Hi, I have squid 2.5STABLE12 and linux SUSE 10.1. When I use authentication helper NCSA my proxy server stops and I receive information in cache.log (my firewall is disabled, in squid.conf cache_effective_user squid, the owner of file ncsa_auth is squid): 2006/07/10 07:49:18| Starting Squid Cache version 2.5.STABLE12 for i686-pc-linux-gnu... 2006/07/10 07:49:18| Process ID 9077 2006/07/10 07:49:18| With 4096 file descriptors available 2006/07/10 07:49:18| DNS Socket created at 0.0.0.0, port 32768, FD 6 2006/07/10 07:49:18| Adding nameserver 192.168.1.70 from /etc/resolv.conf 2006/07/10 07:49:18| Adding nameserver 194.204.159.1 from /etc/resolv.conf 2006/07/10 07:49:18| helperOpenServers: Starting 5 'ncsa_auth' processes 2006/07/10 07:49:18| ipcCreate: /usr/sbin/ncsa_auth: (1) Operation not permitted 2006/07/10 07:49:18| ipcCreate: /usr/sbin/ncsa_auth: (1) Operation not permitted 2006/07/10 07:49:18| ipcCreate: /usr/sbin/ncsa_auth: (1) Operation not permitted 2006/07/10 07:49:18| ipcCreate: /usr/sbin/ncsa_auth: (1) Operation not permitted 2006/07/10 07:49:18| User-Agent logging is disabled. 2006/07/10 07:49:18| Referer logging is disabled. 2006/07/10 07:49:18| ipcCreate: /usr/sbin/ncsa_auth: (1) Operation not permitted 2006/07/10 07:49:18| Unlinkd pipe opened on FD 16 2006/07/10 07:49:18| Swap maxSize 102400 KB, estimated 7876 objects 2006/07/10 07:49:18| Target number of buckets: 393 2006/07/10 07:49:18| Using 8192 Store buckets 2006/07/10 07:49:18| Max Mem size: 8192 KB 2006/07/10 07:49:18| Max Swap size: 102400 KB 2006/07/10 07:49:18| Local cache digest enabled; rebuild/rewrite every 3600/3600 sec 2006/07/10 07:49:18| Rebuilding storage in /var/cache/squid (DIRTY) 2006/07/10 07:49:18| Using Least Load store dir selection 2006/07/10 07:49:18| Set Current Directory to /var/cache/squid 2006/07/10 07:49:18| Loaded Icons. 2006/07/10 07:49:18| Accepting HTTP connections at 0.0.0.0, port 3223, FD 18. 2006/07/10 07:49:18| Accepting ICP messages at 0.0.0.0, port 3130, FD 19. 2006/07/10 07:49:18| HTCP Disabled. 2006/07/10 07:49:18| Accepting SNMP messages on port 3401, FD 20. 2006/07/10 07:49:18| WCCP Disabled. 2006/07/10 07:49:18| Ready to serve requests. 2006/07/10 07:49:18| WARNING: basicauthenticator #1 (FD 8) exited 2006/07/10 07:49:18| WARNING: basicauthenticator #2 (FD 9) exited 2006/07/10 07:49:18| WARNING: basicauthenticator #3 (FD 10) exited 2006/07/10 07:49:18| Too few basicauthenticator processes are running FATAL: The basicauthenticator helpers are crashing too rapidly, need help!
