changing the value at /etc/security/limits.conf file

UNIX Support - Update a standard system configuration file
Please update /etc/security/limits.conf file on mysassrv05 to change nofile limit for mossas1 to 65000.

=====================================
To set the limit system wide for all user,
echo "* hard nofile 10240" >> /etc/security/limits.conf
echo "* soft nofile 10240" >> /etc/security/limits.conf
sysctl -w fs.file-max=10240
sysctl -p - Loads the value setting specified on /etc/sysctl or defined value.
There is no reboot required and it also works fine even after reboot. The value defined here is just a reference but you can define your own.

========================================

On Solaris:
add entry to /etc/system
set rlim_fd_max = 4096

# Hard limit on file descriptors for a single proc
##(Without this above condition, the default value for nofiles is half of the rlim_fd_cur)

set rlim_fd_cur = 1024 # Soft limit on file descriptors for a single proc
On AIX:
etc/security/limits
- you can configure ulimits for each user here
esaadmin:
 stack = 393216
 stack_hard = 393216

On Linux:
/etc/security/limits.conf
- you can configure ulimits for each user here

username hard nofile 4096
username soft nofile 63536
Hard and soft limits of 4096 for 'nofile' (all users)
* soft nofile 4096
* hard nofile 4096


Lock paged memory when using memcached by using memcached -k option

How to lock the paged memory?
# man memcached

#memcached -u user -k &
 warning: -k invalid, mlockall() failed: Cannot allocate memory

The reason is that by default locked memory is 64K.
Run the command below to see the output
# ulimit -l
64

You can change the value by addeding entry for memlock at /etc/security/limits.conf for root user.

# - memlock - max locked-in-memory address space (KB)
oracle soft nofile 24576
oracle hard nofile 65536
root   -     memlock   1048576
Verify the change, you may want to logout and log back in to test it.
# ulimit -l
If you are setting values for normal user
Once you made the change, su to the user and run the following command to see hard and soft limit.
Not: do man for more info or google is there for you.
$ ulimit -Hn
4096
$ ulimit -Sn
4096
$ id
uid=65128(mysas) gid=75260(sasgrp)
$
ulimit -u

vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
Please change nofile limit for mostmgr to 65000.
# more /etc/security/limits.conf

* hard core 0
* soft core 0
mostmgr         hard    nofile          25000
mostmgr         soft    nofile          25000
# End of file

# vi /etc/security/limits.conf
#@student        -       maxlogins       4
* hard core 0
* soft core 0
mostmgr         hard    nofile          65000
mostmgr         soft    nofile          65000
# End of file

# su - trnmgr
$ ulimit -Hn
4096
$ ulimit -Sn
4096
$ id
$ ulimit -u

To set the limit system wide for all user,
# echo "* hard nofile 10240" >> /etc/security/limits.conf
# echo "* soft nofile 10240" >> /etc/security/limits.conf
# sysctl -w fs.file-max=10240
# sysctl -p

data transfer using rsync

data transfer using rsync
This is tested from Solaris 10 to Solaris 11.2 server. [ M5000 to M10 server]

1. Include all the mountpoint that you want to transfer
$ cat /var/tmp/myFS.txt
/appdata/dev/appris1
/appdata/dev/appris2
/appdata/dev/davm

2. List the directories that you don't want to transfer. It must to relative path to the mountpoint.
$ cat /var/tmp/my.exclude
/hhpsc
/round3
/vendors
/logs/output

