Linux ntpd sendto() Bad file descriptor error and solution

by Vivek Gite on April 16, 2007 · 3 comments

Q. I’m using Red hat Enterprise Linux server. I’m getting following error in /var/log/message file:
Apr 16 16:38:02 server ntpd[22694]: sendto(10.0.77.54): Bad file descriptor
Apr 16 16:38:08 server ntpd[22694]: sendto(66.111.46.200): Bad file descriptor
Apr 16 16:38:25 server ntpd[22694]: sendto(83.133.111.7): Bad file descriptor
Apr 16 16:38:28 server ntpd[22694]: sendto(81.169.156.100): Bad file descriptor

How do I fix above errors?
A. If you are seeing Bad file descriptor errors in /var/log/messages, make sure that only one instance of ntpd is running.

Step #1: Stop ntpd

Type the following command to stop ntpd:
# /etc/init.d/ntpd stop

Step #2: kill ntpd

Type the following command to kill all instance of ntpd:
# killall ntpd

Step #3: Start ntpd

# /etc/init.d/ntpd start

Step #4: Watch log file /var/log/messages

Use tail command:
# tail -f /var/log/messages
Output:

Linux Clock Configuration

Linux Clock Configuration

Summary

This guide will help you setup the correct date and time on your Red Hat 7.x Linux system including setting up ntpd for online time synchronization.

Instructions

There are two clocks to configure in Linux, the hardware clock and the system clock. The hardware clock determines the system clock on system boot. While the system is running, changes to one of these doesn't affect the other.
Note: it's best to set the hardware clock and have the system clock be set upon a reboot. Changing the system clock by using the date program on a running system could cause date discontinuities and consequently problems. If you will be using ntpd, you probably don't need to set either of these clocks (unless the current time is more than 1000s off the real time). Just setup ntpd and let ntpd adjust the time (it will do it in small steps to keep system timestamps reliable).

1. If convenient, use Red Hat's dateconfig tool. Using the dateconfig tool will update both the system clock and the hardware clock. The dateconfig tool also allows you to setup ntpd, which will keep the system clock in sync with a remote server.
   
   If using the dateconfig tool is not an option, follow the remaining steps to configure manually. For example, if you are using a non graphical terminal (dateconfig requires X windows), you must configure manually.
   
   
2. You can use timeconfig to configure the timezone and UTC settings. Timeconfig will update /etc/sysconfig/clock and /etc/localtime.
   
   
3. Set the time zone manually if not already set.
   
   Linux uses the file /etc/localtime to determine the time zone. This file should be either a copy of the appropriate timezone file from the directory /usr/share/zoneinfo or a symbolic link. If your time zone is incorrect, create a symbolic link to the appropriate timezone file.

   # ln -s /usr/share/zoneinfo/America/Los_Angeles /etc/localtime

4. Set whether hwclock uses local time or UTC
   
   Edit the file /etc/sysconfig/clock and change "UTC=" to true or false. If you have a dual-boot system with Windows, using UTC may cause problems for Windows.
   
   
5. Set the system clock
   

   # date MMDDhhmmCCYY.ss

   where MM is month, DD is day, hh is hour, mm is minutes, CCYY is year and ss is seconds. Time should be in 24-hour notation.
   
   To only set the time:
   

   # date -s hh:mm:ss

6. Set the hardware clock
   
   To set the hardware clock to the current system clock:
   

   # setclock

   this method looks at /etc/sysconfig/clock to determine whether the hardware clock is set to UTC
   
   Another method:
   

   # hwclock --systohc
   # hwclock --systohc --utc

   use the second option if you use UTC.
   
   Set hwclock manually:
   

   # hwclock --set --date="9/22/96 16:45:05"

   Everytime you use the hwclock --set command, it will create or edit the file /etc/adjtime to determine the systematic drift. Once you have some history, you can use the --adjust option to adjust the hardware clock appropriately. Run as a cron job if you want the clock to adjust automatically on a regular schedule. Don't use the --adjust function when using ntpd since ntpd will turn the "11 minute mode" on, which is best left alone. See the hwclock manpage for more info.
   
