CentOS 5 Server :: NFS - Mount Clntudp_create: RPC: Port Mapper Failure - RPC: Unable To Receive
Aug 27, 2010
I installed NFS and portmap for export a folder to another PC. /usr/local. ftp is server's hostname and ws01 is client's hostname. I edited file /etc/exports with next text: /usr/local ws01(rw,root_squash) *(ro)
I restarted service portmap and nfs. From client, I try check connection with server with command: showmount -e ftp and result is: mount clntudp_create: RPC: Port mapper failure - RPC: Unable to receive

I'm using Ubuntu 10.10 x86_64, with 2T HDD x5 grouped as RAID5 using RAID controller (dell perc 6/i), result in a 8TB disk, and I put it to a single partition in XFS. Just now one light bulb went wrong and caused whole house power fail, sadly during that time I'm copying some data to that partition. After I clear the power issue and turn on the computer, the partition still can mount, so I continue copying, and that gives me some IO error. I assume it is some kind of problem that need a file system check, so I unmount it, and run xfs_repair.
However xfs_repair shows the partition has not been unmount so I restarted the computer. After restarting, during the loading screen the system prompt me that it cannot find the file system, and I pressed 'S' to skip (btw 'M' for manually maintenance, but I didn't try) Then there comes the problem: the partition cannot be mounted anymore. I tried using palimpsest (the disk utility) to check, the partition shows normally (i.e., there's a 8T disk with a single partition in XFS), but when I try to mount it, the first time I click 'mount' results in nothing, repeat click will get an error 'The device is busy: A job is pending on /dev/sdb1'.
Checking the process running I found this:
process 'mount', status 'uninterruptible', command line 'mount /dev/sdb1', waiting channel 'call_rwsem_down_write_failed'.
Also other operations with that partition does not work, such as xfs_repair or mount, will just halt (and the waiting channel is 'get_sb_bdev')

I have two situations here :
1) I have my Nagios running on the linux box and BMC Remedy Server on the Solaris box. I have simulated a mail from Nagios to be delivered to the Remedy server. But the Remedy Server does not receive it. I even tried snooping on port 25 but nothing has reached the box.
2) I have my Nagios running on the linux box and BMC Remedy Server on the Solaris box. I have simulated a mail from Nagios to be delivered to the Remedy server. I snooped on port 25 on the Solaris box. I could see the mail reaching the box, but it is not being forwarded to the Remedy inbox.

Well as you can see from my sig I am running Slack 13 and unfortunately did not discover the readme_crypt.txt on the installation cd until it was far too late. Not to worry, many hours burned and things learned.So I compiled and installed cryptsetup and for my test encryption I am using an external usb harddrive (sdb3).First off cryptsetup kept segfaulting with the luksFormat command and this seems to be a know bug. The workaround it to pass USE="dynamic" to config before you build the package. Then
Code:
# cryptsetup.dynamic -h sha512 --verify-passphrase luksFormat /dev/sdb3 test-crypt
# cryptsetup luksOpen /dev/sdb3

I am using Ubuntu 10.04 on a dual-boot system with Windows 7. Yesterday I upgraded from 2.6.32-23 to 2.6.32-24. After that, pressing the shutdown button and selecting shutdown or restart (whether on the login page or after I've logged in) will only bring me back to the login page. I can shutdown or restart if I do sudo shutdown now, but I'd prefer to use the GUI. Also, there is no sound now (not a big deal, but still not good). And I can't access my storage partition (not the windows7 partition, but a third ntfs partition with data on it). I get the error message that I am unauthorized to mount. I have the only account on this computer, so I should be authorized. This one is a HUGE problem for me, because I need to be able to access my data for work. None of these were problems before the upgrade.
Oh yeah, and quickstart is not enabled. Also, if I go to Power Management, and try to alter what to do when Power Button is pressed, my only option is Ask Me. I know these have been problems/solutions to the shutdown/restart problem in the past.

