This script should be run on the master KDC/admin server to initialize
a Kerberos realm.  It will ask you to type in a master key password.
This password will be used to generate a key that is stored in
/etc/krb5kdc/stash.  You should try to remember this password, but it
is much more important that it be a strong password than that it be
remembered.  However, if you lose the password and /etc/krb5kdc/stash,
you cannot decrypt your Kerberos database.
Loading random data
Initializing database '/var/lib/krb5kdc/principal' for realm 'EXAMPLE.ORG',
master key name 'K/M@EXAMPLE.ORG'
You will be prompted for the database Master Password.
It is important that you NOT FORGET this password.
Enter KDC database master key:
Re-enter KDC database master key to verify:
Now that your realm is set up you may wish to create an administrative
principal using the addprinc subcommand of the kadmin.local program.
Then, this principal can be added to /etc/krb5kdc/kadm5.acl so that
you can use the kadmin program on other computers.  Kerberos admin
principals usually belong to a single user and end in /admin.  For
example, if jruser is a Kerberos administrator, then in addition to
the normal jruser principal, a jruser/admin principal should be
created.
Don't forget to set up DNS information so your clients can find your
KDC and admin servers.  Doing so is documented in the administration
guide.

نام	مفهوم
binary	یک رشته دلخواه از بایت‌ها که به‌صورت مجموعه‌ای از ارقام هگزادسیمال مشخص می‌شود.
boolean	یک مقدار بولی با مقادیر مجاز true یا false.
empty	بدون مقدار؛ داده‌ها در زیرگزینه‌ها (sub-options) حمل می‌شوند.
fqdn	نام دامنه کاملاً واجد شرایط (مانند www.example.com).
ipv4-address	آدرس IPv4 در نماد نقطه‌ـ‌ده‌دهی معمول (مانند 192.0.2.1).
ipv6-address	آدرس IPv6 در نماد دونقطه‌ای معمول (مانند 2001:db8::1).
ipv6-prefix	پیشوند IPv6 و طول پیشوند مشخص‌شده با نمادگذاری CIDR، مانند 2001:db8:1::/64. این نوع داده برای نمایش یک فیلد ۸ بیتی حامل طول پیشوند و مقدار پیشوند با طول متغیر استفاده می‌شود.
psid	‏PSID و طول PSID که با ممیز از یکدیگر جدا شده‌اند، مثلاً 3/4 مشخص‌کننده PSID=3 و طول PSID برابر با ۴ است. در قالب انتقال روی شبکه (wire format)، با یک فیلد ۸ بیتی حامل طول PSID (در این حالت برابر با ۴) و فیلد ۱۶ بیتی مقدار PSID (در این حالت برابر با "0011000000000000b" در نماد دودویی) نمایش داده می‌شود. مقادیر مجاز برای طول PSID بین ۰ تا ۱۶ است. برای جزئیات مربوط به قالب نمایش PSID در شبکه به RFC 7597 https://datatracker.ietf.org/doc/html/rfc7597 مراجعه کنید.
record	داده‌های ساختاریافته که می‌توانند از هر نوعی (به‌جز "record" و "empty") تشکیل شوند. نشانگر (flag) آرایه فقط بر روی فیلد آخر اعمال می‌شود.
string	هر نوع متن. لطفاً توجه داشته باشید که Kea هنگام باز کردن بسته‌های دریافتی، کاراکترهای نال (null) پایانی را از انتهای گزینه‌های "string" بدون هشدار حذف می‌کند. این رفتار مطابق با بخش ۲ از RFC 2132 https://datatracker.ietf.org/doc/html/rfc2132#section-2 است.
tuple	یک فیلد طول که به‌صورت عدد صحیح بدون علامت ۸ یا ۱۶ بیتی کدگذاری شده و پس از آن رشته‌ای با همین طول می‌آید. معمولاً برای DHCPv4 طول ۸ بیتی و برای DHCPv6 طول ۱۶ بیتی است. با این حال، استثناهایی برای این قاعده وجود دارد؛ برای نمونه در گزینه DHCPv4 SZTP Redirect Option، مقدار bootstrap-server-list به‌صورت فهرستی از تاپل‌ها (tuples) کدگذاری می‌شود که در آن URI-length در هر تاپل یک عدد صحیح بدون علامت ۱۶ بیتی است.
