similar to: iptables help request

I apologize if this has been asked and answered, but I googled and attempted things for several hours today without success. I have a freshly installed CentOS 7 system that I'd like to disable the firewall and all iptables rules. Basically the equivalent of doing iptables -F In a nutshell I've tried the following commands, in many different ways and orders, but when the system

Wondering if anyone is willing to give me a little assistance with some firewall rules. I think what I'm looking for is fairly simple, and I've been trying to use webmin's firewall module without success. I have a web server that I'd like to open up port 80 and forward a specific port for a select number of allowed ips. That's it. Everything else is dropped. allow: port 80

Hi. I have some new 64bit Windows 2008 R2 domU''s running on SLES11/xen_3.4.2. What is everyone using to get 1gb network performance on win2k8? I''ve used GPLPV on win2k3, but I see you have to sign the drivers yourself for 64bit. Maybe that process isn''t difficult, I only glance at the link from gplpv''s page. What is everyone using? GPLPV is about the only

I had an issue late yesterday where some windows domU''s were down. The person who "owns" those domUs let windows updates install and then restart, which they failed to restart. When I tried to manually restart them I was getting can''t allocate memory errors. In the past I''ve had can''t allocate memory errors when trying to bring up a new domU.

I have xen 3.04 running on SLES10SP1. It''s working great, but I''m wondering if I have some memory issues with dom0. I have 7 domU''s, 1 is win2k, the other 6 are win2k3. I''ve had a lot of machines up and down with a reboot of dom0 in quite a while. I''m wondering if dom0 has not given up memory during the process. I added 5 win2k3 domU''s today.

I'm trying to use procmail and I'm having trouble getting it to set some headers. I have one mailing list that sets ?Newsgroups: in the header and I want to remove it. I have the following test recipe: :0 * ^Subject:.*\<testing * ^(Mime-Version:|Content-) | formail -IMime-Version: -IContent- If I understand it correctly, it should remove the Mime-Verion and Content headers. The

Sorry for the off topic, but don't a better resource. I'm not great at scripting, but need a quick script to modify a file. I have a long file that has lines like this: some text some text2 CN=DATA.OU=XYZ.O=CO some text3 some text4 And this repeats, but XYZ changes. "DATA" is always called data. (it's being renamed basically) I need to change the middle line but leave

I was looking at my maillog and it looks like someone is trying to get into my pop3 server.

I need to enable some access to the httpd logs over ftp so they can be analyzed by another application to get a report. I used to do this on Windows NT before replacing the server with CentOS. Thanks to help from another thread I have an ftp server enabled on the web server. I thought the easiest thing to do would be to create an id for the application to connect with, then provide a symlink to

Looking for help kind of in a hurry. I've been searching google but not finding any options. Is there any way to fix missing /dev paths to luns without rebooting? For example, see the output from lsscsi below. The only way I know to fix this is with a reboot, but I REALLY Need to avoid that if possible.

I'm not sure why this started, but apparently I'm having a DNS problem. Yesterday mail started bouncing with this error: 450 Unable to find obrien-pifer.com I think the messages eventually get delivered, but not sure. I guess I'll see if this one makes the list. I checked my domain using http://www.checkdns.net/ and it gives me a couple warnings. One is that there's no MX

I have a USB disk connected to a Poweredge server. The USB Disk is a Mad Dog MegaVault with a 160GB drive installed. It's all working fine, but the external LED on the unit is not working. I'm currently running a script (yum-pull) for setting up a yum mirror and it sits for long periods of time seemingly doing nothing. I started the script this morning at 6:20 for my FC4 yum mirror and

I have a 64bit centos 5.2 system. My router supports sending logs to a syslog server, so I was hoping to send them to my centos box so they are easier to keep an eye on. I've been googling for howto's etc, but I didn't think syslog would be that difficult. Do I need to use syslog-ng or can I use the syslog that's installed with centos 5.2? Any suggestions or guidance? Thanks,

I''m running xen on SLES10SP2. It''s been much more stable than SP1, but I still occasionally have issues. For example, one of my servers (8 CPU/32GB RAM) has five sles pv domUs and five fully virtualized windows 2k3 domUs. It had been up for almost 60 days. Yesterday afternoon one of the sles domU''s stopped responding. I went to check on it and I couldn''t using

Curious if any one has looked at or done a trial of Novell''s PlateSpin Orchestrate? Just watched their webcast presentation on it and it looks interesting.

I have a server that is running iptables. I'm trying to allow vsftpd in and have the following rules. I can connect to it, but when I try to do a listing it says "Entering Passive Mode" but doesn't do anything. Any suggestions? Thanks, James # define it -N FTP_INP -A INPUT -p tcp --syn --sport 1024: --dport 21 -m state --state NEW -j FTP_INP # rules -A FTP_INP -j ACCEPT #

I have a sles10 domU running on a sles11 dom0. xen is version 3.4. We''re trying to pass through a scsi card to the domU. We assign the domU the scsi card through virt manager. When we try to boot the domU it won''t boot. We need to update fstab and menu.lst, but we need to boot with the hardware attached to see how it''s being seen by the domU. On a physical machine we

I'm using yum-pull for creating a local yum repo. I have a non-root user that runs the script and the files are stored in that user's home directory. I'm trying to make that directory available with httpd. The user owns all the files and subdirs and the rights on all the files is: -rw-r--r-- I added this to the bottom of httpd.conf and restarted httpd. Alias /repomirror

Yesterday all of my xen servers went down hard and also lost connection to ocfs2. 95% of the domU''s came back up ok, but I do have problems with a few windows domUs. They seem to start ok, but them immediately lose connection to the network. If I have them on DHCP they are on long enough to get an address, then they lose connection. If I look at the properties of the NIC it says 1GB

So yesterday I got was able to get a domU successfully using a PCI SCSI card. This morning I restarted the host server. When I try to start up the same domU I get this error: Error: pci: improper device assignment specified: pci: 0000:0e:04.0 must be co-assigned to the same guest with 0000:0e:04.0, but it is not owned by pciback. How do I make this card owned by pciback on reboot. Do I need to
