MRTG negeneruje obrazky

[Jirka Kubík]

Ahoj, 

mam problem s MRTG. Uz se mi ho sice nejak povedlo nainstalovat a rozchodit, ale bohuzel negeneruje zadne obrazky. Fyzicky tam .png soubory jsou, ale jsou prazdne, maji asi 75 bytu ... Po spusteni to vypada asi takhle

[root na server bin]# mrtg mrtg.cfg
gd-png:  fatal libpng error: Invalid filter type specified
gd-png error: setjmp returns error condition
gd-png:  fatal libpng error: Invalid filter type specified
gd-png error: setjmp returns error condition

Nevite nekdo co znamenaji tyhle hlasky ? Lepe receno co je zpusobuje ?

Konfigurak vypada takhle
