I am trying to find the proper way to setup a NFS4 Server with two clients. I have:
FileServer: CentOS 5.5
-IP:10.1.1.200
-User: Max
-Export: /FS-Data
[code]....
User/Group Max owns FS-Data on the FileServer, How do I go about mounting it on the clients, since root can only mount?
i'm trying to setup a nfs4 server and client. i followed the instructions in
[URL]
The SERVER is on 192.168.89.1 running Xubuntu 10.04, and the CLIENT is on 192.168.89.128 running Ubuntu 10.10. Firewall is disabled on both the server and the client for testing purposes. /etc/default/nfs-kernel-server on the SERVER:
Code:
# Number of servers to start up
RPCNFSDCOUNT=8
# Runtime priority of server (see nice(1))
[code]....
because we want UID/GUID to be mapped from names. This way, server and client do not need the users to share same UID/GUID. In that case,
1. Should i set those 2 fields to "no" and "yes" respectively instead?
2. Or else, how do i make sure that the uid on the server is mapped to something useful on the client instead of nobody and nogroup?
I'm trying to setup a NFS4 server (no security, local home network behind FW). It seems that I'm missing something because 'rpcinfo -p' does not list v4 for NFS: petit-pois:/home/eric# rpcinfo -p

I'd like to setup a Linux VPN Server that allows Windows clients to connect. What would I have to do to accomplish this?
View 2 Replies View RelatedI have tftp-server running on Centos 5. Clients which are on the same subnet as the server are able to get and put without problems. I have a client that is across the internet that is having trouble getting files from my tftp server. A tcpdump reveals that the client is requesting the same file over and over again. In /var/log/messages, I am see the following error repeated over and over until the client finally gives up.
localhost in.tftpd[12727]: tftpd: read: No route to host
At my work, we have several clients (outside clients) that have an FTP login to our FTP Server. Their login then leads them to their home FTP folder. The FTP server is currently a Win2003 box. Because we have so many clients, we would like to implement some form of WebGui that would allow each client to manage their own FTP home folder and user info, such as resetting their password if they lost it.
Is there anything like this available in linux that would provide us with that kind of control/usability?
I have a server (called NAS) that shares out /public, and I also have this same server running KVM with some VM's. I am setting up the first VM now, and one of the things it does is download torrents onto the share. I am connecting it via "mount -t smbfs //nas/public /mnt/nas" from the VM on the host and it seems to work fine. However whenever I add a torrent to the queue on the VM to download, all downloads stop and seem to be disconnected. I can restart them after a few seconds, but they will stop after a few minutes with another disconnect error. I have the network interface bridged, so I thought it was talking directly to the host.
The appropriate lines in my smb.conf:
security = share
[public]
comment = Public Stuff
path = /public

We recently upgraded our NFS server from Centos 4.4 kernel 2.6.9-42.0.10.plus.c4 to Centos 5.4 kernel 2.6.18-164.6.1.el5
In our queue directory where we shuffle files to be processes some files will go missing.
Example structure
/Queues/Process1/subdir_xxx
/Queues/Process1/subdir_xxx
etc...
/Queues/Process2/subdir_xxx
/Queues/Process1/subdir_xxx
etc...
Where 'xxx' is a date/time string down to the second.
Each subdir entry contains a number of files, depending on load at the time.
What we see happening is that a subdir will appear empty from a client (ls -la shows . and .. ) but an rmdir will fail with a 'directory not empty' error. From all 7 clients (mix of Centos 4 and 5). However on the server the files are visible. If we 'touch' the files the clients will then pick them up and process them.
It doesn't appear that waiting any amount of time will make the files visible (we've waited 8 hours while testing).
We've tried different mount options, NFS4, etc. Nothing got rid of the issue. Changing one server to use CIFS however solved it. So it appears to be some bug in NFS.
The problem appears to be intermittent and random, we can go hours without seeing it, or minutes. I'd say it affects fare less then 1% of the files written.
I can't seem to get the X server to allow access from clients on other hosts. (I know, not exactly a network problem, but. I made the change in /usr/share/gdm/defaults.conf to be : DisallowTCP=false
and this worked on another CentOS system, but it hasn't fixed it on this one. What other things could prevent other clients from connecting to the X server? From the local host, I get :
Warning: Tried to connect to session manager, Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed although the client DOES actually create the window and work! So, maybe this message is a clue.
From the remote host, I get : Error: Can't open display: 10.10.1.20:0.0 Which is not terribly informative. Is there a log somewhere which details why a connect request was denied? The files in /var/log/gdm are not very informative.

