Re: [CentOS] Netinstall & NFS using local server.

ok, playing around with netstat I figure all the ports that need to be open in iptables for this thing to work, I figure having the firewall down was too big of a risk so why not figuring out the ports and opening them in iptables and sharing the knowledge with you guys. The following ports are to be open: 111 tcp/udp 32803 tcp/udp 32769 udp 892 tcp/udp 875 tcp/udp 2049 tcp/udp If I only mentioned tcp or udp after the port it means either or both, if you see one/two it means both protocols must be enable. Also make sure you tweaked around you /etc/sysconfig/nfs file, I noticed that by default you need to have some of the stuff from there un-comment for it to work, I will post my file so you can use it as a skeleton to change yours. If you have any questions let me know and I will try to help you out. My nfs config bellow ( this only applies to Centos 5.5), I didn't test in another release.

using kvm
by Jerry Geis 05 Jan '11

All - I am running a virtual windows 7 (pro 64) on centos 5.5 x86_64. I was hoping to run virtual XP inside windows7 in this configuration. I get an error about cannot start virtual XP when I try this. Do I not have something setup correctly or can I not run a "double" virtual environment? Thanks, Jerry

Converting to maildir
by Jason Pyeron 05 Jan '11

05 Jan '11

Looking for a guide on converting to Maildir. Here are our relevant specs. sendmail-8.12.11-4.RHEL3.6 (we may not be able to upgrade this due to too many modifications) imap-2002d-14 procmail-3.22-10.el3.centos.0 To a maildir setup... <rant> I was in a panic today at work because the backup server is filling up too quickly, backing up peoples email. Further it is not backing up often enough. I just lost all of today's email. I hate mbox and imap and outlook... </rant> All the maildir stuff I can find is postfix oriented. From what I can read in procmail man pages, it supports maildir and sendmail uses procmail as the LDA, hence sendmail "supports" it. -Jason -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- - - - Jason Pyeron PD Inc. http://www.pdinc.us - - Principal Consultant 10 West 24th Street #100 - - +1 (443) 269-1555 x333 Baltimore, Maryland 21218 - - - -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- This message is copyright PD Inc, subject to license 20080407P00.

Thank you for the responses, still I don't find an answer. I am learning Centos from the ground up, I need to learn how to install this via NFS. I am aware that FTp and HTTP and options available, but what is the point of having NFS during the install if it doesn't work. I need to find a way to get the installation going at least for learning purposes. If you have any clues give me a hand, I am not planning to have to running in my environment but at least i would have the concept under my belt.

noob question about mock
by nux＠li.nux.ro 05 Jan '11

05 Jan '11

Hi, Been recently more and more tempted to use mock for building rpms, but looking at it I have one problem. As far as I could read about it, mock essentially rebuilds srpms so to use it I would need a separate "classical" build environment to create those srpms in the first place. Am I right or did I get something terribly wrong? Cheers! -- Nux! www.nux.ro

Anyone using PHP52 packages from iuscommunity.org?
by robert mena 05 Jan '11

05 Jan '11

Hi, I need to use PHP 5.2 in my Centos 5.X servers. I've been using the one found in Testing for more than a year without problems but I feel that it is not being updated in a while, specially with the security issues. I found a post about this iuscommunity.org which maintains 5.2 and 5.3 rpm packages for Centos/RedHat but I'd like to know if anyone in this is using the 5.2 packages in a production environment.

Netinstall & NFS using local server.
by Lisandro Grullon 05 Jan '11

05 Jan '11

Dear CentOS community, I have install centos via CD, DVD and Directly off the net via http and FTP. Now I want to do a NFS install from a local server and a client. Both, client and server are in the same vlan 10.14.10.0/255.255.255.0. The server has a static 10.14.10.15 address and the client gets its own address via DHCP. I download the DVD image from one of the mirrors and placed it under /centos-media/centosdvd32/DVD/CentOS-5.5-i386-bin-DVD.iso which is a dedicated partition on the server to hold all images. After that I exported the usual entries under /etc/exports and reloaded NFS using /sbin/service nfs reload. This is what my exports file looks like: [root@zeus DVD]# cat /etc/exports /centos-media/centosdvd64 10.14.10.0/255.255.255.0(ro,sync,all_squash) /centos-media/centosdvd32/DVD 10.14.10.0/255.255.255.0(ro,sync,all_squash) After doing so, I also modified the entries under IPtables to allow traffic in 111 and 2049 at the UDP/TCP level and restarted the service as shown bellow. [root@zeus DVD]# cat /etc/sysconfig/iptables # Firewall configuration written by system-config-securitylevel # Manual customization of this file is not recommended. *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :RH-Firewall-1-INPUT - [0:0] -A INPUT -j RH-Firewall-1-INPUT -A FORWARD -j RH-Firewall-1-INPUT -A RH-Firewall-1-INPUT -i lo -j ACCEPT -A RH-Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT -A RH-Firewall-1-INPUT -p 50 -j ACCEPT -A RH-Firewall-1-INPUT -p 51 -j ACCEPT -A RH-Firewall-1-INPUT -p udp --dport 5353 -d 224.0.0.251 -j ACCEPT -A RH-Firewall-1-INPUT -p udp -m udp --dport 631 -j ACCEPT -A RH-Firewall-1-INPUT -p tcp -m tcp --dport 631 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited -A RH-Firewall-1-INPUT -s 10.14.10.0/24 -m state --state NEW -p tcp --dport 2049 -j ACCEPT -A RH-Firewall-1-INPUT -s 10.14.10.0/24 -m state --state NEW -p tcp --dport 111 -j ACCEPT -A RH-Firewall-1-INPUT -s 10.14.10.0/24 -m state --state NEW -p udp --dport 2049 -j ACCEPT -A RH-Firewall-1-INPUT -s 10.14.10.0/24 -m state --state NEW -p udp --dport 111 -j ACCEPT COMMIT [root@zeus DVD]# /sbin/service iptables restart When I try loading the net-install disc from the client i get to the area where I specify the Ip of the server and the NFS path in the server, hitting enter returns "That directory does not seem to contain CentOS installation tree", I triple check the ISO and I know its there with all appropriate permissions. Can someone tell me what am I missing? I have spend all day trying to get NFS working in the local vlan, i know that all ports are open within the vlan at the routers level. Any clues?