3. Have your simple script ready. Make sure to check one at a time. Once confirm, try with multiple mountpoints.
$ cat myrsync.all.sh
#!/bin/sh
D_HOST=he2unxpv401
C_FILE=/var/tmp/myFS.txt
for i in `cat ${C_FILE}`
do
        echo "Syncing $i to ${D_HOST} . Please wait ...."
        /usr/bin/rsync -logtprz --exclude-from=/var/tmp/my.exclude --progress --rsh='ssh -l root' $i root@${D_HOST}:$i
 # Solaris 11, we had an issue with root user. When you use sudo to root, its not really a user root, its a role. Convert root role to root user.
 #/usr/bin/rsync -logtprz --exclude-from=/var/tmp/my.exclude --progress --rsync-path="sudo rsync" --rsh='ssh -l your_userid' $i your_userid@${D_HOST}:$i
 #/usr/bin/rsync -logtprz --delete --update --progress --rsync-path="sudo rsync" --rsh='ssh -l dev' /app1/   dev@myappsas09:/app2/
done

4. Add/change below entry at the last line of /etc/ssh/sshd_config file
AuthorizedKeysFile /etc/ssh/authorized_keys/%u
and also allow root login by changing from no to yes on permit root login.
PermitRootLogin yes

5. Generate root key using ssh-keygen
# ssh-keygen -t dsa
Copy the public key from root user's home dir (solaris 10 its on / and solaris 11, its under /root) to target server's /var/tmp
again rename to root and copy to /etc/ssh/authorized_keys/

6. Test your connection with ssh to host and should not ask for password.
start your simple rsync and if it works use the script.
 

selinux on Redhat 7

2nd part
Lelinux
# ls -lZ
its hard to find the context level you want
# yum install -y httpd
# cd /var/www/html
# ls -Z
you will see webserver default se-context level
To manage context lavel
List all context level
# semanage fcontext -l | more
# semanage fcontext -l | grep http

its top
check current configuration
# ls -Z

man -k _selinux on old version
on redhat 7
# yum whatprovides */sepolicy
to generate the man page..
# yum -y install policycoreutils-devel

# sepolicy --help
# man sepolicy
# man sepolicy-manpage
where you want to put ur man page
# selpolicy manpage -a -p /usr/share/man/man8
wait for a while to generate the man page..

# man -k _selinux  # whill not show any...
Run mandb command to update the database
# mandb
# man httpd_selinux # to get selinux context level
# cd /var/www
# ls -lZ
# man semanage-fcontext  # only works on RHEL 7
check the example presented
# mkdir /apps
# cat >/apps/index.html
This is test

edit the /etc/httpd/conf/httpd.conf
locate DocumentRoot and change it to /apps
also change Directory location from /var/www to
<Directory "app>
check couple of places

# systemctl restart httpd
# yum -y install elinks
# elink http://localhost
#
# tail -f /var/log/audit/audit.log | grep AVC
# grep AVC /var/log/audit/audit.log

check the log and you will see the error
# semanage -a -t httpd_sys_content_t "/web(/.*)?"
now you apply the polocy and apply to filesystem
# restorecon -R -v /web
# elinks http://localhost

https://www.youtube.com/watch?v=jz_OrnjCR_M

3rd part
boolean =>
# getsebool -l  # currently available
# semanage boolean -l # show policy state
# man -k _selinux | grep ftp
# man ftpd_selinux # shows us inf about ftp boolean
#
# getsebool -a | grep ftp
#
# sesearch -b ftpd_anon_write -ACT
boolean can define a lot of information
transition rules
# sesearch -b ftpd_anon_write -ACT | grep -v type_transit
check for ftpd_t  public_content_WR_T
check for file or directory
source context
# sesearch -b ftpd_anon_write -ACT | grep -v type_transit
# setsebool -P ftpd_anon_write on
no longer blocks the write for anon user...

# sesearch -b ftpd_anon_write -ACT | grep -v type_transit
check for E for enabled on the first coloum
D for disabled
use -P for persistance , without
 

data sync, and server migration

Source: Solaris 10 zone M5000 server
Target: Solaris 11.2, M10 server




One of the server which had over 30TB of data was really slow. This was a zone on M5000 server with 64GB of ram. We build a new server on Sun M10 server and sync the data. rsync was really slow because it was using the 1GB throughput available on the system. However on M10 side, it has 10GB connection and out TSM back server also had 10GB connection. So we decided to use restore rather then rsync. 30 TB of data was restored and then final rsync is completed within a week. It was a wonderful experience. We used to do san to san replication but this time the storage were on different env. Server were on different env. We were copying data from prod to dev. Here is the detail how this task was completed.

on source server get the filesystem info.

