waduhh... kok sampek topologi segala brooo...

Pak.. Mas..

kenapa squid saya sering banget seperti macet, dan kemudian tampil seperti ini :


Padahal PDNSD berjalan dengan normal, saya cek pakai squid -k parse, tidak ada error,
saya cek pakai cara lain, lalu dibilang ada masalah:
root@ubuntuproxy1:~# tail /var/log/messages
Jul 2 14:51:54 ubuntuproxy1 squid[866]: Squid Parent: child process 870 started
Jul 2 14:51:55 ubuntuproxy1 squid[809]: Squid Parent: child process 812 exited due to signal 6

Jul 2 14:52:07 ubuntuproxy1 squid[809]: Squid Parent: child process 1013 exited with status 1

trus di cek disini kok dibilang jalan:

mohon bantuannya dong...pusing sama cekuit nih ..

cek dns namenya...

Akhirnya install ulang Mas, lupa salahnya dimana, setelah install baru dan mulai konfigurasi pelan2 lagi, eh lancar..

cara cek dns name nya gimana mas ?

Kayaknya agar squid optimal di-server masing2, perlu pake yg versi compile sendiri, shg kinerja squid bisa optimal sesuai dg spek komputernya.
Saya sudah membuktikan nih, sebelumnya pake yg standar ( dari repositori Ubuntu ), request disk ratiosnya (60menit) paling tinggi sekitar 30%.
Setelah compile sendiri, bisa meningkat mencapai 70% padahal squid.conf yg dipake tetep sama.
Ini hasil squidclient mgr:info yg sekarang :

padahal server saya pas-pasan, Pentium 3 733 RAM 384, melayani 5 client + server LTSP

Ini contoh tutor yg bagus untuk compile squid :
Compile squid 2.7stable9 by mastah Rh354

binun ada yg bilang pake perasaaan ada yg bilang cari hit paling tinggi

@Zitux : Mungkin digabung, waktu browsing gimana rasanya lebih cepat akses apa gak, trus dicek pake squidclient ...

jadi inget tutor2 lama gw yg lupa dibackup waktu pindah hostingan T.T

gak nemuin titik temu nya ya

mohon di koreksi biar tidak tersesat di jalan

salam
sabar

Sebenarnya cache squid lebih baik dibuatkan partisi tersendiri, supaya akses file cache nya lebih cepat... CMIIW

Coba cache di RAM dikecilkan,

maximum_object_size_in_memory 32 KB
menjadi
maximum_object_size_in_memory 512 bytes ( atau 1 s/d 4 KB, dicoba-coba saja )

juga :
cache_dir aufs /usr/local/squid 10400 48 256
menjadi
cache_dir aufs /usr/local/squid 10400 24 256

dari rumus 'umum' :
(((10400000/13)/256)/256)*2 = 24.4 == 24

stop squid, hapus/kosongkan cache dir nya trus build lagi cache dir nya :



Dari saya cuma itu, maklum baru bisa copy & paste

Teng_q Om udah ngebalas

lagsung praktek,,,, hasilnya akan sy posting lagi
satu lagi nich om, selain perintah tail -f untuk melihat performa squid apalagi yach ???
maklum baru belajar Ubuntu dengan squid :-)

mas, om, kk, cemua ,,,, help nich,,,, masih teyus miss sdh 1 minggu run
rencana mau nambah hardisk biar cachenya ke hardisk baru
perintahnya bgaimana yach



mohon bantuannya biar tidak tersesar di jalan

konfigurasi squid nya gw liat koq kek ada yg salah n dobel2 y...

maklum nubi

bagian yang mana om ?????

malam om,,,KK,,,Mbah,,, Master tak henti-hentinya saya bertanya ke forum ini agar sy tidak tersesat

trus yang ditanyakan apa? itu software untuk mail server bukan ya? maaf kl boleh tau,gmna cara memulai bikin mail server gan? maklum masih amatir ni bru pke Linux

@bro sabar, mending trit yg lama dilanjutkan, jangan buat trit baru yg sejenis, ok
