I have the same problem too. The problem appear on FTP and HTTPS requests. There is no problem when our clients are accessing FTP and HTTPS without Squid. I have try to lower MTU for temporary solution. -- Hi all, When trying access ftp sites through one of my squid boxes (squid 2.5 stable 5 on redhat 9), the connection times out. If I try to connect directly, all works fine. I have not made any recent changes to the squid.conf file and cannot understand why it has stopped working. I can ftp from the problem server to any destination. I have copied the squid.conf file a test server and ftp works fine on that box (the test server is 2.5 stable 13). I set the debug mode to 9 and have included a section of cache.log. The process seems to go no further than "ftpStart:" 2006/05/10 10:42:03| parseHttpRequest: URI is 'ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe' Host: ftp.hp.com:21 Host: ftp.hp.com:21 Host: ftp.hp.com:21 2006/05/10 10:42:03| creating entry 0x8c796a0: near 'Host: ftp.hp.com:21' 2006/05/10 10:42:03| created entry 0x8c796a0: 'Host: ftp.hp.com:21' 2006/05/10 10:42:03| aclMatchRegex: checking 'ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe' 2006/05/10 10:42:03| aclMatchRegex: checking 'ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe' 2006/05/10 10:42:03| aclMatchRegex: checking 'ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe' 2006/05/10 10:42:03| ipcache_gethostbyname: 'ftp.hp.com', flags=1 2006/05/10 10:42:03| aclMatchRegex: checking 'ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe' 2006/05/10 10:42:03| The request GET ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe is ALLOWED, because it matched 'non-restricted-users' 2006/05/10 10:42:03| clientRedirectStart: 'ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe' 2006/05/10 10:42:03| clientRedirectDone: 'ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe' result=NULL 2006/05/10 10:42:03| clientProcessRequest: GET 'ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe' 2006/05/10 10:42:03| clientProcessRequest: TCP_MISS for 'ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe' 2006/05/10 10:42:03| clientProcessMiss: 'GET ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe' 2006/05/10 10:42:03| storeCreateEntry: 'ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe' 2006/05/10 10:42:03| storeKeyPrivate: GET ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe 2006/05/10 10:42:03| fwdStart: 'ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe' 2006/05/10 10:42:03| peerSelect: ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe 2006/05/10 10:42:03| peerSelectFoo: 'GET ftp.hp.com' 2006/05/10 10:42:03| peerSelectIcpPing: ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe 2006/05/10 10:42:03| peerGetSomeParent: GET ftp.hp.com 2006/05/10 10:42:03| peerSelectCallback: ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe 2006/05/10 10:42:03| fwdStartComplete: ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe 2006/05/10 10:42:03| fwdConnectStart: ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe 2006/05/10 10:42:03| fd_open FD 201 ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe 2006/05/10 10:42:03| commConnectStart: FD 201, ftp.hp.com:21 2006/05/10 10:42:03| ipcache_nbgethostbyname: Name 'ftp.hp.com'. 2006/05/10 10:42:03| ipcache_nbgethostbyname: HIT for 'ftp.hp.com' 2006/05/10 10:42:03| ipcacheCycleAddr: ftp.hp.com now at 192.6.234.9 2006/05/10 10:42:04| fwdConnectDone: FD 201: 'ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe' 2006/05/10 10:42:04| fwdDispatch: FD 149: Fetching 'GET ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe' 2006/05/10 10:42:04| ftpStart: 'ftp://ftp.hp.com/pub/printers/software/845-enu-xpinfu.exe' 2006/05/10 10:42:04| ftpStart: host=ftp.hp.com, path=/pub/printers/software/845-enu-xpinfu.exe, user=anonymous, passwd=Squid@xxxxxxxxxxxxxxxx Regards Paolo Biancolli -- Lazuardi Nasution Laboratorium Sistem Kendali & Komputer LABTEK 8 Lantai 2 ITB Ganesha 10 Bandung 40132 +628122142597 +622291230584 ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/
