Dear all,

Hi ! I have to carry out installation of a server to run oracle. Already One server is already working at site. This one needs to be a "standby" server.  If I create partitions on the standby server identical to the "main" server and then restore a backup taken from main server through cpio on standby server, will it start working exactly the same way the main is working ?

Also is there any way we can tell cpio to overwrite all files on target even when they are "read-only" ?

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

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 ?

I tried by including the internal ip and hostname but no improvement is there.

Hi Gaurav !

This is my /etc/hosts:

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.

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.

How to take tcp dump ? Can you please explain step by step ?

Hi All,

I need one piece of information/guidance:

Many of the "host based" laser printers (e.g. HP laserjet 1000 series, 1010 etc.) seem to give errors while printing on Linux ( some of the inbuilt drivers in linux also do not make these printers even print anything) when attached directly through USB interface.

For such printers some drivers are available at linuxprinting.com web site and seem to work better than drivers originally shipped with linux distributions.
If this driver works okay then how to configure the same printer as a network printer if it is attached to a windows box using same driver ?



Thanks In Advance

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

Thanks a lot , Ricky !!

Thanks Ricky.

A simple straight forward query - Squid is working fine in normal mode on my server. I want my clients to be able to do ftp through ftp clients/command line and also be able to exchange mail from web using outlook express.

Additionally if I install firestarter and say no to "enable sharing internet connection" will that give me what I need ?

Thanks Ricky !!

A few more queries , please:-
Can you please elaborate that under what conditions "normal" proxy be used and under what conditions the use of "Transparent" proxy is recommended ?

Also is it possible to open secured sites/sites where authentication is required  in Transparent proxy ? Also how to implement content filtering and access control under Transparent Proxy as what I feel is that under transparent proxy setup any one on the local  LAN wil have full access to internet ?

A typical problem with the combination of Squid and firestarter is :

Squid is working fine. When we install and run firestarter for the first time, it asks for "whether internet sharing is to be enabled ". If we say yes to this response then there will be two scenerios:
1.Internet access through NAT scripts generated by firestarter using iptables.
2. Internet access already available through the usage of Squid.

Which one will be used by the clients ?


My requirement is that I need my clients to have access to ftp servers on the internet, mail access via outlook/thunderbird , internet access via squid proxy because of caching advantage.



Thanks In Advance

Hi eveyone,

I need some clarifications regarding squid proxy as follows:-

1. Whether squid acts as "cache " proxy if operated in Transparent mode ?
2. What are the basic differences between normal and Transparent proxies ( except that clients need to be configured manually in case of normal proxy server) ?
3. Can we use squid for proxy application if a firewall is running on the same system ( for example firestarter). In case both are to be used, which one should be installed first and why ?
4. What exactly is the accelerator mode in squid ?



Thanks in advance
