Networking :: Access Denied By Server While Mounting Storage
May 8, 2010
I set up a nfs server that is working locally only, on remote I get this:
root@poc ~]# mount -t nfs storage:/var/ftp/pub /net
mount.nfs: access denied by server while mounting storage:/var/ftp/pub
This is my exports file:
/var/ftp/pub/downloads 192.168.1.23(rw,sync)
/var/ftp/pub 192.168.1.23(ro,sync)
this is my rpcinfo -p
program vers proto port service
100000 4 tcp 111 portmapper
100000 3 tcp 111 portmapper
100000 2 tcp 111 portmapper

Firewall has 2049 open only. Other services suck as nfs or status, lockd have random ports, so firewalled.
I recently installed CentOS 5 as my server. I have samba running 100%, today i was working on NFS i had it semi working at one point where i could mount to the shared folder but i could not see any of the files in it, now when ever i try to access it i get, mount.nfs: access denied by server while mounting 192.168.1.100:/Server
i'm trying to setup a nfs4 server and client. i followed the instructions in [URL](nfsv4 quick start section) and [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]....
On the [URL], i see some steps related to portmap on the "NFS Server" and "NFS Client" sections. Would i need those steps as well? There's also a list of steps on [URL] (linked from [URL]. Are those necessary?
EDIT: Running showmount on the client seemed to show that NOTHING is shared on the server:

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?
Since FC6, NFS became very finicky and seemingly causes servers to randomly denying mounts from some terminals but not others, with all exactly the same new FC installation and exactly the same hardware - crazy!. The only difference is hostnames of the terminals trying to mount NFS volumes on the server and I made sure that /etc/hosts on all terminals and servers contain each others ip addresses and hostnames. I always uninstall SELinux which is truly a huge pain in a corporate environment. Is there ANY way I can relax the NFS authentication on the server in order to make sure clients can mount volumes?
e.g. the following is encountered often, with sometimes crazy situations that clients can only mount nfs volum es from the server after I first boot the server and then ALL the terminals. It is painful as you might agree! Other way round, no go, client will not mount until server is booted and then client booted.
In this case I really prefer windows lackey security. It works. Never mind how crappy windows is, at least I don't have diabolical access problems on servers.. NFS used to be very nice about 6 years ago but truly sucks recently imo. /]# mount -o soft -t nfs nfsserver:/public /xfer mount.nfs: access denied by server while mounting nfsserver:/public
I just built an AMD Phenom II Six Core with 4 Gigs Ram a 160Gib / and swap, and (2) Two Tb mirror for Raid (data storage) I had been using DMRAID in the deprecated box but this box has MDADM v3.1.4 - 31st August 2010 from source (on MDADM wikipedia).
I have no permission problems with using the raid and dmraid is un-installed. The raid is working perfectly and is mounted in my fstab with ext4 defaults 0 2 as my options.
I have two exports /media/raid/Test /test
Both show IP and subnet on the showmount -e for the server. I can mount the test just fine on the server. I cannot, however, mount the /media/raid/Test error: mount.nfs: access denied by server while mounting hostname:/media/raid/Test Using dmraid I am able to have the deprecated box export and mount nfs shares from the raid but using MDADM on the new computer, I cannot. I get similar results with pointing MYSQL's data folder to a location on the "/media/raid/Database" (even with apparmor entries).
I run a mediaserver on Archlinux, working perfectly (or almost). I have set up NFS v3 and that worked for me on these clients:
- Debian Lenny - Archlinux 64bit
Now I've upgraded my Lenny-box to squeeze and I see that 2 of my 3 shared folders (tdone and twatch) are mounted like they should and the third one (media) doesn't come up. A 'mount -a' as root gives this error: mount.nfs4: access denied by server while mounting (null) My relevant fstab-lines:
Setup1: Two rack mounted servers with a common storage device serving as the home directories for users on the servers. The storage device is a gfs partition mounted on the servers as the home directory using SAS cables. These servers have RHEL 5.4 as the installed operating system.
Setup2: A standard tower server with Debian 6 as the operating system used for tape backups. This has a tape drive connected to it.
Question: How to mount the storage device of setup1 using NFS on the server in setup2.
I configure named and stumble upon the following problem: named is serious about user rights, every config file named uses should be named:named. I set rights to named:named as follows, but they get changed to root:named when I restart named as root. The same thing happens with SELinux context. This results in access denied type errors.
I have a shared directory on another machine but I can't get it to mount as a samba share. The permission denied doesn't say where/which permission is denied. Is it on the remote on on the local machine? The remote has sharing enabled for the shareddocs directory and after I have mkdir'ed the local mount point I open it's permissions too. The verbose response from mount.cfis looks like this:
mount.cifs kernel mount options: unc=//192.168.1.102shareddocs,domain=WORKGROUP,ver=1,rw ,username=clive,,,,,,,,,,,ip=192.168.1.102,pass=** ****** mount error(13): Permission denied Refer to the mount.cifs( manual page (e.g. man mount.cifs)
I have a linux domain (FEDORA CORE 1) and two laptop's which are part of my domain with windows xp pro service pack 2.I have given two ip's to both the laptop's being primary as global and secondary as local.I have configured printer in one laptop and shared.Till last week i was accessing that shared printer from my other laptop and every thing was working fine.Last week i formatted one laptop,(which dose not have shared printer) from then onwards i am not able to access my other laptop. I get the following message when i try to accessmy other Laptop,"you might not have permission to use this network resource. contact the administrator of this server to find out if you have access permission there are currently no logon servers available to service the logon request"P.S : If i have only local IP i am able to see both the systems and i am able to access my printer, this problem comes only when i add global IP to both the machines.And also i have stopped the firewall and other things.
I am attempting to Kerborize an NFS server on a RHEL6 machine, but I cannot get it quite right. The error message I receive when executing the following command (as myself, not as root) is:
Code:
I have a keytab generated from the KDC for both NFS server and NFS client (both RHEL6 hosts) placed in /etc, and I have configured PAM/Kerberos so I can login via SSH and see I have a valid ticket with klist.
I can login to both NFS server and NFS client via SSH and get a ticket, but I don't know where the problematic NFS permissions reside.
The /etc/exports file on the NFS server looks like:
Code:
I have disabled IP Tables on both client and server, and hosts.allow and hosts.deny are not blocking traffic at the moment. On the NFS server.
Here is the output of rpcinfo:
On the NFS client, here is the output of that same command:
Using NFS on the client machine. I am running scientific linux on my machine. Its working fine for my other machines.I have made sure that the firewall is disabled and also the selinux too. here is what i get when i use rpcinfo -p on the client.

