Yum version 2.1.11 (Fedora Core 3) Proxy env. variable (http_proxy=http://name:password@xxxxxxxxxxxxxxxxxx:8080/) is set properly, proxy is working, I can download requested files by wget or FireFox without problems, but with yum I got following errors: ---------------------------- BEGIN OF LOG ----------------------------------------------------- [root@darkstar ~]# yum update Setting up Update Process Setting up Repo: base repomd.xml 100% |=========================| 1.1 kB 00:00 Setting up Repo: updates-released repomd.xml 100% |=========================| 951 B 00:00 Reading repository metadata in from local files primary.xml.gz 100% |=========================| 797 kB 00:07 MD Read : ################################################## 2623/2623 base : ################################################## 2622/2622 primary.xml.gz 100% |=========================| 140 kB 00:01 MD Read : ################################################## 351/351 updates-re: ################################################## 351/351 Resolving Dependencies --> Populating transaction set with selected packages.

[root@darkstar ~]# ---------------------------- END OF LOG -------------------------------------------------------- I tried to switch to other mirrors but I always got the same results :-( I've had the chance to run yum with direct connection to Internet and it worked so it has to be a problem with proxy. Any idea, hint ? Is yum using some advanced technique to fetch headers that's incompatible with our basic proxy server ? (Proxy+) Thanks in advance
