Thanks,

There are a lot of them:

-----------
[root]# ls /proc/sys/net/netfilter/
nf_conntrack_buckets
nf_conntrack_tcp_timeout_fin_wait
nf_conntrack_checksum
nf_conntrack_log_invalid
nf_conntrack_tcp_timeout_last_ack
nf_conntrack_count
nf_conntrack_max
nf_conntrack_tcp_timeout_max_retrans
nf_conntrack_expect_max
nf_conntrack_tcp_be_liberal
nf_conntrack_tcp_timeout_syn_recv
nf_conntrack_tcp_loose
nf_conntrack_tcp_timeout_syn_sent
nf_conntrack_tcp_max_retrans
nf_conntrack_tcp_timeout_time_wait
nf_conntrack_tcp_timeout_close
nf_conntrack_udp_timeout
nf_conntrack_generic_timeout
nf_conntrack_tcp_timeout_close_wait
nf_conntrack_udp_timeout_stream
nf_conntrack_icmp_timeout
nf_conntrack_tcp_timeout_established
------------

Which ones of them can i set to eliminate this error i have:

"kernel: nf_conntrack: table full, dropping packet" ?

Please, a hint or pointer would be much appreciated? I'm now using Fedora
8 and Squid with around 1000 users; i had no problem with previous
versions of Fedora when ip_conntrack was used -- i simply set
ip_conntrack_max = 32768.

Thanks,
Khem