   
7. Setup ntpd for automatic synchronization with a remote server.
   
   Run Red Hat's setup utility to make ntpd start on boot up and edit /etc/ntp.conf
   
   Set server and fudge options:
   

   server time.nist.gov
   fudge  time.nist.gov stratum 10

   Enable multicastclient:
   

   multicastclient     # listen on default 224.0.1.1

   Edit /etc/sysconfig/ntpd if necessary. The default should be fine.
   
   Start the ntpd daemon:
   

   # service ntpd start

NTP server Overview

Overview

NTP (Network Time Protocol) provides accurate and syncronised time across the Internet. This introductory article will try to show you how to use NTP to control and synchronize your system clock.



Sample ntp.conf configuration file

     server 134.214.100.6

     server swisstime.ee.ethz.ch



     peer 192.168.100.125

     peer 192.168.100.126

     peer 192.168.100.127



     driftfile /etc/ntp/drift

     #multicastclient  # listen on default 224.0.1.1

     #broadcastdelay  0.008



     authenticate no



     #keys           /etc/ntp/keys

     #trustedkey     65535

     #requestkey     65535

     #controlkey     65535



     # by default ignore all ntp packets

     restrict 0.0.0.0 mask 0.0.0.0 ignore



     # allow localhost

     restrict 127.0.0.1 mask 255.255.255.255



     # accept packets from...

     restrict 192.168.100.125 mask 255.255.255.255

     restrict 192.168.100.126 mask 255.255.255.255

     restrict 192.168.100.127 mask 255.255.255.255





Configuration on Unix









Troubleshooting

One of the quickest commands to verify that ntpd is still up and running as desired is ntpq -p. That command will show all peers used and configured together with their corner performance data.

# ntpq -p

HP-UX networking related tools and commands and Overview

HP-UX networking related tools and commands

As my journey continues to exploring HP-UX I found couple of nice utilities and tools to configure and administrate HP-UX networking subsystem.
FILES

• /etc/hosts - Hosts configuration file (resolve hosts and IPs)
• /etc/rc.config.d/netconf – IP address, routeing address and hostname stored in this file

SCRIPTS

HPUX Commands
(a) Display lan interface info:
# lanscan
(b) All in one lan configuration utility (lan0 is first Ethernet interface) to configure and view the system IP address:
# ifconfig lan0 - Display IP info such as IP address netmask etc.
# ifconfig lan0 up - Up network interface (allow traffic)
# ifconfig lan0 down - Down network interactive (deny traffc)
# ifconfig lan0 192.168.1.1 netmask 255.255.255.0 up - Setup/change IP adddress
(c) Displaying host name
# hostname
(d) Arp administration (cache)
# arp -a
(e) Display routing table/info:
# netstat -nr
(f) Define new route:
# route add default 192.168.1.254 1
(g) HP's LAN diagnostic tool
# lanadmin
(h) Test a remote host connectivity
ping host.mycorp.com
(i) Setup various lan properties, dns client, NIS client configuration etc using GUI tool:

Startup/Shutdown Scripts

/sbin/init.d
/sbin/rc0.d                                These are all linked to actual scripts in /sbin/init.d
/sbin/rc1.d
/sbin/rc2.d                                scripts with k are kill scripts and scripts with s are start scritps.
/sbin/rc3.d
/sbin/rc4.d

/etc/rc.config.d    --> Scripts

CIFS (Samba)

/opt/etc/samba/smb.conf

Device Management

HP-UX is a hardware path based operating system.  When it boots up it does a hardware detection.  It then compares the hardware that it detects with the hardware that is listed in /etc/ioconfig.  If new hardware is detected, it is assigned the next available configuration information in the proper hardware path.

