Hi, I can not send mail tru my hosting account on hostgator. every mail I try to send.. time out error. they say that one of the terminals is sending invalid TCP packets to server on port 25. I use standard outlook express and there are no malware,spyware or anything like it on those terminals. How can I identify this terminal / problem ? this is what they sent me Aug 14 02:35:31 commander kernel: IVD-TCP-03 : IN=eth0 OUT= MAC=00:13:72:40:3f:6f:00:17:0e:3b:c2:bf:08:00 SRC= 85.105.xxx.xx DST=74.52.xx.xx LEN=1500 TOS=0x00 PREC=0x00 TTL=103 ID=23123 DF PROTO=TCP SPT=3761 DPT=25 WINDOW=64974 RES=0x00 ACK URGP=0 I have tried to match the mac address for those terminals to the MAC=...... in the above log, but the format is different. I guess thats not the mac address.. any clues ?
Try switching to port 26 on your mail client. Hopefully they have their mail server running on that port
Thanks.. Actually I did try that.. didnt do any good.. We have shutted down whole system.. And tried with notebook with direct connection to modem.. could not send mail again. I think its has got nothing to do with our side of the system.
