= Module Overview =

An '''IRC operator''', commonly called an '''IRCOp''', is a trusted network staff member with elevated privileges for protecting and operating the IRC network.

IRC operator access may allow a person to:

* View additional network information.
* Receive operational server notices.
* Investigate abuse.
* Disconnect users.
* Apply network-level restrictions.
* Assist during floods and attacks.
* Coordinate incidents across servers.
* Override some normal channel restrictions.
* Perform other actions defined by their oper class.

These powers can affect many users and must be used with restraint, accuracy, authorization, and accountability.

<div style="background:#fdecec; border-left:4px solid #dc2626; padding:12px; margin:15px 0;">
'''Important:''' Completing this lesson does not grant IRC operator access. Candidates must not use operator commands on the production network unless separately authorized and assigned an approved oper account.
</div>

= Learning Objectives =

After completing this module, the candidate should be able to:

# Explain the purpose and limits of IRC operator access.
# Secure an operator account.
# Distinguish local and global network actions.
# Interpret common operational information.
# Investigate users without exposing private information.
# Explain kills and network-level restrictions.
# Select proportionate restriction scope and duration.
# Understand OperOverride and forced-mode risks.
# Recognize netsplits and server-link incidents.
# Assist safely during floods and attacks.
# Verify and document operator actions.
# Escalate high-risk commands and infrastructure issues.

= 1. IRC Operator Role =

IRC operators protect and support the IRC network.

Their responsibilities may include:

* Enforcing network-wide rules.
* Responding to multi-channel abuse.
* Investigating spam and ban evasion.
* Containing malicious clients or bots.
* Assisting during raids and floods.
* Monitoring authorized server notices.
* Coordinating with Services staff.
* Supporting channel staff in network-level cases.
* Documenting important actions.
* Escalating server and security incidents.

IRC operators do not own every channel and should not interfere with ordinary channel management without a valid network-level reason.

= 2. Operator Access Is Role-Based =

Different IRC operators may have different permissions.

An oper class may control:

* Which commands are available.
* Which server notices are visible.
* Whether actions are local or global.
* Which users or servers can be affected.
* Whether override powers are available.
* Which administrative resources can be accessed.

A staff title does not guarantee every IRC operator permission.

Staff must not attempt to bypass their oper-class restrictions.

= 3. Local and Global Actions =

== Local Action ==

A local action generally applies only to:

* The current IRC server.
* Users connected directly to that server.
* A server-specific operational condition.

== Global Action ==

A global action may apply across the entire IRC network.

Global actions present greater risk because they may affect:

* Users on every server.
* Multiple regions.
* Shared providers.
* Relays and bouncers.
* Legitimate users unrelated to the incident.

Before choosing a global action, ask whether a local or narrower restriction would solve the problem.

= 4. Operator Account Security =

An operator account is a privileged security credential.

Operators must:

* Use a strong, unique password.
* Never reuse a NickServ or personal password.
* Use TLS.
* Use a trusted device.
* Protect client configuration files.
* Avoid storing credentials in plaintext where possible.
* Avoid public or untrusted computers.
* Keep the operating system and IRC client updated.
* Secure bouncers used for operator access.
* Report suspected compromise immediately.
* Follow any approved certificate or authentication requirements.
* Oper only when required by current procedure.

Operators must never:

* Share an oper account.
* Give credentials to another staff member.
* paste an operator password into a channel.
* Send credentials through an unofficial bot.
* Leave an authorized client accessible to others.
* Use production access for demonstrations.
* Save passwords in public scripts or repositories.

= 5. Becoming an IRC Operator =

Traditional IRC operator authentication may use:

<pre>
/OPER opername password
</pre>

DarkWorld IRC may use additional controls, such as:

* Restricted source hosts.
* TLS requirements.
* Client certificates.
* Certificate fingerprints.
* Security groups.
* Password hashing.
* Separate oper classes.
* Two-stage authorization.
* Approved bouncer or server access.

Candidates must follow the current DarkWorld procedure.

Do not demonstrate `/OPER` in public, record a real password in training material, or use another person’s oper account.