uint8	یک عدد صحیح بدون علامت ۸ بیتی با مقادیر مجاز ۰ تا ۲۵۵.
uint16	یک عدد صحیح بدون علامت ۱۶ بیتی با مقادیر مجاز ۰ تا ۶۵۵۳۵.
uint32	یک عدد صحیح بدون علامت ۳۲ بیتی با مقادیر مجاز ۰ تا ۴۲۹۴۹۶۷۲۹۵.
int8	یک عدد صحیح علامت‌دار ۸ بیتی با مقادیر مجاز -128 تا 127.
int16	یک عدد صحیح علامت‌دار ۱۶ بیتی با مقادیر مجاز -32768 تا 32767.
int32	یک عدد صحیح علامت‌دار ۳۲ بیتی با مقادیر مجاز -2147483648 تا 2147483647.

نام	کد	توضیحات
circuit-id	1	هنگامی استفاده می‌شود که host-reservation-identifiers روی circuit-id تنظیم شده باشد.
remote-id	2	می‌تواند همراه با flex-id برای شناسایی میزبان‌ها استفاده شود.
link-selection	5	در صورت وجود، برای انتخاب زیرشبکه مناسب استفاده می‌شود.
subscriber-id	6	می‌تواند همراه با flex-id برای شناسایی میزبان‌ها استفاده شود.
server-id-override	11	در صورت ارسال توسط رله، Kea آن را به عنوان server-id می‌پذیرد.
relay-id	12	رله را شناسایی می‌کند
relay-port	19	در صورت ارسال توسط رله، Kea پاسخ‌های خود را به این درگاه ارسال می‌کند.

مورد پیکربندی Kea	مجاز	توضیح
زیرشبکه‌های هم‌پوشان	بله	مدیر سیستم باید به چگونگی تطبیق کلاینت‌ها با این زیرشبکه‌ها توجه داشته باشد.
استخرهای آدرس هم‌پوشان در یک زیرشبکه	خیر	خطای راه‌اندازی: DHCP6_PARSER_FAIL
استخرهای آدرس هم‌پوشان در زیرشبکه‌های مختلف	بله	مشخص کردن یک استخر آدرس یکسان در زیرشبکه‌های مختلف می‌تواند به عنوان معادل استخر آدرس سراسری (global address pool) استفاده شود. در این حالت، سرور می‌تواند فارغ از زیرشبکه کلاینت، آدرس‌ها را از همان محدوده تخصیص دهد. اگر آدرسی از چنین استخری به کلاینتی در یک زیرشبکه اختصاص یابد، در صورت انتقال کلاینت به زیرشبکه‌ای دیگر، همان آدرس برای این کلاینت تمدید خواهد شد. به کلاینت دیگری در یک زیرشبکه متفاوت، آدرسی که پیش‌تر به این کلاینت در هر یک از زیرشبکه‌ها اختصاص یافته است، داده نخواهد شد.
استخرهای آدرسی که خارج از زیرشبکه تعریف‌شده خود هستند	خیر	خطای راه‌اندازی: DHCP6_PARSER_FAIL
استخرهای واگذاری پیشوند هم‌پوشان در یک زیرشبکه	خیر	خطای راه‌اندازی: DHCP6_PARSER_FAIL
استخرهای واگذاری پیشوند هم‌پوشان در زیرشبکه‌های مختلف	بله	مشخص کردن یک استخر واگذاری پیشوند یکسان در زیرشبکه‌های مختلف می‌تواند به عنوان معادل استخر سراسری به کار رود. در این حالت، سرور می‌تواند صرف‌نظر از زیرشبکه کلاینت، همان پیشوندها را واگذار کند. اگر پیشوندی از چنین استخری به کلاینتی در یک زیرشبکه واگذار شود، در صورت جابجایی کلاینت به زیرشبکه‌ای دیگر، همان پیشوند برای این کلاینت تمدید خواهد شد. به کلاینت دیگری در یک زیرشبکه متفاوت، پیشوندی که پیش‌تر به این کلاینت در هر یک از زیرشبکه‌ها واگذار شده است، داده نخواهد شد.
