[linux] loopback problem

[Marek Slebodnik]

 Zdravim 
 
 
 Na jednom stroji pozorujem jednu zvlastnost
 pri pristupe na loopback ssytem pouziva zdrojovu ip interfacu na ktorom
 je default route
 napr. pri ping 127.0.0.1 mi tcpdump ukaze 
 
 =========================================================================
 www  # tcpdump -ni lo proto \\icmp
 tcpdump: verbose output suppressed, use -v or -vv for full protocol
 decode
 listening on lo, link-type EN10MB (Ethernet), capture size 68 bytes
 13:00:25.814310 IP x.y.144.222 > 127.0.0.1: ICMP echo request, id
 52063, seq 23, length 64
 13:00:25.814354 IP 127.0.0.1 > 127.0.0.1: ICMP echo reply, id 52063, seq
 23, length 64
 13:00:26.814310 IP x.y.144.222 > 127.0.0.1: ICMP echo request, id
 52063, seq 24, length 64
 13:00:26.814353 IP 127.0.0.1 > 127.0.0.1: ICMP echo reply, id 52063, seq
 24, length 64
 ========================================================================
 
 pricom routy su taketo 
 
 =========================================================================
 www conf.d # ip ro
 192.168.10.0/24 dev eth1  proto kernel  scope link  src 192.168.10.1
 x.y.144.0/22 dev eth0  scope link
 127.0.0.0/8 dev lo  scope link
 default via x.y.144.1 dev eth0
 =========================================================================
 
 skusal som aj  127.0.0.0/8 dev lo  scope link  src 127.0.0.1 no malo to taky isty efekt.
 robi to problem najme pri mysql ,ked pri connecte vypapuluje 
 failed to connect to mysql server (server=127.0.0.1, userid=root):
 Host 'x.y.144.222' is not allowed to connect to this MySQL server
 
 
 
 Vdaka za kazdu uzitocnu radu.
