مشكلة عندي جديدة في لينكس في ال Network

[becatcho]

بصوا يا جماعة انا كان ليا موضوع قبل كدا بخصوص squid بس خلاص ظبطت المشكلة الي فيه المهم هو هو نفس السيرفر وفي كارتتين نيتك ورك بس المرة دي الموضوع مالوش دعوة بال squid
المرة دي لما باجي اعمل ريستارت لل network بالكوماند ده:
etc/init.d/network restart
تمام الاول كانت بتعمل عادي
دلؤتي بتعمل وبتطلع كلام كتير جدا ملخصه ان الاي بي بتاع الكارتتين used في حد تاني واخده بس الاكيد ان ده مش حقيقي لان انا لما بفصل السيرفر ده واعمل بنج لل اتنين اي بي مش بلاقيهم الا لو هو موجود فانا متوقع على حد علمي البسيط ان في مشكلة حصلت ان فيه كوفيجريشن مثلا متكررة في مكانين او في كاش معلق حاجة كدا يعني لو حد عنده معلومة ياريت يقولي وابقى شاكر جدا

[becatcho]

مش ممكن يا جماعة عشرين واحد شافوا الموضوع ولا واحد رد باي حل للدرجة دي مشكلتي صعبة ولا ايه؟
:ah46::ah46::ah46:

[Nightspy]

يا اخى الفاضل ممكن يكون جهاز واخدة و لاكن الFirewall لا يسمح الخاص بالجهاز لا يسمح بعمل Ping

راجع الDHCP Server

و خلى الاتنين ip دول Exclude

[becatcho]

ما هما فعلا معمول ليهمexclude علما بأن وحد فيهم real ip ثانيا على فكرة ده بيطلع كمان ده في local loop ثالثا الفايرول انا قالفله وهي هي

[Nightspy]

ممكن اشوف الoutput for ifconfig

[becatcho]

there is the output

ايه يا جدعان محدش رد على موضوعي تاني ليه؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟

[hamoodii_86]

اخي اذهب الى الفولدر التالي

/etc/sysconfig/network-scripts

وجوف اذا كان موجود اكثر من فايل للنتورك كارد الي عندك مثلا ifcfg-eth0 وما يكون في حاجه ثانيه لل eth0 غير هذا الفايل اذا فيه اسمحه وتخلي بس الاصليifcfg-eth0 وكذلك نفس الحال اللكارد الثاني

وبعدين اعمل ريستارت لل dhcp server و بعدين للنتورك سيرفس

وخبرني شنو يصير معاك

[becatcho]

مفيش اي حاجة جوه
/etc/sysconfig/network-scripts
كله عادي مفيش تكرار اما بالنسبة لل dhcp فا اصلا هو مالوش علاقة بيه لان الاي بي الي واخده اللينكس بره ال range بتاع ال dhcp

[becatcho]

ايه يا جدعان محدش بيرد على الموضوع ليه كدا
:ah8::ah8::ah8::ah8:

[Nightspy]

بجد الموضوع محير

طيب ممكن نشوف الoutput بعد كتابة Service network restart

بالاضافة للملف الخاص بالeth0 or 1 تحديدا الخاص بالمشكلة وسوف تجدة داخل هذا الpath
/etc/sysconfig/network-scripts

[becatcho]

بالنسبة service network restart
هو ده ال output بتاعه بس متتخضش ولو شفت حاجة كدا 192.xxx.xxx.xxx دي انا الي مغيرها بدل الاي بي الحقيقي تمام