استخرهای واگذاری پیشوندی که با پیشوند زیرشبکه مطابقت ندارند	بله	در بسیاری از پیاده‌سازی‌ها پیکربندی استخرهای واگذاری پیشوند به‌صورتی که با پیشوند زیرشبکه مطابقت نداشته باشند رایج است؛ مانند یک استخر پیشوند 3000::/96 درون زیرشبکه 2001:db8:1::/64. چنین مواردی توسط سرور Kea DHCPv6 پشتیبانی می‌شوند.

نام	دسترسی	توضیحات
BOOTP	متن‌باز Kea	این کتابخانهٔ هوک، پشتیبانی از BOOTP را مطابق با تعریف RFC 1497 اضافه می‌کند. این کتابخانه درخواست‌های دریافت‌شدهٔ BOOTP را شناسایی می‌کند: این درخواست‌ها به بسته‌های DHCPREQUEST ترجمه می‌شوند، در کلاس کلاینت BOOTP قرار می‌گیرند و اجاره‌هایی با طول عمر نامحدود دریافت می‌کنند.
Class Commands	متن‌باز Kea	این کتابخانهٔ هوک امکان افزودن، به‌روزرسانی، حذف و واکشی کلاس‌های کلاینتِ پیکربندی‌شدهٔ DHCP را بدون نیاز به راه‌اندازی مجدد کارساز DHCP فراهم می‌کند.
Configuration Backend Commands	مشتریان پشتیبانی ISC	این کتابخانهٔ هوک مجموعه‌ای از دستورها را برای مدیریت اطلاعات پیکربندی Kea در یک پایگاه داده پیاده‌سازی می‌کند. این کتابخانه فقط در کنار یکی از پیاده‌سازی‌های پشتیبانی‌شدهٔ Configuration Backend قابل استفاده است.
DDNS Tuning	متن‌باز Kea	این کتابخانهٔ هوک رفتارهای سفارشی مربوط به به‌روزرسانی‌های Dynamic DNS را بر پایهٔ هر کلاینت اضافه می‌کند. ویژگی اصلی آن امکان محاسبهٔ نام میزبان مورداستفاده برای DNS با استفاده از یک عبارت است.
Flexible Identifier	متن‌باز Kea	نرم‌افزار Kea روشی را برای مدیریت رزروهای میزبان فراهم می‌کند که شامل آدرس‌ها، پیشوندها، گزینه‌ها، کلاس‌های کلاینت و سایر ویژگی‌ها است. رزرو می‌تواند بر اساس آدرس سخت‌افزاری، DUID، circuit-id یا client-id در DHCPv4 و بر اساس آدرس سخت‌افزاری یا DUID در DHCPv6 انجام شود. با این حال، گاهی سناریوهایی رخ می‌دهد که در آن‌ها رزرو پیچیده‌تر است، مانند استفاده از گزینه‌هایی غیر از موارد یادشده، استفاده از بخش‌هایی از گزینه‌هایی خاص، یا شاید استفاده از ترکیبی از چندین گزینه و فیلد برای شناسایی یکتای یک کلاینت. این سناریوها توسط برنامهٔ هوک Flexible Identifier پوشش داده می‌شوند. این برنامه امکان تعریف یک عبارت، مشابه عبارت مورد استفاده در کلاس‌بندی کلاینت، مانند substring(relay6[0].option[37],0,6) را می‌دهد. هر بستهٔ ورودی بر اساس آن عبارت ارزیابی شده و سپس مقدار آن در پایگاه دادهٔ رزروها جستجو می‌شود.