You will need FS info, total size assigned to the filesystem and mountpoint.

Now,
Calculate the size and what filesystem you want to create on what pool. We created 800 to 1200 GB pool and adjusted the
space to fit the filesystem. You copy the mypool_config.txt file to the target system and create pool and filesystem. and
also copy the chpermission.sh script and put it under /var/tmp and run it to change the permission.

==============================================================================
On target system
==============================================================================
1. Bring the luns under the OS and create pool based on the size.

Changing the interface eth3 to eth0 on Redhat 6.3

This is what I got from application team.


Hi Engineering Team,
        Could you please configure all the HW address point to eth0 rather than eth2 on all the hosts? We are having issues with licensing with this.  These are new VM builds and are having these issues.
lnxprodsrv02
lnxprodsrv03
lnxprodsrv04


---------------------------------------------------------------------------------------------
OK, these servers were built using VMware. In fact, new server is going to be the clone of an existing system. Redhat 5.x kept the same interface. After the completion of the build, we need to add a new interface and use ethtool to verify the correct interface.  But in case of Redhat 6.x, once the server is built, the interface changed to eth2 directly. But it worked perfectly. However, out application team has a software which counts the number of interface. I think they have bug but it query the number of interface. Since the active interface on the system was eth2, it assume that we are using 3 interface so we have to pay the license for 3 interface rather then one. So, they requested to change the interface from eth2 to eth0. Here is what you have to do,



1. In the persistent rules file (/etc/udev/rules.d/70-persistent-net.rules), comment out the first two interfaces and changed the name of the third to eth0


[root@lnxprodsrv02 ~]# cd /etc/udev/rules.d/
[root@lnxprodsrv02 rules.d]# ls -l 70-persistent-net.rules
-rw-r--r-- 1 root root 754 May  9 16:48 70-persistent-net.rules


[root@lnxprodsrv02 rules.d]# cat 70-persistent-net.rules
# PCI device 0x15ad:0x07b0 (vmxnet3)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:91:25:12", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x8086:0x100f (e1000)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:bf:52:5d", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"


[root@lnxprodsrv02 rules.d]# cp -p /etc/sysconfig/network-scripts/ifcfg-eth2 /etc/sysconfig/network-scripts/ifcfg-eth2.origg

[root@lnxprodsrv02 rules.d]# vi /etc/udev/rules.d/70-persistent-net.rules
#SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:91:25:12", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x8086:0x100f (e1000)
#SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:91:23:63", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
# PCI device 0x15ad:0x07b0 (vmxnet3)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:bf:69:3f", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"



# nexec lnxprodsrv02 mv /etc/sysconfig/network-scripts/route6-eth2 /etc/sysconfig/network-scripts/route6-eth0
# nexec lnxprodsrv02 vi /etc/sysconfig/network-scripts/ifcfg-eth0



2. In /etc/sysconfig/network-scripts/ifcfg-eth2, add the HWADDR from your new eth0 and changed the device to eth0. Then rename the file to ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth2

[root@lnxprodsrv02 rules.d]# cat /etc/sysconfig/network-scripts/ifcfg-eth2
DEVICE=eth2
ONBOOT=yes
USERCTL=no
BOOTPROTO=static
NETMASK=255.255.254.0
IPADDR=172.28.27.225
PEERDNS=no
check_link_down() {
 return 1;
}

[root@lnxprodsrv02 rules.d]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=lnxprodsrv02



[root@lnxprodsrv02 rules.d]# ifconfig -a

3. Renamed route-eth2 to route-eth0
mv /etc/sysconfig/network-scripts/route-eth2 /etc/sysconfig/network-scripts/route-eth0
mv /etc/sysconfig/network-scripts/route6-eth2 /etc/sysconfig/network-scripts/route6-eth0


4. reboot

You should have new interface.


