
how to do this and I dont know how to make a custom installer for this.

[CentOS] RAID 10 on Install?

[ML]

Hi All,

How can I RAID 10 on install? (the names myRAID1 and myRAID2 are just  
for example purposes)

I select a custom layout

/dev/sda, sdb, sdc, sdd are listed...

I create a partition of Software RAID on each of sda, sdb, sdc, sdd

Create a swap partition on sda?

Click RAID and take sda and sdc and RAID 1 to myRAID1

Click RAID and take sdb and sdd and RAID 1 to myRAID2

Click RAID and take myRAID1 and myRAID2 and RAID0 to MYRAID

This leads me down to swap. If I create swap on sda, then dont sdb,  
sdc, sdd then all have unused space of the size of swap on sda?

What is the rule of thumb for Swap these days. Back a long time ago it  
was double the RAM in the machine.but that was a long time ago,  
what is best now?

Thanks for the chat!

No it makes sense.

Neil,
Can you explain how RAID 10 would work with 4 x 1tb drives?

Should I just get 2 x 2tb drives and mirror?

I probably dont need 4 x 1tb drives to start, maybe even 2 x 2tb. I  
can't image this growing faster than I can get money to add more

[CentOS] Infrastructure HELP!

[ML]

Hi Everyone,

I started a social networking site and I am getting ready to go live  
next week. I have limited fund as I am not funded yet (although  
hopefully soon).

I have an extra Mac Pro (I know, how can I possibly call a Mac Pro  
dual 2.8 quad core with 16gb RAM extra). So Mac Pro quad Core, 16gb  
RAM, 4 x 1tb RAID level Seagate drives. I was going to load CentOS 5.4  
on it, web, mysql etc, etc. This is really the only box I have that  
would handle the site it it takes off and then I would need to add  
more hardware and most hosting to RackSpace or something.

My question is about initial setup. The 4 x 1TB drives. How to set  
this up for I have some protection?

RAID 0+1? (striped + mirrored) I would end up with 2TB useable space.

RAID 5? so what one is a hot spare? 3TB useable space?

What about striping the 4 1TB and mirroring that to a 4 x 1tb External  
drive enclosure?

I want to be sure the data is protected, but machine resources and  
money are limited.

Thoughts are appreciated!

My firewall is set to allow 2977.

Just for shits I changed this to 29770

I ran: system-config-securitylevel-tui and customized and added  
29770:tcp to other ports

I then: nano /etc/ssh/ssh_config and said Port 29770

So that I have:
Host *
Port 29770
Protocol 2

I then did: service sshd restart

and I still get connection refused. Comment out Port 29770 and all is  
well again.

[CentOS] Still Confused about Firewalling

[ML]

Hi All,

Sorry, I am still confused about implementing a firewall without  
having my ISP static route all of my traffic to my public IP's to a  
single public IP.

So before when I have done this for work all traffic has been  
statically routed.

Now I have a comcast modem and it is 'pass through' so traffic for all  
my 13 IP's is allowed and I have to decide what to do.

So I am looking at Vyatta or UnTangle. I have a machine with 3 NIC'e  
in it. I think one would be In, DMZ and last private.

What happens? I have one cable from my comcast gateway to my firewalls  
NIC, but how does it answer for all IP's that I have so i can evaluate  
the request incoming to a rule set and decide if allowed or denied?

I am missing something fundamental!  Can anyone help this click in my  
head? Without statically routing my traffic I dont get it.

Say a request comes to my webserver 172.13.167.xxx on port 80, but my  
firewall's IP for the card is 172.13.167.zzz how does it answer for  
172.13.167.xxx?

When eth0 is alive, I see that it tells me my name is 
173-13-167-209-sfba.hfc.comcastbusiness.net 
  since I am using a comcast DNS Server.

So if I setup my own internal caching name server for 173.13.167.209  
then I have a third name or can I just use the GoDaddy DNS entry I  
gave it? Do I then set my systems to use my local name server for  
their information and not Comcast? How does that effect internet  
browsing where I dont have entries for google.com, etc in my local  
name server?

Lastly, If I have two NICS (one is 173.13.167.209 and second private  
internal IP) For my local name server I would have two entries, one  
for public and one for the private card so I can do something like  
'inhouse.local' and get intranet or ssh inhouse.local, etc correct?

I see that Paul Heinlin put out a DNS tutorial here: 
http://www.madboa.com/geek/soho-bind/
Paul, I appreciate this!

[CentOS] Linux CD Stores

[ML]

HI All,

It seems that the days of ordering burned CD's of distros has faded.  
People just have fast internet now. I recall a number of times that I  
ordered Slackware CD's or others because it was just easier than  
downloading and burning myself. I am actually planning on ordering  
CentOS 5.4 media when available to support the project.