Flexible Option	متن‌باز Kea	این کتابخانه هوک‌هایی را ارائه می‌دهد که مقادیر گزینه را به‌جای مقادیر ایستای پیکربندی‌شده محاسبه می‌کنند. یک عبارت بر روی بستهٔ پرس‌وجو ارزیابی می‌شود. عملیات‌های تعریف‌شدهٔ add، supersede و remove با استفاده از نتیجهٔ ارزیابی، پیش از ارسال روی بستهٔ پاسخ اعمال می‌شوند.
Forensic Logging	متن‌باز Kea	این کتابخانه هوک‌هایی را فراهم می‌آورد که گزارشی تفصیلی از تخصیص‌ها و تمدیدهای اجاره را در مجموعه‌ای از فایل‌های لاگ ثبت می‌کنند. در بسیاری از حوزه‌های قضایی، شرکت‌ها – به‌ویژه ISPها – موظف‌اند اطلاعات مربوط به آدرس‌هایی را که به کلاینت‌های DHCP اجاره داده‌اند ثبت کنند. این کتابخانه برای کمک به این الزام طراحی شده است. اگر اطلاعاتی که ثبت می‌کند کافی باشد، می‌توان مستقیماً از آن استفاده کرد. اگر حوزه‌ای قضایی نیازمند ذخیرهٔ مجموعهٔ متفاوتی از اطلاعات باشد، می‌توان از آن به عنوان الگو یا مثالی برای ایجاد هوک‌های لاگ‌گیری سفارشی استفاده نمود. در Kea 1.9.8، پارامترهای بیشتری اضافه شد تا انعطاف‌پذیری بیشتری در رابطه با این که چه اطلاعاتی باید ثبت شوند به کاربران داده شود.
GSS-TSIG	متن‌باز Kea	این کتابخانهٔ هوک پشتیبانی از استفاده از GSS-TSIG برای امضای به‌روزرسانی‌های DNS را به کارساز Kea D2 (kea-dhcp-ddns) اضافه می‌کند.
High Availability	متن‌باز Kea	خطر از دسترس خارج شدن سرویس DHCP را می‌توان با برپایی یک جفت کارساز DHCP در یک شبکه به حداقل رساند. دو حالت عملیاتی پشتیبانی می‌شود. حالت اول موازنهٔ بار نام دارد و گاهی از آن با عنوان "active-active" یاد می‌شود. هر کارساز می‌تواند گروه‌های منتخبی از کلاینت‌ها را در این شبکه مدیریت کند، یا در صورتی که تشخیص دهد همتایش از دسترس خارج شده، تمام کلاینت‌ها را مدیریت نماید. همچنین می‌توان یک کارساز را برای پاسخگویی به همهٔ کلاینت‌های DHCP تعیین کرد و کارساز دیگر را در حالت آماده‌باش قرار داد. این حالت "hot standby" نامیده می‌شود و گاهی به آن "active-passive" می‌گویند. این کارساز تنها زمانی عملکرد DHCP خود را فعال می‌کند که تشخیص دهد همتایش در دسترس نیست. چنین همکاری‌ای میان کارسازهای DHCP مستلزم آن است که این کارسازها پیوسته با یکدیگر در ارتباط باشند تا به‌روزرسانی‌های مربوط به اجاره‌های اختصاص‌یافته را ارسال کنند و به صورت دوره‌ای عملیاتی بودن همتای خود را بیازمایند. این کتابخانهٔ هوک همچنین امکان ارسال به‌روزرسانی‌های اجاره را به کارسازهای پشتیبان خارجی فراهم می‌کند که داشتن یک جایگزین کاملاً به‌روز را بسیار ساده‌تر می‌سازد.
Host Cache	متن‌باز Kea	پاسخ‌دهی برخی از Backendهای پایگاه داده، مانند RADIUS، ممکن است زمان زیادی ببرد. از آنجا که Kea به‌طور کلی همگام است، کارایی Backend مستقیماً بر کارایی DHCP اثر می‌گذارد. برای به حداقل رساندن افت کارایی، این کتابخانه روشی را برای کَش کردن پاسخ‌های سایر میزبان‌ها فراهم می‌کند. این شامل کَش منفی نیز می‌شود، یعنی توانایی به‌خاطرسپاری اینکه هیچ اطلاعات کلاینتی در پایگاه داده وجود ندارد.
