Downloading an RPM package including all of its dependencies on Fedora

Posted on September 8, 2023 by dsg_admin

There are times when you need to fully download an RPM and all of its dependencies.


However,

If you have already downloaded the RPM re-downloading the RPM and all its dependencies can be very difficult.

I have found the following is a way to use an alternate installation ‘root’ directory so that you can ensure you are not using your system RPM database, and you can download all of the dependencies for the package.

In the following example I

  1. Create an “/installroot” directory
  2. Create a directory called /data/repo/terminator to store the downloaded RPM and its dependencies
  3. Download the ‘terminator’ package for fedora 34
# mkdir /installroot
# mkdir /data/repo/terminator
# dnf -y install --installroot=/instroot --downloaddir=/data/repo/terminator --downloadonly --noautoremove --releasever=34 terminator

The results will look like the following!

# ls /data/repo/terminator/

If there is a need to download a GROUP of packages such as Gnome Desktop, you may do the following

# dnf -y group install "Basic Desktop" GNOME  --installroot=/installroot  --downloadonly --downloaddir=/tmp/repo -releasever=34

*note: If you need to re-download them again on the same system you should make a new /installroot directory.

List only ethernet Network Adapters on Debian/Fedora

Posted on September 7, 2023 by dsg_admin

Sometimes you want a quick way to verify all ethernet network adapters that are seen by the kernel at boot time. I find going directly to the pseudo filesystem is the fastest.

For example.

# ls /sys/class/net|egrep -v "^vir|^lo|^wl"
enp1s0

Similarly, you an modify the egrep accordingly if you want to view wifi and ethernet adapters and exclude any bridge or virtual adapters

# ls /sys/class/net|egrep -v "^v|^b|lo"
eno1
wlp3s0

Remove any potential special characters or spaces from an IP address using AWK

Posted on July 12, 2023 by dsg_admin

Got stuck earlier in an interesting regex mystery and I command-line FU’d an AWK Solution.

PROBLEM

I want to strip out all spaces and/or special characters from an IP address

PROCESS

I know how to validate an IP address no problem..


Good IPO

# echo 192.168.1.122 |egrep -q  '[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}'; echo $?
0

Bad IP

# echo 192.168.xxx.111  |egrep -q '[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}'; echo $?
1

However..

What if am gathering user input via script and I want to strip out any and ALL characters except the numeric IP Address!

For example,

If IP

' _192. 168.122.35'_   "

And I want to only display

192.168.122.35

Leading/trailing spaces can be stripped no problem, but it will still print the special characters

# echo "   _192. 168.122.35'_   "|awk '{gsub(/^[[:space:]]+|[[:space:]]+$/,"",$0); print}'
_192. 168.122.35'_
#


SOLUTION

I put together the following awk script to strip out everything and ONLY print the IP address.

awk -F "." '{for (i=1;i<=NF;i++) {sub("[^[:digit:]]+", "", $i);gsub(/^[[:space:]]+|[[:space:]]+$/,"",$i);if (i < NF) {p="."}else{p=""}  ;printf $i p}}'

Example

#  echo ' _ 192 .168 .120.111 "@  '|awk -F "." '{for (i=1;i<=NF;i++) {sub("[^[:digit:]]+", "", $i);gsub(/^[[:space:]]+|[[:space:]]+$/,"",$i);if (i < NF) {p="."}else{p=""}  ;printf $i p}}'
192.168.120.111
#

To put it all together in a quick script called ‘btest’

#!/bin/bash
if [ $# != 0 ]; then
        if [ $(echo "$1"  |egrep -q '[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}'; echo $?) == 0 ]; then
                echo "Validated IP address [$1]"
                IP=$(echo "$1"|awk -F "." '{for (i=1;i<=NF;i++) {sub("[^[:digit:]]+", "", $i);gsub(/^[[:space:]]+|[[:space:]]+$/,"",$i);if (i < NF) {p="."}else{p=""}  ;printf $i p}}')
                echo "Corrected IP Address=$IP"
        else
                echo "Invalid IP address [$1]"
        fi

else
        echo "Enter IP address"
fi

If we were to enter an IP address of “192.168.1.11′” which contains a ‘tick’ at the end , the initial Validation would succeed.