Does anyone think these store make any money? (Linux CD Mall, Linux CD  
Shop, Linux Central...etc)

I see a number of them (like Mad Tux) dont exist anymore.

Wouldn't someone selling a set for a few dollars plus shipping clean up?

Opinions, please.

Yup did that

then: route ass default gw 172.16.254.1

I get: Network is unreachable

I can ping 172.16.254.1 from my Mac though.

[CentOS] RSync Issues

Hi All,

Rsyncing to a USB drive. I am in single user mode.

I am doing:

rsync -avx --stats --progress --ignore-existing --exclude 'home/backup/

But I dont see if ignoring existing. A previous rsync stalled and now  
it seems to be copying them again rather than ignoring them.

Does anyone have thoughts?

Hi All,

I was trouble shooting why an rsync was taking over a day.

I found the problem to be in in a directory in /home that has CVS  
backups in it.

I browsed to find out that there are 7 .tar.gz archives that are each  
about

1199943181 in size.

So that is over 11gb each? If I am doing the math in my head right

No wonder why this is taking forever to rsync to a USB drive. It was  
only on the second of 7 and I started it at 2pm yesterday and it was  
not done/going this morning

[CentOS] More about firewalling

[ML]

Hi All,

So before when I used PIX's for my employer, our traffic was  
statically routed to one IP and then the firewall decided if allowed/ 
denied and passed it on or dropped it.

I have a Comcast business circuit with 13 IP's. The gateway device  
they provide is a 'pass through' device. They sent traffic for all 13  
IP's my way. It just allows traffic through. So if I put in a device  
to firewall (like Ipcop or Vyatta or something) in front, say it has 3  
NICS, how do I do that?

If the Firewall has IP A and Traffic for IP B comes in how would IP A  
answer and decide if the traffic to IP B belonged?  Without statically  
routing I am confused on how to accomplish this?

How fast does this device need to be?

Best,

OK, I booted into single user mode and when starting up I see that it  
says /dev/VolGroup00/LogVol00 has two volumes.

it the checks /boot and I am at sh-3.00#

in /etc/fstab I see:
/dev/VolGroup00-LogVol00/   ext3[snip]
Label=/boot /boot   ext3 [snip]
none/dev/pts
none/dev/shm
none/proc
none/sys
/dev/VolGroup00-LogVol01swap
/dev/hda/media/cdrecorder
/dev/sdb1   /media/usbdisk

So if I understand this I can just go after / doing rsync -av?

Thank you for the help thus far!

So after booting to the CentOS 5.3 LiveCD, I can get to '/mnt/ 
VolGroup00-LogVol00'

doing a: 'sudo du -h --summarize /mnt/VolGroup00-LogVol00' I get: 28GB  
used.

So can I 'rsync -av /mnt/VolGroup00-LogVol00/. /mnt/disc/sda1/.'
(sda1 is the 500GB USB Drive that I am wanting to put the data on.)

I booted to a the CentOS 5.23 LiveCD.

Yes, it looks like LVM is running because I do have VolGroup00- 
LogVol00 in Local Logical Volumes on the desktop.

Can I get the whole VolGroup00 at once, I see an entry in /etc/fstab  
for /dev/VolGroup00/LogVol00?

If not, how do I know what the partitions are that I need to go after  
on this old drive after being booted to a LiveCD. I chose a LiveCD  
because without it the machine takes an hour to boot die to DNS issues  
and time-outs since moving it to my location (and the original  
location does not exist either)

[CentOS] [Slightly OT] Data Preservation

[ML]

HI All,

So I have 5 1U servers (running Windows) that have Ultra 320 SCSI  
Drives in them.

The owner of these boxes wants the drives captured in their current  
states to .iso or .cdr or something where if the need arises the data  
can be viewed, used again, etc.

So what is the best approach? Boot from a Live CD, hook up a USB  
external HD and do what? Can I create a .iso or .cdr (or some other  
portable format) and have it created on the external USB?

Thoughts on this process would be appreciated.

[CentOS] Build a Firewall (Can I learn to do this...)

[ML]

Hi All,

I have a home business circuit and I am gearing up to host my business  
affairs in my place. I have Comcast and 13 static IP's.

I have an extra PIII 1U, 2 9gb SCSI, 1gb RAMm dual NICS.

So I am wanting to build a firewall to front end my traffic. Assign  
one of my statics to it and have Comcast statically route my traffic  
to this IP. Then when traffic comes have it decide if it is allowed or  
not and if allowed pass it to the right server based upon the rules.

I used to work with PIX 525's so I have knowledge, I just dont quite  
know how to do this with CentOS and such.

Can anyone offer advice?
