...dump and wireshark traces, as you suggested, and here is what I have found: When an Ethernet frame that is less then 60 bytes in size goes through the network, it is padded with 0x00 bytes until it has 60 bytes in length (64 with the frame check sequence). When this kind of padded frames goes from centos1 VM through the linux bridge br0 to the windows host, the IP and TCP headers in those frames wrongly consider the 0x00 padded bytes as part of the user data, therefore the upstream protocol (SSH in my case) tries to interpret them, and this is why Putty hangs. Those 0x00 padded bytes are at the laye...

...odify isolinux.cfg of a given, bootable iso (of Linux CentOs installation) according to my needs. The things is : I copy the contents of that iso to a different directory. I modify the isolinux.cfg according to my needs. Then what? I had of course googled for it. I had tried afterwards: mkisofs -o centos1.iso -b isolinux/isolinux.bin -no-emul-boot -boot-load-size 4 -boot-i But the result is different: Opening this new iso showed that all sunfolders are uppercase. Moreover, there are files which look like: BOOT.CAT;1 GPL.;1 what is the correct mkisofs command which I should issue in such a case? Is...
