CentOS 4.4 blocking outbound connections?
Hello:
When I installed CentOS 4.4 (from the ServerCD) on my server, I told
it not to install a firewall and I disabled SELinux. The server is
a SuperMicro 5015P-TR.
I set up my own /etc/init.d/firewall with these rules:
#!/bin/sh
# Firewall script
#
# Source function library
. /etc/init.d/functions
RETVAL=0
# Some definitions (Will need to change ETH0_IP to match your configuration)

Centos 7 - iptables service failed to start
Hello all:
I did a fresh install of CentOS 7 on a new machine.
I wrote /usr/local/bin/firewall.stop to remove all the firewall rules.
It contains this code:
# Flush the rules
/usr/sbin/iptables -F
# Set the default policies to accept
/usr/sbin/iptables -P INPUT ACCEPT
/usr/sbin/iptables -P OUTPUT ACCEPT
/usr/sbin/iptables -P FORWARD ACCEPT

Outbound connections not using primary eth0 IP
Hello:
I have a machine running CentOS 5.2
I added two IP addresses to eth0 by copying
/etc/sysconfig/network-scripts/ifcfg-eth0
to
/etc/sysconfig/network-scripts/ifcfg-eth0:0
/etc/sysconfig/network-scripts/ifcfg-eth0:1
and changing the relevant IP info.
I am now seeing outbound connections
failing at my firewall from services like NTP, etc.
since they are now using a source address

Use Microsoft shared fax printer?

Is it possible to use Samba to send documents to
a Microsoft Shared Fax Printer?
How would I give it the phone number and other recipient
details that normally comes in the popup window when
I print to a shared fax printer from Windows?

Use 8GB RAM on Pentium D?
Hello:
I have a Supermicro SuperServer 5015P-TR.
It has a Pentium D and is running CentOS x86_64.
Can this machine use 8GB RAM?
I think it should because it is running a 64 bit
OS, but I am concerned because it is fundamentally
32 bit hardware.
Anyone have any experience in this area?
Thanks,
Neil

dumpe2fs and repquota not agreeing on block size
Hello:
I am trying to set up user quotas on my /var
partition to enforce limits on user's mailbox
sizes. The machine is running CentOS 5.
When I do this:
/sbin/dumpe2fs /dev/md2 | grep 'Block size'
Block size: 4096
That tells me the block size is 4k.
But, if I do:
repquota /var
It is telling me that one of my users is
currently using 10264 blocks. But, if I look

From LiveCD, mount hda1 gives resource busy
Hello:
I booted from the CentOS 4.4 CD.
I am trying to mount the partitions on the hard drive of
the physical machine (Fedora Core).
I did:
mkdir /mnt/hda1
chmod 755 /mnt/hda1
mount /dev/hda1 /mnt/hda1
I get back:
mount: /dev/hda1 already mounted or /mnt/hda1 busy
I checked with df. I don't see hda1 anywhere.
Any ideas what is wrong?

ip conntrack table full
xen-3.0.3-94.el5_4.2
2.6.18-164.6.1.el5xen
RHEL5.4 x86_64
I''ve got a dom0 that does nothing but have a DomU created. The DomU gets
plenty of load. Over time, the dom0''s ipconntrack table fills up but not
the DomU. Once it gets full I can restart iptables and it''s fine.
The strange thing is this only happens on hosts I have provided (hardware
and hosting) from one

Sendmail forwarding external email sent to root
Hello:
On a CentOS5 machine I set up for a client, in /etc/aliases,
I set root's mail to forward to my email address so I can
get notices from cron, etc.
Unfortunately, I am now getting a lot of spam which is
sent to root at theservername.com
How can I tell sendmail to not accept external email to
root?
I searched the Internet and found some horribly convoluted

How to know when files have finished FTPing?
Hello:
I have a server set up a CentOS 5 server for a client
to push files onto using FTP.
I have a cron job to process the files and
move them to another directory.
Sometimes, the cron job executes while the client
is still uploading a file (Some of them can be large)
and I get a partial file.
Is there a way to tell when a file has finished
uploading?

Install CentOS directly from usb drive?
Hello:
I followed the instructions here:
http://www.centos.org/docs/5/html/5.2/Installation_Guide/ch02s04s01.html
to put isolinux on a usb drive. When I boot from the usb drive,
the installer comes up and I can do a network install. I have
to say that is very impressive!
But, since I have a 4GB usb drive, I am thinking I can
load the rest of the installation onto the usb drive
so I do not have

tar with -N option still picking up old files
Hello:
I tried this command to tar up a set of data files
updated since yesterday (The data directory contains
multiple files with varying dates):
/bin/tar -z -c -N 2009-03-25 -f /tmp/test.tgz data
When I look at the content of the test.tgz file,
it looks like it copied the content of the entire
directory, not just the newer files.
I am on CentOS 5.
Any ideas?
Thanks,

How to run command as apache?

I have a subversion repository set up in
/usr/local/svn/MyProject.
For security, I have that directory set to
apache as the owner and group and all files

I need to run a svnsync command as the apache
user so it may write to the repository.

RTSP problems (and SNAT questions)
I am having problems making RTSP connections to a Windows Streaming Media
Server (ie "connecting to media...." but WMP never connects). There are no
error messages in /var/log/messages. It was suggested to me that SNAT might
perform better than MASQ in this respect.
I edited my shorewall/masq file as such:

or should it be?

how to know when files have finished ftping? --antairrestored
Just to chime in here, what I use is another file that is transferred
last. It can be zero sized. Just some name you look for and then delete
when you are done for next time. It doesn't matter how long that one
takes because you will know that the important files are already
transferred.

xen thinks guests exist but not show in list
Hello:
I tried to unsuccessfully install a guest on xen.
It failed when it tried to connect to the display
since I installed the OS without a graphical
environment.
When I do an xm list, I do not see the guest, but
if I try to do virt-install with the same guest name,
it tells me the domain already exists.
I tried xm delete on the domain but that also tells me
the domain does not exist.
