Hi All, I am new to R and want to use R to solve search problems (like Traveling salesman problem, finding nearest neighbor, hill climbing). Is this possible in R? To start with I want as follows. Find five float numbers whose sum is is equal to their product which should be 8000. x + y + z + p + r = 8000 x * y * z * p * r = 8000 Regards, Ambikesh Jayal. School of IS, Computing & Maths,

Has anyone had any success in getting Samba to correctly restart logging to the log files with the default logrotate setup (or even a modified one) from RedHat? The default setup is to move the files to another location, create a new file for Samba to fill, then send the daemons a HUP signal. I've tried some of the options that can be used in the logrotate.d/samba file (nocreate and

Does anyone have any log analysis tools? I'm currently configured with "log file = /usr/local/samba/var/log.%m", which makes identifying issues with any one client easy, but doesn't provide me with an overall picture of what has been happening. What I'd like to be able to produce is a report showing, for a given unit time, the total number of clients that have connected,

The shared mem size option is set to 102400 by default and change is discouraged: The man page (1.9.18p10) says: This parameter is only useful when Samba has been compiled with FAST_SHARE_MODES. It specifies the size of the shared memory (in bytes) to use between smbd processes. You should never change this parameter unless you have studied the source and know what you are doing.

We are moving from a PCNFS client to SMB client environment and hence moving from NFS for our Sun fileservers to Samba. I have seen figures indicating Samba is as good NT for SMB service. However what we are concerned with is: a) relative performance of Samba vs Sun's NFS b) loading on servers with lots of active connections (and hence lots of smbds). Do you need more memory than with

Hi, I've install Samba on AIX 3.2.5 and I'd like to know if there are large companies using Samba ? What's the size of your company ? How many users ? Do you know a limit of Samba ? (performances) Thanks Vincent Ceriani

I have just been upgrading my Samba servers from 1.9.18p10 to 2.0.6 So far as I can tell users have been happy (or at least not noticed!). Our clients are almost exclusively NT 4.0 (most at SP5). Our servers are Suns running Solaris 2.5.1 and 7. On upgrading 2 of our busier servers (for admin - home directories and NT binaries), I observed a considerable increase in server load. Home server

I just thought I'd throw this out there because it doesn't seem normal to me. We have 2.0.5a on AIX 4.3.2. We initially tried to increase the shared mem size to 4MB. This would not happen until we rebooted AIX. Then smbstatus reported a 4MB shared mem size. Now we are trying to decrease it because we will only need about 2MB and it won't reduce. I suspect it will when we reboot

Hi, I've been asked to research the possibility of changing our site from Novell to Samba. We've got 10,000+ client machines with about 30,000 users and currently use about 200-300 novell servers. I'm reasonably familiar with Samba but not on this scale. If anyone can point me towards a similar site then I'd be grateful. Currently we have a accouting system for each user for

Current situation: a) lots of Windows NT 4.0 workstation clients b) quite a few Samba 1.9.18p10 servers running on Suns c) 1 Samba server running as WINS server d) NO Windows Servers e) 1:1 correspondance between Netbios names and DNS names f) DHCP currently tells the Windows machines the WINS server. Problem: If WINS server goes down, every Windows NT workstation can not mount anything

We run a Network of Suns (running Samba) and PC-NT (version 4, sp3) machines, at work, and find it very annoying to be unable to change the file permissions of files from NT on the Suns. Is there any way to change the permissions from NT file explorer or otherwise ? Dave Kirkby

When the students arrive in a few weeks, we will have several thousand registered samba users and (we anticipate) several hundred simultaneous Samba connections. (This will be our first period of significant Samba use.) Our management folks are asking about collecting periodic Samba usage figures. This is a bit vague, but something like a rolling count of simultaneous connections, per-user

In problem-fixing, the "nicest" problems are those reproducible on demand. Alas, this one is not nice. System: Samba 2.0.6 on Solaris 2.7 (also see similar on Solaris 2.6). Symptom (user perspective): PC suddenly, spontaneously freezes and eventually the connection times out. Symptom (log file): [2000/02/15 09:27:30, 0] ../lib/util_sock.c:read_socket_data(474)

Hi all, Can someone explain exactly how Windows does naming resolution ? Here's my setup and my problem ... Windows 95 / Solaris 7 network with Samba 1.9.18 Windows PC with local IP and DNS servers defined and WINS turned off. I have NetBIOS using DNS for name resolution. I have a samba server X which about 50 PC's in our dept use. I want to move the services to machine Y so that I

I have searched the archives and the internet and found nothing on this topic but I know it's a known issue. Second I would like to say this has nothing to do with NTDOM. I am running a samba server 2.0.0 on a freebsd box. I am connecting to the server using windows 9x and NT clients. I have hacked the windows registries to enable clear text passwords across the lan. The problem is when

I can't answer any of this, but the following was taken from a thread on the "Novell Technology Transfer Partners List <NOVTTP@LISTSERV.SYR.EDU>" and passed over to me by my boss... Any comments/refutations/etc most definitely accepted... Please note that *I'm* the Senior Unix Systems Administrator at the University I work at, and have been moving us towards Samba since I

On our most heavilly loaded Samba server (running 1.9.18p10 under Solaris 2.5.1) we have got occaisional meltdowns with load average rocketing to 100+. The evidence indicates lots of smbd processes running. Syslogs indicate lots of: Nov 12 12:48:35 zeus.brunel.ac.uk smbd[21572]: Failed to set socket option SO_KE EPALIVE Nov 12 12:48:35 zeus.brunel.ac.uk smbd[21572]: Failed to set socket

Environment: Solaris 2.5.1 Samba 1.9.18p3 We run samba from inetd (no special reason - just how its been done in the past). Then on one server we got masses of Samba daemons running (up to 40 as a time trying to run - load average 40+!), giving following complaints: Sep 28 14:39:06 zeus.brunel.ac.uk smbd[10728]: standard input is not a socket, a ssuming -D option Sep 28 14:39:06

Nguyen Cao Dat asked about this: ERROR! Out of file structures - perhaps increase MAX_OPEN_FILES? As it happens I have started getting them too - on a PC Application server - the cause seems to be lots of files needed to be open to run applications - Lotus apps seems to be a particular culprit, but experiments indicate that even opening help on Microsoft Word opens 13 files! MAX_OPEN_FILES

I realise that Samba is a voluntary effort and keeping Web Sites upto date may not be everyone's favourite occupation, but there appear to be a number of things missing or wrong: a) There is no contact info for the WebSite I could discern - hence posting here. b) There is still reference to samba-bugs@samba.org address - which I have been informed by it, is now dead. So may be this could be
