I am limited however to 260 connections total - we are a major hub for dalnet and with a Pentium 120MHZ 64MB RAM we would like to use all 2000 available connections we can use with dalnet ircd under 64MB ram - here's what I've tried thus far Makefile in the Makefile, we've added CFLAGS = -D"FD_SETSIZE=1024" this however when compiled with a kernel of either max connections of 10, 64, 65 200 - will run the ircd for five minutes and crash (it has specified in the config.h max connections of 1024) I went to the kernel and tried a couple items such as the following: changing max connections from 10 to 64 tried 65 and 200 - no luck options "CHILD_MAX=1024" options "OPEN_MAX=1024" instead of the typical 128 (we tried 128 too) nothing works - is there ANY way we can get the file descriptors to accept all 1024 (preferrably the 2000 I know we can easily handle) - we are a major hub for the DALnet ircd network often holding half or more of that network together - phoenix.dal.net is also a listed DALnet server in the mIRC and serveral other irc client programs out there and is used by 230 users easily by 9 am every morning. Any help on this issue would be greatly appreciated. If you wish to test with your own servers or view the dalnet ircd code it can be located at ftp site ftp.dal.net/dalnet/server the current code it the irc2.8.21.mu3.dal4.2 - however on FreeBSD I cannot get that to run period - I'm still running a later version named irc2.8.21.mu3.dal4a -Leigh Gaffney WebMistress, IRC System Administrator phoenix.dal.net "Wolenczak" http://www.dal.net/ http://www.phoenix.net/~leigh