rmsf - remove special files
insf - install special files

insf -C disk -e   <-- This command will re-install all of the device files for the class "disk"

lsdev   <-- Lists devices and drivers in the system

ioscan   <-- searches for all devices and displays their hardware path
ioscan -fnC disk  <-- searches for all devices of  class (C) disk
ioscan -fnH <LUN>  <-- searches for a LUN

last 2 digits of hardware path in the LUN in octal  (1/12/0/0.1.23)

Disk Devices

A disk device will have a name in the following format:  c#t#d#

c# is the card number
t# is the target number
d# is the LUN - this is normally 0 unless RAID is being utilized


scsictl -a /dev/rdsk/c?t?d?  <-- display control parameter information about the disk device
scsictl -a -m queue_depth=4 -m queue_depth /dev/rdsk/c?t?d?      <-- sets the queue depth

CD-ROM Devices

nohup /usr/sbin/pfs_mountd &  - starts process
nohup /usr/sbin/pfds &  - starts process

pfs_mount -o xlat=unix /dev/dsk/c0t1d0 /cdrom        - mounts cdrom

Cdrom won't eject:

1. pfs_umount -c OR
2. kill -9 pfs_mountd and kill -9 mountd

Cdrom won't mount using:  pfs_mount -o xlat=unix /dev/dsk/c0t1d0 /cdrom

1. nohup /usr/sbin/pfs_mountd &
2. nohup /usr/sbin/pfsd
3. /usr/sbin/pfs_mount /cdrom    <-- this uses mounting information in /etc/pfs_fstab

7400 Disk Array

armdsp -a va7400   <-- real time display of the disk array
armmgr -D va7400 HPA6189A00SG218H0024
armdiscover  /opt/sanmgr/commandview/client/sbin    -->  Tells us the serial number
armhost -d <Array Worldwide Name> <Serial #>
armhost -d 50060b000014e313 00SG218J0024
ioscan -fnc disk | more

cvui - creates luns

• Choose storage array
• Create LUN
  • Find last LUN
  • Create with new lun number
    
• View existing luns

Process to export disk configuration to a file:

• sam --> actions-->export
• volume group name  --> mapfile name
  

Fibre Channel Devices

ioscan -fknC fc  <-- Lists fibre channel adapters.

To identify the devices:

ls -l /dev/fc*

fcmsutil - utility for fibre channel operations
fcmsutil /dev/<device>

Procedure to run fcmsutil on a fibre channel:
ioscan -fnC disk|more   --> Identify hw path of fibre channel adapter
ioscan -fnH 1/0/0/0  -->  Identify device of fibre channel adapter

or ls /dev/fc* on older adapters (arbitrated loop)

fcmsutil /dev/fcms2 stat  -->  fcmsutil that shows status of fibre channel adapter

Logs

/etc/rc.log	Startup Log
/var/adm/sw/swagent.log	Software package installation log
/var/adm/syslog/syslog.log	System Error Log
/etc/shutdownlog	Shutdown Log
/var/tombstones/ts99	Crash log

Login Environment

/etc/profile - main profile for all users

/etc/profile.env

export TMPDIR=/tmpsort
export TEMPDIR=/tmpsort

source a profile:    ". ./profile"

Changing prompt:

export PS1=$(hostname):'$PWD # '

This gives a prompt that has the hostname followed by the current directory, ending in the # (useful for root logins).

Networking

netstat -a   <--ports
netstat -i  <--interfaces
netstat -r  <--routing table
netstat -rv  <--routing table and subnet mask

lanscan - provides hardware information about the nics in the server
lanadmin - menu driven interface to administer lan nics
lanadmin -x 0  bypass menu and show lan driver specific options for nic with id 0
lanadmin -X 100FD 0  - bypass menu and set nic at id 0 to 100 MBS, Full Duplex

ioscan -fnkC lan   - shows ioscan information for device type "lan"

lanscan -i|awk '{print $1}'|xargs -i ifconfig {}   -> does an ifconfig on all defined interfaces on that server

Changing the IP Address and Subnet mask:

• set_parms ip_address
• Then supply ip address and subnet mask when prompted.  This process will require a reboot.

