problem with dns

Hi, This is a problem that touches some of Fedora services. I've got a network 192.168.101.0 192.168.101.1 - this is my router 192.168.101.200 - ozzy - my F11 server 192.168.101.100 - dio - my Windows 6 workstation I use two DNS servers nameserver 192.168.1.1 nameserver 194.204.159.1 The problem shows up when my network 192.168.101.0 lose a connection with 192.168.1.0 and my primary DNS server is not available. Every time when I try to use samba I get no response from ozzy. Here is what is happening for mc connect(3, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("192.168.1.1")}, 28) = 0 poll([{fd=3, events=POLLOUT}], 1, 0) = 1 ([{fd=3, revents=POLLOUT}]) sendto(3, "Z\253\1\0\0\1\0\0\0\0\0\0\4ozzy\2pl\0\0\1\0\1"..., 25, MSG_NOSIGNAL, NULL, 0) = 25 poll([{fd=3, events=POLLIN}], 1, 5000) = 0 (Timeout) socket(PF_INET, 0x802 /* SOCK_??? */, IPPROTO_IP) = 4 connect(4, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("194.204.159.1")}, 28) = 0 poll([{fd=4, events=POLLOUT}], 1, 0) = 1 ([{fd=4, revents=POLLOUT}]) sendto(4, "Z\253\1\0\0\1\0\0\0\0\0\0\4ozzy\2pl\0\0\1\0\1"..., 25, MSG_NOSIGNAL, NULL, 0) = 25 poll([{fd=4, events=POLLIN}], 1, 5000) = 0 (Timeout) poll([{fd=3, events=POLLOUT}], 1, 0) = 1 ([{fd=3, revents=POLLOUT}]) sendto(3, "Z\253\1\0\0\1\0\0\0\0\0\0\4ozzy\2pl\0\0\1\0\1"..., 25, MSG_NOSIGNAL, NULL, 0) = 25 poll([{fd=3, events=POLLIN}], 1, 5000) = 0 (Timeout) poll([{fd=4, events=POLLOUT}], 1, 0) = 1 ([{fd=4, revents=POLLOUT}]) sendto(4, "Z\253\1\0\0\1\0\0\0\0\0\0\4ozzy\2pl\0\0\1\0\1"..., 25, MSG_NOSIGNAL, NULL, 0) = 25 poll([{fd=4, events=POLLIN}], 1, 5000^C <unfinished ...> Program tries to reach an unreachable server. I have found a workaround - temporary comment all nameservers in resolv.conf. But it's not a solution for a long term. Another instance of this problem is ssh logging - I enter an user name - about a 60 second delay - password prompt appear Yet another problem (when name servers are commented out in resolv.conf) [root@ozzy ~]# yum --enablerepo=updates-testing upgrade Wczytane wtyczki: presto, remove-with-leaves Traceback (most recent call last): File "/usr/bin/yum", line 29, in <module> yummain.user_main(sys.argv[1:], exit_code=True) File "/usr/share/yum-cli/yummain.py", line 311, in user_main errcode = main(args) File "/usr/share/yum-cli/yummain.py", line 180, in main result, resultmsgs = base.doCommands() File "/usr/share/yum-cli/cli.py", line 349, in doCommands self._getTs(needTsRemove) File "/usr/lib/python2.6/site-packages/yum/depsolve.py", line 100, in _getTs self._getTsInfo(remove_only) File "/usr/lib/python2.6/site-packages/yum/depsolve.py", line 111, in _getTsInfo pkgSack = self.pkgSack File "/usr/lib/python2.6/site-packages/yum/__init__.py", line 702, in <lambda> pkgSack = property(fget=lambda self: self._getSacks(), File "/usr/lib/python2.6/site-packages/yum/__init__.py", line 538, in _getSacks self.repos.populateSack(which=repos) File "/usr/lib/python2.6/site-packages/yum/repos.py", line 277, in populateSack sack.populate(repo, mdtype, callback, cacheonly) File "/usr/lib/python2.6/site-packages/yum/yumRepo.py", line 164, in populate if self._check_db_version(repo, mydbtype): File "/usr/lib/python2.6/site-packages/yum/yumRepo.py", line 222, in _check_db_version return repo._check_db_version(mdtype) File "/usr/lib/python2.6/site-packages/yum/yumRepo.py", line 1222, in _check_db_version repoXML = self.repoXML File "/usr/lib/python2.6/site-packages/yum/yumRepo.py", line 1386, in <lambda> repoXML = property(fget=lambda self: self._getRepoXML(), File "/usr/lib/python2.6/site-packages/yum/yumRepo.py", line 1378, in _getRepoXML self._loadRepoXML(text=self) File "/usr/lib/python2.6/site-packages/yum/yumRepo.py", line 1368, in _loadRepoXML return self._groupLoadRepoXML(text, ["primary"]) File "/usr/lib/python2.6/site-packages/yum/yumRepo.py", line 1351, in _groupLoadRepoXML if self._commonLoadRepoXML(text): File "/usr/lib/python2.6/site-packages/yum/yumRepo.py", line 1192, in _commonLoadRepoXML if self._latestRepoXML(local): File "/usr/lib/python2.6/site-packages/yum/yumRepo.py", line 1170, in _latestRepoXML repomd = self.metalink_data.repomd File "/usr/lib/python2.6/site-packages/yum/yumRepo.py", line 699, in <lambda> metalink_data = property(fget=lambda self: self._getMetalink(), File "/usr/lib/python2.6/site-packages/yum/yumRepo.py", line 681, in _getMetalink print "Could not get metalink %s error was \n%s" %(url, e) File "/usr/lib64/python2.6/codecs.py", line 351, in write data, consumed = self.encode(object, self.errors) UnicodeDecodeError: 'ascii' codec can't decode byte 0xc5 in position 197: ordinal not in range(128) I think that such behavior is clearly wrong. But it's a long term issue. So maybe I'm wrong and this is a correct behavior? Regards, Michal
