Divny hlasky ve /var/log/messages - pomuzete s identifikaci?

[Libor Chocholaty]

Ahoj,

nachazim divne hlasky v syslogu a nevim co to je. Pomuzete s
identifikaci?
Zacalo to "samo od sebe" dneska v 18:42. Asi to bude mit nejakou
souvislost se mnou, ale jeste jsem podobne zaznamy nevidel. poradite, co
to je?

Adresy:
1.2.3.4 - pocitac, na kterym se to objevuje
1.2.3.5 - pocitac odkud jsem tam pripojenej
6.7.8.9 - pocitac odkud jsem testoval pripojovani odjinud

Diky, Libor Chocholaty