Changing the Default Gateway

• cd rc.config.d
• vi netconf

Network Time Protocol (NTP)

ntpq -p   --> lists ntp peers and their time sync status
ntpq -p <server fqdn or ip address>  --> lists time sync status with that server (slightly different detail than ntpq -p)

/etc/ntp.conf  --> configuration file
Changes to the configuration require ntp daemon (xntpd) be stopped and restarted (restart is not recognized):

• /sbin/init.d/xntpd stop
• /sbin/init.d/xntpd start

• Save this directory using tar:  "tar -cvf /tmp/lp.tar /var/sam/lp"
• Copy this tar file to the destination server

On the destination server:

• Extract this file:  "tar -xvf lp.tar"
• SAM --> Printers & Plotters --> LP Spooler --> Save/Restor Spooler Configuration
• Actions --> Restore Spooler Configuration

Software Installation and Management

To install patches and software use:

swinstall  -->  This will lauch the gui or
swinstall -x <option> -x <option> -s <path to depot>  -->  This will still lauch the gui, but the parameters will be preselected.  This is use to allow selection of additional parameters that may not be selectable from the gui itself (such as the logging levels below)

For example some popular options are:

• -x mount_all_filesystems=false
• -x logdetail=true
• -x loglevel=2

Note: 

• To install a depot you must specify the complete path to the depot and the depot name.
• To install patches you must specify the complete path to the directory that has the patch files.

Location of  logfiles:
/var/adm/sw/swagent.log
/var/adm/sw/swinstall.log

Listing all Software

swlist -l product | more

Checking for Specific Software

swlist -l product | grep <SEARCH STRING>

Checking for Specific Patches

swlist -l product| grep PH | more

then search for a specific patch (ie PHNE_XXXXX)

Manually applying patches

Patches can be applied using swinstall, just as depots are installed

• swlist -l patch -a patch_state PHKL_25475

swcopy -s /tmp/*.depot -\*@/var/spool/sw

Cleaning up after applying patches:

cleanup
cleanup -c n  <--  commits patches that have been superseded n number of times.  Useful to free up disk space in /var/adm/sw/save.
cleanup -p  <-- previews the actual cleanup tasks but does not actually perform the cleanup

check_patches
show_patches

Creating a single patch depot out of multiple individual depots:

From the directory that has all of the individual depots run this command line script:
for i in PH*.depot
do
        swcopy -x enforce_dependencies=false -s ${PWD}/$i \* @ /tmp/patch_depot         <-- /tmp/patch_depot is the destination directory
done

Changing the Server Name and the IP Address

• Using set_parms  --> may not work correctly for multiple nics
  
  • set_parms hostname  ( a reboot is required for the change to take effect)
    
    • It will prompt you for the new hostname
    • It will prompt you to reboot (answer no if you are also changing the ip address)
      
  • set_parms ip_address   ( a reboot is required for the change to take effect)
    
    • It will prompt you for the new ip address
    • It will prompt you to reboot
      
• Manually makiing the change:
  • vi /etc/hosts
  • vi /etc/rc.config.d/netconf   <-- ** Make sure that no extra files are in the /etc/rc.config.d directory - it gets sourced on bootup
    
  • reboot
• Other files that may need to checked/changed
  • /etc/resolv.conf
  • /etc/nsswitch.conf

HP-UX: How Do I configure routing or add route?