Host Commands	متن‌باز Kea	کارساز Kea روشی برای ذخیرهٔ رزروهای میزبان در یک پایگاه داده فراهم می‌کند. در بسیاری از استقرارهای بزرگ‌تر، مدیریت این اطلاعات در زمان اجرای کارساز سودمند است. این کتابخانه دستورهای مدیریتی را برای افزودن، پرس‌وجو و حذف رزروهای میزبان به شکلی امن و بدون راه‌اندازی دوبارهٔ کارساز ارائه می‌دهد. به‌ویژه، پارامترها را اعتبارسنجی می‌کند، بنابراین تلاشی برای درج داده‌های نادرست، مانند افزودن میزبانی با شناسهٔ متداخل در همان زیرشبکه، رد خواهد شد. این دستورها از طریق کانال فرمان (JSON از طریق سوکت‌های UNIX یا HTTP/HTTPS) ارائه می‌شوند،
Lease Commands	متن‌باز Kea	این کتابخانهٔ هوک مجموعه‌ای از دستورها را برای مدیریت اجاره‌ها ارائه می‌دهد. Kea می‌تواند اطلاعات اجاره را در Backendهای مختلفی ذخیره کند: memfile، MySQL و PostgreSQL. این کتابخانه رابطی یکپارچه برای دستکاری اجاره‌ها به روشی هماهنگ و امن فراهم می‌کند. به‌ویژه، دستکاری اجاره‌های memfile در زمان اجرای Kea، بررسی درستی تغییرات، بررسی وجود اجاره، و حذف تمام اجاره‌های متعلق به یک زیرشبکهٔ خاص را امکان‌پذیر می‌کند. همچنین می‌تواند خطاهای پنهان را شناسایی کند، مانند افزودن اجاره‌ای با subnet-id که در پیکربندی وجود ندارد، یا پیکربندی یک اجاره برای استفاده از آدرسی خارج از زیرشبکه‌ای که باید به آن تعلق داشته باشد. این کتابخانه مدیریت آسان بسترهای کاربری (user contexts) مرتبط با اجاره‌ها را ممکن می‌سازد.
Leasequery	متن‌باز Kea	این کتابخانه پشتیبانی از DHCPv4 Leasequery (RFC 4388)، DHCPv4 Bulk Leasequery (RFC6926)، DHCPv6 Leasequery (RFC 5007) و DHCPv6 Bulk Leasequery (RFC5460) را اضافه می‌کند.
Limits	متن‌باز Kea	با این کتابخانهٔ هوک، کارسازهای kea-dhcp4 <#std-iscman-kea-dhcp4> و kea-dhcp6 <#std-iscman-kea-dhcp6> می‌توانند نرخی را که بسته‌ها بر اساس آن پاسخ دریافت می‌کنند محدود نمایند. این محدودیت می‌تواند بر پایهٔ هر کلاس کلاینت یا هر زیرشبکه اعمال شود.
MySQL Support Library	متن‌باز Kea	این کتابخانهٔ هوک، پشتیبانی از استفاده از پایگاه(های) دادهٔ MySQL را برای Backendهای Lease، Host و Configuration در Kea ارائه می‌دهد.
PerfMon	متن‌باز Kea	با این کتابخانهٔ هوک، کارسازهای kea-dhcp4 <#std-iscman-kea-dhcp4> و kea-dhcp6 <#std-iscman-kea-dhcp6> می‌توانند داده‌های مربوط به کارایی را رصد و گزارش کنند.
Ping Check	متن‌باز Kea	با این کتابخانهٔ هوک، کارساز kea-dhcp4 <#std-iscman-kea-dhcp4> می‌تواند پیش از پیشنهاد آدرس‌های نامزد اجاره به کلاینت‌ها، بررسی پینگ را روی آن‌ها انجام دهد.