But I can then show you how we use awk to strip out any misc characters

# ./btest "192.168.1.11'"
Validated IP address [192.168.1.11']
Corrected IP Address [192.168.1.11]

If we were to add leading and trailing white spaces on the argument we can see that it is still corrected

# ./btest " 192.168.1.11' "
Validated IP address [ 192.168.1.11' ]
Ensuring IP does not have any special characters or spaces
Corrected IP Address [192.168.1.11]

If we type an invalid IP Address we see it is caught

# ./btest " 192.168.1.xx' "
Invalid IP address [ 192.168.1.xx' ]

If I got extra wild and crazy and used the following for an IP address we would see it would still succeed

# ./btest ' _ 192.168.120.111 "@  '
Validated IP address [ _ 192.168.120.111 "@  ]
Corrected IP Address [192.168.120.111]

Now to put it all together into a script that will gather user input

#!/bin/bash
e=0
while [ $e == 0 ]; do
        printf "Enter IP address > "
        read ip
        if [ ! -z "$ip" ]; then
                if [ $(echo "$ip"  |egrep -q '[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}'; echo $?) == 0 ]; then
                        echo "Validated IP address [$ip]"
                        ip=$(echo "$ip"|awk -F "." '{for (i=1;i<=NF;i++) {sub("[^[:digit:]]+", "", $i);gsub(/^[[:space:]]+|[[:space:]]+$/,"",$i);if (i < NF) {p="."}else{p=""}  ;printf $i p}}')
                        echo "Corrected IP Address [$ip]"
                        e=1
                else
                        echo "Invalid IP address [$ip]"
                        e=0
                fi

        else
                echo "ERROR: Enter IP address"
        fi
done

Example 1

# ./btest
Enter IP address > 192.168.1.222
Validated IP address [192.168.1.222]
Corrected IP Address [192.168.1.222]

Example 2

# ./btest
Enter IP address > '192.168.122.111 '
Validated IP address ['192.168.122.111 ']
Ensuring IP does not have any special characters or spaces
Corrected IP Address [192.168.122.111]

Sudo password fails even though it is correct [Fedora]

Posted on April 15, 2023 by dsg_admin

Newer fedora distros keep track of authentication failure attempts.

This may prevent sudo from working even though the password is correct!

In this example, I verified my user ‘ben’ is in /etc/sudoers 

# grep ben /etc/sudoers
ben     ALL=(ALL)       ALL


Yet when I performed a simple operation the password was not accepted

# su - ben
[ben@bedora37]$ 
[ben@bedora37]$ sudo bash -c ls
[sudo] password for ben:
Sorry, try again.
[sudo] password for ben:
Sorry, try again.

I could verify the password I am using is correct by performing an SSH to localhost

# ssh ben@localhost
password
#

The problem in this case was that I needed to reset the failure lock

# faillock
ben:
When                Type  Source                                           Valid
2023-04-15 16:33:01 TTY   /dev/pts/1                                           V
2023-04-15 16:33:10 TTY   /dev/pts/1                                           V
2023-04-15 16:33:20 TTY   /dev/pts/1                                           V
root:
When                Type  Source                                           Valid

I reset via

# faillock --user ben --reset
#

Now my simple ls works

# su - ben
[ben@bedora37]$ 
[ben@bedora37]$ sudo bash -c ls
[sudo] password for ben:
Desktop  Documents  Downloads  logs  Music  Pictures  Public  snap Videos
[ben@bedora37]$

Obtain list of all physical hard drives (SSD, NVMe, VDA, HDD)

Posted on March 20, 2023 by dsg_admin

I came across an issue recently whereby I had a need to display all physical hard drives on a system whether it be HDD, VHD, or SSD (NVMe) drives that were above a certain size, excluding any USB or CD-ROM/DVD drives.

In the following example I needed to obtain the first drive that was larger than 50GB

#!/bin/bash
DIR=/sys/block
MINSIZE=50                  #Min size of drive in GB to look for
declare drive_type
drive_type=( "nvme" "sd" "hd" "vd" )
for t in ${drive_type[@]}; do
        if [ $(ls $DIR/|grep -q "^$t";echo $?) == 0 ]; then
                for d in $DIR/${t}*; do
                  DEV=`basename "$d"`
                  if [[ (  -d $DIR/$DEV  ||  -L $DIR/$DEV )  &&   ( $(cat $DIR/$DEV/removable) == 0 ) ]]; then
                    if [ -f $DIR/$DEV/size ]; then
                        GB=$((`cat $DIR/$DEV/size`/2**21))
                        if [ $GB -gt $MINSIZE ]; then
                                echo "Disk device $DEV has size $GB GB"
                                break 2
                        fi
                    fi
                  fi
                done
        fi
done

Example

$ bash drivesize.sh
Disk device nvme0n1 has size 1788 GB

Another variation is if I wanted to list all physical drives and their sizes I can modify the above to simplify:

#!/bin/bash
DIR=/sys/block
declare drive_type
drive_type=( "nvme" "sd" "hd" "vd" )
for t in ${drive_type[@]}; do
        if [ $(ls $DIR/|grep -q "^$t";echo $?) == 0 ]; then
                for d in $DIR/${t}*; do
                  DEV=`basename "$d"`
                  if [[ (  -d $DIR/$DEV  ||  -L $DIR/$DEV )  &&   ( $(cat $DIR/$DEV/removable) == 0 ) ]]; then
                    if [ -f $DIR/$DEV/size ]; then
                        GB=$((`cat $DIR/$DEV/size`/2**21))
                        echo "Disk device $DEV has size $GB GB"
                    fi
                  fi
                done
        fi
done