= 6. Failed Operator Login =

An operator login may fail because:

* Oper name is incorrect.
* Password is incorrect.
* Source host is not authorized.
* TLS is not enabled.
* Required certificate is missing.
* Certificate fingerprint does not match.
* Oper block or class changed.
* Account is suspended.
* The user is connected to an incorrect server.
* Server configuration has not been reloaded correctly.

After an unexpected failure:

# Do not repeatedly guess passwords.
# Confirm TLS and the approved connection method.
# Record the exact error.
# Check whether the oper account was recently changed.
# Notify authorized administration.
# Treat unexplained repeated failures as a possible security event.

= 7. Server Notices =

IRC operators may receive additional server notices relating to:

* User connections and disconnections.
* Failed authentication.
* Kills.
* Network bans.
* Flood activity.
* Server links and disconnections.
* Services activity.
* Operator logins.
* Security events.
* Routing issues.
* Configuration warnings.

UnrealIRCd may use server-notice masks or related configuration to control which notices an operator receives.

Staff should subscribe only to notices appropriate to their role.

Too many notices can hide important events. Too few may prevent early detection.

= 8. Operational Information Commands =

Depending on permissions, useful commands may include:

<pre>
/WHOIS nickname
/WHOIS nickname nickname
/WHO #channel
/USERHOST nickname
/LINKS
/MAP
/LUSERS
/VERSION
/TIME
/ADMIN
/STATS
/TRACE
</pre>

Availability and output depend on the current UnrealIRCd version, configuration, and oper permissions.

Candidates should use:

<pre>
/HELPOP command
</pre>

or the current official server documentation before using an unfamiliar operator command.

= 9. WHOIS for Operators =

An operator WHOIS response may provide additional information.

It may include:

* Nickname.
* Ident.
* Displayed host.
* Registered account.
* Connected server.
* Channels.
* User modes.
* Secure connection status.
* Idle time.
* Operator status.
* Security-related information available to the oper class.
* Original connection information.

Staff may use this information only for an authorized operational purpose.

Hidden connection information must not be:

* Posted publicly.
* Shared with channel operators unnecessarily.
* Used to embarrass a user.
* Accessed out of curiosity.
* Copied into unrelated cases.
* Used for personal retaliation.

= 10. Investigating a User =

Before using elevated information, identify:

* The reported conduct.
* The applicable policy.
* The relevant time.
* The channel or recipients.
* Evidence already available.
* Whether the incident is ongoing.
* Whether the requested information is necessary.
* Whether you have permission to access it.

An investigation should remain limited to the incident.

Do not expand a routine spam report into a broad search of unrelated user activity without authorization.

= 11. Identity Correlation =

Operators may observe connections that share:

* IP addresses.
* Hostnames.
* Idents.
* Accounts.
* Certificates.
* Bouncers.
* VPN exits.
* Proxies.
* Gateways.
* Behavioral patterns.

Shared information does not automatically prove common control.

Examples:

* A household may share one address.
* A university or company may use shared NAT.
* A VPN exit may serve many customers.
* A ZNC provider may host many users.
* A web gateway may show similar connection information.
* IPv6 users may rotate addresses within an assigned range.

Identity conclusions should use multiple relevant indicators and be stated carefully.

= 12. KILL =

A kill disconnects a user from IRC.

General syntax:

<pre>
/KILL nickname reason
</pre>

Example used only for an authorized training environment:

<pre>
/KILL TestUser Active multi-channel flooding
</pre>

A kill:

* Ends the current IRC connection.
* Does not necessarily prevent reconnection.
* Does not automatically ban an account or address.
* May be appropriate for immediate containment.
* Must include a professional reason.
* Should be recorded when significant.

== Appropriate Uses May Include ==

* Active multi-channel flooding.
* Credential phishing.
* Malicious bot activity.
* Severe ongoing network abuse.
* Immediate containment during an investigation.

== Inappropriate Uses Include ==

* Personal disagreement.
* Minor channel-rule violations.
* User criticism of staff.
* Demonstrations or jokes.
* Avoiding ordinary channel moderation.
* Disconnecting someone without checking the target.