PostgreSQL Support Library	متن‌باز Kea	این کتابخانهٔ هوک، پشتیبانی از استفاده از پایگاه(های) دادهٔ PostgreSQL را برای Backendهای Lease، Host و Configuration در Kea ارائه می‌دهد.
RADIUS	متن‌باز Kea	کتابخانهٔ هوک RADIUS به Kea اجازه می‌دهد با استفاده از سازوکارهای access و accounting با کارسازهای RADIUS در ارتباط باشد. سازوکار access می‌تواند برای کنترل دسترسی، تخصیص آدرس‌های IPv4 یا IPv6 خاصِ رزروشده توسط RADIUS، تخصیص پویای آدرس‌ها از مخزن‌های (pools) تعیین‌شده توسط RADIUS، یا رد کامل پیام‌های کلاینت استفاده شود. سازوکار accounting به کارساز RADIUS اجازه می‌دهد فعالیت دستگاه را در گذر زمان رهگیری کند.
RBAC	مشتریان پشتیبانی ISC	این کتابخانهٔ هوک پشتیبانی از پالایش دستورها بر اساس کنترل دسترسی نقش‌محور (Role-Based Access Control) را به کارسازهای Kea (شامل kea-dhcp4، kea-dhcp6 و kea-dhcp-ddns) اضافه می‌کند.
Run Script	متن‌باز Kea	این کتابخانهٔ هوک پشتیبانی از اجرای اسکریپت‌های خارجی را برای نقاط هوک خاص در پردازش بسته‌ها اضافه می‌کند. چندین متغیر محیطی صادرشده وجود دارند که در اختیار اسکریپت قرار می‌گیرند.
Statistics Commands	متن‌باز Kea	این کتابخانه دستورهای بیشتری را برای بازیابی آمارهای دقیق اجارهٔ DHCP، برای کارسازهای Kea DHCP که از یک پایگاه دادهٔ اجارهٔ مشترک بهره می‌برند، ارائه می‌دهد. این پیکربندی در استقرارهایی متداول است که به افزونگی سرویس DHCP نیاز دارند و از یک پایگاه دادهٔ اجارهٔ مشترک برای اجتناب از تکرار داده‌های اجاره بین کارسازهای DHCP استفاده می‌کنند. این کتابخانهٔ هوک آمارهای اجاره را برای هر زیرشبکه بازمی‌گرداند.
Subnet Commands	متن‌باز Kea	در استقرارهایی که پیکربندی زیرشبکه باید به طور مکرر به‌روزرسانی شود، این یک الزام حیاتی است که چنین به‌روزرسانی‌هایی بدون نیاز به پیکربندی مجددِ کامل یا راه‌اندازی دوبارهٔ کارساز DHCP انجام شوند. این کتابخانهٔ هوک امکان اعمال تغییرات تدریجی بر پیکربندی زیرشبکه، مانند افزودن یا حذف یک زیرشبکه را ممکن می‌سازد. همچنین امکان فهرست کردن تمام زیرشبکه‌های موجود و واکشی اطلاعات دقیق دربارهٔ یک زیرشبکهٔ انتخاب‌شده را فراهم می‌کند. دستورهای ارائه‌شده توسط این کتابخانه بر دیگر زیرشبکه‌ها یا پارامترهای پیکربندی که در حال حاضر توسط کارساز استفاده می‌شوند اثری نمی‌گذارند.
User Check	متن‌باز Kea	فهرست کاربران شناخته‌شده را از یک فایل می‌خواند. به کاربران ناشناخته، اجاره‌ای از آخرین زیرشبکهٔ تعریف‌شده در فایل پیکربندی اختصاص داده خواهد شد، برای مثال برای هدایت آن‌ها به یک پورتال محصور (captive portal). این عملکرد نشان می‌دهد که چگونه می‌توان از یک منبع خارجی اطلاعات برای اثرگذاری بر موتور تخصیص Kea استفاده کرد. این هوک بخشی از کد منبع Kea است و در دایرکتوری src/hooks/dhcp/user_chk در دسترس است.