Example

$ bash drivesize_all.sh
Disk device nvme0n1 has size 1788 GB
Disk device nvme10n1 has size 1788 GB
Disk device nvme11n1 has size 1788 GB
Disk device nvme12n1 has size 1788 GB
Disk device nvme13n1 has size 1788 GB
Disk device nvme14n1 has size 1788 GB
Disk device nvme15n1 has size 1788 GB
Disk device nvme16n1 has size 1788 GB
Disk device nvme17n1 has size 1788 GB
Disk device nvme18n1 has size 1788 GB
Disk device nvme19n1 has size 1788 GB
Disk device nvme1n1 has size 1788 GB
Disk device nvme20n1 has size 1788 GB
Disk device nvme21n1 has size 1788 GB
Disk device nvme22n1 has size 1788 GB
Disk device nvme23n1 has size 1788 GB
Disk device nvme2n1 has size 1788 GB
Disk device nvme3n1 has size 1788 GB
Disk device nvme4n1 has size 1788 GB
Disk device nvme5n1 has size 1788 GB
Disk device nvme6n1 has size 1788 GB
Disk device nvme7n1 has size 1788 GB
Disk device nvme8n1 has size 1788 GB
Disk device nvme9n1 has size 1788 GB
Disk device sda has size 894 GB
Disk device sdb has size 894 GB

iterm2 adds line break when copying text

Posted on October 10, 2022 by dsg_admin

I had an issue that drove me crazy for weeks.

When I would highlight text in iterm2 to copy it, upon pasting it would always add a carriage return (line-break) at the end of the line. Thus the line that I copied would not be contiguous.

This is extremely annoying when attempting to copy log file contents.

The solution was simpler and somewhat counter intuitive.

In iterm2 there is an option under Preferences –> General –> Selection

Check “Copied text includes trailing newline”

Double click select entire word in terminal (iterm2) on MAC OSX

Posted on October 3, 2022 by dsg_admin

I have had issues when using Remote Desktop Manager Free (RDM) for MAC OSX.

Firstly ensure that you have iterm2 selected as the terminal

Next you want to be sure you are using the Legacy Engine set to NO under

Preferences > Types > Terminal:

I filed a bug with Devolutions and here is the reference link: https://forum.devolutions.net/topics/35957/doubleclick-select-in-terminal

Determine the Active Network Interface and IP address from Terminal on a MAC

Posted on September 28, 2022 by dsg_admin

On a MAC (OSX) Using the command line (Terminal) often you want a quick way to determine the Active Network Interfaces along with the IP address.

Here is a quick ‘alias’ you can make to get the IP(s)

# scutil --nwi|awk 'BEGIN {s=0} $0 ~ /^IPv4/ {s=1;next} s==1 && $0 ~ /flags/ {intf=$1;next} s==1 && $1 ~ /address/ {ip=$NF; print intf,ip} $1 ~ /REACH/{exit}'

Example Output

# scutil --nwi|awk 'BEGIN {s=0} $0 ~ /^IPv4/ {s=1;next} s==1 && $0 ~ /flags/ {intf=$1;next} s==1 && $1 ~ /address/ {ip=$NF; print intf,ip} $1 ~ /REACH/{exit}'
en9 192.168.1.88

Creating a small bash script in /usr/local/bin/ so you can reference it anytime.

#!/bin/bash
# scutil --nwi|awk 'BEGIN {s=0} $0 ~ /^IPv4/ {s=1;next} s==1 && $0 ~ /flags/ {intf=$1;next} s==1 && $1 ~ /address/ {ip=$NF; print intf,ip} $1 ~ /REACH/{exit}'

If you wish to only view the active interfaces on MAC OS you can do the following and create an alias for it

#ifconfig | pcregrep -M -o '^[^\t:]+(?=:([^\n]|\n\t)*status: active)'

Example Output

# ifconfig | pcregrep -M -o '^[^\t:]+(?=:([^\n]|\n\t)*status: active)'

Intel SP2600TP Board Boots at Bios Screen to error 26 in lower right corner

Posted on August 25, 2022 by dsg_admin

PROBLEM

It was seen recently on a T7000 whereby an Intel S2600TP system that boots and the only thing on the screen is the following with the number 26 in the lower right corner.

Text on the screen reads as:

Board Name S2600TP
Chipset initialization complete. No errors found.
26 (lower right hand corner).

CAUSE

I filed case 00556496 with Intel and the results were as follows:

POST code 26 indicates it may hang on to the Memory Reference Phrase (MRC) phase as MRC training is a failure. In this scenario, we recommend changing other DIMMs or boards.

SOLUTION

Replace the Memory, or since if Memory is not FRU, replace the controller.

ADDITIONAL INFORMATION

For additional information on other codes, see: S2600TP Intel Troubleshooting Guide