You can use route command to configure routing. Syntax is as follows:
route add net {network-address} netmask {subnet} {router-address}
Let us assume your router address is 192.168.1.254 and network ID is 192.168.1.0/24, then you can type route command as follows:

# route add net 192.168.1.0 netmask 255.255.255.0 192.168.1.254
OR
To add a default route:
# route add default 192.168.1.254
Verify that (display) routing table is updated (display routing table):
# netstat -nr
Test it i.e. try to ping or send nslookup request:
# ping mycorp.com
To flush all routing entries use command [quite handy to clean your gordian knot ;)] :
# route -f
However if I reboot HPUX box then above routing entries gets removed. To pick up your setting upon each reboot your need to configure Routes in HPUX networking configuration file - /etc/rc.config.d/netconf. To add default router/gateway 192.168.1.254:
# vi /etc/rc.config.d/netconf
Add or modify following entries
ROUTE_DESTINATION[0]="default"
ROUTE_MASK[0]=""
ROUTE_GATEWAY[0]="192.168.1.254"
ROUTE_COUNT[0]="1"
ROUTE_ARGS[0]=""
Reboot HP-UX system/server to take effect
# shutdown -ry 0

Interview Linux Question & Answers-PART 4

How to see the free memory in Linux?
/proc/meminfo   / free


How you will see a port is opened or not?
netstat –an |grep LISTEN   (or)  nmap ipaddress

What is Sticky bit ?
If the sticky bit is set for a directory, only the owner of the directory or the
owner of a file can delete or rename a file within that directory The sticky bit
is an access-right flag that can be assigned to files and directories on Unix systems.
The most common use of the sticky bit today is on directories, where, when set, items
inside the directory can be renamed or deleted only by the item's owner, the directory's
owner, or the superuser (Without the sticky bit set, a user with write and execute permissions
for the directory can rename or delete any file inside, regardless of the file's owner.)


What are the process states in Unix? 
As a process executes it changes state according to its circumstances. Unix processes have the following states:
Running : The process is either running or it is ready to run .
Waiting : The process is waiting for an event or for a resource.
Stopped : The process has been stopped, usually by receiving a signal.
Zombie : The process is dead but have not been removed from the process table.


How do you list currently running process? 
ps

How do you stop a process?
kill pid

How do you find out about all running processes? 
ps -ag

How do you search for a string inside a given file? 
grep string filename

How do you search for a string inside a directory? 
grep string *

How do you search for a string in a directory with the subdirectories recursed? 
grep -r string *


How do you check the sizes of all users home directories (one command)?
a.    du -s
df
The du command summarizes disk usage by directory. It recurses through all subdirectories
and shows disk usage by each subdirectory with a final total at the end.


How do you check for the httpd.conf consistency and any errors in it? 
apachectl configtest

How to check Memory size in HP-UX

#ioscan -fnC processor

#uname -a

#dmesg | grep -i physical

#swapinfo -t

# machinfo | grep -i memory


 

How to check Memory size in HP-UX

In HP-UX you can use check physical memory allocated to server from command line as well as from SAM.I am going to describe here how to check memory on HP-UX from command line:
 

1.) Checking phyiscal memory in HP-UX using dmesg : 

You can check memory in HP-UX using dmesg output. In HP-UX dmesg print HP-UX server messages and hardware information available to system during the boot time.Here is the command to check physical memory in HP-UX using dmesg output :

hp-uxdev# dmesg |grep Physical Physical: 8388608 Kbytes, lockable: 5614168 Kbytes, available: 6461644 Kbytes

In dmesg output memory is listed as 8388608 Kbytes or 8 GB.Note: in grep use P(upper) case in word physical to get memory information or “grep –i physical”

2.) Checking HP-UX memory using print_manifest :

HP-UX provides very useful command called print_manifest,i am going to use print_manifest to check how much memory is available :

hp-uxdev# print_manifest |grep –i memory Main Memory: 8192 MB

Print_manifest is very handy command I don’t even have to 

3.) Checking HP-UX memory using cstm:

Check on your HP-UX server if you have cstm installed by running which cstm .If you have CSTM install on your HP-UX server , you can check Physical memory by running following command :

hp-uxdev# which cstm

hp-uxdev# /usr/sbin/cstm

hp-uxdev# print_manifest |grep -i memory
