...DP for SIP, however from time to time this range isn't where Asterisk is opening the ports: We're at xxx.xxx.xxx.xxx port 8542 Answering with capability 0x2(GSM) Answering with capability 0x4(ULAW) Answering with capability 0x8(ALAW) This call has no audio, presumably because port 8542 is firewalled in the iptables on the server. Is there somewhere I'm missing to port a port range in sip.conf (shouldn't there be if there isn't?). Steve Radich BitShop, Inc. - http://www.bitshop.com

...but let them access internet on specified time window e.g lunch time. I plan to use iptables and squid to do block and web caching but I have no idea how to control access on time frame.

My firewal/proxy box will be CentOS 5.2 so I prefer something that can install via yum/rpm Thanks in advance!

...versa from Local2 one could see Local. Additionally, one could easily browse through the remote network as long as the user permissions were correct. With the same user name and password for the two domains there was no issue with authentication. Teh configuration was this: Local ==> IpTables firewall, FC4, with Samba, OpenVpn, Freshclam, Apache and Sendmail Local2 ==>IpTables firewal, FC4, with Samba, OpenVpn, Freshclam Then we had the firewall hacked on Local. The server was compromised and a NEW drive was put in place and reinstalled with Etch (Debian 4.0) The firewall was restored, di...

I spent several days (at least 20 hours) tying to get Fedora 11 Samba server going. I consulted every resource that I knew including this list. When I discovered that Fedora 11 Samba could be browsed immediately upon installation, and a simple reboot disabled this, I gave up. I decided to try Ubuntu. After intallation it took only five minutes of editing the smb.conf file to make my share fully

Hi! Some - few - providers are using IAX2 as a protocol. Most are using SIP. I know that there are advantages of IAX2 regarding multiple connections. But beside this I'm asking myself (and you all) why I should prefer IAX2 when my SIP connection is working. Are there differences in the performance? Bye! Michael