It's been awhile since I posted anything which is a good sign my install has been working well and I have been able to handle most everything. However, I'm not able to handle this issue. I recently installed F11 and everything went well. But, when trying to see my other computers on the local network, I cannot. I receive this error message: Unable to mount location Failed to receive shared list from server. I understand the message as it is obvious, but do not know how to fix it.

I'm wondering why we can't received email when our primary DNS went down. We have slave DNS but don't know why we can't receive emails. Internet is working properly. The mail file in /etc/configuration on slave dns are there & the zone file is added. I edited the mail zone file to see if it works & restarted the named service. But still we can't received emails using the slave DNS. Do I need to reboot the server?

I recently purchased a domain and I have setup what I believe are correct dns records from the domain companies control panel. I have the domain pointing to my server and that's working fine. I also have an MX record for my domain. Now, I can send emails from my email account just fine however I cannot receive any emails coming in to my account. Heres an example:
[dalton@int-interactive mail]$ echo "hello world" | sendmail -v dalton@int-interactive.com
dalton@int-interactive.com... Connecting to [127.0.0.1] via relay...

I have a server with Fedora 13 with which I would like to get NFS working. I have looked up multiple howto's and tutorials, but I'm having a problem not addressed by any of them.Official how-to, another how-to, and another how-to.I have verified that nfs-utils, nfs-utils-lib, portmap, and system-config-nfs are installed and running. I have verified that I have, in fact, shared the directory that I want to share, and that the proper permissions are set.
I had to go through some gyrations to get the Belkin wireless N router to allow my server to have a static IP. However, I can ping the server from the nfs client (a toshiba satellite running mint 8), and vice versa. I have (for now) disabled firewalls on both computers. I think I have disabled SELinux on Fedora 13 (for now).When I attempt to connect to the server from the client, the output looks like this:Quote:
aragorn ~ # mount -v 192.168.2.101:/test /home/kelev/test/
mount: no type was given - I'll assume nfs because of the colon
mount.nfs: timeout set for Sat Dec 18 12:21:09 2010

I am using CentOS 5.2. I am installing from disc on a machine with Intel Embedded Server Raid Technology. It has two 500 GB SATA drives. During the initial boot process, it sees that these two devices exist. However, after getting into the screen to partition and configure RAID, it just shows this:
Drive /dev/mapper/ddf1_MegaSR R! #0 (475879 MB) (Model: Linux device-mapper)
I want to do a RAID1 so that the disks are mirrored. However, I would expect to see both drives listed. I can select RAID to create RAID partitions, but I think I need to be able to see both drives in order to do this correctly.

I am trying to setup a H/W RAID-1 matrix but I am unsuccessful. I am trying to get partitions installed as /dev/md0, /dev/md1 but it keeps going for /dev/mapper/isw...The reason is that I have R1Soft backup and it needs to hook the partitions as seen in /proc/partitions from /dev not /dev/mapper/isw. I have tried to boot the installation with various options but nothing!

My config :
Dell PowerEdge 2900III
16Gb RAM
2 arrays RAID1 (2*(2*500Gb))
CentOS5.5
VMWare 2.0.2 (with workaround of downgrade glibc to CentOS5.3)
Since the upgrade from CentOS5.4 to CentOS5.5, it seems the sshd is crashing every other day.I can access to the VMWare webserver, but no way to connect through ssh port 22.The only "workaround" is a hard reboot of the server, and with luck, I can access to the server through ssh.I checked /var/log/secure, it looks like time to time when the server start, it does not start the sshd service, there is no entry at all for the time the server started up. For instance today, the server has been started early this morning, but the first entry was found after a hard reboot this evening : Jun 3 18:19:14 hercules sshd[3617]: Server listening on 0.0.0.0 port 22.

