 "Navigating in tmux after using GNU screen requires adjusting to one fundamental change: the default prefix shortcut is Ctrl+b instead of Ctrl+a. However, the core concept of navigating windows remains remarkably similar, while managing "panes" (splits) is significantly easier in tmux." <ref>https://medium.com/@yiskylee/gnu-screen-and-tmux-which-should-you-choose-de325d32fc2a</ref>

Pinentry

New page

echo -e 'SETTITLE YUBI\nSETDESC YUBI\nSETPROMPT YUBI\nSETERROR YUBI\nGETPIN\n' | /usr/bin/pinentry | grep '^D'

sample-pinentry.sh ::
<pre>
#!/bin/bash

# Ensure pinentry is installed
command -v pinentry >/dev/null 2>&1 || {
echo "ERROR: pinentry not found"
exit 1
}

# Talk to pinentry using its text protocol
response=$(
{
echo "SETTITLE Credential Prompt"
echo "SETPROMPT Passphrase:"
echo "SETDESC Please enter your passphrase."
echo "GETPIN"
} | pinentry
)

# Extract the entered PIN/password
pin=$(echo "$response" | awk '/^D / {print substr($0,3)}')

if [[ -n "$pin" ]]; then
echo "Passphrase was entered."
echo "Length: ${#pin}"
# Do something with $pin here
else
echo "No passphrase entered or dialog cancelled."
fi
</pre>

secure-sample-pinentry.sh ::

<pre>
#!/bin/bash

pin=$(
{
echo "SETTITLE Secure Prompt"
echo "SETPROMPT Password:"
echo "GETPIN"
} | pinentry | sed -n 's/^D //p'
)

if [[ -z "$pin" ]]; then
echo "Cancelled"
exit 1
fi

# Use the secret
echo "Received secret"

# Clear the variable when done
unset pin
</pre>

== Info ==

When the user enters a value, pinentry returns lines similar to:
<pre>
OK Pleased to meet you
D MySecretPassword
OK
</pre>

The line beginning with D contains the entered secret, which is why the script extracts it.

== gpg-agent version ==

Example 1: Ask for a passphrase via gpg-agent

<pre>
#!/bin/bash

# Establish a connection to gpg-agent
GPG_CONNECT=$(gpg-connect-agent /bye 2>/dev/null)

if [[ $? -ne 0 ]]; then
echo "gpg-agent is not running"
exit 1
fi

# Request a passphrase
response=$(
gpg-connect-agent <<EOF
GET_PASSPHRASE --data mycacheid X X "Enter your password"
/bye
EOF
)

password=$(echo "$response" | sed -n 's/^D //p')

if [[ -z "$password" ]]; then
echo "User cancelled"
exit 1
fi

echo "Password received"
unset password
</pre>

This caches the password, so if you call it again, it will have it stored.

--

Example 2: Trigger the user's configured pinentry

This example lets gpg-agent display the configured Pinentry GUI:

<pre>
#!/bin/bash

result=$(
gpg-connect-agent <<'EOF'
GET_PASSPHRASE myapp-login X X "Please enter your password"
/bye
EOF
)

secret=$(echo "$result" | sed -n 's/^D //p')

if [[ -n "$secret" ]]; then
echo "Success"
else
echo "Cancelled"
fi
</pre>

--

Example 3: Cache the secret

A nice feature of gpg-agent is passphrase caching:

<pre>
#!/bin/bash

CACHE_ID="my-company-tool"

secret=$(
gpg-connect-agent <<EOF |
GET_PASSPHRASE $CACHE_ID X X "Authentication Required"
/bye
EOF
sed -n 's/^D //p'
)

echo "Secret obtained"
</pre>

This one didn't seem to work for me?

--- Setup --

export GPG_TTY=$(tty)
gpg-connect-agent updatestartuptty /bye

Configure ~/.gnupg/gpg-agent.conf
pinentry-program /usr/bin/pinentry-tty
pinentry-program /usr/bin/pinentry-curses

--- manually test --

<pre>
gpg-connect-agent <<EOF
GET_PASSPHRASE mytest X X "Enter Password"
EOF
</pre>

== Direct Pin Entry Example ==

<pre>
#!/bin/bash

output=$(
{
echo "SETTITLE Login"
echo "SETPROMPT Password:"
echo "SETDESC Please enter your password."
echo "GETPIN"
} | pinentry
)

secret=$(sed -n 's/^D //p' <<< "$output")

if [[ -z "$secret" ]]; then
echo "Cancelled"
exit 1
fi

echo "Got password (${#secret} chars)"

All verified. Here are the exact commands.

