Hi I am trying to develop a VPN load tester on 2 RedHat Linux 6.2 boxes running the standard 2.2.14-5.0 kernal and 2.3.11 pppd for connections. We need to generate 1000 tunnels between these 2 boxes which are isolated in the lab with a device under test router in between them. The first 100 connections work fine. But after 100 instances of pppd are running in background, an attempt to fork out another one fails. The messages file contains these 3 lines-- Apr 5 08:21:52 BSI500-2 kernel: ppp: dev_alloc_name failed (-23) Apr 5 08:21:52 BSI500-2 kernel: ppp_alloc failed Apr 5 08:21:52 BSI500-2 pppd[5197]: ioctl(TIOCSETD): Too many open files in system(23) How can I get around this problem? As you might expect, increasing the kernal "Unix98 ptys" configuration parameter from 256 to 2048 made no difference. Same for doubling /proc/sys/fs/file-max from 4096 to 8192. Any help as to where to find this error in the ppp or kernal source files would also be appreciated. Thanks! -Gary -- To unsubscribe: mail -s unsubscribe [EMAIL PROTECTED] < /dev/null