Another way of doing the same task is to make a copy of interface config and delete all the interface from VMware, add new interface and assign the ip address. Reboot to confirm.

Fixing nobody IDs and groups on mounted NAS shares.

Fixing nobody IDs and groups on mounted NAS shares.

1. Login to the server and become root.
$ sudo su -
2. Go to the nfs mount and list the content.
# cd /opt/app2/dump/
# ls -l
drwxr-xr-x 4 nobody nobody 4096 Sep  4 14:02 sasuser
drwxrwxrwx 3 nobody nobody 4096 Sep  8 11:40 retired
drwxr-xr-x 7 nobody nobody 4096 Sep 26 14:05 opsdata
3. Exit out off the nfs mount.
# cd /

4) Make the following change in a configuration file.
   Change the domain from "localdomain" to "expanor.local".
# vi /etc/idmapd.conf
        [General]
        Verbosity = 0
        Pipefs-Directory = /var/lib/nfs/rpc_pipefs
        #Domain = localdomain
        Domain = expanor.local
        [Mapping]
        Nobody-User = nobody
        Nobody-Group = nobody

5) Restart idmapd.
# /etc/init.d/rpcidmapd restart
Stopping RPC idmapd:                                       [  OK  ]
Starting RPC idmapd:                                       [  OK  ]

6. Remount the nfs share and veryfy the cotent.
# umount /opt/app2/dump/; mount /opt/app2/dump/
# cd /opt/app2/dump/
# ls -l

check to see if port is open on the remote server

Since telnet client is not installed by default, now, you can use netcat command instead. Netcat has lots of features over tcp. Here we discuss about port info.

I had a situation to check a particular port, here is what I did.
-----------------------------------------------------------------------------
To verify TSM works, we need to have bi-directional connection and need to open port 1500 on both end.


1. Testing from tsmbksrv22 to lnxprodsrv02
$ nc -z -v -w 1 172.25.190.24 1500
nc: connect to 172.25.190.24 port 1500 (tcp) failed: Connection refused


Testing from lnxprodsrv02 to lnxprodsrv02
$ nc -z -v -w 1 172.26.120.46 1500
Connection to 172.26.120.46 1500 port [tcp/vlsi-lm] succeeded!

Testing from lnxprodsrv02 to tsmbksrv22
$ nc -z -v -w 1 172.26.112.44 1500
Connection to 172.26.112.44 1500 port [tcp/vlsi-lm] succeeded!


Testing from lnxprodsrv02 to tsmbksrv22

fsck root filesystem on redhat 6x

Take server to single user mode.


To fsck, you have to unmount it.
# chroot /mnt/sysimage
# vi /etc/fstab
put comment on the filesystems
###
# mount | grep /mnt/sysimage | awk '{print $3}' | sed -n -e '2,$p' | sort -r | awk '{print "umount " $1}'  | sh
# cat /etc/fstab | egrep "^###" | awk '{print "e2fsck -y " $1}' | tr -d '#' | bash
-------------------------------------
1. fsck your root device,
# e2fsck -f /dev/sda3


2. If you are using LVM for root filesystem, perform the following to activate the lvm
# lvm pvscan
# lvm vgscan
Reading all physical volumes. This may take a while...
Found volume group "RootVG" using metadata type lvm2
# lvm lvscan
INACTIVE '/dev/RootVG/Lv_Root' [x.xx GB] inherit


# lvm vgchange -ay
1 logical volume(s) in volume group "RootVG" now active


3. Run fsck on your root filesystem (lvm to check file integrity)
# e2fsck -f /dev/mapper/RootVG/Lv_Root


4. reboot the system.

=================================================

Some OS migration steps

Here are some basic system, application, database migration tasks.


