Hi everyone, I have a problem with SuSE Proxy Suite (in front of an ftp-server) when communication with client behind another proxy server (a delegate 8.5.5). Communication with other clients works without any problems, active or passive, the SuSE Proxy is configured for active and passive ftp. My network looks like this: external interface proxy (SuSE Linux 8.1, SuSE Proxy Suite) internal interface (10.0.0.254) | | ftp-server (10.0.0.200) When connecting from a client behind the delegate-proxy the logfile looks like this (where 172.16.0.1 is the IP of the delegate-proxy, 10.0.0.254 is the internal IP of the SuSE Proxy): ftp-child [19569] <11/26-12:43:14> USER-INF connect from 172.16.0.1 ftp-child [19569] <11/26-12:43:14> USER-INF 'USER USERNAME' from 172.16.0.1 ftp-child [19569] <11/26-12:43:14> USER-INF reading data for 'USERNAME' from cfg-file ftp-child [19569] <11/26-12:43:14> TECH-DBG from Server-PI (3): '220 SERVERNAME.' ftp-child [19569] <11/26-12:43:14> TECH-DBG from Server-PI (3): '331 Password required for USERNAME.' ftp-child [19569] <11/26-12:43:14> USER-INF 'PASS XXXX' from 172.16.0.1 ftp-child [19569] <11/26-12:43:14> USER-INF 'PASS XXXX' from 172.16.0.1 ftp-child [19569] <11/26-12:43:14> TECH-DBG from Server-PI (3): '230 User USERNAME logged in.' ftp-child [19569] <11/26-12:43:14> USER-INF 'PWD' from 172.16.0.1 ftp-child [19569] <11/26-12:43:14> TECH-DBG from Server-PI (3): '257 "/USERNAME" is current directory.' ftp-child [19569] <11/26-12:43:14> USER-INF 'SYST' from 172.16.0.1 ftp-child [19569] <11/26-12:43:14> TECH-DBG from Server-PI (3): '215 SERVERSYSTEM' ftp-child [19569] <11/26-12:43:20> USER-INF 'PORT 172.16.0.1:4568' from 172.16.0.1 ftp-child [19569] <11/26-12:43:20> USER-INF 'LIST' from 172.16.0.1 ftp-child [19569] <11/26-12:43:20> TECH-INF 'PORT 10.0.0.254:54975' for 172.16.0.1 ftp-child [19569] <11/26-12:43:20> TECH-DBG from Server-PI (3): '200 PORT command successful.' ftp-child [19569] <11/26-12:43:20> TECH-ERR can't connect Cli-Data for 172.16.0.1 ftp-child [19569] <11/26-12:43:50> USER-INF closing connect from 172.16.0.1 after 36 secs - read 0/0, sent 0/0 byte/sec Has anybody experienced something similar? How can I or the admin of the delegate-proxy solve this? This has also happened to me with another proxy on the other side, unfortunately they did not wanna tell me what technology they use...