I am trying to prevent the dm_mod and friends from loading during install.I am installing by PXE boot with NFS and kickstart files over http. This works fine for other machines.Ok, I have a Dell PowerEdge 2900 III with 8gig ram, PERC 6/i raid controller.The raid has 8 1TB drives in it, so the total size of the device is >2TB.There is also an SATA drive, which is NOT on the raid controller.
The problem is, I want to install CentOS on the SATA drive. The SATA drive comes up as a device-mapper drive, with a big crazy device name.This is ok, but the problem is, when the system goes to boot, it just says 'missing operating system'.I can't boot from the raid because it is large enough to require a GPT partition, and CentOS says it can't boot from a GPT partition.The SATA drive would work FINE if I could just prevent the damn device mapper from loading, so that I could install on the SATA drive in ordinary SATA mode.
I have tried re-squashing the stage2.img with /etc/modprobe.conf with alias dm_mod off and such, no luck.I also tried adding an /etc/modprobe.d/blacklist file, that did not work either.I also tried putting blacklist= dm_mod in the kickstart file, but that seems to be a fedora-only option and it kills my install. any ideas on preventing the dm_mod et. al. from loading at install time??

I have nfs-server installed and running on my Ubuntu 10.04 server. I have some directories exported. I can connect from my Ubuntu 10.04 PC using the commands:
sudo mount taylor10:/data0 /t10/data0
sudo mount taylor10:/data1 /t10/data1
sudo mount taylor10:/data2 /t10/data2
sudo mount taylor10:/data3 /t10/data3
However, when I have my firewall on the PC enabled (Firstarter) I cannot make the mounts. I have ports 111 and 2049 open. If I stop the firewall, do the mounts and then start the firewall I am still mounted to the nfs shares. The connection is on port 2049. I have observed that when the firewall is enabled and I issue the mount command I get traffic on a random port such as 46694, 37022, etc. I have found instructions regarding editing /etc/default/nfs-common but they seem to control the port the server is listening on, not the port which the client is asking on. How do I lock down the port which mount and/or the nfs client is using to talk to the server to make the initial contact.

Trying to do a yum update to get everything to latest, towards the end it says this:
[Code]...
how to get around this? I tried yum clean all, then yum update, again but it did the same. I had other deps missing on other servers but yum clean all fixed them -- can't find anyone else who's had this specific issue either, nor an rpm called 'device-mapper-event' or the other things that are missing - am kinda stuck!

I had a power failure the other day and my server shutdown abruptly. After bringing the server up I noticed that the /var partition came up as read only. I was not able to edit the crontab, not able to write to files within /var/log/ and do other write operations within /var.
I did a mount and it showed that /var was mounted read and write but when trying to run certain operations the system was still saying that it was read only.

Before to describe my problem I want to say that I searched a lot on the internet and I think I tried all the solutions provided by other users to similar problems.
I've got an IBM xSeries 346 server running CentOS 5.5 with all updates applied with yum.
The video card is an ATI Radeon (lspci says: 01:06.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE]).
Everything worked fine until a bad day where there was an environmental power failure and the server crashed.
I turned it on, I manually check the file system, some files went lost and after the reboot the X server didn't start.
After the first boot I had problem with /etc/rc.d/rc.sysinit, sbin/multipath.static and /dev/cpu/microcode, I solved them and now the message it shows is:
"Failed to start the X server (your graphical interface) It is likely that it is not set up correctly. Would you like to view the X server output to diagnose the problem?"
I choose OK and it appears an empty log, if I go in /var/log/gdm and I do an ls -al:
total 0
-rw-r--r-- 1 root root 0 Oct 28 04:44 :0.log.4
-rw-r--r-- 1 root root 0 Oct 28 04:44 :0.log.3
-rw-r--r-- 1 root root 0 Oct 29 04:52 :0.log.2
-rw-r--r-- 1 root root 0 Oct 29 04:52 :0.log.1
-rw-r--r-- 1 root root 0 Oct 29 04:52 :0.log
So a lot of empty log files.
I press enter on the OK that appears at the bottom of the screen and it says: Would you like to try to configure the X server?
I choose Yes, I enter the root password and appears the following messages:
Couldn't start X server on card 0
Couldn't start X server with old config, trying with a fresh configuration
Then another messages:
Trying to restart the X server, I press enter on OK and it loops the initial message ("Failed to start the X server...)
