Hi again. I already asked that question once, but then I didn't get any helpful answers... Following problem: I'm in the intranet at my office, and want to work on a remote server. Let's call him jasper. So, I'm on jasper an make a "xspread". Now I get the following answer: xspread: Can't open display client84.xxxx.xx:0 It doesn't matter whether I use ssh or rlogin or rsh to log in to jasper, it simply doesn't work. My firewall log says: Sep 5 11:17:55 memphis kernel: Packet log: rulchain REJECT eth0 PROTO=6 xxx.xx.xxx.xx:60972 xxx.xx.xxx.xx:6000 L=44 S=0x00 I=5353 F=0x4000 T=255 SYN (#5) Sep 5 11:17:56 memphis kernel: Packet log: rulchain REJECT eth0 PROTO=6 xxx.xx.xxx.xx:60974 xxx.xx.xxx.xx:6000 L=44 S=0x00 I=5354 F=0x4000 T=255 SYN (#5) Sep 5 11:17:57 memphis kernel: Packet log: rulchain REJECT eth0 PROTO=6 1xxx.xx.xxx.xx:60975 xxx.xx.xxx.xx:6000 L=44 S=0x00 I=5355 F=0x4000 T=255 SYN (#5) Sep 5 11:17:58 memphis kernel: Packet log: rulchain REJECT eth0 PROTO=6 1xxx.xx.xxx.xx:60976 xxx.xx.xxx.xx:6000 L=44 S=0x00 I=5356 F=0x4000 T=255 SYN (#5) Sep 5 11:17:59 memphis kernel: Packet log: rulchain REJECT eth0 PROTO=6 xxx.xx.xxx.xx:60977 xxx.xx.xxx.xx:6000 L=44 S=0x00 I=5357 F=0x4000 T=255 SYN (#5) Now, how can I solve that problem? Also, I wonder why the outgoing port on jasper is steadily inceasing by one, with each attempt to connect...? Any help appreciated! TIA markus