= 13. Network-Level Restrictions =

UnrealIRCd may provide several restriction types.

Exact syntax, matching behavior, storage, and scope must be confirmed with the current server help and DarkWorld procedures.

Possible types include:

{| class="wikitable" style="width:100%;"
! Restriction
! General purpose
! Main concern
|-
| Local connection ban
| Restricts matching users on one server
| May not protect other servers
|-
| Global connection ban
| Restricts matching users network-wide
| May affect many legitimate users
|-
| IP-based restriction
| Restricts a specific address or range
| Shared or dynamic addresses
|-
| Z-line-style restriction
| Blocks matching IP connections at an early stage
| Very broad and difficult for affected users
|-
| Shun-style restriction
| Silently limits many commands from a user
| User may not understand what is happening
|-
| Temporary restriction
| Expires automatically after a duration
| Duration and matching must still be accurate
|-
| Permanent restriction
| Remains until removed
| Requires strong justification and review
|}

Common UnrealIRCd command names may include:

<pre>
KLINE
GLINE
ZLINE
GZLINE
SHUN
TEMPSHUN
</pre>

This list is informational. Candidates must not execute these commands on production without explicit authorization.

= 14. Restriction Selection =

Before applying a network restriction, determine:

# Is a network-level restriction required?
# Is the incident still active?
# Which identity or connection property should match?
# Is the target shared?
# Would a local restriction be sufficient?
# Would an account-based action be more accurate?
# What duration is proportionate?
# How many legitimate users may be affected?
# Is there a documented reason?
# Who authorized the action?
# How will the restriction be reviewed and removed?

= 15. Restriction Scope =

Possible scope choices include:

* One current connection.
* One account.
* One visible user mask.
* One IP address.
* One hostname.
* One IPv4 range.
* One IPv6 prefix.
* One provider or autonomous network.
* One server.
* The entire IRC network.

As scope grows, risk grows.

A provider-wide restriction should not be selected merely because it is easier than identifying the actual source.

= 16. IPv4 and IPv6 Considerations =

== IPv4 ==

Multiple users may share one public IPv4 address because of:

* Home routers.
* Carrier-grade NAT.
* Business networks.
* VPNs.
* Bouncers.
* Web gateways.

== IPv6 ==

IPv6 users may have:

* A stable individual address.
* Temporary privacy addresses.
* Multiple addresses.
* An assigned prefix.
* Rotating interface identifiers.

An IPv6 restriction that is too narrow may be easily avoided. One that is too broad may block many unrelated systems.

Prefix-based decisions should be made only by trained and authorized staff using accurate network information.

= 17. Restriction Duration =

Possible durations might include:

* A few minutes during active flooding.
* Several hours.
* One day.
* Several days.
* A longer reviewed period.
* Indefinite, only where properly authorized.

Duration should reflect:

* Severity.
* Repetition.
* Likelihood of recurrence.
* Previous relevant history.
* Shared-host impact.
* Whether the source was compromised.
* Whether the actor cooperated.
* Whether the incident remains under investigation.

Temporary restrictions are often safer during an evolving incident because they force a later decision instead of remaining forgotten.

= 18. Restriction Reasons =

A network-restriction reason should be:

* Specific.
* Factual.
* Professional.
* Connected to policy.
* Understandable during review.
* Free from unnecessary sensitive information.

Good examples:

<pre>
Active multi-channel flooding
Credential phishing through NickServ impersonation
Repeated network advertising after warning
Ban evasion during active harassment incident
Malicious relay activity pending compliance review
</pre>

Poor examples:

<pre>
Bad user
Go away
Annoying
Staff decision
You know why
</pre>

Where supported by procedure, include an internal case reference.

= 19. Verifying an Operator Action =

After sending an elevated command:

# Read the server response.
# Confirm the intended target.
# Confirm the scope.
# Confirm the duration.
# Check the relevant restriction list or logs.
# Verify that the incident stopped.
# Check for unintended impact.
# Record the action.
# Set a review time.

Never assume success merely because the command was sent.

