RE: [suse-security] Unencrypted YOU password readable by all
Hi,
From: Kenny [mailto:kenny-sp@uol.com.br] In SUSE 8.2 te pass isn't in this file
Yes, because Mark was talking about SuSE Linux Enterprise Server. You buy one year (or at least 3 months) of maintenance and you get a username and password for the ftp-updates. Mark was referring to this password. And AFAIK YOU is still not capable of connecting to the internet via proxy-servers in 8.2. Regards, Stefan

This might not be the Userid and Password for access to the Linux system itself, but I for one am uncomfortable about leaving such information wide open. At the very least it enables unauthorized use of YOU on another system where the "cracker" may already have root access.
Note this same file can optionally also contain a userid and password for access to a proxy server, which may in fact be more of an exposure.

Hi! YOU can connect to the internet using a proxy. first you have to edit the "wgetrc" file in /etc. enable passive ftp, use proxy on, and the proxy address:port. than retry it in the Yast2 proxy settings, port should be missing. and than edit you /etc/sysconfig files with yast2. there you have also to be shure to have use proxy, passive ftp enabled and that the proxy address and port is correct. after my SuSE 8.2 installation I had to change the wgetrc file, in Yast2 the proxy port was missing, sysconfig i had to change manually to proxy support. strange is that in SuSE 8.1 there was a update to solve the problem. there it was a minor bug, had only to change the wgetrc file, but now i had to controll and correct every file which has to do something with connecting to the net -> thanks to a friend of mine for the 1000 questions I asked him to get it working. hope it helps. could be that I missed a file, misstyped a filename, or forgot a config file I changed -> still a noob greetings Ewald Recher On Mit, 2003-07-09 at 08:58, Peer Stefan wrote:
