Hello.
I have the same problem after enabling of range 30000:35000.
csf configuration:
# Allow incoming TCP ports
TCP_IN = "20,21,22,25,53,80,110,143,443,465,587,993,995,2077,2078,2082,2083,2086,2087,2095,2096,2626,81,30000:35000"
# Allow outgoing TCP ports
TCP_OUT = "20,21,22,25,37,43,53,80,110,113,443,587,873,2086,2087,2089,2703,81"
in pure-ftpd uncommented the PASSV range
PassivePortRange 30000 50000
test of csf:
perl /etc/csf/csftest_pl
Testing ip_tables/iptable_filter...OK
Testing ipt_LOG...OK
Testing ipt_multiport/xt_multiport...OK
Testing ipt_REJECT...OK
Testing ipt_state/xt_state...OK
Testing ipt_limit/xt_limit...OK
Testing ipt_recent...OK
Testing xt_connlimit...FAILED [Error: iptables: Unknown error 18446744073709551615] - Required for CONNLIMIT feature
Testing ipt_owner/xt_owner...OK
Testing iptable_nat/ipt_REDIRECT...OK
Testing iptable_nat/ipt_DNAT...OK
RESULT: csf will function on this server but some features will not work due to some missing iptables modules [1]
I have two Cpanl+csf VPSes on Openvz. One of VPSes returns "ok" during the Testing xt_connlimit. The Second VPS returns the following result:
Testing xt_connlimit...FAILED [Error: iptables: Unknown error 18446744073709551615]
I have tried to reboot VPS, but no luck. Is the problem in xt_connlimit ? How to fix ftp for my users ?
Thank you for any help
