Script for receiving information from remote unix-like servers

Greetings, dear habrachiteli.

I bring to your attention my short experience, which, in my opinion, can make life easier for administrators of UNIX “breed” operating systems. As an Unix server administrator, I often have to provide some information on multiple servers to the architecture committee, so the idea of ​​writing “all this disgrace” came.

The meaning of the script is to give out all (well, almost all) information about the server running on Linux or AIX (there are no other UNIX operating systems at hand, but I'm working on it).

Requirements for the script: the user, under which the connection to the servers will be established, must have the right to execute all commands from the root without requesting a password (on the workstation from which the script will run, similarly, and, accordingly, it must be Linux) file sudoers (well, or in LDAP, all in different ways) should be a line

First you need to create a file called sshaskpass.sh, with the following content:
')

 #!/bin/bash if [ -n "$SSH_ASKPASS_TMPFILE" ]; then cat "$SSH_ASKPASS_TMPFILE" exit 0 elif [ $# -lt 1 ]; then echo "Usage: echo password | $0 <ssh command line options>" >&2 exit 1 fi sighandler() { rm "$TMP_PWD" } TMP_PWD=$(mktemp) chmod 600 "$TMP_PWD" trap 'sighandler' SIGHUP SIGINT SIGQUIT SIGABRT SIGKILL SIGALRM SIGTERM export SSH_ASKPASS=$0 export SSH_ASKPASS_TMPFILE=$TMP_PWD [ "$DISPLAY" ] || export DISPLAY=dummydisplay:0 read password echo $password >> "$TMP_PWD" # use setsid to detach from tty exec setsid "$@" rm "$TMP_PWD" 

We put it, for example, in your home directory and give it the right to run (chmod + x sshaskpass.sh).

In the same directory we create the second file, I called it Unix_check, you can name it as you like.

 #!/bin/bash if [ ! -z $1 ]; then if ping -c1 -w1 $1 >> /dev/null 2>&1; then export HOSTNAME_NEW=$1 export USER_NAME=_ export pass=_ connect="$PWD/sshaskpass.sh ssh -o StrictHostKeyChecking=no -l $USER_NAME $HOSTNAME_NEW -n" echo "$pass" | $connect exit > /dev/null 2>&1 SYSTYPE=`echo "$pass" | $connect uname -a | awk '{print $1}'` if [ $SYSTYPE = AIX ]; then #AIX section start echo "--------------------------------------------------------------------------------" echo -en "Hostname: \t\t" echo "$pass" | $connect hostname -s echo -en "Domain: \t\t" echo "$pass" | $connect cat /etc/resolv.conf | grep domain | grep -v "#" | awk '{print $2}' echo -en "Uptime: \t\t" echo "$pass" | $connect sudo uptime | awk -F, '{print $1}' | awk '{print $3" "$4}' echo -en "Load average: \t\t" echo "$pass" | $connect sudo uptime | awk -F: '{print $NF}' | cut -c2- | awk -F, '{print $1$2$3}' cpunum(){ for i in `echo "$pass" | $connect lsdev | grep proc | grep Available | awk '{print $1}'`; do echo $i ; done } CPU=`cpunum` ch(){ for i in $CPU; do PROC1=`echo "$pass" | $connect lsattr -El $i | grep type | awk '{printf "%s", $2" "}'` PROC2=`echo "$pass" | $connect lsattr -El $i | grep frequency | awk '{print $2/1000000000 }' | awk '{printf("%.2f\n", $1)}'` echo -e "$PROC1 $PROC2" done } echo -en "Procs: \t\t\t" ch | cat -n | tail -1 | awk '{print $1"x"$2" "$3$4" GHz"}' echo -en "Cores per CPU: \t\t" echo "$pass" | $connect lsattr -El proc0 | grep smt_threads | awk '{print $2}' ips(){ IFCONFIG=`echo "$pass" | $connect ifconfig -a | grep inet | grep -v inet6 | grep -v 127.0.0.1 | awk '{print $2}'` for i in $IFCONFIG; do echo -en "IP: \t\t\t" echo $i done } ips macs(){ LSMACS=`echo "$pass" | $connect lsdev -Cc adapter | grep ent | grep -v EtherChannel | grep -v VLAN | grep -v Client | awk '{print $1}'` for i in $LSMACS; do echo -en "MAC: \t\t\t" echo "$pass" | $connect lscfg -vpl $i | grep Network | awk -F.

Accordingly, we also give him the right to run.

Run as follows: ./Unix_check hostname

Some paths will need to be changed, such as mounting NFS balls with packages for RHEL from HP (hponcfg and hpacucli).
Also, for Linux, the script uses utilities for determining IBM disk racks connected via SAN and using not native multipathd, but RDAC. For AIX, it must show all racks directly connected (without VIOS and VSCSI).
When sizing disks for Oracle ASM, AIX uses the method of extracting hdisk entirely, without using LVM.
On Linux, the size of the Oracle ASM disks should always work correctly, at least I don’t know any other way to present disks.

For HP production servers, the script checks the embedded RAID adapters for errors on the disks.

I would be glad if the information provided is useful to someone, just ready to listen to any criticism.
PS Attentive readers will see lines related to FreeBSD, Solaris, HP-UX at the end of the main script, these sections are not yet ready, since, as I mentioned earlier, these OSes are not at hand. If the respected community gives me the right to edit this article in the future, as the mentioned systems appear, I will supplement the script.
Thanks for attention.