I have not done the SMTP debug yet but just from basic troubleshooting, I think I know what the problem is. My mail server is rejecting my web server from sending mail due to 'relay access denied':
Code: root@www:# telnet mail.domain.tld 25 Trying 211.113.101.135... Connected to mail.domain.tld. Escape character is '^]'.
I've only recently encountered this problem with vsftpd when I was creating new ftp accounts. I keep on getting:
550 Access Denied.
on every action I try to do on ftp, no matter what. I've been trying to solve this myself however my attempts have been futile.
The permissions, and ownership have been checked and rechecked tens of times now, so thats not the issue. I've reinstalled the OS of my server twice now, and the problem is still persisting. Heres my config file, this isnt for anon by the way.
Code: # Example config file /etc/vsftpd/vsftpd.conf # # The default compiled in settings are fairly paranoid. This sample file # loosens things up a bit, to make the ftp daemon more usable. # Please see vsftpd.conf.5 for all compiled in defaults. #
Has anyone seen this? I have attached a screenshot of it to this post.
When I log in using PUTTY, as soon as I enter my username and hit enter I get Access denied, then a prompt for a password and all works well, it just tells me access denied even though it didnt deny me. its weird.
I am getting an access denied when trying to log in via SSH to my home server with putty(windows) over the internet. I can use any user including root and get the same result. If I use my Android phone with the ssh terminal command I am able to successfully log in and use the server.
when client goes to bind to NFS share on remote server - they are getting access denied when using the mount command; [SERVER] - CentOS 5.3 /etc/exports /mnt/data 192.168.5.199(rw) - implying the client I want to have access
I have configured mail server with postfix with dovecot with no encryption: When connecting with Thunderbird imap is working fine. When sending email from another domain to this domain again it is fine. But when I want to send mail from my domain to another it gives me error and this is /var/log/maillog: Quote:Jan 18 18:23:09 srv1 postfix/smtpd[3991]: NOQUEUE: reject: RCPT from unknown[95.81.67.120]: 554 5.7.1 <Recipient email>: Relay access denied; from=<Sender> to=<Recipient email> proto=ESMTP helo=<[127.0.0.1]>
I'm having a hard time to access MySQL from the local or remote shell. If I try to access MySQL, using mysql -u root -pxxxx I get the error 1045 Access denied...
MySQL is running and I can access it, using phpmyadmin.
There must be something blocking shell access. Can anybody confirm and tell me how to check/configure for shell access? I'm using ca preconfigured CenOS from PBX in a flash and it seems they did some security settings - but I can't find any further information. I know I should probably post there, but the Mods didn't activate my account yet. And you know how it is if you try to figure something out. You won't stop.
11.3 in use with KDE. When I plug in an USB stick or my HTC phone into the USB connector the device is recognised but can't be opened in dolphin. This is the error message:

I installed SQUID3 on a Linux machine with two ethernet interfaces (eth0 and eth1). I used the default settings in the squid.conf file and uncommented the two lines
Code:
And
Code:
eth0 is connected to a router, which provides Internet access. It is assigned an IP 192.168.1.2 by the router. I manually configured eth1 to have an IP address 192.168.5.1. It is connected to a switch. Systems having IP addresses 192.168.5.x are connected to this switch. I ran these two commands for NAT:
Code:
Code:
But when I try to access internet from a system having IP 192.168.5.2 through the proxy I get an error that says "Access denied". What is wrong with my configuration?
I had 10.04 set up in my computer so that I had two folders in home, they connected to folders in a windows 7 computer by adding the following to the fstab file:
I have a dual boot Dell Studio laptop with Windows (VISTA) and Ubuntu (9.0.4) installed on it. I have recently installed Ubuntu to make it a dual boot. Before that I was using LiveUSB Ubuntu image for six months (without any problems).
During the installation of Ubuntu, I created a Linux partition of 2GB for Ubuntu installation (assuming that it was running successfully on my 2GB USB drive). All of my other work (e.g. documents/programming projects etc.) are stored on the Windows partition (which is loaded during the boot time automatically). The problem is that I get a "permission denied" error while running any executable file on the Windows partition. But if I copy the same executable on the Linux partition, everything works perfect. Am I missing something here?
I have verified that the executable have necessary execute permissions.