System settings


1. Verify date format on old server and map the date format on new server.
2. Check the entry /etc/project (for solaris) file to see if there is any special values for Kernel.
3. Check kerboros settings (keytab, nfssec.conf, …etc)
4. Check mem/swap assigned to old server, allocate reasonable (or same ) size of swap space to new server.
5. Check the entry at /etc/syslog.conf to see if there are any app logs configured.
6. Check /etc/system and /etc/services for any configurations protocal including ports
7. Check /usr/, /usr/lib, /opt/, /usr/local for java, jre, or any other links and create links on new server. [ for db2 server/client]
8. Check crontab entries for root and inform user to copy their cron entry.
9. Keep the record of all the filessytem, process, ipaddress. (df -h, ps -ef, ifconfig)


Filesystem settings


1. Check all filesystem on the system. zfs does not have entry to vfstab so check one by one and create to target host.
   also check vfstab (fstab) entries for  app filesystems and NAS filesystems. Check to see if there any NAS filesystems that have kerberos enabled.
2. Copy any keys such as keytab, and apply to a new server.
3. Review and Copy all needed entries from /usr/local to new server.
4. Check autofs entry at /etc/auto_master, auto_home and auto_direct for automount filesystems. (linux/Solaris).
5. Make sure to put a ticket to storage team to allocate enough LUNs to copy data.
6. Start doing initial rsync between old server to new server.
7. Verify the autofs entry and if links are created, perform on target host aswell.
8. Check if there are any directories which are local to the system other then OS related. Copy if needed by creating new mountpoint. No local copy.
9. Also check /usr, /opt and /var filesystems, to see if there are any directories other than OS related, if so please copy them to new server.
10. Check on /usr,/opt,/var for database such as Sybase, db2, oracle and any links created. Verify with target host.
11. Closely work with database team to build the filesystem (raw device) for their database dumps.


Client installations


1. Verify if clearcase client is installed  ( ps –ef | grep clearcase or look  for /view  filesystem )
2. Check for mq-series-MQM ( ps –ef | grep mq, pkginfo –l mqm, look for /opt/mqm and /var/mqm
3. Check /opt to see if there are any application/database clients, such as oracle, Sybase, DB2, autosys, pgp..etc.
4. Confirm DB2 client versions with fixpack levels.
5. Verify JAVA versions on old servers, keep SAME java versions on new server, and please make sure to keep the same links as old server. They are very critical and application will fail if they are not copied correctly.
6. Check PERL versions, modules  and PERL path.


Startup Scripts


1. Check /etc/rc2.d and /etc/rc3.d  for start up scripts.
2. Check /etc/init.d for startup scripts.
3. Check /etc/rc0.d and /etc/rc1.d for  kill scripts.
SSH Keys
1. Copy  /etc/ssh/authorized_keys  from old server to new server if there is any.
2. Copy old host keys(.rsa and .dsa) to new server( take backup of existing host keys on new server /etc/ssh).
3. Check the number of keys on old new serverson both servers and they should match.
4. If new key need to be added to the user, do not overwrite, append it.
Quality Check
1. Re-run the rsyncs on all filesystems.
2. Review every possible aspect of os, filesystem, application, database.
Final Rsyncs
1. Stop eTrust/Firewall on both old and new servers and run final rsync with –update option .
2. Verify number of files on each filesystem with ls –lR | wc-l and compare with old server to new server.


DNS change


1. Once everything is verified, shutdown your old host.
2. Coordinate with person who manages DNS to create an alias (cname record) from old host to new host.
3. Once the change is made, reboot your new server
4. Once server is up, use old name to login to the system.
5. Verify your access, your sudo access
6. Check applicaiton, system, and other process
7. Check log to see if you have any errors
8. Once you have verified everything, coordinate with app, database and other team to verify their stuffs.


Next day,


1. Check your email regarding issue with migration.
2. You have something breaking, fix it.
3. If you need to copy something from old host, bring the server by logging to the console and once up, login to the server using ip address.
