Medical Forum / General / Dentistry / August 2005Linux Dentrix Server (Samba)
<TABLE id=Table19 cellSpacing=0 cellPadding= width="100%"><TBODY><TR><TD vAlign=top>If anyone is using a snap serve or a linux box, and they want to speed up the audit trail report wit dentrix, then be sure to have fake oplocks = yes in the smb.conf file I learned this awhile back, then forgot about it. I am posting it her to help me remember that its the setting Ive always believed that if you write it down, and verbally speak it the chances of forgetting are a lot harder oplocks = n fake oplocks = ye I thought it was another setting throwing it off. Grrr [image: http://www.dentaltown.com/idealbb/images/smilies/1.gif] Without this setting its horribly slow, with it, its BLAZING FAST PS. It helps to enable window scaling, sack, and I raise the limit o the tcp auto tuner /etc/sysctl.con # Controls IP packet forwardin net.ipv4.ip_forward = net.ipv4.tcp_window_scaling = net.ipv4.tcp_timestamps = net.ipv4.tcp_sack = # increase TCP max buffer siz net.core.rmem_max = 1677721 net.core.wmem_max = 1677721 # increase Linux autotuning TCP buffer limit # min, default, and max number of bytes to us net.ipv4.tcp_rmem = 4096 87380 1677721 net.ipv4.tcp_wmem = 4096 65536 1677721 Tested with FC4, Kernel 2.6.12.5, and samba 3 </TD></TR></TBODY></TABLE -- Administrato I've used a few "network appliance" type Linux distributions on Dentrix and Open Dental and I've had good luck with almost all of them. As of late, I've been using the ClarkConnect developer distro because of its ease of use and user friendly HTML (web) interface. I still get a chuckle when I show up with this little cube shaped computer that has no keyboard, mouse or screen. Just a little 6X8X10 aluminum shaped box. Plug it in and you have a full Windows server, a web server, a mail server, a TRUE stateful firewall (none of this Netgear junk), a SQL server, an antivirus, VPN gateway, internet gateway, local / remote rsync and backup server, RAID drives... blah...blah...blah... :) If you've not tried one...download the ISO and give it a whirl. For about $600.00 you can put together a server that'll run circles around those 'enterprise level' Dells everybody touts. If nothing else, I like to see the deer in the headlights look on these "high tech" rep's faces when you show them one of these. With a little determination and a little reading, anyone can set one of these up. Anyhow, here's the spec: * Security / Networking DMZ and 1-to-1 NAT & Firewall Gateway Firewall Tools Intrusion Detection-snort Intrusion Detection Reports-snortalog Intrusion Prevention-snortsam Peer-to-Peer Traffic Manager DHCP Server FTP Server-proftpd Print Server-cups Windows File Server-samba Antispam-spamassassin Antispam Quarantine Tool-spamassassin-filter Antivirus-sophos Mail Relay for Road Warriors-pop-before-smtp Mail Server - POP and IMAP Mail Server - SMTP-postfix Webmail-squirrelmail * Web Server WebDAV Web Server-httpd apache Web Site Reports-awstats Caller ID Photo Gallery Slim Server * Administration Backup-bacula Backup/Restore System Settings-backuprestore Console Tool System Statistics-mrtg System Status-phpsysinfo System Watcher-syswatch * Filtering Banner Ad and Pop-up Filter-privoxy Content Filter-dansguardian Web Proxy-squid Web Proxy Reports-sarg * Connectivity Bandwidth Manager cc-bandwidth Caching DNS Server-dnsmasq Hosts File Manager VPN - IPsec VPN - PPTPd Wireless * Developer Developer Environment  Signaturebillkatz I just put a linux box together.. I like to build my own so I jus download fedora core 4, put on the newest kernel, the newest stabl samba, and start configuring Samba, Rsync\SSH, iptables, are working so far, and it is fast. S tired, need more sleep. For a samba client to do the audit trail that is fast, fake oplocks ha to be enabled. It sounds like some of these companies who put togethe samba have ran into the same problem I have. If someone is sellin samba out of the box, preconfigured, then it must have that in th smb.conf file, which is not there by default... It should be.. = -- Administrato |