## Chassis power (BMC / IPMI)

```bash
# Current draw — single number
ipmitool sensor get "PW Consumption"
# Sensor Reading : 342 (+/- 0) Watts

# Current draw + historical min/max/avg over the sampling window
ipmitool dcmi power reading
# Instantaneous power reading: 342 Watts
# Minimum during sampling period: 144 Watts
# Maximum during sampling period: 580 Watts
# Average power reading: 211 Watts

# Is a power cap configured?
ipmitool dcmi power get_limit # → "not returned (80)" = unsupported here

# All voltage/power rails at once
ipmitool sdr elist full | grep -iE "watt|power|current|amp|volt"
```

## Power supply health

```bash
# PSU status — this is what found the failed PSU
ipmitool sdr type "Power Supply"
# PS1 Status | C0h | ok | 10.1 | Presence detected, Failure detected, Power Supply AC lost
# PS2 Status | C1h | ok | 10.2 | Presence detected

# Detail on one PSU
ipmitool sensor get "PS1 Status"

# Historical power events
ipmitool sel list | grep -iE "power|supply"

# Full event log minus login noise
ipmitool sel list | grep -viE "session audit" | tail -25
```

## Drive power (NVMe — declared, not measured)

```bash
# Declared max power per power state
nvme id-ctrl /dev/nvme0 -H | grep -A2 "^ps "
# ps 0 : mp:25.00W idle_power:5.00W active_power:25.00W

# Which power state is currently active
nvme get-feature /dev/nvme0 -f 0x02 -H
# Power State (PS): 0
```

## Drive thermal / throttle proxies

Since watts aren't readable per-drive, these are the indicators that the drive hit its power limit:

```bash
# Live temps + throttle counters
nvme smart-log /dev/nvme0 | grep -iE "^temperature|Warning Temperature Time|Critical Composite|Temperature Sensor"

# Thresholds to compare against
nvme id-ctrl /dev/nvme0 | grep -iE "^wctemp|^cctemp" # 350K=77°C warn, 358K=85°C critical
nvme get-feature /dev/nvme0 -f 0x04 -H # over-temp threshold
```

Current reading, 11 min into the run:

```
temperature : 43 °C
Warning Temperature Time : 0
Critical Composite Temperature Time : 0
Temperature Sensor 3 : 68 °C
```

Both throttle counters still zero, so the drive is not power/thermal limited.

## The continuous sampler

The script combining all of the above is at `smartmon.sh`, writing fsync'd rows every 10 s to `smart_monitor.csv`. The two power fields in it are:

```bash
ipmitool dcmi power reading | awk '/Instantaneous/{print $4}'
nvme get-feature /dev/nvme0 -f 0x02 | grep -oE 'Current value:[0-9a-fx]+' | cut -d: -f2
```

Quick analysis of the collected data:

```bash
# Peak chassis watts observed
awk -F, 'NR>1 && $16+0>m {m=$16+0} END{print m" W"}' smart_monitor.csv

# Any row where a warning fired
awk -F, 'NR>1 && ($2!=0 || $8!=0 || $9!=0)' smart_monitor.csv
```

			== Decrypt Variable ==

			ansible-vault is not designed to encrypt and then decrypt strings, but to embed them in playbooks. If you want to decrypt a string you will need to format it correctly:
			* Crucial Formatting Rules: Remove any YAML indentation spaces from the front of each line and strip out the !vault \| tag if it is present. The block must start flush against the margin, beginning with $ANSIBLE_VAULT. <ref>https://docs.ansible.com/projects/ansible/latest/vault_guide/vault_encrypting_content.html</ref>
			* umm.. mytesting shows just delete the whole testvar: line and remove the indents

			==== Get Node Hardware Details ====

			CPU and RAM (Ki) and OS:
			kubectl get nodes -o jsonpath='{range .items[*]}{.metadata.name}{"\t"}CPUs: {.status.capacity.cpu}{"\t"}Mem: {.status.capacity.memory}{"\t"}OS: {.status.nodeInfo.osImage}{"\n"}{end}'

			If you need motherboard details, you will need root permissions to the "default" scope:
			kubectl debug node/<node-name> -it --image=busybox -- chroot /host cat /sys/class/dmi/id/board_name
			kubectl debug node/<node-name> -it --image=alpine -- chroot /host dmidecode -t baseboard