I'm new to Centos 5 (and Linux) and, after installing Centos, I configured Samba, Apche, ... w/o problems (through interactive interface). My problem is tha t I need to use DHCP (all our clients use dynamic IP addresses for the ease) but I don't find dhcpd ... nor the sample config file(s).
Note : the new server I intend to use is actually connected on a LAN with an 'old' DHCP server (still under W2K server), is this the reason why I can't find/activate dhcp on my new machine ???
We are trying to set up a NIS server on a CentOS system. We need to have a NIS server which can provide NIS authentication to a couple of clients. We are practically new to all this stuff.
Just googled to find some ideas about installing ypserv and ypbind and portmapper. We did all that and also started them successfully. But now the clients are not able to join to the NIS domain . The error log states "YP_DOMAIN NOT BOUND".
I guess we have not entered the /etc/yp.conf, /etc/hosts files properly. Please let us know the detailed steps to setup a NIS server .
Also, please let us know what entries should go into the different /etc/<file_names>? What is meant by HOSTNAME in the /etc/hosts file?
Is there any other files which need to be changed? Are we missing any steps?
Also to add-on, while executing the ypinit command we faced the following error:
At this point, we have to construct a list of the hosts which will run NIS servers. localhost.localdomain is in the list of NIS server hosts. Please cont inue to add the names for the other hosts, one per line. When you are done with the list, type a <control D>. next host to add: localhost.localdomain next host to add:
The current list of NIS servers looks like this:

I am connecting servers using NFS4 the shared directories are on servers running Debian 4 while the one who read from them is Debian 5.0.3. The problem is one of these shared servers suddenly stop responding and you cannot list it from Debian 5 server, also df hang, and the web application that is using it does not respond to requests that use this shared directory since it is blocked. Then the load on the server start to increase until the server cannot respond (over 90). I have found many entries in the syslog that refer to this like:
ma25555 kernel: [1200285.732919] nfs: server 10.xxx.xxx.xxx not responding, still trying

I have tried the connection between the 2 servers using ping for one day and all are OK (zero lost)
There are 3 other servers that are running Debian 4 and are working fine.
I have openvpn tunnel setup between two CentOS servers. One of the CentOS servers also acts as a DHCP server for some client computers.
Server A= OpenVPN server
Server B= OpenVPN client (connects to Server A with OpenVPN)
The two CentOS servers can ping each other (172.16.0.0/24) via the tun0.
However, client computer connected to Server B (DHCP server) can't reach 172.16.0.1 (which is the OpenVPN server).
I think I am missing some routing in my "ip route show". Following is the full picture:
What command can I issue to get this fixed? something along ip route add?
There is no firewall service on both end. service iptables stop! I can't bridge eth1 and tun0 as DHCP server might mess up the other side. I can't do a push of "redirect-gateway def1" because then clients loose their IP as they send DHCP requests to Server A.
So I have a few Ubuntu (Hardy till I can find a replacement for Xen) boxes that I am trying move from nfs3 to nfs4.I set it up according to this guide: URL...However I ran into trouble when the client see's all users/groups as nobody/nogroup.The current set up is that all the boxes have synced uids/gids and all users with root access can be trusted. I read some reports that said the only way this could be fixed was by using Kerberos. However I would really prefer not having to move to Kerberos as I have heard that it is very intensive to set up. So what I am looking for here is a solution other than sticking with nfs3 or putting everything on Kerberos. However if you think that Kerberos is easier to set up than I am giving it credit for then that could be useful to hear as well.

Linuxquestions--I posted this over on the CentOS forums, which are not as booming. Then I remembered these forums for when I had my VPS way back when and you guys were pretty helpful, of course expected me to mostly do my own reading which I dont mind its just having a hard time understanding some of the things in what I was reading. I even believe I came here with this problem before but abandoned the issue because my VPS was not powerful enough or something of the sort, but this was many years ago also on CentOS using apt. Now using yum which I like much better.
I am trying to set up a mail server on centos5 using sendmail and dovecot, and eventually spamassassin and some antivirus filter as well. I'd also like to get the proper secure auth mechanism set up at some point too. But for starters, I've been having a lot of difficulty trying to even connect to the mail server from a client computer in the local network. I installed Eudora on the client and after some tweaking in dovecot I was able to connect to the mail server, but then when I try to send an email I get a "connection refused" error, with nothing being logged on the server that I can see.
The last time I set up a mail server was Fedora Core 2, so the configuration files have changed a bit to say the least, and I can't really refer back to those to set up this new server. Does anybody know of a good step-by-step doc on getting the mail server going? I've read the man pages and other various readme's, but these really only list out the available options with no really good explanation of what needs to be done to get the mail server going. If there isn't a full write-up on how to do this, I'll put something together when I'm finished so others can use it in the future.
I have just installed CentOS 5. I have set mysql database to access from remote machines. But now the problem is it is not connecting from the local machine now.
View 5 Replies View RelatedWe have two CentOS 5 servers in production (web and database). We are setting up a single staging server that will mirror the configurations of these servers as closely as possible. What is the easiest way to ensure the exact same software and configs as the production servers are setup on the new staging server. Our contracted data center provider has already informed us that they do not perform images and NO we do not have physical access to the machines. It is undetermined whether we will be virtualizing the staging server into two virtual servers yet, so for the purposes of this post lets assume we are not. I'm seeking a faster/more precise method than doing this by eye and hand.
