Fedora Core 2 is now maintained by the Fedora Legacy project for security updates only. If this problem is a security issue, please reopen and reassign to the Fedora Legacy product. If it is not a security issue and hasn't been resolved in the current FC3 updates or in the FC4 test release, reopen and change the version to match. If we modify the maximum number of characters (1024), then we will break compatability with other existing yp clients/servers. See 11.3 on http://www.tldp.org/HOWTO/NIS-HOWTO/maps.html to increase the length of entries, but break compatability with other NIS clients. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; de-AT; rv:1.6) Gecko/20040113 Description of problem: When I update my nis maps (cd /var/yp && make) the longest line from the /etc/group file is rejected with the following words: Updating group.byname... makedbm: warning: data too long and the group-line is printed. It's a line with 1061 characters and a group with 130 members/entries. Lines with more than 1025 characters (counted by wc -c) produce the error. spaces do count, the number of entries seems to be unimportant. The group is NOT included in the nis/yp map :-( You may argue that this is a makedbm problem. I guess the ypserv package has to use a more appropriate db. Version-Release number of selected component (if applicable): ypserv-2.12.1-2 How reproducible: Always Steps to Reproduce: 1. install and configure ypserv and use it for serving groups 2. create a valid group line in /etc/group with more then 1025 characters 3. cd /var/yp && make Actual Results: Group is NOT included in nis/yp map. clients do not get the information which users are in this group, "ypcat group" does not list this group but all others. The clients DO know that this group exists and show group ownership of files (with ls) with the correct name. Expected Results: the group with the long entry should have been included in the nis map. Hey it's only one kilobyte, ypserv is supposed to scale better ;-) Additional info: Well, I have other symptoms related to NIS and do not know whether they are related (but I want to know all about them): 1. once I had a client say "NIS internal error" when I asked something with ypcat (it was either "ypcat group" or "ypcat -x" but it is not reproducable) 2. the server /var/log/messages has errors like: 06:11:06 dateien ypserv[1716]: refused connect from 10.6.1.21:32769 to procedure ypproc_all (NISDOMAINNAME,services.byname;-4) 06:11:06 dateien ypserv[1716]: refused connect from 10.6.1.21:32769 to procedure ypproc_match (NISDOMAINNAME,services.byservicename;-4) 08:45:18 dateien ypserv[1716]: refused connect from 10.6.1.26:32768 to procedure ypproc_match (NISDOMAINNAME,services.byservicename;-4)
