Prędkość Sieci Lan Podczas Przesyłania Spada

[przembond]

Witam mam taki problem z siecia gdybyscie mogli mi pomóc to było by fajnie

Mam postawiony serwer na fedora 2 i sambe kompy w sieci sie widza ale kiedy wysyłam pinga na serwer idzie jako TTL 64 kiedy wysyłam pliki na serwer to ida bardzo wolno transfer 120 kb co moze byc przyczyna prosze pomorzcie bo juz nie wiem co robic pozdrawiam Przemek

[mynus]

kiedy wysyłam pinga na serwer idzie jako TTL 64

a co w tym dziwnego? linuksy wysylaja pakiety wlasnie z TTL 64, ale jak bardzo chcesz to mozesz to zmienic (windows maja TTL 128)

 

kiedy wysyłam pliki na serwer to ida bardzo wolno transfer 120 kb

dosc duzo, bo nie znam specyfikacji Twojej sieci:

 

-typ kabli (co to jest skretka czy BNC, jak skretka to jaka? jaki typ? moze zly kabel wybrales, zle zacisniety, etc.)

-jakie karty sieciowe (moze ktoras jest uszkodzona)

 

--ograniczenie ruchu na serwerze, moze cos wlaczyles, oprocz tego sprawdz logi, tam zawsze jest cos ciekawego napisane,

-sprawdz tcpdump, iptraf, zobacz co jest ejszcze wysylane

[przembond]

HEJ

wiec tak jest to skrętka karta 3com905 dioda swieci sie na niej jak by praowała z predkoscia 100

kiedy pinguje na karty w serwerze ida jako 64 ( ping 192.168.0.1 {to jest IP serwera } i nie wiem czy tak powinno byc ale moge wysyłac pinga na numer 127.0.0.1 nie wiem co to jes za IP. Jak sprawdzic "ograniczenie ruchu na serwerze"

. jestem nowym urzytkownkikiem (_linuxa_ → Linuksa) ORT podoba mi sie ale no własnie

[mynus]

1. adres IP 127.0.0.1 to tak zwana petla zwrotna, zawsze oznacza ona Ciebie. i Twoj komputer

(czasmai programy z tego korzystaja), na kazdym komputerze pingujac ten adres pingujesz sam siebie.

 

2. na kazdym linuksie dostaniesz pinga z TTL 64, windows wysyla TTL 128, ale dalej nie wiem o co chodzi Ci z tym TTL. To nie jest predkosc przesylania danych tylko czas zycia pakietu.

 

(ping nie sprawdza predkosci przesylania danych)

[przembond]

Ok czyli TTL taki powinien byc ale problem mi pozostał kiedy kopiuje duże pliki to jest np 500 mB na serwer transfer spada do 400 kb/s a zaxczyna sie od 30000kb/s

jak sprawdzic czy mam jakies ograniczenie na serwerze przesyłam smb conf

 

może cos tu mam nie tak

 

 

smb.config

 

# This is the main Samba configuration file. You should read the

# smb.conf(5) manual page in order to understand the options listed

# here. Samba has a huge number of configurable options (perhaps too

# many!) most of which are not shown in this example

#

# Any line which starts with a ; (semi-colon) or a # (hash)

# is a comment and is ignored. In this example we will use a #

# for commentry and a ; for parts of the config file that you

# may wish to enable

#

# NOTE: Whenever you modify this file you should run the command "testparm"

# to check that you have not made any basic syntactic errors.

# This option is important for security. It allows you to restrict

# The following are needed to allow password changing from Windows to

# update the Linux system password also.

# NOTE: Use these with 'encrypt passwords' and 'smb passwd file' above.

# NOTE2: You do NOT need these to allow workstations to change only

local master = no

 

# OS Level determines the precedence of this server in master browser

# elections. The default value should be reasonable

# All NetBIOS names must be resolved to IP Addresses

# 'Name Resolve Order' allows the named resolution mechanism to be specified

# the default order is "host lmhosts wins bcast". "host" means use the unix

# system gethostbyname() function call that will use either /etc/hosts OR

# DNS or NIS depending on the settings of /etc/host.config, /etc/nsswitch.conf

# and the /etc/resolv.conf file. "host" therefore is system configuration

# dependant. This parameter is most often of use to prevent DNS lookups

# in order to resolve NetBIOS names to IP Addresses. Use with care!

# The example below excludes use of name resolution for machines that are NOT

# on the local network segment

# - OR - are not deliberately to be known via lmhosts or via WINS.

# Windows Internet Name Serving Support Section:

# WINS Support - Tells the NMBD component of Samba to enable it's WINS Server

wins server = w.x.y.z

 

# WINS Proxy - Tells Samba to answer name resolution queries on

# behalf of a non WINS capable client, for this to work there must be

# at least one WINS Server on the network. The default is NO.

wins proxy = yes

 

# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names

# via DNS nslookups. The built-in default for versions 1.9.17 is yes,