= 20. Removing Restrictions =

Before removing a restriction:

* Confirm the exact entry.
* Confirm the original reason.
* Check whether the incident is resolved.
* Check whether another active case depends on it.
* Confirm your authority.
* Record who removed it and why.
* Monitor for recurrence.

Do not remove another operator’s restriction merely because the affected user asks privately.

Use the appeal and review procedure.

= 21. Shuns and Silent Restrictions =

A shun-style action may cause many user commands or messages to be ignored while the connection remains active.

Possible benefits:

* Limits an active abusive client.
* Reduces immediate disruption.
* Gives staff time to investigate.
* May prevent an automated client from adapting immediately.

Risks:

* The user may not know why commands fail.
* Legitimate support requests may be blocked.
* The restriction may be forgotten.
* It may complicate evidence.
* It can be abused as an invisible punishment.

Shuns should be authorized, documented, reviewed, and removed removed when no longer needed.

= 22. OperOverride =

OperOverride may allow an IRC operator to bypass normal channel restrictions.

Depending on configuration, it may permit actions such as:

* Joining a restricted channel.
* Acting despite channel access limits.
* Changing modes without normal channel privileges.
* Performing emergency intervention.

OperOverride must be limited to valid network duties.

Appropriate examples may include:

* Stopping an active serious policy violation.
* Responding to a channel takeover.
* Entering a channel during an urgent network incident.
* Protecting users when normal channel management is unavailable.

Inappropriate examples include:

* Joining a private channel out of curiosity.
* Overriding a channel founder during a personal dispute.
* Obtaining operator status for entertainment.
* Monitoring private conversations without authorization.
* Avoiding the normal appeal or Services process.

= 23. SAMODE and Forced Modes =

Forced-mode commands may allow authorized IRC operators to change:

* Channel modes.
* User status.
* User modes.
* Other protected state.

These commands can override normal channel authority and must be treated as high risk.

Before using a forced mode:

# Confirm the target.
# Confirm the current state.
# Identify the network-level reason.
# Obtain required authorization.
# Use the smallest effective change.
# Record the previous state.
# Apply the change.
# Verify the result.
# Restore or review it afterward.

A forced mode should never be used merely because it is faster than contacting the channel founder or using ChanServ correctly.

= 24. Server Links and Netsplits =

DarkWorld IRC uses multiple linked servers.

A server-link problem may cause:

* Many users to quit simultaneously.
* Channels to temporarily split.
* Duplicate state on separate sides.
* Services access to disappear temporarily.
* Servers to reconnect repeatedly.
* Large groups of users to return.
* Mode synchronization activity.

Operators should distinguish:

* A normal user disconnection.
* A server ping timeout.
* A netsplit.
* A deliberate server disconnect.
* A routing or TLS link failure.
* A server under attack.

== Operator Response ==

# Identify the affected server.
# Record the time.
# Review authorized server notices.
# Notify network operations.
# Avoid unnecessary global restrictions.
# Avoid promising an unsupported cause.
# Allow synchronization after reconnection.
# Check whether channels and Services recovered.
# Document persistent or repeated failures.

= 25. Server Administration Commands =

UnrealIRCd may provide commands capable of:

* Connecting a server.
* Disconnecting a server.
* Rehashing configuration.
* Restarting a server.
* Shutting down a server.
* Changing routing.
* Broadcasting network notices.

Examples may include command names such as:

<pre>
CONNECT
SQUIT
REHASH
RESTART
DIE
</pre>

<div style="background:#fdecec; border-left:4px solid #dc2626; padding:12px; margin:15px 0;">
'''Critical restriction:''' These are server-administration commands, not general IRC operator tools. They must not be used by trainees or unauthorized operators.
</div>

Incorrect use may:

* Disconnect hundreds of users.
* Split the network.
* Interrupt Services.
* Prevent reconnection.
* Apply broken configuration.
* Create a security incident.

Detailed use belongs in the separate IRCd Administration Program.

= 26. Flood and Attack Response =

Network attacks may include:

* Connection floods.
* Registration floods.
* Nickname floods.
* Join floods.
* Distributed message floods.
* CTCP floods.
* Reconnect loops.
* Malicious bot networks.
* Targeted server attacks.

