Author Topic: Network Browsing Problem With Samba Server (Read 7051 times)

Hi All !,

I am facing problem with Samba.
I am using CentOS 4.4 and using samba 3.0.10 that is part of standard distribution. My windows clients can see the Samba server and share files as desired without a problem.

If I go to Linux server running Samba and select Computer and then Network --- the cursor keeps appearing in the
"network " screen and the "Windows Network" icon appears after about 20 Minutes !!!!!

Is there any way we can reduce this time to some real time ?

Thanks in Advance

Can you bring tcp dump while you open shares from samba ?

Also check if there is any packet loss in data transfer ?

One more input here!!

Samba server is having two ethernet cards . eth0 is connected to internet and eth1 is connected to internal network.

If I disable eth0 and try browsing the network --It immediately opens the window having "Windows network". The moment I enable eth0 again , the first network browsing window takes almost 20 minutes to come up.

I have not used samba from long but somewhere in its config file you can specify that which eth. should bind itself to.

Btw, now its clear that it actually also try to query net (as I expected and hence was asking for tcpdump to figure out certain possibilities) .

BTW, tcpdump is nice tool , you can see its nice usage info at ..

Here's my amb.conf file:-

[global]

workgroup = MYGROUP
server string = Samba Server
printcap name = /etc/printcap
load printers = yes
printing = cups
log file = /var/log/samba/%m.log
max log size = 50
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
interfaces = eth1
bind interfaces only = Yes
local master = yes
preferred master = yes

#============================ Share Definitions ==============================
idmap uid = 16777216-33554431
idmap gid = 16777216-33554431
template shell = /bin/false
winbind use default domain = no
[homes]
comment = Home Directories
browseable = no
writable = yes

[printers]
comment = All Printers
path = /var/spool/samba
browseable = no
# Set public = yes to allow user 'guest account' to print
guest ok = no
writable = no
printable = yes

Please correct me where I am going wrong.

ok.........

So u have two ethernet card

eth0 and eth1

eth0--------------> Connected to internet.

eth1--------------> Connected to internal LAN.

please tel me your public IP ,the gateway at eth0

and the gateway at eth1

and the gateway of all clients connected to LAN

All Clients computers gateway should be your internal ip of eth1........

Please let me know the whole senerio......

Gaurav

The interface eth0 is connected to internet and the IP/DNS etc are configured dynamically.
All the clients on the LAN have gateway as the ip of eth1. All clients can share the disk and browse very well. It is only the server that has an issue of browsing.

I feel that if some how we can specify only eth1 to be configured in SAMBA the problem might get sorted out. But how to do that -----is the real problem ?

Hmm...............................

I think its a problem at the gateway at public NIC give one more gateway there not default as ur internal ip i.e of eth1

Your query is:

"I feel that if some how we can specify only eth1 to be configured in SAMBA the problem might get sorted out. But how to do that -----is the real problem ?"

But u have already configured samba with eth1 itself:

Here's ur smb.conf file

Any comment Ricky?

Perfectly okay. But it does not seem to work.
The moment I disable eth0 interface manually, the "first" network window appears immediately.
