When I ssh (or ssh -X or ssh -Y) to my Suse SLED11-3, with my Fedora20 computer, each time I type a caracter on my Fedora console, this line (or similar) :
Jan 8 12:19:29 newwind-calc kernel: [74632.467271] SFW2-IN-ACC-EST IN=eth0 OUT= MAC=50:16:7e:37:64:2b:d4:3d:7e:97:0a:bd:08:00 SRC=IP of Fedora Computer DST=10.2.2.253 LEN=52 TOS=0x10 PREC=0x00 TTL=64 ID=24963 DF PROTO=TCP SPT=43767 DPT=22 WINDOW=16465 RES=0x00 ACK URGP=0 OPT (0101080A04654FF4011C02E9)
is appended to the /var/log/firewall file on the Suse computer. The file size is in Go by the end of the day. This bother me quite a lot…
I tried to find informations on the “SuSEfirewall2” and tried to add to “/etc/sysconfig/SuSEfirewall2”
FW_TRUSTED_NETS="IP of Fedora Computer"
FW_ALLOW_INCOMING_HIGHPORTS_TCP="ftp-data" # was: yes
FW_ALLOW_INCOMING_HIGHPORTS_UDP="dns" # was: yes
FW_ALLOW_PING_FW="no" # was: yes
as I saw recommanded I dont remember where. This did not change a thing.
I am not (at all) familiar with firewall configuration. Moreover, I can not acces the “Firewall” on Yast. When I clic it, nothing happens.
Thank you for your help ! I will provide any information missing as needed, but please give me details on how to optain each piece of information