An IRC operator should:

# Confirm the observed behavior.
# Determine affected servers and channels.
# Notify the incident lead.
# Apply only approved protective measures.
# Avoid broad reactive bans without impact review.
# Preserve server notices and timestamps.
# Coordinate with IRCd administrators.
# Monitor whether the attack changes method.
# Record temporary actions.
# Review and remove emergency restrictions later.

IRC operators should not independently change firewalls, IRCd configuration, DNS, or provider-level protection unless separately authorized.

= 27. Network Notices =

Authorized operators may send notices to:

* One user.
* One server’s users.
* All network users.
* Specific staff groups.

Network-wide notices should be reserved for information that users need.

A good notice is:

* Accurate.
* Short.
* Actionable.
* Professionally written.
* Approved where required.

Example:

<pre>
DarkWorld IRC is investigating a temporary connectivity issue affecting some users. Please avoid repeated reconnect attempts and monitor #Help for updates.
</pre>

Avoid:

* Personal announcements.
* Arguments.
* Unverified claims.
* Public accusations.
* Excessive repeated notices.
* Confidential incident details.
* Advertising unrelated to network operations.

= 28. Services and IRC Operator Boundaries =

IRC operator access and Services administration are separate.

An IRC operator may be able to:

* Disconnect an abusive user.
* Apply an authorized connection restriction.
* Respond to a network attack.
* Review operational information.

They may not automatically be authorized to:

* Change a NickServ account owner.
* Change a ChanServ founder.
* Drop registered accounts or channels.
* Suspend Services records.
* Modify the Anope database.
* Assign vhosts.
* Use all OperServ commands.

Services actions require the appropriate Services role.

= 29. Other DarkWorld Project Boundaries =

IRC operator access does not authorize the operator to:

* Access DWShells servers.
* Suspend shell accounts.
* Modify DWBouncers users.
* Access project databases.
* Change websites.
* Manage unrelated project applications.
* Use server credentials belonging to another team.

If IRC abuse originates from another DarkWorld project:

# Protect the IRC network.
# Preserve relevant evidence.
# Notify the relevant project team.
# Separate IRC action from project action.
# Coordinate through authorized staff.
# Record cross-project decisions.

= 30. Operator Logs and Accountability =

Important operator actions should be logged.

A record may include:

<pre>
Date and time:
Operator:
Command or action:
Target:
Scope:
Duration:
Reason:
Policy or incident reference:
Evidence location:
Authorized by:
Result:
Unexpected impact:
Review date:
Removal or expiry:
</pre>

Operator logs must not be altered to conceal mistakes.

Where sensitive information is required, access to the record should be restricted appropriately.

= 31. Mistakes and Emergency Correction =

If an operator affects the wrong user or scope:

# Stop continuing harm.
# Correct or remove the action.
# Verify recovery.
# Notify the incident lead or senior staff.
# Inform affected users appropriately.
# Preserve the original command record.
# Record the correction.
# Review why the mistake occurred.
# Improve the procedure.

Operators should not hide mistakes out of fear of criticism. Concealment creates a greater trust and security problem.

= 32. Operator Conflicts of Interest =

An operator should not be the sole decision-maker when:

* They are personally involved.
* A friend or project associate is involved.
* They previously argued with the user.
* Their own action is being appealed.
* They may benefit from the restriction.
* They have publicly prejudged the case.

During immediate danger, they may take the minimum protective action and then transfer the matter to a neutral reviewer.

= 33. Operator Handover =

When leaving an active incident, provide:

<pre>
Incident reference:
Current incident lead:
Affected users/channels/servers:
Confirmed facts:
Active network restrictions:
Restriction scope:
Restriction duration:
Reason:
Evidence location:
Server or Services state:
Teams notified:
Pending actions:
Next review time:
</pre>

The receiving operator should confirm acceptance.

= 34. Practical Laboratory Rules =

Operator exercises must use:

* A dedicated test server, or
* An approved isolated training environment, or
* A trainer-controlled simulation.

Production operator commands must not be used for practice.

The laboratory should use:

* Test accounts.
* Test channels.
* Non-production oper credentials.
