NFS problem
I'm trying to NFS-mount a CentOS directory on my Fedora laptop, but I find I can only do this is I turn off the firewall on the CentOS server. If instead I go to system-config-securitylevel-tui on the server, and allow NFS4, this does not do the trick. Nor does allowing port 2049. What do I need to allow? [I should say that the CentOS server is remote, and difficult to access directly; that

firewall setup for nfs
Below is my firewall rules for iptables. everything is working fine except for NFS I cannot mount my drive. If I turn off iptables I can mount. Looking at this : http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-nfs.html Important In order for NFS to work with a default installation of Red Hat Enterprise Linux with a firewall enabled, IPTables with the default TCP port 2049

NFS client firewall config?
Hi all, Which ports do I need to have open on an NFS client's firewall to allow it to connect to a remote NFS servers? When I disable iptables (using ConfigServerFirewall), it connects fine, but as soon as I enable it, NFS gives me this error: root at saturn:[~]$ mount master1.mydomain.co.za:/saturn /bck mount: mount to NFS server 'master1.mydomain.co.za' failed: RPC Error: Unable to

Netinstall & NFS using local server.
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

NFS and Firewall
Hi Folks, I'm using VMWare on a Linux Host (CentOS) with a Linux-Guest Sidux). And I'd like to use NFS. Furthermore I'd like to use the Firewall in CentOS with this little GUI. If I activate this firewall then my Guest says "no route to host" on mounting nfs. Firewall disabled -> no problem occurs. Is there a solution to use firewall _and_ nfs ? Please, no iptables

Open extra ports on firewall?
Hi, I'm using the preconfigured firewall that comes with CentOS 5. I configure it with system-config-securitylevel-tui, close all ports except SSH, and then open only the ones I need. Right now, on one of my desktops, I've installed AMSN, which requires opening a series of ports. I've configured the app to use ports 7000 to 7010 (TCP and UDP). When running

firewall question
My firewall config is below... I am trying to figure out why another machine has access to port 5038 on my machine based on these firewall rules. I thought the reject at the bottom would take care of all other ports? It does not. I have restarted with "server iptables restart" and same thing. I can connect from another machine to my machine on port 5038. How do I prevent this?

Why portmap is needed for NFSv4 in CentOS6
Hi all, I have setup a CentOS6.3 x86_64 host to act as a nfs server. According to RHEL6 docs, portmap is not needed when you use NFSv4, but in my host I need to start rpcbind service to make NFSv4 works. My /etc/sysconfig/nfs # # Define which protocol versions mountd # will advertise. The values are "no" or "yes" # with yes being the default MOUNTD_NFS_V2="no"

blocking outgoing ports with iptables
Hi, I'm using the generic system-config-securitylevel-tui program on a remote server to configure my firewall. So far it's been fairly decent, allowing me to open up ports and whatnot. But I want to start blocking a couple of outgoing ports on my machine. I want to lock it down so the only traffic going in our out of my machine is stuff that I specify. Is there a way to do this

Understanding iptables
In following up on the rsh "problem" I was having earlier, I decided to try out the suggestion Felipe sent about using system-config-securitylevel-tui to open up ports 513 and 514, but that doesn't seem to do the job, either. # iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination RH-Firewall-1-INPUT all -- anywhere anywhere

firewall and opening ports
Hi list. This is my first post here. Super newbie. I will try not to ask too many questions, but searching is hard when you don't even know where to begin. Hopefully someone can point me in the right direction. I have just installed CentOS 4.2. I selected to have a firewall in the graphic installer, and I opened ports 22 and 80. Fine so far. SSH and HTTP both work. But now that

Default Firewall Entries

Trimming the fat out of a Centos 4.4 Installation
Hi, just to avoid re-inventing the wheel, is there any document that can help me reduce even further a "minimum" installation of Centos 4.4 (BTW can you say 600mb is minimum)? I am in the process of creating a small Centos-4.4-based Asterisk box and I need to boot it from a CF card. Deleting useless packages will help me do what i want. Example: even a minimum install of Centos 4.4 (or

NFSv4 on CentOS 5.5
Hi, What is the magic juju that I have to put in /etc/sysconfig/autofs to get autofs to default to using NFSv4, rather than NFSv3, for mounting file systems? I don't want to place these flags into the automount maps themselves because we have a varied network with Sun, CentOS, RedHat and Macintosh systems, and the flags that have to get added to automount maps (which we distribute centrally
